2010-08-16Layout helper function.Matt Fleming
Introduce a helper method to add a section to the end of a layout. This will be used by the ELF ObjectWriter code to add the metadata sections (symbol table, etc) to the end of an object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111171 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-16Rename sat_shift operand to shift_imm, in preparation for using it for otherBob Wilson
instructions besides saturate instructions. No functional changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111168 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Partially revert r111155. It looks like MSVC is calling an operator<() thatJakob Stoklund Olesen
clang says is unused. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111167 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-16To create a copy of a SmallVector with an element removed from theDan Gohman
middle, copy the elements in two groups, rather than copying all the elements and then doing an erase on the middle of the result. These are SmallVectors, so we shouldn't expect to hit dynamic allocation in the common case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111151 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111143 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111142 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Move SCEVNAryExpr's virtual member functions out of line, and convertDan Gohman
them to iterators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111140 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111138 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Avoid gratuitous inefficiency in ifndef NDEBUG code.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Make one getAddExpr call when analyzing a+b+c+d+e+... instead of oneDan Gohman
for each add instruction. Ditto for Mul. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111136 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Delete an unused function.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111135 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Instead of having CollectSubexpr's categorize operands as interesting orDan Gohman
uninteresting, just put all the operands on one list and make GenerateReassociations make the decision about what's interesting. This is simpler, and it avoids an extra ScalarEvolution::getAddExpr call. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111133 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Put add operands in ScalarEvolution-canonical order, when convenient.Dan Gohman
This isn't necessary, because ScalarEvolution sorts them anyway, but it's tidier this way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111132 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Add hooks to FoldingSetTrait to allow specializations to provideDan Gohman
implementations of equality comparison and hash computation. This can be used to optimize node lookup by avoiding creating lots of temporary ID values just for hashing and comparison purposes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111130 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Reverse the order of GetNodeProfile's arguments, for consistencyDan Gohman
with FoldingSetTrait::Profile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111127 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Avoid #include <ScalarEvolution.h> in LoopSimplify.cpp, which doesn'tDan Gohman
actually use ScalarEvolution. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111124 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Instead, teach SimplifyCFG to trim non-address-taken blocks fromDan Gohman
indirectbr destination lists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111122 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-16Revert r111058, the lint check for indirectbr successors that aren'tDan Gohman
address-taken. This can occur normally, if the code which took the address got DCEd. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111121 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-15Revert r111082. No warnings for this common pattern.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111102 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-14Rework how the non-sse2 memory barrier is lowered so that theEric Christopher
encoding is correct for the built-in assembler. Based on a patch from Chris. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111083 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-14LoopSimplify shouldn't split loop backedges that use indirectbr. PR7867.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111061 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-14Teach SimplifyCFG how to simplify indirectbr instructions.Dan Gohman
- Eliminate redundant successors. - Convert an indirectbr with one successor into a direct branch. Also, generalize SimplifyCFG to be able to be run on a function entry block. It knows quite a few simplifications which are applicable to the entry block, and it only needs a few checks to avoid trouble with the entry block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111060 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-14Add a local stack object block allocation pass. This is still anJim Grosbach
experimental pass that allocates locals relative to one another before register allocation and then assigns them to actual stack slots as a block later in PEI. This will eventually allow targets with limited index offset range to allocate additional base registers (not just FP and SP) to more efficiently reference locals, as well as handle situations where locals cannot be referenced via SP or FP at all (dynamic stack realignment together with variable sized objects, for example). It's currently incomplete and almost certainly buggy. Work in progress. Disabled by default and gated via the -enable-local-stack-alloc command line option. rdar://8277890 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111059 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-13Add a Thumb2 t2RSBrr instruction for disassembly only.Bob Wilson
This fixes another part of PR7792. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111057 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-13Clean up the Spiller.h interface.Jakob Stoklund Olesen
The earliestStart argument is entirely specific to linear scan allocation, and can be easily calculated by RegAllocLinearScan. Replace std::vector with SmallVector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111055 91177308-0d34-0410-b5e6-96231b3b80d8
