On alpha, multimedia/libmpeg2 passes -Wa,-mev6 to the compiler in order to be able to build MVI code. However, if -mcpu=XXX is passed in CFLAGS (e.g. from setting CPUTYPE in /etc/mk.conf), it will override the CPU type. If that CPU model does not support MVI, the build will fail: cc -DHAVE_CONFIG_H -I. -I. -I../include -I../include -I../include -pipe -mcpu=ev56 -Wall -fomit-frame-pointer -Wa,-mev6 -MT idct_alpha.lo -MD -MP -MF .deps/idct_alpha.Tpo -c idct_alpha.c -o .libs/idct_alpha.lo ../include/alpha_asm.h:69: warning: `WORD_VEC' defined but not used {standard input}: Assembler messages: {standard input}:969: Error: opcode `maxsw4' not supported for target ev56 {standard input}:975: Error: opcode `minsw4' not supported for target ev56 {standard input}:981: Error: opcode `pkwb' not supported for target ev56 [...] Whether MVI code is actually used is chosen at run time. This is strictly a build time issue.
