Hi Steve, Lee, Frederik and others,
The copy of spandsp included in iaxmodem 0.1.4 fails to build on
x86-64.
The asm implementation of bottom_bit() from src/spandsp/alaw_ulaw.h
seems to be buggy:
t38_gateway.c: In function 'non_ecm_putbit_v17':
t38_gateway.c:482: warning: pointer targets in passing argument 4 of
'send_data' differ in signedness
/tmp/cctWzPc2.s: Assembler messages:
/tmp/cctWzPc2.s:1415: Error: Incorrect register `%edx' used with `q' suffix
static __inline__ int bottom_bit(unsigned int bits)
{
int res;
__asm__ __volatile__(" movq $-1,%%rdx;\n"
" bsfq %%eax,%%edx;\n"
line 1415 -----------------^^^^ ^^^^^
: "=d" (res)
: "a" (bits));
return res;
}
My x86-64 asm knowledge is basically zero, so I can't offer a fix
right now :)
bottom_bit() was unused until then, so the bug went unnoticed.
Thanks,
JB.
