[Qemu-devel] [PULL 00/18] misc cross-tree patches queue

[Peter Maydell]

Hi; this pullreq gathers up a set of patches I've sent recently which
have got code review but fall between stools somewhat because they
touch files in various places across the tree; it seemed easiest
just to put them all in a pullrequest and send it out.

thanks

[Qemu-devel] [PULL 01/18] scripts/qapi-types.py: Add dummy member to empty structs

[Peter Maydell]

Make sure that all generated C structs have at least one field; this
avoids potential issues with attempting to malloc space for
zero-length structs in C (g_malloc(sizeof struct) would return NULL).
It also avoids an incompatibility with C++ (where an empty struct is
size 1); that isn't important to us now but might be in future.

Generated empty structures look like this:
    struct Abort
    {
        char qapi_dummy_field_for_empty_struct;
    };

This silences clang warnings like:
./qapi-types.h:3752:1: warning: empty struct has size 0 in C, size 1 in C++ [-Wextern-c-compat]
struct Abort
^

[Qemu-devel] [PULL 02/18] exec.c: Drop TARGET_HAS_ICE define and checks

[Peter Maydell]

The TARGET_HAS_ICE #define is intended to indicate whether a target-*
guest CPU implementation supports the breakpoint handling. However,
all our guest CPUs have that support (the only two which do not
define TARGET_HAS_ICE are unicore32 and openrisc, and in both those
cases the bp support is present and the lack of the #define is just
a bug). So remove the #define entirely: all new guest CPU support
should include breakpoint handling as part of the basic implementation.

[Qemu-devel] [PULL 03/18] cpu_ldst.h: Remove unused ldul_ macros

[Peter Maydell]

The five ldul_ macros are not used anywhere and are marked up with an XXX
comment. "ldul" is a non-standard prefix for our family of load instructions:
we don't mark 32-bit accesses for signedness because they return a 32 bit
quantity. So just delete them.

[Qemu-devel] [PULL 04/18] monitor.c: Use ld*_p() instead of ld*_raw()

[Peter Maydell]

The monitor code for doing a memory_dump() was using ld*_raw() to do
target-CPU accesses out of a local buf[] array. The correct functions
for this purpose are ld*_p(), which take a host pointer, rather than
ld*_raw(), which take an integer representing a guest address and
are somewhat meaningless in softmmu configurations. Nobody noticed
because for softmmu the _raw functions are the same as ldl_p but
with some extra casts thrown in. Switch to using the correct functions
instead.

[Qemu-devel] [PULL 05/18] target-sparc: Don't use {ld, st}*_raw functions

[Peter Maydell]

Instead of using the _raw family of ld/st accessor functions, use
cpu_*_data. All this code is CONFIG_USER_ONLY, so the two are the
same semantically, but the _raw functions are really a detail of
the implementation which has leaked into a few callsites like this one.

Use get_user_u64() and get_user_ual() instead of the ldl() and

[Note that this change is not compile tested as it is actually
in dead code -- none of the bsd-user configurations are PPC.]

[Qemu-devel] [PULL 13/18] cpu_ldst.h: Use inline functions for usermode cpu_ld/st accessors

[Peter Maydell]

Use inline functions rather than macros for cpu_ld/st accessors
for the *-user configurations, as we already do for softmmu.
This has a two advantages:
 * we can actually typecheck our arguments
 * we don't need to leak the _raw macros everywhere

Since the _kernel functions were only used by target-i386/seg_helper.c,
put the definitions for them in that file too. (It already has the
similar template include code to define them for the softmmu case,
so it makes sense to have it deal with defining them for user-only.)

[Qemu-devel] [PULL 14/18] cpu_ldst_template.h: Use ld*_p directly rather than via ld*_raw macros

[Peter Maydell]

The ld*_raw and st*_raw macros are now only used within the code
produced by cpu_ldst_template.h, and only in three places.
Expand these out to just call the ld_p and st_p functions directly.

Note that in all the callsites the address argument is a uintptr_t,
so we can drop that part of the double-cast used in the saddr() and
laddr() macros.

The cpu_ldfq/stfq/ldfl/stfl accessors for loading and storing
float32 and float64 are completely unused, so delete them.
(The union they use for converting from the float32/float64

they should be using make_float* and float*_val.)

[Qemu-devel] [PULL 17/18] cpu_ldst.h, cpu-all.h, bswap.h: Update documentation on ld/st accessors

[Peter Maydell]

Add documentation of what the cpu_*_* accessors look like.
Correct some minor errors in the existing documentation of the
direct _p accessor family. Remove the near-duplicate comment
on the _p accessors from cpu-all.h and replace it with a reference
to the comment in bswap.h.

[Qemu-devel] [PULL 18/18] cpu_ldst.h: Don't define helpers if MMU_MODE*_SUFFIX not defined

[Peter Maydell]

Not all targets define a full set of suffix strings for the
NB_MMU_MODES that they have. In this situation, don't define any
helper functions for that mode, rather than defining helper functions
with no suffix at all. The MMU mode is still functional; it is merely
not directly accessible via cpu_ld*_MODE from target helper functions.

Also add an "NB_MMU_MODES >= 2" check to the definition of the mode 1
helpers -- some targets only define one MMU mode.
