--- Comment #6 from Martin Liska <mliska at suse dot cz> --- Sorry for not precise reproducer. I was reducing that from an existing package that normally succeeds w/o LTO. So what about this: $ cat main.i int wrl; int main () { return 0; } $ cat lib.i int wrl; void a() {} $ gcc -c main.i && gcc -c lib.i && ar rusc lib.a lib.o && gcc main.o lib.a lib.a This works fine, however: $ gcc -c -flto main.i && gcc -c -flto lib.i && ar rusc lib.a lib.o && gcc main.o lib.a lib.a -flto --save-temps lto1: fatal error: multiple prevailing defs for ‘a’ compilation terminated. lto-wrapper: fatal error: gcc returned 1 exit status compilation terminated. /usr/lib64/gcc/x86_64-suse-linux/8/../../../../x86_64-suse-linux/bin/ld: error: lto-wrapper failed collect2: error: ld returned 1 exit status $ cat lib.res 3 main.o 2 198 5dfd76773c77e89 PREVAILING_DEF main 202 5dfd76773c77e89 PREVAILING_DEF_IRONLY wrl lib.a@0x92 2 198 e65cc6ac1d79da7a PREVAILING_DEF_IRONLY a 202 e65cc6ac1d79da7a RESOLVED_IR wrl lib.a@0x92 2 198 e65cc6ac1d79da7a PREVAILING_DEF_IRONLY a 202 e65cc6ac1d79da7a RESOLVED_IR wrl Hope it's fine test-case? -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
