2010-09-17Driver: implement driver automagic support for -lcc_kextShantonu Sen
Rewrite linker arguments to use libclang_rt.cc_kext.a instead of gcc-specific libcc_kext.a Resolves Radar 7808495 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114193 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-17Add a -ftrapv-handler= option which allows a handler to invoke instead of ↵David Chisnall
simply aborting when a signed operation overflows. This mirrors the (GCC-incompatible) behaviour from clang 1.0 and 1.1 when -ftrapv was specified, but allows the handler to be defined for each compilation unit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114192 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-17Driver: Fix spelling of AddCXXStdlibLibArgs, which I copy-n-pasto'd.Daniel Dunbar

2010-09-17Driver/DarwinClang: The new toolchain definition is going to drop the -L insideDaniel Dunbar
the GCC dir. Unfortunately, this breaks -lstdc++ on SnowLeopard, etc. because the libstdc++ dylib was hiding there. Workaround this by providing the path to the right -lstdc++.6 (the only version used in recent memory) if we can't see an obvious -lstdc++, but can find = -lstdc++.6. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114146 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-17Driver: Add magic handling for "reserved library names", starting withDaniel Dunbar
-lstdc++. This is the best gross solution for a gross problem. This issue is that historically, GCC has add -L options to its internally library directories. This has allowed users and platforms to end up depending on the layout of GCC's internal library directories. We want to correct this mistake by eliminating that -L, but this means that existing libraries which are in the GCC lib dir won't be found. We are going to handle this by treating those -l names as "reserved", and requiring toolchains to know how to add the right full path to the reserved library. The immediately side effect of this is that users trying to use -L to find their own -lstdc++ will need to start using -nostdlib (which is a good idea anyway). Another side effect is that -stdlib=libc++ -lstdc++ will now do the "right" thing, for curious definitions of right. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114144 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-14Driver: Add a -stdlib= argument which can be used to select the C++ standardDaniel Dunbar
library to use. - This is currently useful for testing libc++; you can now use 'clang++ -stdlib=libc++ t.cpp' to compile using it if installed. - In the future could also be used to select other standard library choices if alternatives become available (for example, to use an alternate C library). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113891 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-24Frontend: Add basic -H support.Daniel Dunbar

2010-08-24Driver/Clang: Forward -Wa, and -Xassembler to clang -cc1 when using theDaniel Dunbar
integrated assembler. For now this mostly just means that we will error out if someone tries to use this mechanism to send an argument to the assembler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111921 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-23Driver: Move Clang "triple" computation routines to method on theDaniel Dunbar
ToolChain. This fixes a potenial bad cast when running Clang on PPC code, since the tool chain in effect is not a subclass of the Darwin one, but we were treating it like it was. - This introduces some gross code duplication, but the right fix for it is to just move the Driver to start depending on the targets in libBasic, so I am not planning on fixing it immediately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111856 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-15Pass some things to the linker that gcc passes. -r is the only one of these ↵David Chisnall
that I'm sure about, but the others seem to be listed on FreeBSD by gcc -dumpspecs, so I hope they're right. Apparently -r is also not passed on GNU/Linux (and should be), but I can't see where the toolchain definition for this platform live. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111114 91177308-0d34-0410-b5e6-96231b3b80d8
