The testcase, referred in Comment 0 is:
struct _Unwind_Context
{
void *reg[17];
void *ra;
};
extern void bar (struct _Unwind_Context *);
void
__frame_state_for (void *pc_target)
{
struct _Unwind_Context context;
__builtin_memset (&context, 0, sizeof (struct _Unwind_Context));
context.ra = pc_target;
bar (&context);
}
Compiling with recent mainline works OK:
~/gcc-build/gcc/cc1 -O2 -fpic -mx32 pr47725.c
__frame_state_for:
.LFB0:
.cfi_startproc
subq $88, %rsp
.cfi_def_cfa_offset 96
movq %rdi, %rsi
xorl %eax, %eax
movq %rsp, %rdi
movl $9, %ecx
rep stosq
movq %rsp, %rdi
movl %esi, 68(%rsp)
call bar@PLT
addq $88, %rsp
.cfi_def_cfa_offset 8
ret
Fixed.
