2011-12-19Remove the restriction on the first operand of the add node in SelectAddr.Akira Hatanaka
This change reduces the number of instructions generated. For example, (load (add (sub $n0, $n1), (MipsLo got(s)))) results in the following sequence of instructions: 1. sub $n2, $n0, $n1 2. lw got(s)($n2) Previously, three instructions were needed. 1. sub $n2, $n0, $n1 2. addiu $n3, $n2, got(s) 3. lw 0($n3) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146888 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-19ARM NEON relax parse time diagnostics for alignment specifiers.Jim Grosbach
There's more variation that we need to handle. Error checking will need to be on operand predicates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146884 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-19Remove a register class that can just as well be synthesized.Jakob Stoklund Olesen
Add the new TableGen register class synthesizer feature to the release notes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146875 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-19Handle sub-register operands in recomputeRegClass().Jakob Stoklund Olesen
Now that getMatchingSuperRegClass() returns accurate results, it can be used to compute constraints imposed by instructions using a sub-register of a virtual register. This means we can recompute the register class of any virtual register by combining the constraints from all its uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146874 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-19Emit a getMatchingSuperRegClass() implementation for every target.Jakob Stoklund Olesen
Use information computed while inferring new register classes to emit accurate, table-driven implementations of getMatchingSuperRegClass(). Delete the old manual, error-prone implementations in the targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146873 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-19Synthesize register classes for TRI::getMatchingSuperRegClass().Jakob Stoklund Olesen
Teach TableGen to create the missing register classes needed for getMatchingSuperRegClass() to return maximal results. The function is still not auto-generated, so it still returns inexact results. This produces these new register classes: ARM: QQPR_with_dsub_0_in_DPR_8 QQQQPR_with_dsub_0_in_DPR_8 X86: GR64_with_sub_32bit_in_GR32_NOAX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOSP GR64_with_sub_16bit_in_GR16_NOREX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOREX GR64_TC_and_GR64_with_sub_32bit_in_GR32_NOAX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOREX_NOSP GR64_TCW64_and_GR64_with_sub_32bit_in_GR32_NOAX GR64_TC_and_GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_NOREX GR64_with_sub_32bit_in_GR32_TC GR64_with_sub_32bit_in_GR32_ABCD_and_GR32_NOAX GR64_with_sub_32bit_in_GR32_NOAX_and_GR32_TC GR64_with_sub_32bit_in_GR32_AD GR64_with_sub_32bit_in_GR32_AD_and_GR32_NOAX The other targets in the tree are not weird enough to be affected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146872 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146846 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-17Revert 146728 as it's causing failures on some of the external bots as well as Chad Rosier
internal nightly testers. Original commit message: By popular demand, link up types by name if they are isomorphic and one is an autorenamed version of the other. This makes the IR easier to read, because we don't end up with random renamed versions of the types after LTO'ing a large app. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146838 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-17As Doug pointed out (and I really should know), it is perfectly easy toChandler Carruth
make VariadicFunction actually be trivial. Do so, and also make it look more like your standard trivial functor by making it a struct with no access specifiers.

2011-12-16Don't adjust for alignment padding in OffsetIsInRange.Jakob Stoklund Olesen
This adjustment is already included in the block offsets computed by BasicBlockInfo, and adjusting again here can cause the pass to loop. When CreateNewWater splits a basic block, OffsetIsInRange would reject the new CPE on the next pass because of the too conservative alignment adjustment. This caused the block to be split again, and so on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146751 91177308-0d34-0410-b5e6-96231b3b80d8
