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

2010-08-24Frontend: Add basic -H support.Daniel Dunbar
- I didn't implement the GCC "multiple include guard" detection parts, because it doesn't seem useful or obvious. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111983 91177308-0d34-0410-b5e6-96231b3b80d8
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

2010-06-26Implement support for -fwrapv, rdar://7221421Chris Lattner
As part of this, pull together trapv handling into the same enum. This also add support for NSW multiplies. This also makes PCH disagreement on overflow behavior silent, since it really doesn't matter except for warnings and codegen (no macros get defined etc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106956 91177308-0d34-0410-b5e6-96231b3b80d8
