2012-10-09When we load a function or method body from an AST file, we checkDouglas Gregor
whether that function/method already has a body (loaded from some other AST file), as introduced in r165137. Delay this check until after the redeclaration chains have been wired up. While I'm here, make the loading of method bodies lazy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165513 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-09If a macro has been #undef'd in a precompiled header, we still need toDouglas Gregor
write out the macro history for that macro. Similarly, we need to cope with reading a macro definition that has been #undef'd. Take advantage of this new ability so that global code-completion results can refer to #undef'd macros, rather than losing them entirely. For multiply defined/#undef'd macros, we will still get the wrong result, but it's better than getting no result. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165502 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-06Expose __builtin_bswap16.Benjamin Kramer
GCC has always supported this on PowerPC and 4.8 supports it on all platforms, so it's a good idea to expose it in clang too. LLVM supports this on all targets. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165362 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-05Implement -Wshift-op-parentheses for: a << b + cDavid Blaikie
This appears to be consistent with GCC's implementation of the same warning under -Wparentheses. Suppressing a << b + c for cases where 'a' is a user defined type for compatibility with C++ stream IO. Otherwise suggest parentheses around the addition or subtraction subexpression. (this came up when MSVC was complaining (incorrectly, so far as I can tell) about a perceived violation of this within the LLVM codebase, PR14001) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165283 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-04Driver: Link crtfastmath.o if it's available and -ffast-math is specified.Benjamin Kramer
crtfastmath.o contains routines to set the floating point flags to a faster, unsafe mode. Linking it in speeds up code dealing with denormals significantly (PR14024). For now this is only enabled on linux where I can test it and crtfastmath.o is widely available. We may want to provide a similar file with compiler-rt eventually and/or enable it on other platforms too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165240 91177308-0d34-0410-b5e6-96231b3b80d8
