- Entry point is tools/ccc/xcc until we are a functional replacement for ccc. This is highly experimental (FIXME/LOC ratio of 3.4%), quite crufty, and barely usable (and then only on my specific Darwin). However, many of the right ideas are present, and it already fixes a number of things gcc gets wrong. The major missing component is argument translation for tools (translating driver arguments into cc1/ld/as/etc. arguments). This is a large part of the driver functionality and will probably double the LOC, but my hope is that the current architecture is relatively stable. Documentation & motivation to follow soon... llvm-svn: 61739
