Commit 13b6c7639cf assumed that registers in a span will be in a certain
order. But that assumption is not true at least for the big endian targets.
Currently amdgcn is probably only target where CFA is split into multiple
registers so build_span_loc is only gets called for it. However, the
dwf_cfa_reg function where this ICE was seen can be called for any
architecture from the comparison dwf_cfa_reg (src) == cur_cfa->reg in
dwarf2out_frame_debug_expr. So dwf_cfa_reg should not assume certain
order of registers.
I was tempted to modify the assert to handle big-endian cases but that will
still be error prone and may fail on some other targets.
Do you have a preprocessed testcase on which the ICE triggers on ARM EB?
I think I'd like to see what we were emitting in debug info for it before
r12-5833 and what we emit with this assert removed after it.
I assumed it wouldn't affect anything but GCN during the review.
Seems the arm span hook for EB will swap pairs in the list:
for (i = 0; i < nregs; i += 2)
if (TARGET_BIG_END)
{
parts[i] = gen_rtx_REG (SImode, regno + i + 1);
parts[i + 1] = gen_rtx_REG (SImode, regno + i);
}
BTW, I wonder about those
dw_stack_pointer_regnum = dwf_cfa_reg (gen_rtx_REG (Pmode,
STACK_POINTER_REGNUM));
and
dw_frame_pointer_regnum
= dwf_cfa_reg (gen_rtx_REG (Pmode, HARD_FRAME_POINTER_REGNUM));
Can't those use
dw_stack_pointer_regnum = dwf_cfa_reg (stack_pointer_rtx);
and
dw_frame_pointer_regnum = dwf_cfa_reg (hard_frame_pointer_rtx);
?
I think the attached testcase should trigger on c6x with -mbig-endian -O2 -g
