Sadly the latest optimization broke completely everything.
The asm code isn't gas compliant. the libFLAC linker script has a typo, disabling the asm optimization and/or altivec won't let a correct build anyway.
Instant fixes for the asm stuff:
sed -i -e"s:;:\#:" on the lpc_asm.s
to load address instead of addis+ori you could use
lis and la and PLEASE use the @l(register) and @ha macros instead of the not gas supported hi/lo16().
eg:
lis 31,[EMAIL PROTECTED] la 31,[EMAIL PROTECTED](31)
append use -mregnames as as options (remove the other)
(the option there isn't present in the as manual, and I could just try to figure what's supposed to do)
there are -rpath $(libdir) when -rpath,$(libdir) should be used
in src/libFLAC/Makefile
libFLAC.la: $(libFLAC_la_OBJECTS) $(libFLAC_la_DEPENDENCIES)
$(LINK) -rpath $(libdir) $(libFLAC_la_LDFLAGS)
$(libFLAC_la_OBJECTS) $(libFLAC_la_LIBADD) $(LIBS)the final build still doesn't link correctly (the 2 altivec asm function aren't properly linked in, I haven't the time to investigate the issue yet=/)
More verbose report about the no altivec bug:
If I disable altivec optimization (with --disable-asm-optimizations --disable-altivec)
the result is:
stream_decoder.c: In function `FLAC__stream_decoder_init':
stream_decoder.c:296: error: `FLAC__lpc_restore_signal' undeclared (first use in this function)
stream_decoder.c:296: error: (Each undeclared identifier is reported only once
stream_decoder.c:296: error: for each function it appears in.)
stream_decoder.c:297: error: `FLAC__lpc_restore_signal_wide' undeclared (first use in this function)
make[4]: *** [stream_decoder.lo] Error 1
make[4]: Leaving directory `/var/tmp/portage/flac-1.1.1/work/flac-1.1.1/src/libFLAC'
Could you please at least make sure that disabling altivec optimization won't break the build?
That's a bit higher whish:
could you please write the altivec optimization using C intrinsics? That way they should work with no/little modification even on ppc 970 in ppc64 mode.
