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?

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.

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

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