Bug ID: 104333
Summary: [11/12 Regression] ICE with -flto
-Wl,-plugin-opt=debug
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
CC: marxin at gcc dot gnu.org
Target Milestone: ---
extern int printf (const char *, ...);
int foo (int arg) { return printf ("hello %d\n", arg); }
int main (int argc) { return foo (argc); }
./xgcc -B ./ -flto -Wl,-plugin-opt=debug rh2048551.c
ICEs
lto1: internal compiler error: in read_cgraph_and_symbols, at
lto/lto-common.cc:2740
0xab4035 read_cgraph_and_symbols(unsigned int, char const**)
../../gcc/lto/lto-common.cc:2740
0xa88d99 lto_main()
../../gcc/lto/lto.cc:625
in GCC 11 and 12, while it correctly complains:
xgcc: error: debug: No such file or directory
in GCC 10.
The reporter meant -Wl,-plugin-opt=-debug which works in all cases, but we
shouldn't ICE even on bad arguments.
