2011-09-28Rename SSEDomainFix -> lib/CodeGen/ExecutionDepsFix.Jakob Stoklund Olesen
I'll clean up the source in the next commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140663 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-27Remove X86-dependent stuff from SSEDomainFix.Jakob Stoklund Olesen
This also enables domain swizzling for AVX code which required a few trivial test changes. The pass will be moved to lib/CodeGen shortly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140659 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-27Promote the X86 Get/SetSSEDomain functions to TargetInstrInfo.Jakob Stoklund Olesen
I am going to unify the SSEDomainFix and NEONMoveFix passes into a single target independent pass. They are essentially doing the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140652 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-05Don't use PassInfo* as a type identifier for passes. Instead, use the ↵Owen Anderson
address of the static ID member as the sole unique type identifier. Clean up APIs related to this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110396 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-26Add StringRef::compare_numeric and use it to sort TableGen register records.Jakob Stoklund Olesen
This means that our Registers are now ordered R7, R8, R9, R10, R12, ... Not R1, R10, R11, R12, R2, R3, ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104745 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Eliminate MachineBasicBlock::const_livein_iterator and makeDan Gohman
MachineBasicBlock::livein_iterator a const_iterator, because clients shouldn't ever be using the iterator interface to mutate the livein set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101147 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-06Fix a number of clang -Wsign-compare warnings that didn't have an obviousJohn McCall
solution. The only reason these don't fire with gcc-4.2 is that gcc turns off part of -Wsign-compare in C++ on accident. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100581 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-06Don't try to collapse DomainValues onto an incompatible SSE domain.Jakob Stoklund Olesen
This fixes the Bullet regression on i386/nocona. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100553 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-04Clean up SSEDomainFix pass.Jakob Stoklund Olesen
Restrict bit mask operations to the DomainValue class. Rename methods for clarity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100353 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-31Fix PR6750. Don't try to merge a DomainValue with itself.Jakob Stoklund Olesen

2010-03-30Add cross-block inference to SSEDomainFix.Jakob Stoklund Olesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99916 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Be gentle to MSVC. C++ is hard, after all.Jakob Stoklund Olesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99855 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29Basic implementation of SSEDomainFix pass.Jakob Stoklund Olesen
Cross-block inference is primitive and wrong, but the pass is working otherwise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99848 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Fix -Asserts warning, again.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99542 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain ↵Jakob Stoklund Olesen
crossings. On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register in a different domain than where it was defined. Some instructions have equvivalents for different domains, like por/orps/orpd. The SSEDomainFix pass tries to minimize the number of domain crossings by changing between equvivalent opcodes where possible. This is a work in progress, in particular the pass doesn't do anything yet. SSE instructions are tagged with their execution domain in TableGen using the last two bits of TSFlags. Note that not all instructions are tagged correctly. Life just isn't that simple. The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline issue handled by NEONMoveFixPass. This pass may become target independent to handle both. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99524 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-23Revert "Add a late SSEDomainFix pass that twiddles SSE instructions to avoid ↵Jakob Stoklund Olesen
domain crossings." This reverts commit 99345. It was breaking buildbots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99352 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-23Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain ↵Jakob Stoklund Olesen
crossings. This is work in progress. So far, SSE execution domain tables are added to X86InstrInfo, and a skeleton pass is enabled with -sse-domain-fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99345 91177308-0d34-0410-b5e6-96231b3b80d8
