Rafael Espindola 72b5488680 Move EmitInstruction to MCObjectStreamer so that ELF and MachO can share it.

Rafael Espindola bce26a1ee0 On ELF we need to know which symbols are used in relocations to decide if 
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

Jason W Kim 645f6c2bef Tiny patch for proof-of-concept cleanup of ARMAsmPrinter::EmitStartOfAsmFile() 
Small test for sanity check of resulting ARM .s file.
Tested against -r115129.

Rafael Espindola 53f0bf194a Move "local commons" to the end of .bss to match the gnu as behavior.

Rafael Espindola 75d65b9a03 Move ELF to HasReliableSymbolDifference=true. Also take the opportunity to put 
symbols defined in merge sections in independent atoms.

Rafael Espindola dee12d8110 Avoid some Mach-O specific alignment being done on ELF.

Rafael Espindola 9bac6cb544 Correctly align bss.

Rafael Espindola f0591c1642 Implement support for .local and its "interesting" interactions with .comm. 
llvm-svn: 114382
 2010-09-21 00:24:38 +00:00
Rafael Espindola f667d929ce Add a InitSections method to the streamer interface. 
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.

Rafael Espindola 9fd2ed9243 Factoring and potential bug fix. The elf "flags" cannot be used as masks. 
For example, setting STT_OBJECT (1) and STT_FUNC (2), should not produce
a STT_SECTION (3).

Roman Divacky 2ef1a589c5 ELF_STB_Local is 0 so setting and checking it must be done specially

Benjamin Kramer 6ebea89316 Mark all common symbols external. This is not exactly correct but it lets apps 
link for now and can be adjusted later. Patch by Roman Divacky.

Matt Fleming 6c1ad4835e Add ELF ObjectWriter and Streamer support. 
I forgot to add these files in commit 111172.
