2003-07-10Several fixes to handling of int CC register:Vikram S. Adve
(1) An int CC live range must be spilled if there are any interferences, even if no other "neighbour" in the interf. graph has been allocated that reg. yet. This is actually true of any class with only one reg! (2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must be spilled so that the machine-independent spill code doesn't have to make the machine-dependent decision of which CC name to use based on operand type: %xcc or %icc. (These are two halves of the same register.) (3) LR->isMarkedForSpill() is no longer the same as LR->hasColor(). These should never have been the same, and this is necessary now for #2. (4) All RDCCR and WRCCR instructions are directly generated with the phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to deal with this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7151 91177308-0d34-0410-b5e6-96231b3b80d8
2003-07-06Major bug fix though it happened rarely (only on a compare after anVikram S. Adve
integer overflow): We need to use %icc and not %xcc for comparisons on 32-bit or smaller integer values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7111 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-14Allow emission of names that start with an underscore. This is needed toChris Lattner
interface with code that uses symbols in the ansi-c protected namespace. In most cases this comes from system header files, such as stdio.h. In particular, without this change, a reference to the __iob symbol is mangled into ll_iob, which is not resolved by libc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4165 91177308-0d34-0410-b5e6-96231b3b80d8
2002-10-13Several major fixes, particularly in emitting constant aggregates:Vikram S. Adve
(1) Padding bytes between structure fields (for alignment) were never being emitted into the constant pool so the layout did not match! (2) In printing constants, structures containing structures or arrays were never handled. (3) Support new model for external/uninitialized/initialized globals. Uninitialized globals are no longer emitted since they are external. Initialized globals may go either in .bss or in .data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4134 91177308-0d34-0410-b5e6-96231b3b80d8

2002-05-19Numerous bug fixes:Vikram S. Adve
-- correct sign extensions for integer casts and for shift-by-constant instructions generated for integer multiply -- passing FP arguments to functions with more than 6 arguments -- passing FP arguments to varargs functions -- passing FP arguments to functions with no prototypes -- incorrect stack frame size when padding a section -- folding getelementptr operations with mixed array and struct indexes -- use uint64_t instead of uint for constant offsets in mem operands -- incorrect coloring for CC registers (both int and FP): interferences were being completely ignored for int CC and were considered but no spills were marked for fp CC! Also some code improvements: -- better interface to generating machine instr for common cases (many places still need to be updated to use this interface) -- annotations on MachineInstr to communicate information from one codegen phase to another (now used to pass information about CALL/JMPLCALL operands from selection to register allocation) -- all sizes and offests in class TargetData are uint64_t instead of uint git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2640 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-27* Rename MethodPass class to FunctionPassChris Lattner
- Rename runOnMethod to runOnFunction * Transform getAnalysisUsageInfo into getAnalysisUsage - Method is now const - It now takes one AnalysisUsage object to fill in instead of 3 vectors to fill in - Pass's now specify which other passes they _preserve_ not which ones they modify (be conservative!) - A pass can specify that it preserves all analyses (because it never modifies the underlying program) * s/Method/Function/g in other random places as well git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2333 91177308-0d34-0410-b5e6-96231b3b80d8
