Hi!
I'm finding libmad's compilation fails on cfarm230.cfarm.net, an
EdgeRouter4 (big-endian)
mips64
Cavium Octeon III V0.2 FPU V0.0
Debian 10.13 buster 4.9.79-UBNT_E300
with
gcc (Debian 8.3.0-6) 8.3.0
saying
In file included from layer12.c:34:
layer12.c: In function 'I_sample':
fixed.h:307:5: error: impossible constraint in 'asm'
asm ("mult %2,%3" \
^~~
fixed.h:455:8: note: in expansion of macro 'MAD_F_MLX'
MAD_F_MLX(__hi, __lo, (x), (y)); \

layer12.c:94:10: note: in expansion of macro 'mad_f_mul'
return mad_f_mul(sample, linear_table[nb - 2]);
^~~~~~~~~
make[2]: *** [Makefile:383: layer12.lo] Error 1
If I configure with --disable-osa instead I get the same error and it needs
./configure --enable-fpm=default
to work.
Am I missing something, or is that what it should do?
