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}.
-
-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.
