- Subject: [ECOS] code questions:
here is a assemble subroutine of PPC:
#define HAL_LSBIT_INDEX(index, mask) \
asm ( "neg 11,%1;" \
"and 11,11,%1;" \
"cntlzw %0,11;" \
"subfic %0,%0,31;" \
: "=r" (index) \
: "r" (mask) \
: "r11" \
);
could you tell me means of such as %1,%0,:,"=r" and so on, and where to get more info?
i search them in processor mannul and gnu toolkit to look for them,but failed.
