* - Add TargetInstrInfo::isIdentical(). It's similar to MachineInstr::isIdenticalEvan Cheng2009-11-071-2/+20
| | | | | | | | | | except it doesn't care if the definitions' virtual registers differ. This is used by machine LICM and other MI passes to perform CSE. - Teach Thumb2InstrInfo::isIdentical() to check two t2LDRpci_pic are identical. Since pc relative constantpool entries are always different, this requires it it check if the values can actually the same. llvm-svn: 86328

* Clean up LSDA name generation and use for SJLJ exception handling. ThisJim Grosbach2009-09-011-3/+4
| | | | | | | | | | | makes an eggregious hack somewhat more palatable. Bringing the LSDA forward and making it a GV available for reference would be even better, but is beyond the scope of what I'm looking to solve at this point. Objective C++ code could generate function names that broke the previous scheme. This fixes that. llvm-svn: 80649

* SjLj based exception handling unwinding support. This patch is nasty, brutishJim Grosbach2009-08-111-1/+1
| | | | | | | | | | | | | and short. Well, it's kinda short. Definitely nasty and brutish. The front-end generates the register/unregister calls into the SjLj runtime, call-site indices and landing pad dispatch. The back end fills in the LSDA with the call-site information provided by the front end. Catch blocks are not yet implemented. Built on Darwin and verified no llvm-core "make check" regressions. llvm-svn: 78625

* Fix some significant problems with constant pools that resulted in ↵Evan Cheng2009-03-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | unnecessary paddings between constant pool entries, larger than necessary alignments (e.g. 8 byte alignment for .literal4 sections), and potentially other issues. 1. ConstantPoolSDNode alignment field is log2 value of the alignment requirement. This is not consistent with other SDNode variants. 2. MachineConstantPool alignment field is also a log2 value. 3. However, some places are creating ConstantPoolSDNode with alignment value rather than log2 values. This creates entries with artificially large alignments, e.g. 256 for SSE vector values. 4. Constant pool entry offsets are computed when they are created. However, asm printer group them by sections. That means the offsets are no longer valid. However, asm printer uses them to determine size of padding between entries. 5. Asm printer uses expensive data structure multimap to track constant pool entries by sections. 6. Asm printer iterate over SmallPtrSet when it's emitting constant pool entries. This is non-deterministic. Solutions: 1. ConstantPoolSDNode alignment field is changed to keep non-log2 value. 2. MachineConstantPool alignment field is also changed to keep non-log2 value. 3. Functions that create ConstantPool nodes are passing in non-log2 alignments. 4. MachineConstantPoolEntry no longer keeps an offset field. It's replaced with an alignment field. Offsets are not computed when constant pool entries are created. They are computed on the fly in asm printer and JIT. 5. Asm printer uses cheaper data structure to group constant pool entries. 6. Asm printer compute entry offsets after grouping is done. 7. Change JIT code to compute entry offsets on the fly. llvm-svn: 66875

| | | | | | | | | | | | | | | | | | | | | | | | use raw_ostream instead of std::ostream. Among other goodness, this speeds up llvm-dis of kc++ with a release build from 0.85s to 0.49s (88% faster). Other interesting changes: 1) This makes Value::print be non-virtual. 2) AP[S]Int and ConstantRange can no longer print to ostream directly, use raw_ostream instead. 3) This fixes a bug in raw_os_ostream where it didn't flush itself when destroyed. 4) This adds a new SDNode::print method, instead of only allowing "dump". A lot of APIs have both std::ostream and raw_ostream versions, it would be useful to go through and systematically anihilate the std::ostream versions. This passes dejagnu, but there may be minor fallout, plz let me know if so and I'll fix it. llvm-svn: 55263

* - Fix codegen for pc relative constant (e.g. JT) in thumb mode:Evan Cheng2007-01-301-7/+23
| | | | | | | | | | | | | | | | | | | .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4)) LPCRELL0: add r1, pc, #PCRELV0 This is not legal since add r1, pc, #c requires the constant be a multiple of 4. Do the following instead: .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4)) LPCRELL0: mov r1, #PCRELV0 add r1, pc - In thumb mode, it's not possible to use .set generate a pc relative stub address. The stub is ARM code which is in a different section from the thumb code. Load the value from a constpool instead. - Some asm printing clean up. llvm-svn: 33664
