I have tried new daily snapshot, and with some patches, asm code runs
well.
- Both nasm 2.5.1 and yasm 0.7.2.2153 work well.
Would you please apply a-bit codes for MacOSX specific issue?
//
1) It still requires section name as ".text", not ".rotext"
Requires rename section for Mach-O binary; ifdef macro would be better
though
vi ../../src/nasm.inc
%macro TEXT 0
- SECTION .rotext align=SECTION_ALIGN
+ SECTION .text align=SECTION_ALIGN
%endmacro
2) MacOSX-i386 specific alignment patch
Requires alignment to avoid segfault (http://trac.handbrake.fr/changeset/1315
)
vi ../../src/dct/x86_asm/fdct_sse2_skal.asm
ENDFUNC
+ALIGN SECTION_ALIGN
+ times 8 dw 0
+
%ifidn __OUTPUT_FORMAT__,elf
section ".note.GNU-stack" noalloc noexec nowrite progbits
%endif
3) MacOSX-PPC specific patch
Apple GCC still requires -arch ppc for cross compile(=universal binary)
(http://forum.doom9.org/showthread.php?t=142556)
modify 3 line as "-faltivec" with " -arch ppc -faltivec".
