git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23363 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-14Promote xform fns to be explicit nodes in result patterns, and clean offChris Lattner
predicates since they will have already matched at this point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23362 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-14start building the instruction dest pattern correctly. Change the xformChris Lattner
functions to preserve the Record for the xform instead of making it into a function name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23361 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23357 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-14Check that operands have unique names. REJECT instructions with broken operandChris Lattner
lists: only don't parse them if they are entirely missing (sparcv9). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23355 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-14Parse significantly more of the instruction pattern, now collecting andChris Lattner
verifying information about the operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23353 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-14Fix some issues exposed by more testing. XORIS had the wrong operandsChris Lattner
specified. The various *imm operands defined by PPC are really all i32, even though the actual immediate is restricted to a smaller value in it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23352 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-13Emit code suitable for emission into the ISel class, allowing us to use/defineChris Lattner
methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23340 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-13Add a new Record::getValueAsCode method to mirror the other getValueAs*Chris Lattner
methods. Use it to simplify some code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23336 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-13Change the arg lowering code to use copyfromreg from vregs associatedChris Lattner
with incoming arguments instead of the pregs themselves. This fixes the scheduler from causing problems by moving a copyfromreg for an argument to after a select_cc node (now it can, and bad things won't happen). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23334 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-13If a function has liveins, and if the target requested that they be ploppedChris Lattner
into particular vregs, emit copies into the entry MBB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23331 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-13Add a simple xform to simplify array accesses with casts in the way.Chris Lattner
This is useful for 178.galgel where resolution of dope vectors (by the optimizer) causes the scales to become apparent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23328 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-13Fix an issue where LSR would miss rewriting a use of an IV expression by a ↵Chris Lattner
PHI node that is not the original PHI. This fixes up a dot-product loop in galgel, speeding it up from 18.47s to 16.13s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23327 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-13Add a helper function, allowing us to simplify some code a bit, changingChris Lattner
indentation, no functionality change git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23325 91177308-0d34-0410-b5e6-96231b3b80d8
2005-09-12Implement a simple xform to turn code like this:Chris Lattner
if () { store A -> P; } else { store B -> P; } into a PHI node with one store, in the most trival case. This implements load.ll:test10. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23324 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-12Another load-peephole optimization: do gcse when two loads are next toChris Lattner
each other. This implements InstCombine/load.ll:test9 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23322 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-12Implement a trivial form of store->load forwarding where the store and theChris Lattner
load are exactly consequtive. This is picked up by other passes, but this triggers thousands of times in fortran programs that use static locals (and is thus a compile-time speedup). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23320 91177308-0d34-0410-b5e6-96231b3b80d8

2005-09-12Fix a regression from last night, which caused this pass to create invalidChris Lattner
code for IV uses outside of loops that are not dominated by the latch block. We should only convert these uses to use the post-inc value if they ARE dominated by the latch block. Also use a new LoopInfo method to simplify some code.
