2011-04-11fix the path to ld.so for darwin/ppc, resolving PR9677. PatchChris Lattner
by Jeremy Huddleston! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129299 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-09refactor -ccc-gcc-name codeDylan Noblesmith
Put the logic for deciding the default name for gcc/g++ in the only place that actually cares about it. This also pushes an ifdef out of the generic driver code to a little further down, when the target is actually known. Hopefully it can be changed into just a runtime check in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129212 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-27Add an option to suppress include stack printing on note diagnostics.Chandler Carruth
These stacks are often less important than those on primary diagnostics. As the number of notes grows, this becomes increasingly important. The include stack printing is clever and doesn't print stacks for adjacent diagnostics from the same file, but when a note is in between a sequence of errors in a header file, and the notes all refer to some other file, we end up getting a worst-case ping-pong of include stacks that take up a great deal of vertical space. Still, for now, the default behavior isn't changed. We can evaluate user feedback with the flag. Patch by Richard Trieu, a couple of style tweaks from me. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128371 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-27Add -f[no-]strict-overflow to the Clang driver. Use it to set theChandler Carruth
default for -fwrapv if that flag isn't specified explicitly. We always prefer an explict setting of -fwrapv when present. Also adds support for -fno-wrapv to allow disabling -fwrapv even when -fno-strict-overflow is passed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128353 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-18Driver: Forward -traditional and -traditional-cpp in preprocessing modes.Daniel Dunbar
- We don't really support the majority of the horrible -traditional-cpp behavior, but it is unlikely that we ever will either. This allows us to start trying to use clang as a /usr/bin/cpp replacement and see what pieces of -traditional-cpp mode people actually care about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127911 91177308-0d34-0410-b5e6-96231b3b80d8
