Bug ID: 81523
Summary: -static -pie behaves differently depending on if
--enable-default-pie is used
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: hjl.tools at gmail dot com
Blocks: 81170, 81498
Target Milestone: ---
[hjl@gnu-tools-1 tmp]$ cat x.c
#include <stdio.h>
int
main ()
{
printf ("hello\n");
return 0;
}
[hjl@gnu-tools-1 tmp]$ /mnt/test/usr/gcc-7.1.1-x32-pie/bin/gcc -static -pie
-fPIE x.c
[hjl@gnu-tools-1 tmp]$ /mnt/test/usr/gcc-7.1.1-x32/bin/gcc -static -pie -fPIE
x.c
/usr/local/bin/ld:
/mnt/test/usr/gcc-7.1.1-x32/bin/../lib/gcc/x86_64-pc-linux-gnu/7.1.1/crtbeginT.o:
relocation R_X86_64_32 against hidden symbol `__TMC_END__' can not be used when
making a shared object
/usr/local/bin/ld: /lib/../lib64/libc.a(libc-start.o): relocation R_X86_64_32
against symbol `_dl_starting_up' can not be used when making a shared object;
recompile with -fPIC
...
When gcc is configured with --enable-default-pie, -static completely overrides
-pie. When gcc is configured without --enable-default-pie, -static partially
overrides -pie.
