git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82925 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27allow pushing icmps through phis with multiple uses and across critical edges.Chris Lattner
These are important to push up to encourage jump threading. This shrinks 176.gcc a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82923 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Enhance the previous fix for PR4895 to allow more values than justChris Lattner
simple constants for the true/false value of the select. We now do phi translation etc. This really fixes PR4895 :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82917 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27implement PR4895, by making FoldOpIntoPhi handle select conditionsChris Lattner
that are phi nodes. Also tighten up FoldOpIntoPhi to treat constantexpr operands to phis just like other variables, avoiding moving constantexpr computations around. Patch by Daniel Dunbar. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82913 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27avoid copying MCAsmInfo by value, add an (extremely low prio) fixme.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82911 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Use explicit structs instead of std::pair to map callee saved regs to spill ↵Tilmann Scheller
slots. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82909 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Delete a bogus comment.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82908 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Remove a redundant assert.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82907 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Enable -g with DEBUG_SYMBOLS and --enable-debug-symbols instead ofJeffrey Yasskin
DEBUG_RUNTIME. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82906 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Fix SCEVExpander's canonical addrec expansion code to work on loops thatDan Gohman
aren't in canonical loop-simplify form, since it doesn't itself depend on LoopSimplify. This means handling loops without preheaders and loops with multiple backedges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82905 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Add dominates and releaseMemory member functions to PostDominatorTree.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82904 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Grab an LLVM Context from an instruction that exists rather than oneDan Gohman
that is deleted in some situations. This fixes a use-after-free. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82903 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Clarify a comment.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82902 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Tell ScalarEvolution to forget everything it knows about a loop beforeDan Gohman
rotating the loop, since loop rotation is a very significant change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82901 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Micro-optimize DerivedType::dropAllTypeUses.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82900 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Instead of testing whether an instruction dominates the loop preheader,Dan Gohman
test whether it properly dominates the loop header. This is equivalent when the loop has a preheader, and has the advantage of working when the loop doesn't have a preheader. Since IVUsers doesn't Require LoopSimplify, the loop isn't guaranteed to have a preheader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82899 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Add a properlyDominates member function to ScalarEvolution.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82898 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Remove a redundant #include.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82897 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Avoid using mutex locks if not in multithreaded mode by using a SmartScopedMutexTorok Edwin
in RegisterStatistic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82896 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Enable pre-regalloc load / store multiple pass for Thumb2.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82893 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27rename REG -> REGISTER to make it explicit in the doc. <tt>ify some stuff.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82892 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27implement and document support for filecheck variables. ThisChris Lattner
allows matching and remembering a string and then matching and verifying that the string occurs later in the file. Change X86/xor.ll to use this in some cases where the test was checking for an arbitrary register allocation decision. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82891 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Remove dead code from this function and optimize. Update its correspondingNick Lewycky
LangRef entry too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82890 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Instruction::clone does not need to take an LLVMContext&. Remove that andNick Lewycky
update all the callers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82889 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Filecheckify this one test.Nick Lewycky
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82888 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Leave a pointer to the documentation so that people don't end up change one butNick Lewycky
not the other in the future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82887 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Correct the version numbers to match those actually tested for byNick Lewycky
autoconf/AutoRegen.sh. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82886 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-27Move the integer type out of 'derived' and into 'primitive'. This permits usNick Lewycky
to explain that derived types are all composed of other types, which primitive types aren't. Without moving integer out of derived, this wouldn't be true. Perform a few trivial cleanups; 'i1' went from a link to #t_primitive to #t_integer (a holdover from when it was a bool type I suppose). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82884 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26remove support for "NoSub" from regex. It seems like a minor optimizationChris Lattner
and makes the API more annoying. Add a Regex::getNumMatches() method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82877 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26Speed up clang-only link, by really linking only clang, and not the unittestsTorok Edwin
too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82873 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82869 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26Fix SimplifyLibCalls to transfer attributes from callees rather thanDan Gohman
calls, since direct calls don't always reflect the attributes of their callees. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82867 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26Fix a case where ScalarEvolution was expanding pointer arithmeticDan Gohman
to inttoptr/ptrtoint unnecessarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82864 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26For the NSWSub support in the builder to actually be useable,Duncan Sands
there need to be corresponding changes to the constant folders, done in this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82862 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26Convert comparisons like (x == infinity) to (x >= infinity) on targetsDan Gohman
where FCMP_OEQ is not legal and FCMP_OGE is, such as x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82861 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26Add methods for creating NSW subtraction, as already existsDuncan Sands
for addition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82860 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82859 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-26"Update" tests for -disable-if-conversion removal. I think branch.ll should justDaniel Dunbar
be removed, but I XFAIL'd it for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82847 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-26Don't hoist or sink instructions with physreg uses if the physreg isDan Gohman

typically faster then doing a general pow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82819 91177308-0d34-0410-b5e6-96231b3b80d8
