2003-07-02* If compiling on X86 or Sparc, automagically enable the JIT for that archMisha Brukman
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will force the inclusion of that JIT on a different architecture * If neither JIT is enabled (e.g., compiling on a different architecture), the -march option will not be available to LLI. * As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit faster by not including the x86 library. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7070 91177308-0d34-0410-b5e6-96231b3b80d8

area to avoid using up precious stack space within the 4095 offset limit from %fp. Such objects that would themselves live at a large offset were being put there already so this is a simple change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7066 91177308-0d34-0410-b5e6-96231b3b80d8

2003-07-02Minor beautification: fold a couple of lines of code.Vikram S. Adve

2003-07-02(1) Major bug fix: DecomposeArrayRef() replaces its argument instr. andVikram S. Adve
deletes it, but we were merrily trying to fix the operands of that instruction anyway! Instead, fix the replacement instruction. (2) An Improvement: Check for and extract global values in all operands, not just in known pointer operands. For example, they can occur in call arguments, and probably other unforeseeable places as well. This also eliminates the special-case handling of Load and Store. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7053 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-02A def. operand of a machine instruction may be an ordinary Value*,Vikram S. Adve
not just an Instruction*, at least in one unfortunate case: the first operand to the va_arg instruction. Modify ValueToDefVecMap to map from Value*, not Instruction*. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7052 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-02Bug/case fixes:Vikram S. Adve
(1) select: Ok to convert a pointer to a float or double. (2) regalloc: Some MachineInstr* for caller-saving code before a call were being inserted before and after the call! (3) Don't insert the caller-saving instructions in the MachineCodeForInstruction for the Call instruction. *All* instructions generated by register allocation need to be recorded in those maps, but it needs to be done uniformly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7051 91177308-0d34-0410-b5e6-96231b3b80d8
