Bug ID: 109854
Summary: Error: junk `(%rip)' after expression when using -flto
on files compiled with and without -masm=intel
Product: gcc
Version: 13.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: bouanto at zoho dot com
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Hi.
With those two source files:
a.c:
#include <stdio.h>
void a(void) {
puts("A");
}
main.c:
void a(void);
int main(void) {
a();
return 0;
}
and by running the following commands:
gcc -c -flto a.c # Note the absence of -masm=intel
gcc -masm=intel -O3 -flto a.o main.c -o main
I get the following error:
/tmp/cca9LQNs.s: Assembler messages:
/tmp/cca9LQNs.s:17: Error: junk `(%rip)' after expression
lto-wrapper: fatal error: gcc returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status
Compiling the a.c file with -masm=intel solves the issue.
(Doing the opposite, that is compiling a.c with -masm=intel and main.c without
gives a different error: /usr/bin/ld: /tmp/ccMwJTwN.ltrans0.ltrans.o:
relocation R_X86_64_32S against undefined symbol `$8' can not be used when
making a PIE object; recompile with -fPIE
Please tell me if you want me to open a different issue for this case.)
Thanks to fix this issue.
