2012-05-26Change warning to error when property setter names conflict.Fariborz Jahanian
// rdar://11528439 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157517 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-26In response to some discussions on IRC, tweak the wording of the newRichard Smith
-Wsometimes-uninitialized diagnostics to make it clearer that the cause of the issue may be a condition which must always evaluate to true or false, rather than an uninitialized variable. To emphasize this, add a new note with a fixit which removes the impossible condition or replaces it with a constant. Also, downgrade the diagnostic from -Wsometimes-uninitialized to -Wconditional-uninitialized when it applies to a range-based for loop, since the condition is not written explicitly in the code in that case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157511 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-25Split a chunk of -Wconditional-uninitialized warnings out into a separate flag,Richard Smith
-Wsometimes-uninitialized. This detects cases where an explicitly-written branch inevitably leads to an uninitialized variable use (so either the branch is dead code or there is an uninitialized use bug). This chunk of warnings tentatively lives within -Wuninitialized, in order to give it more visibility to existing Clang users. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157458 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-24Add a warning to diagnose statements in C++ like "*(volatile int*)x;". ↵Eli Friedman
Conceptually, this is part of -Wunused-value, but I added a separate flag -Wunused-volatile-lvalue so it doesn't get turned off by accident with -Wno-unused-value. I also made a few minor improvements to existing unused value warnings in the process. <rdar://problem/11516811>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157362 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-20CUDA: add CodeGen support for global variable address spaces.Peter Collingbourne
Because in CUDA types do not have associated address spaces, globals are declared in their "native" address space, and accessed by bitcasting the pointer to address space 0. This relies on address space 0 being a unified address space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157167 91177308-0d34-0410-b5e6-96231b3b80d8
