--- Comment #12 from Tobias Schlüter <tobi at gcc dot gnu.org> ---
Because I posted 32bit code before, here is what the trunk does with -m32
func34(m34):
fld DWORD PTR [esp+8]
mov eax, DWORD PTR [esp+4]
fstp QWORD PTR [eax]
fld DWORD PTR [esp+24]
fstp QWORD PTR [eax+8]
fld DWORD PTR [esp+40]
fstp QWORD PTR [eax+16]
fld DWORD PTR [esp+12]
fstp QWORD PTR [eax+24]
fld DWORD PTR [esp+28]
fstp QWORD PTR [eax+32]
fld DWORD PTR [esp+44]
fstp QWORD PTR [eax+40]
fld DWORD PTR [esp+16]
fstp QWORD PTR [eax+48]
fld DWORD PTR [esp+32]
fstp QWORD PTR [eax+56]
fld DWORD PTR [esp+48]
fstp QWORD PTR [eax+64]
fld DWORD PTR [esp+20]
fstp QWORD PTR [eax+72]
fld DWORD PTR [esp+36]
fstp QWORD PTR [eax+80]
fld DWORD PTR [esp+52]
fstp QWORD PTR [eax+88]
ret 4
This is the same as the assembly from 9.3 in Comment 4.
