ok so I added
: : "rax"

ok but...

now

jpeg_color_mmx.cpp: In function ‘void jpeg_yh2v2_to_rgb32_mmx(unsigned char*, long int, unsigned char*)’:
jpeg_color_mmx.cpp:474: error: can't find a register in class ‘AREG’ while reloading ‘asm’
jpeg_color_mmx.cpp:474: error: ‘asm’ operand has impossible constraints

so it seems that there is not enought register for this operation. I am right ?

must I use another register or do a push rax ... pop rax to solve this problem
