* Add support for macro parameters/arguments delimited by spaces,Preston Gurd2012-09-191-22/+120
| | | | | | | | | | to improve compatibility with GNU as. Based on a patch by PaX Team. Fixed assertion failures on non-Darwin and added additional test cases. llvm-svn: 164248
* Support default parameters/arguments for assembler macros.Preston Gurd2012-09-191-7/+31
| | | | | | | | This patch is based on the one by PaX Team. Patch by Andy Zhang! llvm-svn: 164246
* Enhance unmatched '.endr' directive error message in assembler.Preston Gurd2012-09-191-1/+1
| | | | | | | | The directive can be matched with directives other than '.rept' Patch by Andy Zhang! llvm-svn: 164245
* Use LLVM_DELETED_FUNCTION in place of 'DO NOT IMPLEMENT' comments.Craig Topper2012-09-151-2/+2
| | | | llvm-svn: 163970
* Fix Doxygen issues:Dmitri Gribenko2012-09-141-2/+2
| | | | | | | | | | * wrap code blocks in \code ... \endcode; * refer to parameter names in paragraphs correctly (\arg is not what most people want -- it starts a new paragraph); * use \param instead of \arg to document parameters in order to be consistent with the rest of the codebase. llvm-svn: 163902
* Assembler: Darwin variables defined via .set are no-dead-strip.Jim Grosbach2012-09-131-3/+8
| | | | | | | | For gas compatibility. rdar://12219394 llvm-svn: 163854
* Fix alignment of .comm and .lcomm on mingw32.Benjamin Kramer2012-09-071-2/+4
| | | | | | | | For some reason .lcomm uses byte alignment and .comm log2 alignment so we can't use the same setting for both. Fix this by reintroducing the LCOMM enum. I verified this against mingw's gcc. llvm-svn: 163420
* MC: Overhaul handling of .lcommBenjamin Kramer2012-09-071-6/+5
| | | | | | | | | | | | | - Darwin lied about not supporting .lcomm and turned it into zerofill in the asm parser. Push the zerofill-conversion down into macho-specific code. - This makes the tri-state LCOMMType enum superfluous, there are no targets without .lcomm. - Do proper error reporting when trying to use .lcomm with alignment on a target that doesn't support it. - .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2. - Fixes PR13755 (.lcomm crashes on ELF). llvm-svn: 163395

* Make the wording in of the "expected identifier" error in the .macro directiveRafael Espindola2012-08-211-2/+2
| | | | | | | consistent with the other "expected identifier" errors. Extracted from the Andy/PaX patch. I added the test. llvm-svn: 162291

| | | | | | Committing it first as it makes the "real" patch a lot easier to read. llvm-svn: 161491
* Keep empty assembly macro argument values in the middle of the list.Jim Grosbach2012-07-301-2/+8
| | | | | | | | | | | | | | | | | | | Empty macro arguments at the end of the list should be as-if not specified at all, but those in the middle of the list need to be kept so as not to screw up the positional numbering. E.g.: .macro foo foo_-bash___: nop .endm foo 1, 2, 3, 4 foo 1, , 3, 4 Should create two labels, "foo_1_2_3_4" and "foo_1__3_4". rdar://11948769 llvm-svn: 161002

* 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
