* MC/Mach-O: Implement initial support for relaxation.Daniel Dunbar2010-03-121-9/+117
| | | | | | | | | | | | - The implementation is currently very brain dead and inefficient, but I have a clear plan on how to fix it. - The good news is, it works and correctly assembles 403.gcc (when built with Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g', the resulting binary is exactly equivalent to that when built with the system assembler. So it probably works! :) llvm-svn: 98396

* MC/Mach-O: Start passing in the basic MCAsmLayout object.Daniel Dunbar2010-03-111-13/+14
| | | | | | - Also, drop the current location part of AsmLayout, I think I prefer to implement this via explicit symbols. llvm-svn: 98240

* This is the second patch to allow x86 code to be aligned with optimal nops.Kevin Enderby2010-02-231-2/+47
| | | | | | | | | | With the compiler changed to use EmitCodeAlignment() it does change the functionality. But X86 assembly code assembled with llvm-mc does not change its output. For that we will eventually change the assembler frontend to detect a '.align x, 0x90' when used in a section that 'hasInstructions' and use EmitCodeAlignment, but will wait until we have better target hooks. llvm-svn: 96988
* This is the first patch to put the needed bits in place to eventually allow codeKevin Enderby2010-02-231-0/+23
| | | | | | | | | | | to be aligned with optimal nops. This patch does not change any functionality and when the compiler is changed to use EmitCodeAlignment() it should also not change the resulting output. Once the compiler change is made and everything looks good the next patch with the table of optimal X86 nops will be added to WriteNopData() changing the output. There are many FIXMEs in this patch which will be removed when we have better target hooks (coming soon I hear). llvm-svn: 96963

* llvm-mc: Support .zerofill emission.Daniel Dunbar2009-08-281-3/+64
| | | | | | - I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences. llvm-svn: 80347

* llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.Daniel Dunbar2009-08-261-0/+8
| | | | | | | | - I moved section creation back into AsmParser. I think policy decisions like this should be pushed higher, not lower, when possible (in addition the assembler has flags which change this behavior, for example). llvm-svn: 80162

| | | | llvm-svn: 80144
* llvm-mc/Mach-O: Add support for relocations.Daniel Dunbar2009-08-261-13/+225
| | | | | | | | | | - I haven't really tried to find the "right" way to store the fixups or apply them, yet. This works, but isn't particularly elegant or fast. - Still no evaluation support, so we don't actually ever not turn a fixup into a relocation entry. llvm-svn: 80089
