* 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

* First part of support for generating dwarf for assembly source files with theKevin Enderby2011-11-011-0/+24
| | | | | | | | | | | | -g flag. In this part we generate the .file for the source being assembled and the .loc's for the assembled instructions. The next part will be to generate the dwarf Compile Unit DIE and a dwarf subprogram DIE for each non-temporary label. Once the next part is done test cases will be added. rdar://9275556 llvm-svn: 143509

| | | | | | | | | | .file filenumber "directory" "filename" This removes one join+split of the directory+filename in MC internals.

* Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang ↵Chris Lattner2011-10-161-19/+19

Enhance the X86 asmparser to produce ranges in the one case that was annoying me, for example: test.s:10:15: error: invalid operand for instruction movl 0(%rax), 0(%edx) ^~~~~~~ It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use ranges where appropriate if someone is interested. llvm-svn: 142106
* Finish supporting cpp #file/line comments in assembler for error messages. SoKevin Enderby2011-10-121-5/+64
