2012-05-18Refactor data-in-code annotations.Jim Grosbach
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157062 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-01MC: Unknown assembler directives are now hard errors.Jim Grosbach
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155926 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-01MC: Remove errant EatToEndOfStatement() in asm parser.Jim Grosbach
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155925 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

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
