* When performing a ::delete of an object with a virtual destructor,John McCall2012-09-254-1/+50
| | | | | | | | | | | | | | be sure to delete the complete object pointer, not the original pointer. This is necessary if the base being deleted is at a non-zero offset in the complete object. This is only required for objects with virtual destructors because deleting an object via a base-class subobject when the base does not have a virtual destructor is undefined behavior. Noticed while reviewing the last four years of cxx-abi-dev activity. llvm-svn: 164597

| | | | | | | | | | | | into the enclosing scope; this is a more accurate model but is (I believe) unnecessary in my test case due to other flaws. However, one of those flaws is now intentional: blocks which appear in return statements can be trivially observed to not extend in lifetime past the return, and so we can allow a jump past them. Do the necessary magic in IR-generation to make this work. llvm-svn: 164589

* ARM: Use a dedicated intrinsic for vector bitwise select.Jim Grosbach2012-09-211-0/+4
| | | | | | | | | | | The expression based expansion too often results in IR level optimizations splitting the intermediate values into separate basic blocks, preventing the formation of the VBSL instruction as the code author intended. In particular, LICM would often hoist part of the computation out of a loop. rdar://11011471 llvm-svn: 164342

* Use custom ABIInfo for le32/PNaCl argument codegenDerek Schuff2012-09-061-0/+86
| | | | | | | | | This patch uses a new ABIInfo implementation specific to the le32 target, rather than falling back to DefaultABIInfo. Its behavior is basically the same, but it also allows the regparm argument attribute. It also includes basic tests for argument codegen and attributes. llvm-svn: 163333

* Rename ANDROIDEABI to Android.Logan Chien2012-09-021-1/+2
| | | | | | | | | | | | | Most of the code guarded with ANDROIDEABI are not ARM-specific, and having no relation with arm-eabi. Thus, it will be more natural to call this environment "Android" instead of "ANDROIDEABI". Note: We are not using ANDROID because several projects are using "-DANDROID" as the conditional compilation flag. llvm-svn: 163088
