* change EH related stuff (other than EH_LABEL) to use MCSymbolChris Lattner2010-03-1410-129/+115
| | | | | | | | | | | | | | | | | | instead of label ID's. This cleans up and regularizes a bunch of code and makes way for future progress. Unfortunately, this pointed out to me that JITDwarfEmitter.cpp is largely copy and paste from DwarfException/MachineModuleInfo and other places. This is very sad and disturbing. :( One major change here is that TidyLandingPads moved from being called in DwarfException::BeginFunction to being called in DwarfException::EndFunction. There should not be any functionality change from doing this, but I'm not an EH expert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98459 91177308-0d34-0410-b5e6-96231b3b80d8

* rearrange MCContext ownership. Before LLVMTargetMachine created it Chris Lattner2010-03-1319-89/+85
| | | | | | | | | | | | | 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

* Change ARM ld/st multiple instructions to have variant instructions forBob Wilson2010-03-1311-179/+291
| | | | | | | | | | | | | | | | 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

* MC/Mach-O: Implement initial support for relaxation.Daniel Dunbar2010-03-121-9/+117
| | | | | | | | | | | | - The implementation is currently very brain dead and inefficient, but I have a clear plan on how to fix it. - The good news is, it works and correctly assembles 403.gcc (when built with Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g', the resulting binary is exactly equivalent to that when built with the system assembler. So it probably works! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98396 91177308-0d34-0410-b5e6-96231b3b80d8
