This patchset introduces the idef-parser for target/hexagon.
It's the eleventh iteration of the patchset and includes fixes suggested
in previous iterations.
idef-parser is a build-time tool built using flex and bison. Its aim
is to generate a large part of the tiny code generator frontend for
Hexagon. The prototype of idef-parser has been presented at KVM Forum
2019 ("QEMU-Hexagon: Automatic Translation of the ISA Manual Pseudocode
to Tiny Code Instructions"):
https://www.youtube.com/watch?v=3EpnTYBOXCI
target/hexagon/idef-parser/README.rst provides an overview of the
parser and its inner working.
Main changes in v11:
* Patches 8, 9, and 10 adds our build-time dependencies flex, bison, and
a native glib2 to the CI. These have not been reviewed.
* Patch 12 has been added. It introduces some state in CPUHexagonState,
and DisasContext necessary for idef-parser to deal with :mem_noshuf
packets with a store in slot 1 and a predicated load in slot 0.
* Patches 8 and 9 from v10 of the patchset have been dropped. These
dealt with updating libvirt-ci and fixing renamed package templates,
this is already taken care of in upstream.
A couple of notes:
* These commits build successfully on the CI (including using clang),
with one notable exception. Presently, the build-user-hexagon job
fails due to not being able to find flex/bison. This is due to
the debian-hexagon-cross container not being built by the CI.
As such the debian-hexagon-cross container will have to be manually
rebuilt before merging.
* checkpatch.pl complains about the _Generic macro OUT_IMPL in
idef-parser/parser-helpers.h which we believe to be correctly
formatted. The complaints concern the `:` in the type "labels" of the
macro, and also the `default:` label.

Let's start by one of the simplest Hexagon instruction: the ``add``. + +The ISA description language represents the ``add`` instruction as +follows: + +.. code:: c + + A2_add(RdV, in RsV, in RtV) { + { RdV=RsV+RtV;} + } + +idef-parser will compile the above code into the following code: + +.. code:: c + + /* A2_add */ + void emit_A2_add(DisasContext *ctx, Insn *insn, Packet *pkt, TCGv_i32 RdV, + TCGv_i32 RsV, TCGv_i32 RtV) + /* { RdV=RsV+RtV;} */ + { + TCGv_i32 tmp_0 = tcg_temp_new_i32(); + tcg_gen_add_i32(tmp_0, RsV, RtV); + tcg_gen_mov_i32(RdV, tmp_0); + tcg_temp_free_i32(tmp_0); + } + +The output of the compilation process will be a function, containing the +tinycode generator code, implementing the correct semantics. That function will +not access any global variable, because all the accessed data structures will be +passed explicitly as function parameters. Among the passed parameters we will +have TCGv (tinycode variables) representing the input and output registers of +the architecture, integers representing the immediates that come from the code, +and other data structures which hold information about the disassemblation +context (``DisasContext`` struct). + +Let's begin by describing the input code. The ``add`` instruction is associated +with a unique identifier, in this case ``A2_add``, which allows to distinguish +variants of the same instruction, and expresses the class to which the +instruction belongs, in this case ``A2`` corresponds to the Hexagon +``ALU32/ALU`` instruction subclass. + +After the instruction identifier, we have a series of parameters that represents +TCG variables that will be passed to the generated function. Parameters marked +with ``in`` are already initialized, while the others are output parameters. + +We will leverage this information to infer several information: + +- Fill in the output function signature with the correct TCGv registers +- Fill in the output function signature with the immediate integers +- Keep track of which registers, among the declared one, have been + initialized + +Let's now observe the actual instruction description code, in this case: + +.. code:: c + + { RdV=RsV+RtV;} + +This code is composed by a subset of the C syntax, and is the result of the +application of some macro definitions contained in the ``macros.h`` file. + +This file is used to reduce the complexity of the input language where complex +variants of similar constructs can be mapped to a unique primitive, so that the +idef-parser has to handle a lower number of computation primitives. + +As you may notice, the description code modifies the registers which have been +declared by the declaration statements. In this case all the three registers +will be declared, ``RsV`` and ``RtV`` will also be read and ``RdV`` will be +written. + +Now let's have a quick look at the generated code, line by line. + +:: + + TCGv_i32 tmp_0 = tcg_temp_new_i32(); + +This code starts by declaring a temporary TCGv to hold the result from the sum +operation. + +:: + + tcg_gen_add_i32(tmp_0, RsV, RtV); + +Then, we are generating the sum tinycode operator between the selected +registers, storing the result in the just declared temporary. + +:: + + tcg_gen_mov_i32(RdV, tmp_0); + +The result of the addition is now stored in the temporary, we move it into the +correct destination register. This code may seem inefficient, but QEMU will +perform some optimizations on the tinycode, reducing the unnecessary copy. + +:: + + tcg_temp_free_i32(tmp_0); + +Finally, we free the temporary we used to hold the addition result. + +Parser Input +------------ + +Before moving on to the structure of idef-parser itself, let us spend some words +on its' input. There are two preprocessing steps applied to the generated +instruction semantics in ``semantics_generated.pyinc`` that we need to consider. +Firstly, + +:: + + gen_idef_parser_funcs.py + +which takes instruction semantics in ``semantics_generated.pyinc`` to C-like +pseudo code, output into ``idef_parser_input.h.inc``. For instance, the +``J2_jumpr`` instruction which jumps to an address stored in a register +argument. This is instruction is defined as + +:: + + SEMANTICS( \ + "J2_jumpr", \ + "jumpr Rs32", \ + """{fJUMPR(RsN,RsV,COF_TYPE_JUMPR);}""" \ + ) + +in ``semantics_generated.pyinc``. Running ``gen_idef_parser_funcs.py`` +we obtain the pseudo code + +:: + + J2_jumpr(in RsV) { + {fJUMPR(RsN,RsV,COF_TYPE_JUMPR);} + } + +with macros such as ``fJUMPR`` intact. + +The second step is to expand macros into a form suitable for our parser. +These macros are defined in ``idef-parser/macros.inc`` and the step is +carried out by the ``prepare`` script which runs the C preprocessor on +``idef_parser_input.h.inc`` to produce +``idef_parser_input.preprocessed.h.inc``. + +To finish the above example, after preprocessing ``J2_jumpr`` we obtain + +:: + + J2_jumpr(in RsV) { + {(PC = RsV);} + } + +where ``fJUMPR(RsN,RsV,COF_TYPE_JUMPR);`` was expanded to ``(PC = RsV)``, +signifying a write to the Program Counter ``PC``. Note, that ``PC`` in +this expression is not a variable in the strict C sense since it is not +declared anywhere, but rather a symbol which is easy to match in +idef-parser later on. + +Parser Structure +---------------- + +The idef-parser is built using the ``flex`` and ``bison``. + +``flex`` is used to split the input string into tokens, each described using a +regular expression. The token description is contained in the +``idef-parser.lex`` source file. The flex-generated scanner takes care also to +extract from the input text other meaningful information, e.g., the numerical +value in case of an immediate constant, and decorates the token with the +extracted information. + +``bison`` is used to generate the actual parser, starting from the parsing +description contained in the ``idef-parser.y`` file. The generated parser +executes the ``main`` function at the end of the ``idef-parser.y`` file, which +opens input and output files, creates the parsing context, and eventually calls +the ``yyparse()`` function, which starts the execution of the LALR(1) parser +(see `Wikipedia <https://en.wikipedia.org/wiki/LALR_parser>`__ for more +information about LALR parsing techniques). The LALR(1) parser, whenever it has +to shift a token, calls the ``yylex()`` function, which is defined by the +flex-generated code, and reads the input file returning the next scanned token. + +The tokens are mapped on the source language grammar, defined in the +``idef-parser.y`` file to build a unique syntactic tree, according to the +specified operator precedences and associativity rules. + +The grammar describes the whole file which contains the Hexagon instruction +descriptions, therefore it starts from the ``input`` nonterminal, which is a +list of instructions, each instruction is represented by the following grammar +rule, representing the structure of the input file shown above: + +:: + + instruction : INAME arguments code + | error + + arguments : '(' ')' + | '(' argument_list ')'; + + argument_list : argument_decl ',' argument_list + | argument_decl + + argument_decl : REG + | PRED + | IN REG + | IN PRED + | IMM + | var + ; + + code : '{' statements '}' + + statements : statements statement + | statement + + statement : control_statement + | var_decl ';' + | rvalue ';' + | code_block + | ';' + + code_block : '{' statements '}' + | '{' '}' + +With this initial portion of the grammar we are defining the instruction, its' +arguments, and its' statements. Each argument is defined by the +``argument_decl`` rule, and can be either + +:: + + Description Example + ---------------------------------------- + output register RsV + output predicate register P0 + input register in RsV + input predicate register in P0 + immediate value 1234 + local variable EA + +Note, the only local variable allowed to be used as an argument is the effective +address ``EA``. Similarly, each statement can be a ``control_statement``, a +variable declaration such as ``int a;``, a code block, which is just a +bracket-enclosed list of statements, a ``';'``, which is a ``nop`` instruction, +and an ``rvalue ';'``. + +Expressions +~~~~~~~~~~~ + +Allowed in the input code are C language expressions with a few exceptions +to simplify parsing. For instance, variable names such as ``RdV``, ``RssV``, +``PdV``, ``CsV``, and other idiomatic register names from Hexagon, are +reserved specifically for register arguments. These arguments then map to +``TCGv_i32`` or ``TCGv_i64`` depending on the register size. Similarly, ``UiV``, +``riV``, etc. refer to immediate arguments and will map to C integers. + +Also, as mentioned earlier, the names ``PC``, ``SP``, ``FP``, etc. are used to +refer to Hexagon registers such as the program counter, stack pointer, and frame +pointer seen here. Writes to these registers then correspond to assignments +``PC = ...``, and reads correspond to uses of the variable ``PC``. + +Moreover, another example of one such exception is the selective expansion of +macros present in ``macros.h``. As an example, consider the ``fABS`` macro which +in plain C is defined as + +:: + + #define fABS(A) (((A) < 0) ? (-(A)) : (A)) + +and returns the absolute value of the argument ``A``. This macro is not included +in ``idef-parser/macros.inc`` and as such is not expanded and kept as a "call" +``fABS(...)``. Reason being, that ``fABS`` is easier to match and map to +``tcg_gen_abs_<width>``, compared to the full ternary expression above. Loads of +macros in ``macros.h`` are kept unexpanded to aid in parsing, as seen in the +example above, for more information see ``idef-parser/idef-parser.lex``. + +Finally, in mapping these input expressions to tinycode generators, idef-parser +tries to perform as much as possible in plain C. Such as, performing binary +operations in C instead of tinycode generators, thus effectively constant +folding the expression. + +Variables and Variable Declarations +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Similarly to C, variables in the input code must be explicitly declared, such as +``int var1;`` which declares an uninitialized variable ``var1``. Initialization +``int var2 = 0;`` is also allowed and behaves as expected. In tinycode +generators the previous declarations are mapped to + +:: + + int var1; -> TCGv_i32 var1 = tcg_temp_local_new_i32(); + + int var2 = 0; -> TCGv_i32 var1 = tcg_temp_local_new_i32(); + tcg_gen_movi_i32(j, ((int64_t) 0ULL)); + +which are later automatically freed at the end of the function they're declared +in. Contrary to C, we only allow variables to be declared with an integer type +specified in the following table (without permutation of keywords) + +:: + + type bit-width signedness + ---------------------------------------------------------- + int 32 signed + signed + signed int + + unsigned 32 unsigned + unsigned int + + long 64 signed + long int + signed long + signed long int + + unsigned long 64 unsigned + unsigned long int + + long long 64 signed + long long int + signed long long + signed long long int + + unsigned long long 64 unsigned + unsigned long long int + + size[1,2,4,8][s,u]_t 8-64 signed or unsigned + +In idef-parser, variable names are matched by a generic ``VARID`` token, +which will feature the variable name as a decoration. For a variable declaration +idef-parser calls ``gen_varid_allocate`` with the ``VARID`` token to save the +name, size, and bit width of the newly declared variable. In addition, this +function also ensures that variables aren't declared multiple times, and prints +and error message if that is the case. Upon use of a variable, the ``VARID`` +token is used to lookup the size and bit width of the variable. + +Type System +~~~~~~~~~~~ + +idef-parser features a simple type system which is used to correctly implement +the signedness and bit width of the operations. + +The type of each ``rvalue`` is determined by two attributes: its bit width +(``unsigned bit_width``) and its signedness (``HexSignedness signedness``). + +For each operation, the type of ``rvalue``\ s influence the way in which the +operands are handled and emitted. For example a right shift between signed +operators will be an arithmetic shift, while one between unsigned operators +will be a logical shift. If one of the two operands is signed, and the other +is unsigned, the operation will be signed. + +The bit width also influences the outcome of the operations, in particular while +the input languages features a fine granularity type system, with types of 8, +16, 32, 64 (and more for vectorial instructions) bits, the tinycode only +features 32 and 64 bit widths. We propagate as much as possible the fine +granularity type, until the value has to be used inside an operation between +``rvalue``\ s; in that case if one of the two operands is greater than 32 bits +we promote the whole operation to 64 bit, taking care of properly extending the +two operands. Fortunately, the most critical instructions already feature +explicit casts and zero/sign extensions which are properly propagated down to +our parser. + +The combination of ``rvalue``\ s are handled through the use of the +``gen_bin_op`` and ``gen_bin_cmp`` helper functions. These two functions handle +the appropriate compile-time or run-time emission of operations to perform the +required computation. + +Control Statements +~~~~~~~~~~~~~~~~~~ + +``control_statement``\ s are all the statements which modify the order of +execution of the generated code according to input parameters. They are expanded +by the following grammar rule: + +:: + + control_statement : frame_check + | cancel_statement + | if_statement + | for_statement + | fpart1_statement + +``if_statement``\ s require the emission of labels and branch instructions which +effectively perform conditional jumps (``tcg_gen_brcondi``) according to the +value of an expression. Note, the tinycode generators we produce for conditional +statements do not perfectly mirror what would be expected in C, for instance we +do not reproduce short-circuiting of the ``&&`` operator, and use of the ``||`` +operator is disallowed. All the predicated instructions, and in general all the +instructions where there could be alternative values assigned to an ``lvalue``, +like C-style ternary expressions: + +:: + + rvalue : rvalue QMARK rvalue COLON rvalue + +are handled using the conditional move tinycode instruction +(``tcg_gen_movcond``), which avoids the additional complexity of managing labels +and jumps. + +Instead, regarding the ``for`` loops, exploiting the fact that they always +iterate on immediate values, therefore their iteration ranges are always known +at compile time, we implemented those emitting plain C ``for`` loops. This is +possible because the loops will be executed in the QEMU code, leading to the +consequential unrolling of the for loop, since the tinycode generator +instructions will be executed multiple times, and the respective generated +tinycode will represent the unrolled execution of the loop. + +Parsing Context +~~~~~~~~~~~~~~~ + +All the helper functions in ``idef-parser.y`` carry two fixed parameters, which +are the parsing context ``c`` and the ``YYLLOC`` location information. The +context is explicitly passed to all the functions because the parser we generate +is a reentrant one, meaning that it does not have any global variable, and +therefore the instruction compilation could easily be parallelized in the +future. Finally for each rule we propagate information about the location of the +involved tokens to generate pretty error reporting, able to highlight the +portion of the input code which generated each error. + +Debugging +--------- + +Developing the idef-parser can lead to two types of errors: compile-time errors +and parsing errors. + +Compile-time errors in Bison-generated parsers are usually due to conflicts in +the described grammar. Conflicts forbid the grammar to produce a unique +derivation tree, thus must be solved (except for the dangling else problem, +which is marked as expected through the ``%expect 1`` Bison option). + +For solving conflicts you need a basic understanding of `shift-reduce conflicts +<https://www.gnu.org/software/Bison/manual/html_node/Shift_002fReduce.html>`__ +and `reduce-reduce conflicts +<https://www.gnu.org/software/Bison/manual/html_node/Reduce_002fReduce.html>`__, +then, if you are using a Bison version > 3.7.1 you can ask Bison to generate +some counterexamples which highlight ambiguous derivations, passing the +``-Wcex`` option to Bison. In general shift/reduce conflicts are solved by +redesigning the grammar in an unambiguous way or by setting the token priority +correctly, while reduce/reduce conflicts are solved by redesigning the +interested part of the grammar. + +Run-time errors can be divided between lexing and parsing errors, lexing errors +are hard to detect, since the ``var`` token will catch everything which is not +catched by other tokens, but easy to fix, because most of the time a simple +regex editing will be enough. + +idef-parser features a fancy parsing error reporting scheme, which for each +parsing error reports the fragment of the input text which was involved in the +parsing rule that generated an error. + +Implementing an instruction goes through several sequential steps, here are some +suggestions to make each instruction proceed to the next step. + +- not-emitted + + Means that the parsing of the input code relative to that instruction failed, + this could be due to a lexical error or to some mismatch between the order of + valid tokens and a parser rule. You should check that tokens are correctly + identified and mapped, and that there is a rule matching the token sequence + that you need to parse. + +- emitted + + This instruction class contains all the instructions which are emitted but + fail to compile when included in QEMU. The compilation errors are shown by + the QEMU building process and will lead to fixing the bug. Most common + errors regard the mismatch of parameters for tinycode generator functions, + which boil down to errors in the idef-parser type system. + +- compiled + + These instruction generate valid tinycode generator code, which however fail + the QEMU or the harness tests, these cases must be handled manually by + looking into the failing tests and looking at the generated tinycode + generator instruction and at the generated tinycode itself. Tip: handle the + failing harness tests first, because they usually feature only a single + instruction, thus will require less execution trace navigation. If a + multi-threaded test fail, fixing all the other tests will be the easier + option, hoping that the multi-threaded one will be indirectly fixed. + + An example of debugging this type of failure is provided in the following + section. + +- tests-passed + + This is the final goal for each instruction, meaning that the instruction + passes the test suite. + +Another approach to fix QEMU system test, where many instructions might fail, is +to compare the execution trace of your implementation with the reference +implementations already present in QEMU. To do so you should obtain a QEMU build +where the instruction pass the test, and run it with the following command: + +:: + + sudo unshare -p sudo -u <USER> bash -c \ + 'env -i <qemu-hexagon full path> -d cpu <TEST>' + +And do the same for your implementation, the generated execution traces will be +inherently aligned and can be inspected for behavioral differences using the +``diff`` tool. + +Example of debugging erroneous tinycode generator code +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The goal of this section is to provide a complete example of debugging +incorrectly emitted tinycode generator for a single instruction. + +Let's first introduce a bug in the tinycode generator of the ``A2_add`` +instruction, + +:: + + void emit_A2_add(DisasContext *ctx, Insn *insn, Packet *pkt, TCGv_i32 RdV, + TCGv_i32 RsV, TCGv_i32 RtV) + /* RdV=RsV+RtV;} */ + { + TCGv_i32 tmp_0 = tcg_temp_new_i32(); + tcg_gen_add_i32(tmp_0, RsV, RsV); + tcg_gen_mov_i32(RdV, tmp_0); + tcg_temp_free_i32(tmp_0); + } + +Here the bug, albeit hard to spot, is in ``tcg_gen_add_i32(tmp_0, RsV, RsV);`` +where we compute ``RsV + RsV`` instead of ``RsV + RtV``, as would be expected. +This particular bug is a bit tricky to pinpoint when debugging, since the +``A2_add`` instruction is so ubiquitous. As a result, pretty much all tests will +fail and therefore not provide a lot of information about the bug. + +For example, let's run the ``check-tcg`` tests + +:: + + make check-tcg TIMEOUT=1200 \ + DOCKER_IMAGE=debian-hexagon-cross \ + ENGINE=podman V=1 \ + DOCKER_CROSS_CC_GUEST=hexagon-unknown-linux-musl-clang + +In the output, we find a failure in the very first test case ``float_convs`` +due to a segmentation fault. Similarly, all harness and libc tests will fail as +well. At this point we have no clue where the actual bug lies, and need to start +ruling out instructions. As such a good starting point is to utilize the debug +options ``-d in_asm,cpu`` of QEMU to inspect the Hexagon instructions being run, +alongside the CPU state. We additionally need a working version of the emulator +to compare our buggy CPU state against, running + +:: + + meson configure -Dhexagon_idef_parser_enabled=false + +will disable the idef-parser for all instructions and fallback on manual +tinycode generator overrides, or on helper function implementations. Recompiling +gives us ``qemu-hexagon`` which passes all tests. If ``qemu-heaxgon-buggy`` is +our binary with the incorrect tinycode generators, we can compare the CPU state +between the two versions + +:: + + ./qemu-hexagon-buggy -d in_asm,cpu float_convs &> out_buggy + ./qemu-hexagon -d in_asm,cpu float_convs &> out_working + +Looking at ``diff -u out_buggy out_working`` shows us that the CPU state begins +to diverge on line 141, with an incorrect value in the ``R1`` register + +:: + + @@ -138,7 +138,7 @@ + + General Purpose Registers = { + r0 = 0x4100f9c0 + - r1 = 0x00042108 + + r1 = 0x00000000 + r2 = 0x00021084 + r3 = 0x00000000 + r4 = 0x00000000 + +If we also look into ``out_buggy`` directly we can inspect the input assembly +which the caused the incorrect CPU state, around line 141 we find + +:: + + 116 | ---------------- + 117 | IN: _start_c + 118 | 0x000210b0: 0xa09dc002 { allocframe(R29,#0x10):raw } + ... | ... + 137 | 0x000210fc: 0x5a00c4aa { call PC+2388 } + 138 | + 139 | General Purpose Registers = { + 140 | r0 = 0x4100fa70 + 141 | r1 = 0x00042108 + 142 | r2 = 0x00021084 + 143 | r3 = 0x00000000 + +Importantly, we see some Hexagon assembly followed by a dump of the CPU state, +now the CPU state is actually dumped before the input assembly above is ran. +As such, we are actually interested in the instructions ran before this. + +Scrolling up a bit, we find + +:: + + 54 | ---------------- + 55 | IN: _start + 56 | 0x00021088: 0x6a09c002 { R2 = C9/pc } + 57 | 0x0002108c: 0xbfe2ff82 { R2 = add(R2,#0xfffffffc) } + 58 | 0x00021090: 0x9182c001 { R1 = memw(R2+#0x0) } + 59 | 0x00021094: 0xf302c101 { R1 = add(R2,R1) } + 60 | 0x00021098: 0x7800c01e { R30 = #0x0 } + 61 | 0x0002109c: 0x707dc000 { R0 = R29 } + 62 | 0x000210a0: 0x763dfe1d { R29 = and(R29,#0xfffffff0) } + 63 | 0x000210a4: 0xa79dfdfe { memw(R29+#0xfffffff8) = R29 } + 64 | 0x000210a8: 0xbffdff1d { R29 = add(R29,#0xfffffff8) } + 65 | 0x000210ac: 0x5a00c002 { call PC+4 } + 66 | + 67 | General Purpose Registers = { + 68 | r0 = 0x00000000 + 69 | r1 = 0x00000000 + 70 | r2 = 0x00000000 + 71 | r3 = 0x00000000 + +Remember, the instructions on lines 56-65 are ran on the CPU state shown below +instructions, and as the CPU state has not diverged at this point, we know the +starting state is accurate.

(PdV=0xff) : (PdV=0x00); } + +This ternary assignment, when written in this form requires us to emit some +proper control flow statements, which emit a jump to the first or to the second +code block, whose implementation is extremely convoluted, because when matching +the ternary assignment, the code evaluating the two assignments will be already +generated. + +Instead we pre-process that statement, making it become: + +:: + + { PdV = ((PsV==0xff)) ? 0xff : 0x00; } + +Which can be easily matched by the following parser rules: + +:: + + statement | rvalue ';' + + rvalue : rvalue QMARK rvalue COLON rvalue + | rvalue EQ rvalue + | LPAR rvalue RPAR + | assign_statement + | IMM + + assign_statement : pred ASSIGN rvalue + +Another example that highlight the limitation of the flex/bison parser can be +found even in the add operation we already saw: + +:: + + TCGv_i32 tmp_0 = tcg_temp_new_i32(); + tcg_gen_add_i32(tmp_0, RsV, RtV); + tcg_gen_mov_i32(RdV, tmp_0); + +The fact that we cannot directly use ``RdV`` as the destination of the sum is a +consequence of the syntax-driven nature of the parser. In fact when we parse the +assignment, the ``rvalue`` token, representing the sum has already been reduced, +and thus its code emitted and unchangeable. We rely on the fact that QEMU will +optimize our code reducing the useless move operations and the relative +temporaries. + +A possible improvement of the parser regards the support for vectorial +instructions and floating point instructions, which will require the extension +of the scanner, the parser, and a partial re-design of the type system, allowing +to build the vectorial semantics over the available vectorial tinycode generator +primitives. + +A more radical improvement will use the parser, not to generate directly the +tinycode generator code, but to generate an intermediate representation like the +LLVM IR, which in turn could be compiled using the clang TCG backend. That code +could be furtherly optimized, overcoming the limitations of the syntax-driven +parsing and could lead to a more optimized generated code. -- 2.37.0 ^ permalink raw reply related [flat|nested] 26+ messages in thread

Hexagon intructions need access to both the current pc and the next pc, for the generated helper functions this is done through env->gpr[HEX_REG_PC] and `env->next_PC`. However for the TCG code generated by idef-parser we much prefer reading pc and npc from `DisasContext` as these are constant during translation time, we can then "constant fold" by emitting C code for operations on pc and npc instead of TCG code. Secondly, what's IMM_NPC and IMM_PC? This is internal to the parser, but refers to types of immediate values `HexImm`, an immediate with type IMM_NPC can then easily be emitted as `ctx->npc`, similarly IMM_PC gets emitted as `ctx->base.pc_next`. > And why not use target_ulong?
