2012-04-16MC assembly parser handling for trailing comma in macro instantiation.Jim Grosbach
A trailing comma means no argument at all (i.e., as if the comma were not present), not an empty argument to the invokee. rdar://11252521 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154863 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-07Output UTF-8-encoded characters as identifier characters into assemblySean Hunt
by default. This is a behaviour configurable in the MCAsmInfo. I've decided to turn it on by default in (possibly optimistic) hopes that most assemblers are reasonably sane. If this proves a problem, switching to default seems reasonable. I'm not sure if this is the opportune place to test, but it seemed good to make sure it was tested somewhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154235 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-06Fixed two leaks in the MC disassembler. The MCSean Callanan
disassembler requires a MCSubtargetInfo and a MCInstrInfo to exist in order to initialize the instruction printer and disassembler; however, although the printer and disassembler keep references to these objects they do not own them. Previously, the MCSubtargetInfo and MCInstrInfo objects were just leaked. I have extended LLVMDisasmContext to own these objects and delete them when it is destroyed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154192 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-28On ELF, create relocations to the abbreviation and line sections when producingRafael Espindola
debug info for assembly files. We were already doing the right thing when producing debug info for C/C++. ELF linkers don't know dwarf, so they depend on these relocations to produce valid dwarf output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151655 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-27ARM BL/BLX instruction fixups should use relocations.Jim Grosbach
We on the linker to resolve calls to the appropriate BL/BLX instruction to make interworking function correctly. It uses the symbol in the relocation to do that, so we need to be careful about being too clever. To enable this for ARM mode, split the BL/BLX fixup kind off from the unconditional-branch fixups. rdar://10927209 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151571 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-17Don't lazily allocate eh_frame. We're not lazily allocating things like the ↵David Chisnall
LSDA, which are only used when the eh frame is used, so this lazy allocation doesn't really make sense.

2012-02-04Modified the Enhanced Disassembler to create andSean Callanan
