* Fix parsing of .symver directive on ARMDavid Peixotto2014-01-151-0/+7
| | | | | | | | | | | | | | | ARM assembly syntax uses @ for a comment, execpt for the second parameter of the .symver directive which requires @ as part of the symbol name. This commit fixes the parsing of this directive by adding a special case for ARM for this one argumnet. To make the change we had to move the AllowAtInIdentifier variable to the MCAsmLexer interface (from AsmLexer) and expose a setter for the value. The ELFAsmParser then toggles this value when parsing the second argument to the .symver directive for a target that uses @ as a comment symbol llvm-svn: 199339

* ELF: Parse types in directives like binutils gasDavid Majnemer2013-09-211-20/+43
| | | | | | | | | | Allow binutils .type and .section directives to take the following forms: - @<type> - %<type> - "<type>" llvm-svn: 191134

* MC: Add support for '?' flags in .section directivesDavid Majnemer2013-09-151-2/+20
| | | | | | | | | | | | | | | | | | | Summary: The '?' flag uses the last section group if the last had a section group. We treat combining an explicit section group and the '?' as a hard error.

* Move some ELF directives into ELF asm parser.Jim Grosbach2011-07-251-0/+44
| | | | | | | | | | | | | | The .local, .hidden, .internal, and .protected are not legal for all supported file formats (in particular, they're invalid for MachO). Move the parsing for them into the ELF assembly parser since that's the format they're for. Similarly, .weak is used by COFF and ELF, but not MachO, so move the parsing to the COFF and ELF asm parsers. Previously, using any of these directives on Darwin would result in an assertion failure in the parser; now we get a diagnostic as we should. rdar://9827089 llvm-svn: 135921

| | | | | | | | | | | | | | The ELF implementation now creates text, data and bss to match the gnu as behavior. The text streamer still has the old MachO specific behavior since the testsuite checks that it will error when a directive is given before a setting the current section for example. A nice benefit is that -n is not required anymore when producing ELF files. llvm-svn: 114027
