2011-03-29Add intrinsics @llvm.arm.neon.vmulls and @llvm.arm.neon.vmullu.* back. FrontendsEvan Cheng
was lowering them to sext / uxt + mul instructions. Unfortunately the optimization passes may hoist the extensions out of the loop and separate them. When that happens, the long multiplication instructions can be broken into several scalar instructions, causing significant performance issue. Note the vmla and vmls intrinsics are not added back. Frontend will codegen them as intrinsics vmull* + add / sub. Also note the isel optimizations for catching mul + sext / zext are not changed either.

2011-03-29Fixed the build of Clang's unit tests on MinGW. Also removed someOscar Fuentes
unnecesary conditionals and introduced a new convenience function. The problem was that the list of libraries for Clang's unit tests was <clang libraries> <system libraries> <llvm libraries>. As the llvm libraries references symbols defined on the system libraries, those were reported as undefined. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128484 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-29Do some simple copy propagation through integer loads and stores when promotingCameron Zwarich
vector types. This helps a lot with inlined functions when using the ARM soft float ABI. Fixes <rdar://problem/9184212>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128453 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-29Properly enable rematerialization when spilling after live range splitting.Jakob Stoklund Olesen
The instruction to be rematerialized may not be the one defining the register that is being spilled. The traceSiblingValue() function sees through sibling copies to find the remat candidate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128449 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-28Again adding a C API to the disassembler for use by such tools as Darwin'sKevin Enderby
otool(1), this time with the needed fix for case sensitive file systems :) . This is a work in progress as the interface for producing symbolic operands is not done. But a hacked prototype using information from the object file's relocation entiries and replacing immediate operands with MCExpr's has been shown to work with no changes to the instrucion printer. These APIs will be moved into a dynamic library at some point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128415 91177308-0d34-0410-b5e6-96231b3b80d8
