| | | | | | | | for now. - Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80484 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: Support .zerofill emission.Daniel Dunbar2009-08-28
| | | | | | - I'm still trying to figure out the cleanest way to implement this and match the assembler, currently there are some substantial differences. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80347 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc/Mach-O: Unique sections properly, so we don't get duplicate textDaniel Dunbar2009-08-26
| | | | | | | | | sections, etc. - The quick and dirty way, just clone the TargetLoweringObjectFile code. Eventually this should be shared... somehow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80168 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.Daniel Dunbar2009-08-26
| | | | | | | | | - 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80162 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Set .subsections_via_symbols flag properly.Daniel Dunbar2009-08-26
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80144 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Add support for relocations.Daniel Dunbar2009-08-26
| | | | | | | | | | - 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80089 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc/Mach-O: Add section padding where needed (to align the next section).Daniel Dunbar2009-08-26
| | | | | | | Also, simplify some of Mach-O writer code which can now use section addresses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80067 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80065 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc: Improve indirect symbol support (add the indirect index table).Daniel Dunbar2009-08-26
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80059 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Support symbol attributes.Daniel Dunbar2009-08-24
| | | | | | | | - This is mostly complete, the main thing missing is .indirect_symbol support (which would be straight-forward, except that the way it is implemented in 'as' makes getting an exact .o match interesting). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79899 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc/Mach-O: Improve symbol table support:Daniel Dunbar2009-08-22
| | | | | | | | | | | | - Honor .globl. - Set symbol type and section correctly ('nm' now works), and order symbols appropriately. - Take care to the string table so that the .o matches 'as' exactly (for ease of testing). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79740 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: Improve handling of implicit alignment for magic section directivesDaniel Dunbar2009-08-21
| | | | | | | | | (e.g., .objc_message_refs). - Just emit a .align when we see the directive; this isn't exactly what 'as' does but in practice it should be ok, at least for now. See FIXME. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79697 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: Start MCAssembler and MCMachOStreamer.Daniel Dunbar2009-08-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Together these form the (Mach-O) back end of the assembler. - MCAssembler is the actual assembler backend, which is designed to have a reasonable API. This will eventually grow to support multiple object file implementations, but for now its Mach-O/i386 only. - MCMachOStreamer adapts the MCStreamer "actions" API to the MCAssembler API, e.g. converting the various directives into fragments, managing state like the current section, and so on. - llvm-mc will use the new backend via '-filetype=obj', which may eventually be, but is not yet, since I hear that people like assemblers which actually assemble. - The only thing that works at the moment is changing sections. For the time being I have a Python Mach-O dumping tool in test/scripts so this stuff can be easily tested, eventually I expect to replace this with a real LLVM tool. - More doxyments to come. I assume that since this stuff doesn't touch any of the things which are part of 2.6 that it is ok to put this in not so long before the freeze, but if someone objects let me know, I can pull it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79612 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-mc: Fix bugs where bytes were unintentionally being printed as signed.Daniel Dunbar2009-08-14
| | | | | | | | - We now print all of 403.gcc cleanly (llvm-mc -> 'as' as diffed to 'as'), minus two 'rep;movsl' instructions (which I missed before). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79031 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-mc: When handling a .set, make sure to print subsequent references to theDaniel Dunbar2009-08-14
| | | | | | | | | symbol as the symbol name itself, not the expression it was defined to. These have different semantics due to the quirky .set behavior (which absolutizes an expression that would otherwise be treated as a relocation). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79025 91177308-0d34-0410-b5e6-96231b3b80d8
