Bug ID: 109263
Summary: '-g0 -ggdb -flto' gives linker error
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: lukeocamden at gmail dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Hello,
I have not seen this before!
$ echo 'int main() { }' | g++ -g0 -ggdb -flto -xc++ -
/usr/bin/ld: /tmp/ccgMzjuI.ltrans0.ltrans.o:(.debug_info+0x2f): undefined
reference to `g_stdin_.7138a6a3'
collect2: error: ld returned 1 exit status
$ g++ --version
g++ (Ubuntu 12.1.0-2ubuntu1~22.04) 12.1.0

Unfortunately my build too insists on -g0 so I am using this as a workaround:
$ echo 'int main() { }' | g++ -g0 -g -ggdb -flto -xc++ -
Thanks!

So we stream -g in .lto_options and we do have early LTO debug. But then
nothing combines -g0 -ggdb in the driver so lto-wrapper also sees -g0
and thinks that will prevail, setting skip_debug to true.
Unfortunately -ggdb isn't just -g with "gdb" as arg but an entirely separate
option.
Interestingly -gno-dwarf enables debug info as well.
