#include <stdio.h>

int
main ()
{
  printf ("PASS\n");
  return 0;
}
address@hidden tmp]$ gcc -g -O0 -Wa,-mx86-used-note=no -c
/export/gnu/import/git/sources/binutils-gdb/ld/testsuite/ld-x86-64/pass.c
address@hidden tmp]$ gcc -g -O0 -Wa,-mx86-used-note=no 
/export/gnu/import/git/sources/binutils-gdb/ld/testsuite/ld-x86-64/pass.c
address@hidden tmp]$ readelf -n a.out > /dev/null
readelf: Warning: Gap in build notes detected from 0x401127 to 0x40113f
address@hidden tmp]$ gcc -g -O2 -Wa,-mx86-used-note=no 
/export/gnu/import/git/sources/binutils-gdb/ld/testsuite/ld-x86-64/pass.c

-O0 triggers "Warning: Gap in build notes detected from 0x401127 to 0x40113".
