2004-04-25Fix file header comments and include guards -- many files have been moved orBrian Gaeke
renamed since they were last spiffed up, or they just never had proper comments in the first place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13148 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-25Add a getRegisterInfo() accessor just like on the X86 target.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13147 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-25Regularize file header comment and include guard.Brian Gaeke
Include SparcV9RegisterInfo.h. Add a getRegisterInfo() accessor and SparcV9RegisterInfo instance, just like on the X86 target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13146 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-25Add MRegisterInfo subclass for the SparcV9 target (containing only stubBrian Gaeke
functions for now). This automatically turns on the printing of machine registers using their own real names, instead of goofy things like %mreg(42), and allows us to migrate code incrementally to the new interface as we see fit. The register file description it uses is hand-written, so that the register numbers will match the ones that the SparcV9 target already uses. Perhaps someday we'll tablegen it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13145 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-23Move the scev expansion code into this pass, where it belongs. There isChris Lattner
still room for cleanup, but at least the code modification is out of the analysis now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13135 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Eliminate all of the SCEV Expansion code which is really part of theChris Lattner
IndVars pass, not part of SCEV *analysis*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13134 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13128 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Merge TargetRegInfo.h into SparcV9RegInfo.h, which is its only subclass.Brian Gaeke
This prepares us to be able to de-virtualize and de-abstract it, and take the register allocator bits out and move them into the register allocator proper... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13127 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Include SparcV9RegInfo.h instead of TargetRegInfo.h.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13126 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Include SparcV9RegInfo.h instead of TargetRegInfo.h. This serves as a bit ofBrian Gaeke
documentation that this module needs to be made independent of the register file description of the current target. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13125 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Get rid of the old byte-at-a-time emission code used when the Sparc JIT wasBrian Gaeke
being tested on X86, as per Chris's request. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13124 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Go back to the interpreter main loop after performing intrinsic lowering,Brian Gaeke
because 1) the first instruction might not be a call site, and 2) CS and SF.Caller were not getting set to point to the new call site anyway (resulting in a crash on e.g. call %llvm.memset). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13122 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23mmap of a zero length file returns null on some platforms, so hack around it.Brian Gaeke

2004-04-23Use emitWordAt() to emit forward-branch fixups.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13120 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Emit SPARC machine code a word at a time instead of a byte at a time.Brian Gaeke
Use emitWordAt() to emit forward-branch fixups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13119 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Implement emitWordAt() for the JIT emitter.Brian Gaeke
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13118 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Implement emitWordAt() for the debug emitter and the file printer emitter. (IBrian Gaeke
am not so sure about the file printer emitter, but the debug emitter change should be harmless.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13117 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-23Add emitWordAt() - a quick and dirty interface that the machine-dependentBrian Gaeke
emitters can use to emit "relocations". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13116 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Add command-line option to select whether to isolate or delete function fromMisha Brukman
module. Default is `isolate' as before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13113 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Clarify the logic: the flag is renamed to `deleteFn' to signify it will deleteMisha Brukman
the function instead of isolating it. This also means the condition is reversed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13112 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Add a flag to choose between isolating a function or deleting the function fromMisha Brukman
the Module. The default behavior keeps functionality as before: the chosen function is the one that remains. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13111 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Add a boolean flag to delete this function from module, leaving the rest behind.Misha Brukman
Useful in manual debugging when bugpoint isn't quite up to snuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13110 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Add a space before result for readability on the command line.Misha Brukman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13109 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Disable a previous patch that was causing indvars to loop infinitely :(Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13108 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13107 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Fix an extremely serious thinko I made in revision 1.60 of this file.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13106 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-22Add a methodChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13105 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-21Implement a todo, rewriting all possible scev expressions inside of theChris Lattner
loop. This eliminates the extra add from the previous case, but it's not clear that this will be a performance win overall. Tommorows test results will tell. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13103 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-21This code really wants to iterate over the OPERANDS of an instruction, notChris Lattner
over its USES. If it's dead it doesn't have any uses! :) Thanks to the fabulous and mysterious Bill Wendling for pointing this out. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13102 91177308-0d34-0410-b5e6-96231b3b80d8
2004-04-21Implement a fixme. The helps loops that have induction variables of differentChris Lattner
types in them. Instead of creating an induction variable for all types, it creates a single induction variable and casts to the other sizes. This generates this code: no_exit: ; preds = %entry, %no_exit %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=4] *** %j.0.0 = cast uint %indvar to short ; <short> [#uses=1] %indvar = cast uint %indvar to int ; <int> [#uses=1] %tmp.7 = getelementptr short* %P, uint %indvar ; <short*> [#uses=1] store short %j.0.0, short* %tmp.7 %inc.0 = add int %indvar, 1 ; <int> [#uses=2] %tmp.2 = setlt int %inc.0, %N ; <bool> [#uses=1] %indvar.next = add uint %indvar, 1 ; <uint> [#uses=1] br bool %tmp.2, label %no_exit, label %loopexit instead of: no_exit: ; preds = %entry, %no_exit %indvar = phi ushort [ %indvar.next, %no_exit ], [ 0, %entry ] ; <ushort> [#uses=2] *** %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=3] %indvar = cast uint %indvar to int ; <int> [#uses=1] %indvar = cast ushort %indvar to short ; <short> [#uses=1] %tmp.7 = getelementptr short* %P, uint %indvar ; <short*> [#uses=1] store short %indvar, short* %tmp.7 %inc.0 = add int %indvar, 1 ; <int> [#uses=2] %tmp.2 = setlt int %inc.0, %N ; <bool> [#uses=1] %indvar.next = add uint %indvar, 1 *** %indvar.next = add ushort %indvar, 1 br bool %tmp.2, label %no_exit, label %loopexit This is an improvement in register pressure, but probably doesn't happen that often. The more important fix will be to get rid of the redundant add. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13101 91177308-0d34-0410-b5e6-96231b3b80d8
