2012-05-02Move llvm-tblgen's StringMatcher into the TableGen library so it canDouglas Gregor
be used by clang-tblgen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156000 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-25Add ifdef around getSubtargetFeatureName in tablegen output file so that ↵Craig Topper
only targets that want the function get it. This prevents other targets from getting an unused function warning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155538 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-24ARM: improved assembler diagnostics for missing CPU features.Jim Grosbach
When an instruction match is found, but the subtarget features it requires are not available (missing floating point unit, or thumb vs arm mode, for example), issue a diagnostic that identifies what the feature mismatch is. rdar://11257547 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155499 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-21Remove 'XXXRegisterClass' from tablegen output. Targets should use ↵Craig Topper
'&XXXRegClass' instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155270 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19TableGen support for auto-generating assembly two-operand aliases.Jim Grosbach
Assembly matchers for instructions with a two-operand form. ARM is full of these, for example: add {Rd}, Rn, Rm // Rd is optional and is the same as Rn if omitted. The property TwoOperandAliasConstraint on the instruction definition controls when, and if, an alias will be formed. No explicit InstAlias definitions are required. rdar://11255754 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155172 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-19Remove llvm-ld and llvm-stub (which is only used by llvm-ld).Michael J. Spencer
llvm-ld is no longer useful and causes confusion and so it is being removed. * Does not work very well on Windows because it must call a gcc like driver to assemble and link. * Has lots of hard coded paths which are wrong on many systems. * Does not understand most of ld's options. * Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} | ld, or fully replaced by Clang. I know of no production use of llvm-ld, and hacking use should be replaced by Clang's driver. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155147 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-19Use a SmallVector instead of std::vector for ResOperands.Jim Grosbach
There's almost always a small number of instruction operands, so use a SmallVector and save on heap allocations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155143 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-19Make fast isel use &XXXRegClass instead of XXXRegisterClass. Not a ↵Craig Topper
functional change since XXXRegisterClass is just a constant alias of &XXXRegClass, but should probably go away. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155104 91177308-0d34-0410-b5e6-96231b3b80d8

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
