2011-07-08Revert x86_64 ABI changes until I have time to check the items raised by Eli.Bruno Cardoso Lopes

2011-07-02Don't use x86_mmx where it isn't necessary.Eli Friedman
The start of some work on getting -mno-mmx working the way we want it to. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134300 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-29We don't pass classes with a copy-constructor or destructor byval, so the ↵Eli Friedman
address takes up an integer register (if one is available). Make sure the x86-64 ABI implementation takes that into account properly. The fixed implementation is compatible with the implementation both gcc and llvm-gcc use. rdar://9686430 . (This is the issue that was reported in the thread "[LLVMdev] Segfault calling LLVM libs from a clang-compiled executable".) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134059 91177308-0d34-0410-b5e6-96231b3b80d8

Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions.

2011-05-22make the x86-32 backend specify a byval alignment, even when theChris Lattner
code generator will do it. With this patch, clang compiles the example in PR9794 to not have an alloca temporary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@131881 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-22Fix x86-64 byval passing to specify the alignment even when the codeChris Lattner
