FWIW, the bogus assert can be triggered on other platforms too. c6x-elf for example with -mbig-endian. I don't know enough about this code to review. jeff

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); ? > gcc/ChangeLog: > > PR debug/103619 > * dwarf2cfi.c (dwf_cfa_reg): Remove gcc_assert. > --- > gcc/dwarf2cfi.c | 1 - > 1 file changed, 1 deletion(-) > > diff --git a/gcc/dwarf2cfi.c b/gcc/dwarf2cfi.c > index 9dd1dfe71b7..55ae172eda2 100644 > --- a/gcc/dwarf2cfi.c > +++ b/gcc/dwarf2cfi.c > @@ -1136,7 +1136,6 @@ dwf_cfa_reg (rtx reg) > gcc_assert (GET_MODE_SIZE (GET_MODE (XVECEXP (span, 0, i))) > .to_constant () == result.span_width); > gcc_assert (REG_P (XVECEXP (span, 0, i))); > - gcc_assert (dwf_regno (XVECEXP (span, 0, i)) == result.reg + i); > } > } > } Jakub
