PowerPC running Darwin (Mac OS X kernel).
GCC 3.0 does not support Darwin, but 3.1 and later releases will work.
Pre-installed versions of Mac OS X may not include any developer tools,
meaning that you will not be able to build GCC from source. Tool
binaries are available at
@uref{http://www.opensource.apple.com/projects/darwin/} (free
registration required).
Versions of the assembler prior to ``cctools-364'' cannot handle the
4-argument form of @code{rlwinm} and related mask-using instructions. Darwin
1.3 (Mac OS X 10.0) uses cctools-353 for instance. To get cctools-364,
If you're using Darwin 1.3 (Mac OS X 10.0) or earlier, you will need
to upgrade the assembler to version ``cctools-364''. To get cctools-364,
check out @file{cctools} with tag @samp{Apple-364}, build it, and
install the assembler as @file{usr/bin/as}. See
@uref{http://www.opensource.apple.com/tools/cvs/docs.html} for details.
Also, the default stack limit of 512K is too small, and a bootstrap will
typically fail when self-compiling @file{expr.c}. Set the stack to 800K
or more, for instance by doing @samp{limit stack 800}. It's also
convenient to use the GNU preprocessor instead of Apple's during the
first stage of bootstrapping; this is automatic when doing @samp{make
bootstrap}, but to do it from the toplevel objdir you will need to say
@samp{make CC='cc -no-cpp-precomp' bootstrap}.
The default stack limit of 512K is too small, which may cause compiles
to fail with 'Bus error'. Set the stack larger, for instance
by doing @samp{limit stack 800}. It's a good idea to use the GNU
preprocessor instead of Apple's @file{cpp-precomp} during the first stage of
bootstrapping; this is automatic when doing @samp{make bootstrap}, but
to do it from the toplevel objdir you will need to say @samp{make
CC='cc -no-cpp-precomp' bootstrap}.
Note that the version of GCC shipped by Apple typically includes a
number of extensions not available in a standard GCC release. These
extensions are generally specific to Mac programming.
