2003-06-05Special case simple binary operator X op CChris Lattner
This avoid generating a register to hold C, which in turn speeds up the register allocator by a lot: ~9% on 164.gzip and ~17% on 256.bzip2. This also speeds up other passes. This also speeds up execution of the program marginally, and makes the asm much easier to read. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6626 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-05All store instructions really want 'rd' in the first field.Misha Brukman
Special cases: STFSRx and STXFSRx - they operate on predefined rd=0 or rd=1, and expect %fsr as the parameter in assembly. They are disabled (since not used) until an encoding, both for code generation and output, is chosen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6619 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-04lib/CodeGen/Mapping/MappingInfo.cpp:Brian Gaeke
Update file comment to contain a bunch of the overview mapping-info documentation previously buried within the file. Remove some unnecessary include/using stmts. Rename pass to MappingInfoCollector. Rewrite a lot of it so it doesn't use global instance variables and so it outputs into MappingInfo objects and then dumps those out, instead of going straight to an assembly file. Change name of factory to getMappingInfoCollector. Fold prologue & epilogue writers into MappingInfo methods. lib/Target/Sparc/FInfo.cpp: Correct file comment to reflect above change lib/Target/Sparc/Sparc.cpp: Change name of factory to getMappingInfoCollector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6617 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-04* Instead of re-inventing the MachineConstantPool emitter that's already givenMisha Brukman
in Emitter.cpp, just convert the Sparc version of the constant pool into what's already supported and inter-operate. * Implemented a first pass at lazy function resolution in the JITResolver. That required adding a SparcV9CodeEmitter pointer to simplify generating bit-patterns of the instructions. * SparcV9CodeEmitter now creates and destroys static TheJITResolver, which makes sense because the SparcV9CodeEmitter is the only user of TheJITResolver, and lives for the entire duration of the JIT (via PassManager which lives in VM). * Changed all return values in the JITResolver to uint64_t because of the 64-bit Sparc architecture. * Added a new version of getting the value of a GlobalValue in the SparcV9CodeEmitter, which now works for already-generated functions (JITted or library functions). * Removed little-used and unused functions, cleaning up the internal view of the SparcV9CodeEmitter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6612 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-04* Institute a hack for the Sparc call to mmap() to get our generated code to beMisha Brukman
laid out closer to the VM so that calls to library functions (e.g. puts()) and callback (e.g. JITResolver::CompilationCallback) fit into 30 bits of the call instruction. * Abort if architecture is not yet supported (not X86 or Sparc) because it likely requires a different set of parameters to mmap() . * Stop using hard-coded values for page size; use sysconf(_SC_PAGESIZE) instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6610 91177308-0d34-0410-b5e6-96231b3b80d8

2003-06-04I have finally seen the light. The code to change the opcode must live higher inMisha Brukman
the loop, and in both cases. In the first case, it is a VReg that is a constant so it may be actually converted to a constant. In the second case, it is already a constant, but then if it doesn't change its type (e.g. to become a register and have the value loaded from memory if it is too large to live in its instruction field), we must change the opcode BEFORE the 'continue', otherwise we miss the opportunity. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@6602 91177308-0d34-0410-b5e6-96231b3b80d8
