I can not reproduce it on the current trunk (rev. 182263). The recent ira
patches might fix it. The code generated on the current trunk is
pushl %ebp
.cfi_def_cfa_offset 8
.cfi_offset 5, -8
movl %esp, %ebp
.cfi_def_cfa_register 5
pushl %edi
.cfi_offset 7, -12
movl $1024, %ecx
xorl %eax, %eax
movl 8(%ebp), %edi
rep stosl
movl 8(%ebp), %eax
movl $0, 4096(%eax)
popl %edi
.cfi_restore 7
popl %ebp
.cfi_restore 5
.cfi_def_cfa 4, 4
