2004-05-01Iterate over the Machine CFG that Brian added instead of the LLVM CFG.Chris Lattner
Look at all of the pretty minuses. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13303 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-01Operate on the Machine CFG instead of on the LLVM CFGChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13302 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-01Stop LiveVariables from using BasicBlocks as part of the mapping, insteadChris Lattner
use MachineBasicBlocks. To do this, we traverse the Machine CFG instead of the LLVM CFG, which is also *MUCH* more efficient by having fewer levels of indirections and mappings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13301 91177308-0d34-0410-b5e6-96231b3b80d8

2004-04-30Fix a major pessimization in the instcombiner. If an allocation instructionChris Lattner
is only used by a cast, and the casted type is the same size as the original allocation, it would eliminate the cast by folding it into the allocation. Unfortunately, it was placing the new allocation instruction right before the cast, which could pull (for example) alloca instructions into the body of a function. This turns statically allocatable allocas into expensive dynamically allocated allocas, which is bad bad bad. This fixes the problem by placing the new allocation instruction at the same place the old one was, duh. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13289 91177308-0d34-0410-b5e6-96231b3b80d8

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

2004-04-23Merge 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

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

2004-04-23Go 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

2004-04-23Implement 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
2004-04-22Clarify 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
