Andy Gibbs 3ef5ed1ec0 Provide bootstrap support to build only llvm+clang when using cmake. 
Where a source tree is complete with lld, lldb and polly, it may not be possible to use cmake to configure build scripts if the host compiler it not capable of compiling these sub-projects.  This change makes it possible to first build a bootstrap clang compiler when can then be used to build a complete llvm toolchain.  An example bootstrap build sequence could be as follows:

$ mkdir bootstrap
$ cd bootstrap
$ cmake -G 'Unix Makefiles'
        -DCMAKE_BUILD_TYPE:STRING=Release
        -DCMAKE_PREFIX_PATH:STRING=$(pwd)
        -DLLVM_TARGETS_TO_BUILD:STRING=host
        -DLLVM_INCLUDE_TOOLS:STRING=bootstrap-only
        ../source
$ make clang  # build clang only for host

$ cd ..
$ export CC=$(realpath bootstrap/bin)/clang
$ export CXX=$(realpath bootstrap/bin)/clang++

$ mkdir final
$ cd final
$ cmake -G 'Unix Makefiles' ../source
$ make all check-all

libcxxabi I'd no sooner made the last commit when Matthew Dempsky sent me another test case that led me to yet another closely related test case that the current design could not handle. I've now changed the way forward references are handled completely. It wasn't that much code to change. The demangler, when confronted with a forward reference to a template parameter, now parses things twice. During the second parse, all forward references are remembered from the first parse. Test suite updated with new case. 2013-06-23 19:52:45 +00:00
