--- Comment #1 from Simon Pilgrim <[email protected]> ---
This is fixed in trunk, I think from the work on [Bug #40483]
trunk / 9.0:
wider_tests::Tests<unsigned __int128>::neg(unsigned __int128*):
xorl %eax, %eax
negq (%rdi)
sbbq 8(%rdi), %rax
movq %rax, 8(%rdi)
retq
wider_tests::Tests<Wider<unsigned long> >::neg(Wider<unsigned long>*):
xorl %eax, %eax
negq (%rdi)
sbbq 8(%rdi), %rax
movq %rax, 8(%rdi)
retq
vs 8.0:
wider_tests::Tests<unsigned __int128>::neg(unsigned __int128*):
xorl %eax, %eax
xorl %ecx, %ecx
subq (%rdi), %rcx
sbbq 8(%rdi), %rax
movq %rcx, (%rdi)
movq %rax, 8(%rdi)
retq
wider_tests::Tests<Wider<unsigned long> >::neg(Wider<unsigned long>*):
movq (%rdi), %rax
testq %rax, %rax
setne %cl
negq %rax
xorl %edx, %edx
addb $-1, %cl
sbbq 8(%rdi), %rdx
movq %rax, (%rdi)
movq %rdx, 8(%rdi)
retq
