Joerg Sonnenberger afb36fad99 Restore r125595 (reverted in r126336) with modifications: 
Introduce a variable in the AsmParserExtension whether [] is valid in an
expression. If it is true, parse them like (). Enable this for ELF only.

Joerg Sonnenberger 4f864d3111 Bug#9172: Don't use static in file scope, use an attribute on the

Rafael Espindola 689939e648 Handle strings in section names the same way as gas: 
* If the name is a single string, we remove the quotes
* If the name starts without a quote, we include any quotes in the name

Rafael Espindola 9f75d5df0b Behave a bit more like gnu as and use the symbol (instead of the section) 
for any relocation to a symbol defined in a tls section.

Rafael Espindola 9bb44a5ce8 Fixed version of 118639 with an extra assert to catch similar problems 
earlier. Implicit bool -> int conversions are evil!

Rafael Espindola 33048f069f Revert previous patch. Missed a case.

Rafael Espindola 8aefb66376 Improvements to .section parsing: 
* If we have a M or a G, reject sections without the type
* Only parse the flag specific arguments if we have M or G
* Parse the corresponding arguments for M and G

We ignore the G arguments and flag for now.

Rafael Espindola 095fa9e5cc Set default type and flags for .init and .fini.

 2010-10-27 18:45:20 +00:00
Rafael Espindola eb0c2c170d Add support for the .symver directive. This is really ugly, but most of it is 
contained in the ELF object writer.

Rafael Espindola c9fb35e73b Add support for .ident.

Michael J. Spencer 3d89823102 MC: Move ParseDirectiveELFType into ELFAsmParser. COFF uses .type for something else.

Jan Wen Voung b96b2d8e4d Have ELFAsmParser.cpp use the already parsed "Size" (entry size) when 
constructing a section. Test for a few cases also included.

Rafael Espindola f7f433200b Make sure that names like .note.GNU-stack are accepted as valid section names.

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.

Daniel Dunbar 8897d479b5 MC/AsmParser: Stop playing unsafe member function pointer calls, this isn't 
portable enough.
 - Downside is we now double dispatch through a stub function, but this isn't
   performance critical.
