Subject: [Bug debug/99090] New: gsplit-dwarf broken on riscv64-linux
Date: Sat, 13 Feb 2021 21:20:42 +0000 [thread overview]
Message-ID: <bug-99090-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99090
Bug ID: 99090
Summary: gsplit-dwarf broken on riscv64-linux
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: wilson at gcc dot gnu.org
Target Milestone: ---
Enabling -gsplit-dwarf by default and trying a build hits an assert in
dw2_asm_output_delta_uleb128 because HAVE_AS_LEB128 is not defined.
The problem appears to be in output_loc_list in dwarf2out.c which has in the
dwarf_split_debug_info code
/* FIXME: This will ICE ifndef HAVE_AS_LEB128.
For that case we probably need to emit DW_LLE_startx_endx,
but we'd need 2 .debug_addr entries rather than just one. */
riscv doesn't allow leb128 because of agressive linker relaxation, so we need
the alternative solution here that works without HAVE_AS_LEB128.
