From: Matheus Tavares Bernardino <quic_mathbern@quicinc.com>
When there is a conditional change of flow or an endloop instruction, we
preload HEX_REG_PC with ctx->next_PC at gen_start_packet(). Nonetheless,
we still generate TCG code to do this update again at gen_goto_tb() when
the condition for the COF is not met, thus producing redundant
instructions. This can be seen with the following packet:
0x004002e4: 0x5c20d000 { if (!P0) jump:t PC+0 }
Which generates this TCG code:
---- 004002e4
-> mov_i32 pc,$0x4002e8
and_i32 loc9,p0,$0x1
mov_i32 branch_taken,loc9
add_i32 pkt_cnt,pkt_cnt,$0x2
add_i32 insn_cnt,insn_cnt,$0x2
brcond_i32 branch_taken,$0x0,ne,$L1
goto_tb $0x0
mov_i32 pc,$0x4002e4
exit_tb $0x7fb0c36e5200
set_label $L1
goto_tb $0x1
-> mov_i32 pc,$0x4002e8
exit_tb $0x7fb0c36e5201
set_label $L0
exit_tb $0x7fb0c36e5203
Note that even after optimizations, the redundant PC update is still
present:
---- 004002e4
-> mov_i32 pc,$0x4002e8 sync: 0 dead: 0 1 pref=0xffff
mov_i32 branch_taken,$0x1 sync: 0 dead: 0 1 pref=0xffff
add_i32 pkt_cnt,pkt_cnt,$0x2 sync: 0 dead: 0 1 pref=0xffff
add_i32 insn_cnt,insn_cnt,$0x2 sync: 0 dead: 0 1 2 pref=0xffff
goto_tb $0x1
-> mov_i32 pc,$0x4002e8 sync: 0 dead: 0 1 pref=0xffff
exit_tb $0x7fb0c36e5201
set_label $L0
exit_tb $0x7fb0c36e5203
With this patch, the second redundant update is properly discarded.
Note that we need the additional "move_to_pc" flag instead of just
avoiding the update whenever `dest == ctx->next_PC`, as that could
potentially skip updates from a COF with met condition, whose
ctx->branch_dest just happens to be equal to ctx->next_PC.

The following instructions are overriden
S2_ct0 Count trailing zeros
S2_ct1 Count trailing ones
S2_ct0p Count trailing zeros (register pair)
S2_ct1p Count trailing ones (register pair)
These instructions are not handled by idef-parser because the
imported semantics uses bit-reverse. However, they are
straightforward to implement in TCG with tcg_gen_ctzi_*
Test cases added to tests/tcg/hexagon/misc.c

The slot variable in helpers was only passed to log_reg_write function
where the argument is unused.
- Remove declaration from generated helper functions
- Remove slot argument from log_reg_write

Most of these are not modelled in QEMU, so save the overhead of
calling a helper.
The only exception is dczeroa. It assigns to hex_dczero_addr, which
is handled during packet commit.

Currently, idef-parser skips all floating point instructions. However,
there are some floating point instructions that can be handled.
The following instructions are now parsed
F2_sfimm_p
F2_sfimm_n
F2_dfimm_p
F2_dfimm_n
F2_dfmpyll
F2_dfmpylh
To make these instructions work, we fix some bugs in parser-helpers.c
gen_rvalue_extend
gen_cast_op
Test cases added to tests/tcg/hexagon/fpstuff.c

My apologies.
This is the patch causing the error
Hexagon (target/hexagon) Additional instructions handled by idef-parser
I'll have to work with the rev.ng guys to get it fixed.
For now, I'll remove this patch and resubmit the pull request.
Thanks,
Taylor
