x32: Update gcc.target/i386/builtin_thread_pointer.c
Update gcc.target/i386/builtin_thread_pointer.c for x32. For
int
foo3 (int i)
{
int* p = (int*) __builtin_thread_pointer ();
return p[i];
}
we can't generate:
movl %fs:0(,%edi,4), %eax
ret
for x32 since the address of %fs:0(,%edi,4) is %fs + zero-extended to 64
bits of 0(,%edi,4). Instead, we generate:
movl %fs:0, %eax
movl (%eax,%edi,4), %eax
PR target/96955
* gcc.target/i386/builtin_thread_pointer.c: Update scan-assembler
for x32.
