2012-04-18Revert "Replace some uses of std:map<std::string,...> with StringMap."Jim Grosbach
StringMap iterators are not deterministic, and that's more important here than speed or memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155039 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-11TableGen'd regpressure: register unit set pruning.Andrew Trick
The pruning is more complete if it is not done incrementally. The code is also a tad less convluted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154510 91177308-0d34-0410-b5e6-96231b3b80d8

Jakob's review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154377 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-10Added register unit sets to the target description.Andrew Trick
This is a new algorithm that finds sets of register units that can be used to model registers pressure. This handles arbitrary, overlapping register classes. Each register class is associated with a (small) list of pressure sets. These are the dimensions of pressure affected by the register class's liveness. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154374 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-10Added register unit weights to the target description.Andrew Trick
This is a new algorithm that associates registers with weighted register units to accuretely model their effect on register pressure. This handles registers with multiple overlapping subregisters. It is possible, but almost inconceivable that the algorithm fails to find an exact solution for a target description. If an exact solution cannot be found, an inexact, but reasonable solution will be chosen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154373 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-02Emit the asm writer's mnemonic table with SequenceToOffsetTable.Benjamin Kramer
This way we can get AVX v-prefixed instructions tail merged with the normal insns. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153869 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-02Reorder fields in MatchEntry and OperandMatchEntry to reduce padding. A bit ↵Craig Topper
tricky due to the target specific sizes for some of the fields so the ordering is only optimal for the targets in the tree. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153865 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-02Remove getInstructionName from MCInstPrinter implementations in favor of ↵Craig Topper

2012-04-02Use SequenceToOffsetTable to generate instruction name table for AsmWriter.Craig Topper
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153857 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-01Use SequenceToOffsetTable to create instruction name table. Saves space ↵Craig Topper
particularly on X86 where AVX instructions just add a 'v' to the front of other instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153841 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-01Emit the LLVM<->DWARF register mapping as a sorted table and use binary ↵Benjamin Kramer
search to do the lookup. This also avoids emitting the information twice, which led to code bloat. On i386-linux-Release+Asserts with all targets built this change shaves a whopping 1.3 MB off clang. The number is probably exaggerated by recent inliner changes but the methods were already enormous with the old inline cost computation. The DWARF reg -> LLVM reg mapping doesn't seem to have holes in it, so it could be a simple lookup table. I didn't implement that optimization yet to avoid potentially changing functionality. There is still some duplication both in tablegen and the generated code that should be cleaned up eventually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153837 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-31Introduce Register Units: Give each leaf register a number.Andrew Trick
First small step toward modeling multi-register multi-pressure. In the future, register units can also be used to model liveness and aliasing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153794 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30Use SequenceToOffsetTable in emitRegisterNameString.Jakob Stoklund Olesen
This allows suffix sharing in register names. (AX is a suffix of EAX). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153777 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-30Reapply 153764 and 153761 with a fix.Jakob Stoklund Olesen
Use an explicit comparator instead of the default. The sets are sorted, but not using the default comparator. Hopefully, this will unbreak the Linux builders. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153772 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-30Compress register lists by sharing suffixes.Jakob Stoklund Olesen
TableGen emits lists of sub-registers, super-registers, and overlaps. Put them all in a single table and use a SequenceToOffsetTable to share suffixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153761 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-30Add a SequenceToOffsetTable to TableGen.Jakob Stoklund Olesen
This is similar to the StringToOffsetTable we use to produce string tables, but it can be used for other sequences than strings, and it eliminates entries for suffixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153760 91177308-0d34-0410-b5e6-96231b3b80d8
