Flac uses assembly code to improve performance for ix86 processors. This
works under Linux, BSD and Windows, but not Mac OS X, because there is
no support for creating Mach-O format binaries (the native binary format
for OS X systems). The attached patch provides the necessary support to
create ASM-optimised Mach-O binaries.
This wasn't created by me but was sent to the audacity-devel list (I
think by Matthew Sachs <matthewg@zevils.com>) as a patch against 1.1.2,
then tweaked to apply to the 1.2.1 release.
There is also a problem with text relocation's in the assembly binary,
which require an executable stack on ELF system. Gentoo has a patch to
resolve the problem on their build which seems to work. I can't see
anything relevant in the Sourceforge tracker on these two issues, but I
may be wrong.
