Remove the -cxx-abi command-line flag. 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.

Fix for PR5707: make sure implicit copy constructors initialize the vtable pointer. llvm-svn: 90840 2009-12-08 14:46:18 +08:00

Restore r184205 and associated commits (after commit of r185290) This allows clang to use the backend parameter attribute 'returned' when generating 'this'-returning constructors and destructors in ARM and MSVC C++ ABIs. llvm-svn: 185291 2013-07-01 04:40:16 +08:00			`// CHECK: define linkonce_odr {{.}} @_ZN1AC1ERKS_(%struct.A {{.}}%this, %struct.A) unnamed_addr`
Partially revert r184225 test changes and make a smaller and more generic fix. llvm-svn: 184232 2013-06-19 04:51:51 +08:00			`// CHECK: store i8** getelementptr inbounds ([3 x i8] @_ZTV1A, i64 0, i64 2)`
