Simplify CMake rules in HandleLLVMOptions module.

Summary: No functionality change. Reviewers: Bigcheese Reviewed By: Bigcheese CC: llvm-commits Differential Revision: http://llvm-reviews.chandlerc.com/D535 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176973 91177308-0d34-0410-b5e6-96231b3b80d8

CMake: Always include the CheckCXXCompilerFlag in HandleLLVMOptions.cmake.

Previously we relied on it being included by config-ix.cmake. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176396 91177308-0d34-0410-b5e6-96231b3b80d8

Use correct host/target CMake variables to define lit variables.

2013-02-14T16:49:32Z

CMake and autotools disagree on what "host" means in a cross-compilation context. Autotools (and lit) take it to be the machine the binaries being compiled now will run on. CMake takes it to be the machine actually compiling the binaries now. This change makes lit.site-cfg more consistent between autotools and CMake, allowing lit tests (particularly in ExecutionEngine) to run correctly when cross-compiled with CMake git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175179 91177308-0d34-0410-b5e6-96231b3b80d8

CMake: Use check_symbol_exists instead of check_cxx_symbol_exists.

2013-02-08T23:17:31Z

check_cxx_symbol_exists requires CMake 2.8.6, so even though I recommended it to Owen it's probably better to stay away for now. This check is not technically correct because we're checking but then using in the actual code, but if we run into problems we can do the same sort of dance as isinf() and isnan() where we check /both/ headers and then write a wrapper header around them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174773 91177308-0d34-0410-b5e6-96231b3b80d8

Fix CMake detection of various cmath functions, and XFAIL the test on platforms that are known to be missing them.

Conditionalize constant folding of math intrinsics on the availability of an implementation on the host. This is a little bit unfortunate, but until someone decides to implement a full libm for APFloat, we don't have a better way to get this functionality.

Turn off uninitialized-use warnings for gcc in cmake build

2013-02-04T02:32:44Z

Added support to the cmake build to turn off uninitialized use warnings for gcc. This cleans the build up somewhat. Used logic simpler than found in autoconf by making use of the fact that although gcc won't complain about unsupported -Wno-* flags it *will* complain about unsupported -W flags.

Add -Wno-nested-anon-types to -pedantic builds of LLVM. This Clang warning

2013-01-31T22:19:12Z

catches uses of an extremely minor and widely-available C++ extension (which every C++ compiler I could find supports, but EDG and Clang reject in strict mode). The diagnosed code pattern looks like this: struct X { union { struct { int a; int b; } S; }; }; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174103 91177308-0d34-0410-b5e6-96231b3b80d8
