2011-06-14Diagnostic for undefined assembler local symbols.Jim Grosbach
When an assembler local symbol is used but not defined in a module, a Darwin assembler wants to issue a diagnostic to that effect. rdar://9559714 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133010 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-05Basic support for macros with explicit arguments.Rafael Espindola
We still don't handle * default values * :req * :vararg * \() git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132656 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-02.cfi directive register parsing flexibility.Jim Grosbach
Parsing a register name/number for .cfi directives can't assume that a register name starts with a '%' token. Be more flexible and check for a register number instead. Still unlikely to be perfect, but it allows us to parse both plain identifiers as register names and integers as register numbers, which is what we're wanting to support at this point. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132466 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-01Add new -d option to tblgen. It writes a make(1)-style dependency file.Joerg Sonnenberger
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132395 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Add tests for .seh_setframe and .seh_handlerdata parsing. Fix issues withCharles Davis
them. I had to add a special SwitchSectionNoChange method to MCStreamer just for .seh_handlerdata. If this isn't OK, please let me know, and I'll find some other way to fix .seh_handlerdata streaming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132084 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Add tests for .seh_savereg and .seh_savexmm parsing. Once again, fix theCharles Davis
buggy methods that parse these directives. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132045 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Add a test for .seh_pushframe parsing. Fix the bug exposed by it (and anotherCharles Davis
one I found by inspection). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132037 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-25Add a test for the .seh_handler directive. Fix problems with the parsingCharles Davis
method exposed by the test. While we're at it, simplify the .seh_proc parsing method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132028 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-24Implement the rest of the SEH directive-parsing methods in the COFFAsmParser.Charles Davis
Add a size alignment check to the .seh_stackalloc directive parser. Add a more descriptive error message to the .seh_handler directive parser. Add methods to the TargetAsmInfo struct in support of all this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131992 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-23Propagate error correctly in the MC Asm parser for leading '$' expressions.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131918 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-23Implement .seh_stackalloc and .seh_pushframe parsing.Charles Davis
I haven't implemented any of the ones that take registers yet. The problem is that for x86-64 the streamer methods expect a native x86 register number (note: %r8-%r15 want 8-15 instead of 0-7; same for %xmm8-%xmm15). I haven't figured out exactly how I want to do that yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131899 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-22Add methods to parse the SEH directives to the COFFAsmParser. Implement someCharles Davis
