2014-04-28CodeGen: Fix linkage of reference temporariesDavid Majnemer1-2/+2
Summary: A reference temporary should inherit the linkage of the variable it initializes. Otherwise, we may hit cases where a reference temporary wouldn't have the same value in all translation units.

2014-01-14Remove the -cxx-abi command-line flag.Hans Wennborg1-1/+1
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

weak linkage. Also, fix a problem where global weak variables with non-trivial initializers were getting guard variables, or at least were checking for them and then crashing. llvm-svn: 129342
