While trying to compile an ASM/SSE/3DNow! optimized FFT on BeOS, using FPC 1.0.8, I instructed to ppc386 to use NASM (because BeOS's gas can't handle SSE), but:
ppc386 -Anasmelf FFT.pas
Warning: Assembler output selected "NASMELF" is not compatible with "BeOS for i386"
Warning: "AS" assembler use forced
FPC 1.9.1 doesn't gives the warning, but it force the use of "as" as the assembler too.
1.9.1 should allow nasmelf for BeOS now as well.
The thing is, BeOS use elf objects, (I already used nasm to compile other programs, i.e. Lame), so it seems to me that FPC shouldn't bail out on this (nasmobj doesn't work because then the linker says: hey! that's not a valid elf object! :-).
Also, the SSE portion of that code has a DQWORD (Delphi recognize it) that FPC doesn't know how to handle (undeclared identifier).
Can you give an example please? I added it but I'am not sure if it works already.
Well, that's all. Thanks for your work.
