* - Two minor improvements to the MachineInstr class to reduce footprint andChris Lattner2002-10-221-9/+8
| | | | | | | overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a bitvector. Sped up LLC a little less than 10% in a debug build! llvm-svn: 4261
* Major bug fix: spill code for an instruction in a delay slot wasVikram S. Adve2002-10-111-11/+73

* Live ranges for Return value and return address of a Call are nowVikram S. Adve2002-09-281-91/+71
| | | | | | | created here, simply by handling all implicit operands (which should have been done anyway). llvm-svn: 3969

* Add method IGNode::getCombinedDegree to count the sum of the degreesVikram S. Adve2002-09-201-0/+3

* Allow copy coalescing in more cases: if sum of node degrees is more thanVikram S. Adve2002-09-202-1/+26

* Significant changes to correctly spill CC registers and to correctlyVikram S. Adve2002-07-081-239/+164
| | | | | | | | | | | | | | | | | handle conditional move instructions: -- cpMem<->Reg functions now support CC registers (int and FP) correctly. -- Scratch registers must be explicitly provided to cpMem<->Reg when needed, since CC regs need one to be copied to/from memory. -- CC regs are saved to a scratch register instead of stack. -- All regs used by a instruction are now recorded in MachineInstr::regsUsed, since regs used to save values *across* an instruction are not obvious either from the operands or from the LiveVar sets. -- An (explicit or implicit) operand may now be both a def and a use. This is needed for conditional move operations. So an operand may need spill code both before and after the instruction. -- class MachineCodeForBasicBlock is now an annotation on BasicBlock. llvm-svn: 2833
* MachineInstr* in vector are not const (and never really were)Vikram S. Adve2002-07-081-9/+10
| | | | | | | because operands may be modified directly to set register. Also, class MachineCodeForBasicBlock is now an annotation on BasicBlock. llvm-svn: 2832
* getUsableUniRegAtMI interface simplified slightly.Vikram S. Adve2002-07-081-6/+7
| | | | llvm-svn: 2822
* MachineInstr* in vector are not const (and never really were)Vikram S. Adve2002-07-081-1/+1
| | | | | | because operands may be modified directly to set register. llvm-svn: 2820
* Remove tag that just clutters diffsChris Lattner2002-06-301-1/+0
| | | | llvm-svn: 2807
* changes to make it compatible with 64bit gccAnand Shukla2002-06-251-0/+1
| | | | llvm-svn: 2791
* MEGAPATCH checkin.Chris Lattner2002-06-252-145/+127
| | | | | | For details, See: docs/2002-06-25-MegaPatchInfo.txt llvm-svn: 2779
* Convert RegClass::IsColorUsedArr from a dynamically allocated array toChris Lattner2002-05-233-39/+30
| | | | | | a vector. This makes asserting on array bounds easier. llvm-svn: 2731
* Move debug options out of header files so that the header does not haveChris Lattner2002-05-221-5/+4
| | | | | | to #include CommandLine.h. llvm-svn: 2712
* Avoid #including CommandLine.hChris Lattner2002-05-221-4/+2
| | | | llvm-svn: 2710
* Hide debugging optionsChris Lattner2002-05-201-1/+1
| | | | llvm-svn: 2676
* Don't lose namespace qualifications on previous patch.Chris Lattner2002-05-201-2/+2
| | | | llvm-svn: 2664
* InstrnsBefore and InstrnsAfter are now vectors instead of deques.Vikram S. Adve2002-05-191-3/+3
| | | | | | | May be slightly less efficient but significantly reduces special cases interfaces in code generation. llvm-svn: 2649
* Numerous bug fixes:Vikram S. Adve2002-05-192-27/+58
| | | | | | | | | | | | | | | | | | | -- 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 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 llvm-svn: 2642
