2010-04-13Replace r101053 with a fix for getSOImmValRotate() so that it will correctlyBob Wilson
recognize all the valid rotated immediates. This fixes the disassembler issue and will also help codegen for some unusual constant values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101114 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Fixed a crasher in arm disassembler within ARMInstPrinter.cpp after callingJohnny Chen
ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2. Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).

2010-04-04Momentous day: remove the "O" member from AsmPrinter. Now all Chris Lattner
"asm printering" happens through MCStreamer. This also Streamerizes PIC16 debug info, which escaped my attention. This removes a leak from LLVMTargetMachine of the 'legacy' output stream. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100327 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-16Initial ARM/Thumb disassembler check-in. It consists of a tablgen backendJohnny Chen
(RISCDisassemblerEmitter) which emits the decoder functions for ARM and Thumb, and the disassembler core which invokes the decoder function and builds up the MCInst based on the decoded Opcode. Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm instructions to help disassembly. We also changed the output of the addressing modes to omit the '+' from the assembler syntax #+/-<imm> or +/-<Rm>. See, for example, A8.6.57/58/60.

2010-03-16Stop using the old pre-UAL syntax for LDM/STM instruction suffixes.Bob Wilson

2010-03-13rearrange MCContext ownership. Before LLVMTargetMachine created it Chris Lattner
and passing off ownership to AsmPrinter. Now MachineModuleInfo creates it and owns it by value. This allows us to use MCSymbols more consistently throughout the rest of the code generator, and simplifies a bit of code. This also allows MachineFunction to keep an MCContext reference handy, and cleans up the TargetRegistry interfaces for AsmPrinters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98450 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13Change ARM ld/st multiple instructions to have variant instructions forBob Wilson
writebacks to the address register. This gets rid of the hack that the first register on the list was the magic writeback register operand. There was an implicit constraint that if that operand was not reg0 it had to match the base register operand. The post-RA scheduler's antidependency breaker did not understand that constraint and sometimes changed one without the other. This also fixes Radar 7495976 and should help the verifier work better for ARM code. There are now new ld/st instructions explicit writeback operands and explicit constraints that tie those registers together. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98409 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-11When outputing a non-lazy pointer for a stub, we may need to fill in the valueBill Wendling
for the NLP because the object it's pointing to may be internal to the file. This seems counter-intuitive, but bear with me. When we place the LSDA into the TEXT section, the type info pointers need to be indirect and pc-rel. We accomplish this by using NLPs. However, sometimes the types are local to the file. GCC gets around this by not using a NLP in this case, but a "regular" indirection like this: GCC_except_tbl: .long Lfoo-. __ZTIA: @ This is local ... Lfoo: .long __ZTIA LLVM prefers NLPs on Darwin. In fact, it's more optimal for load performance to use them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98218 91177308-0d34-0410-b5e6-96231b3b80d8
