Hey chaps,

Inlining doesn't seem to be working in v0.94. I've reduced the problem to this test program because it wasn't inlining a bunch of proper code:


import std.random;

int MulBy2(int a)
{
return a * 2;
}

int main ( char [] [] args )
{
int x = rand();
int y = MulBy2(x);
return y;
}


I'm using this command line:

c:\dmd\bin\dmd.exe test.d -O -release -inline -oftest.exe


And it doesn't inline the call to MulBy2.
Here's the debugger mixed source/disassembly window:


--- test.d --------------------------------------------------------------------

import std.random;

int MulBy2(int a)
00402010  add         eax,eax
{
return a * 2;
}
00402012  ret
00402013  int         3

int main ( char [] [] args )
00402014  push        eax
{
int x = rand();
int y = MulBy2(x);
00402015  call        _D3std6random4randFZk (402114h)
0040201A  call         (402010h)
return y;
}
0040201F  pop         ecx
--- No source file ------------------------------------------------------------
00402020  ret 00402021  int         3 00402022  int         3 00402023  int         3




Why isn't it inlining, please?

Si

Im not sure debug and inline work together, and how did u get embedded debug info without including the proper flags ?

You might want to try compiling to obj and using obj2asm.

C

Right now, initializers aren't inline expanded. So if you wrote:
    int y;
    y = MulBy2(x);
it will inline expand.

Oops, I did actually have the -g flag on the command line as well. I just typed it out wrongly in my post
