PS. On Debian, the make-kpkg command has a --rootcmd=sudo option. I am
trying to imagine the equivalent for GCC. Of course on my machine sudo

Would it be a lot faster/easier to create a custom gcc that
has my plug-in compiled in directly for the windows platform?
Depends on how many plugins you use.
The distgcc page says it's reported to work on cygwin.
So you could use a cygwin distgcc to send the compile job

Did you try gcc-4.5 -flto -Os or gcc-4.5 -flto -O2?

Hello,
I am playing around with a plug-in for gcc but recently ran into the
road block that plug-ins aren't supported on Windows. Are there any
plans to add support for the windows platform in the future? If not,

be to add

Thanks for your cooperation,
Richard.

Hello,
I'm working on a new gcc target and trying to implement call_value.
When compiling (-O0 -S) the following c code :
int f1(int a, int b)
{
int tmp = a + b;
return tmp;
}
void main()
{
int a = 10;
int b = 20;
int c;
c = f1(a,b);
}
I get the followi

I have already have both and it still does that.
It seems that after we get here, nothing would stop gcc from emiting
such an invalid insn (tem = emit_insn (gen_move_insn (out, in));). So
I think that maybe the problem is that I got there with these in and
out arguments.
