2012-07-30Keep empty assembly macro argument values in the middle of the list.Jim Grosbach
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161002 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
