2003-08-12For an instruction with delay slots, mark all live values beforeVikram S. Adve
the instruction as being live before/after the delay slot instructions as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7795 91177308-0d34-0410-b5e6-96231b3b80d8
2003-08-12Give std::map<BasicBlock *, BasicBlock *> the short name BBMap, becauseBrian Gaeke
it's used 7 different times. Rename `getBackEdges' to `findAndInstrumentBackEdges', for clarity. Remove some excess whitespace and commented-out code. Use shorter forms of CallInst ctors. Do not make `reopt_threshold' visible to the LLVM program, and do not pass it to the call to `reoptimizerInitialize'. Don't pass the GlobalVariable representing it to any of our helper methods. `reopt_threshold' is an internal parameter of the reoptimizer, which InstLoops does not need to know about. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7794 91177308-0d34-0410-b5e6-96231b3b80d8

2003-08-07Fixed a segfault in gccld.John Criswell
The original code does not work because the value from WorkList.end() is invalidated once WorkList.erase() is called. To ensure proper functionality, we must ensure that WorkList.erase() is always called before WorkList.end(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7673 91177308-0d34-0410-b5e6-96231b3b80d8

2003-08-06Use the registers g1 and g5 as temporaries for making far jumps and far calls,Misha Brukman
because saving i1 and i2 to their ``designated'' stack slots corrupts unknown memory in other functions, standard libraries, and worse. In addition, this has the benefit of improving JIT performance because we eliminate writing out 4 instructions in CompilationCallback() and 2 loads and 2 stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7653 91177308-0d34-0410-b5e6-96231b3b80d8
