* Wire up primitive support in the assembler backend for writing .o filesChris Lattner2010-11-151-1/+4
| | | | | | | | | | | | | | | | directly on the mac. This is very early, doesn't support relocations and has a terrible hack to avoid .machine from being printed, but despite that it generates an bitwise-identical-to-cctools .o file for stuff like this: define i32 @test() nounwind { ret i32 42 } I don't plan to continue pushing this forward, but if anyone else was interested in doing it, it should be really straight-forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119136 91177308-0d34-0410-b5e6-96231b3b80d8

* Turn on the new instprinter by default.Chris Lattner2010-11-151-1/+1
| | | | | | | | | | | | | | | | The only change in the output is: 1) we get a better comment on mfcr, we get: mfcr r2 ; cr2 instead of: mfcr r2 ; 32 2) we no longer emit $stub's on powerpc/leopard. The Leopard linker autosynthesizes them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119108 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | are represented as "weak", but there are subtle differences in some cases on Darwin, so we need both.

* Recommitting EH patch; this should answer most of theDale Johannesen2008-04-021-1/+2
| | | | | | | | | | | | | | | | | review feedback. -enable-eh is still accepted but doesn't do anything. EH intrinsics use Dwarf EH if the target supports that, and are handled by LowerInvoke otherwise. The separation of the EH table and frame move data is, I think, logically figured out, but either one still causes full EH info to be generated (not sure how to split the metadata correctly). MachineModuleInfo::needsFrameInfo is no longer used and is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49064 91177308-0d34-0410-b5e6-96231b3b80d8
