* Refactor data-in-code annotations.Jim Grosbach2012-05-189-104/+158
| | | | | | | | | | | | | | | | | | | | | | Use a dedicated MachO load command to annotate data-in-code regions. This is the same format the linker produces for final executable images, allowing consistency of representation and use of introspection tools for both object and executable files. Data-in-code regions are annotated via ".data_region"/".end_data_region" directive pairs, with an optional region type. data_region_directive := ".data_region" { region_type } region_type := "jt8" | "jt16" | "jt32" | "jta32" end_data_region_directive := ".end_data_region" The previous handling of ARM-style "$d.*" labels was broken and has been removed. Specifically, it didn't handle ARM vs. Thumb mode when marking the end of the section. rdar://11459456 llvm-svn: 157062

* MC: Unknown assembler directives are now hard errors.Jim Grosbach2012-05-011-1/+1
| | | | | | | | | | | | | | | | Previously, an unsupported/unknown assembler directive issued a warning. That's generally unsafe, and inconsistent with the behaviour of pretty much every system assembler. Now that the MC assemblers are mature enough to be the default on multiple targets, it's reasonable to issue errors for these. For target or platform directives that need to stay warnings, we should add explicit handlers for them in, e.g., ELFAsmParser.cpp, DarwinAsmParser.cpp, et. al., and issue the warning there. rdar://9246275 llvm-svn: 155926
* MC: Remove errant EatToEndOfStatement() in asm parser.Jim Grosbach2012-05-011-3/+1
| | | | | | | | | | | | The caller is already responsible for eating any additional input on the line. Putting an additional EatToEndOfStatement() in ParseStatement() causes an entire extra statement to be consumed when treating warnings as errors. For example, test/MC/macros.s will assert() because the .endmacro directive is missed as a result. rdar://11355843 llvm-svn: 155925
* MC assembly parser handling for trailing comma in macro instantiation.Jim Grosbach2012-04-161-5/+5
| | | | | | | | | 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 llvm-svn: 154863

| | | | | | | | | | | | | | 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. llvm-svn: 154235
* Fixed two leaks in the MC disassembler. The MCSean Callanan2012-04-062-1/+13
| | | | | | | | | | | | | | | 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. llvm-svn: 154192

* ARM BL/BLX instruction fixups should use relocations.Jim Grosbach2012-02-271-2/+4
| | | | | | | | | | | | | 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 llvm-svn: 151571
