Manman Ren	67effb97df	ARM ABI: fix ABI alignment issues in varargs. ... We generalize r166040 to handle ABI alignment issues for all types. rdar://12439123 llvm-svn: 166052	2012-10-16 19:51:48 +00:00
Manman Ren	fef9e3199a	ARM ABI: passing illegal vector types as varargs. ... We expand varargs in clang and the call site is handled in the back end, it is hard to match exactly how illegal vectors are handled in the backend. Therefore, we legalize the illegal vector types in clang: if (Size <= 32), legalize to i32. if (Size == 64), legalize to v2i32. if (Size == 128), legalize to v4i32. if (Size > 128), use indirect. rdar://12439123 llvm-svn: 166043	2012-10-16 19:18:39 +00:00
Manman Ren	cca54d0460	ARM ABI: fix ABI alignment issues when passing legal vector types as varargs. ... We create an aligned temporary space and copy the content over from ap.cur to the temporary space. This is necessary if the natural alignment of the type is greater than the ABI alignment. rdar://12439123 llvm-svn: 166040	2012-10-16 19:01:37 +00:00
