The only snag with that approach is that you can't straightforwardly crunch the program - you need to offload the assembler code into a separate file, with an extension other than .BBC, that you CALL at run time. |

Thanks, I'll look into it.

My usual command line compilation instruction:
Code:gcc -c -O2 -march=native -o glib2.o glib2.c
Followed by (for compiling the DLL):
Code:gcc -o glib2.dll -s -shared glib2.o -Wl,--subsystem,windows
With regards C and compilation, I'm extremely 'green' having been at this for all of 2 weeks, so far.
Can't say I've noticed any SSE2 instructions in the GCC-generated assembler code, but then I haven't done that much on that side of things.
Shall I say it before you do? "This is off-topic for this thread".
Thought I'd beat you to it. :)
