2010-12-10Formalize the notion that AVX and SSE are non-overlapping extensions from ↵Nate Begeman
the compiler's point of view. Per email discussion, we either want to always use VEX-prefixed instructions or never use them, and are taking "HasAVX" to mean "Always use VEX". Passing -mattr=-avx,+sse42 should serve to restore legacy SSE support when desirable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121439 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-14fix a nasty bug where we were not treating available_externallyChris Lattner

2010-04-02Separate out the AES-NI instructions from the SSE4.2 instructions. AddEric Christopher
a new subtarget option for AES and check for the support. Add "westmere" line of processors and add AES-NI support to the core i7. Add a couple of TODOs for information I couldn't verify. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100231 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-27Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it. Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94686 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-11Implement a feature (-vector-unaligned-mem) to allow targets toDavid Greene
ignore alignment requirements for SIMD memory operands. This is useful on architectures like the AMD 10h that do not trap on unaligned references if a status bit is twiddled at startup time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93151 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-22Remove target attribute break-sse-dep. Instead, do not fold load into sse ↵Evan Cheng
partial update instructions unless optimizing for size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91910 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-18On recent Intel u-arch's, folding loads into some unary SSE instructions canEvan Cheng
be non-optimal. To be precise, we should avoid folding loads if the instructions only update part of the destination register, and the non-updated part is not needed. e.g. cvtss2sd, sqrtss. Unfolding the load from these instructions breaks the partial register dependency and it can improve performance. e.g. movss (%rdi), %xmm0 cvtss2sd %xmm0, %xmm0 instead of cvtss2sd (%rdi), %xmm0 An alternative method to break dependency is to clear the register first. e.g. xorps %xmm0, %xmm0 cvtss2sd (%rdi), %xmm0 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91672 91177308-0d34-0410-b5e6-96231b3b80d8
