Bug ID: 29291
Summary: ld-ctf/data-func-conflicted*.d FAIL with -g3 -O0
Product: binutils
Version: 2.39 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: libctf
Assignee: unassigned at sourceware dot org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: amd64--c-solaris2.11, x86_64-pc-linux-gnu
When investigating a different CTF issue on Solaris, I built binutils trunk
with
gcc 12.1.0 -g3 -O0. This caused two CTF tests to FAIL that PASS with the
regular
-g -O2:
FAIL: Conflicted data syms, partially indexed, stripped, with variables
FAIL: Conflicted data syms, partially indexed, stripped
ld.log shows
regexp_diff match failure
regexp "^ Variable section: .* \(0x10 bytes\)$"
line " Variable section: 0x5c -- 0x73 (0x18 bytes)"
regexp_diff match failure
regexp "^ Type section: .* \(0x118 bytes\)$"
line " Type section: 0x74 -- 0x197 (0x124 bytes)"
regexp_diff match failure
regexp "^ funcs -> .*$"
line " foo -> 0xf: (kind 5) void *(*) () (aligned at 0x8)"
regexp_diff match failure
regexp "^ other_func -> .*$"
line " funcs -> 0xe: (kind 4) void **([16])(*) (const char *restrict, int
(*)(*) (const char *)) (size 0x80) (aligned at 0x8) -> 0xc: (kind 3) void **(*)
(const char *restrict, int (*)(*) (const char *)) (size 0x8) (aligned at 0x8)
-> 0xb: (kind 5) void *(*) (const char *restrict, int (*)(*) (const char *))
(aligned at 0x8)"

Seen on Solaris/amd64 and Linux/x86_64, probably generic.
