* Refactor and check "onlyReadsMemory" before optimizing builtins.Bob Wilson2012-08-03
| | | | | | | | | This patch is mostly just refactoring a bunch of copy-and-pasted code, but it also adds a check that the call instructions are readnone or readonly. That check was already present for sin, cos, sqrt, log2, and exp2 calls, but it was missing for the rest of the builtins being handled in this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161282 91177308-0d34-0410-b5e6-96231b3b80d8
* TwoAddressInstructionPass refactoring: Extract a method.Jakob Stoklund Olesen2012-08-03
| | | | | | | No functional change intended, except replacing a DenseMap with a SmallDenseMap which should behave identically. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161281 91177308-0d34-0410-b5e6-96231b3b80d8
* Begin adding support for updating LiveIntervals in TwoAddressInstructionPass.Jakob Stoklund Olesen2012-08-03
| | | | | | | This is far from complete, and only changes behavior when the -early-live-intervals flag is passed to llc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161273 91177308-0d34-0410-b5e6-96231b3b80d8
* 1. Redo mips16 instructions to avoid multiple opcodes for same instruction.Akira Hatanaka2012-08-03
| | | | | | | | | | | Change these to patterns. 2. Add another 16 instructions. Patch by Reed Kotler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161272 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an experimental -early-live-intervals option.Jakob Stoklund Olesen2012-08-03
| | | | | | | | | | This option runs LiveIntervals before TwoAddressInstructionPass which will eventually learn to exploit and update the analysis. Eventually, LiveIntervals will run before PHIElimination, and we can get rid of LiveVariables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161270 91177308-0d34-0410-b5e6-96231b3b80d8
* Delete merged physreg copies in joinReservedPhysReg().Jakob Stoklund Olesen2012-08-03
| | | | | | | Previously, the identity copy would survive through register allocation before it was removed by the rewriter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161269 91177308-0d34-0410-b5e6-96231b3b80d8
* Try to reduce the compile time impact of r161232.Bob Wilson2012-08-03
| | | | | | | | | | | | The previous change caused fast isel to not attempt handling any calls to builtin functions. That included things like "printf" and caused some noticable regressions in compile time. I wanted to avoid having fast isel keep a separate list of functions that had to be kept in sync with what the code in SelectionDAGBuilder.cpp was handling. I've resolved that here by moving the list into TargetLibraryInfo. This is somewhat redundant in SelectionDAGBuilder but it will ensure that we keep things consistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161263 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix memcmp code-gen to honor -fno-builtin.Bob Wilson2012-08-03
| | | | | | | | | I noticed that SelectionDAGBuilder::visitCall was missing a check for memcmp in TargetLibraryInfo, so that it would use custom code for memcmp calls even with -fno-builtin. I also had to add a new -disable-simplify-libcalls option to llc so that I could write a test for this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161262 91177308-0d34-0410-b5e6-96231b3b80d8
* Completely eliminate VNInfo flags.Jakob Stoklund Olesen2012-08-03
| | | | | | | | The 'unused' state of a value number can be represented as an invalid def SlotIndex. This also exposed code that shouldn't have been looking at unused value VNInfos. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161258 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix a couple of loops that were processing unused value numbers.Jakob Stoklund Olesen2012-08-03
| | | | | | | Unused VNInfos should be left alone. Their def SlotIndex doesn't point to anything. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161257 91177308-0d34-0410-b5e6-96231b3b80d8

* Eliminate the VNInfo::hasPHIKill() flag.Jakob Stoklund Olesen2012-08-03
| | | | | | | | | | The only real user of the flag was removeCopyByCommutingDef(), and it has been switched to LiveIntervals::hasPHIKill(). All the code changed by this patch was only concerned with computing and propagating the flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161255 91177308-0d34-0410-b5e6-96231b3b80d8
* Make the hasPHIKills flag a computed property.Jakob Stoklund Olesen2012-08-03
| | | | | | | | | | | | | The VNInfo::HAS_PHI_KILL is only half supported. We precompute it in LiveIntervalAnalysis, but it isn't properly updated by live range splitting and functions like shrinkToUses(). It is only used in one place: RegisterCoalescer::removeCopyByCommutingDef(). This patch changes that function to use a new LiveIntervals::hasPHIKill() function that computes the flag for a given value number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161254 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a BUILD_FLAGS variable so that autoconf checks have a placeEric Christopher2012-08-03

This should enable us to remove the AC_SUBSTs in the intel checks, but I have no way of testing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161233 91177308-0d34-0410-b5e6-96231b3b80d8
* Fall back to selection DAG isel for calls to builtin functions.Bob Wilson2012-08-03
| | | | | | | | | | Fast isel doesn't currently have support for translating builtin function calls to target instructions. For embedded environments where the library functions are not available, this is a matter of correctness and not just optimization. Most of this patch is just arranging to make the TargetLibraryInfo available in fast isel. <rdar://problem/12008746> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161232 91177308-0d34-0410-b5e6-96231b3b80d8

* Move the "findUsedStructTypes" functionality outside of the Module class.Bill Wendling2012-08-03
| | | | | | | | | | The "findUsedStructTypes" method is very expensive to run. It needs to be optimized so that LTO can run faster. Splitting this method out of the Module class will help this occur. For instance, it can keep a list of seen objects so that it doesn't process them over and over again. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161228 91177308-0d34-0410-b5e6-96231b3b80d8
