Hello, Is it possible for an ASM function to be inlined in D?
for example I compile with -Release -inline, this function (used
in a simple console app obviously):
---
int SSERound(double AValue)
{
asm
{
cvtsd2si EAX,[AValue];
}
}
---
but, under win32, the code generated looks like this:
---
sub_402010 proc near ; CODE XREF:
_TEXT:0040209Dp
_TEXT:00402010
_TEXT:00402010 arg_0 = qword ptr 8
_TEXT:00402010
_TEXT:00402010 push ebp
_TEXT:00402011 mov ebp, esp
_TEXT:00402013 cvtsd2si eax, [ebp+arg_0]
_TEXT:00402018 pop ebp
_TEXT:00402019 retn 8
_TEXT:00402019 sub_402010 endp
---
Which looks a bit odd as there is a CALL, a PUSH, a POP and a RET
just for one SSE instruction.
I've tried with "naked", but I've fastly get that this keyword
simply mean that it's up to the user to clean the regs or to push
pop the wtacks etc.
Can dmd "inline" this simple function ? the D manual doesn't seem
to specify that there is a restriction over inlining when a
function contains an asm block.
