Bill Wendling cdbf17b179 Add support for parsing a Real value. It stores the Real value as its binary 
encoding. It's up to the individual back-ends to convert it to their preferred
representation when printing.

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

 2010-12-29 04:31:26 +00:00
Rafael Espindola 290d71671e Implement cfi_def_cfa. Also don't convert to dwarf reg numbers twice. Looks 
like 6 is a fixed point of that and so the previous tests were OK :-)

 2010-12-25 21:36:35 +00:00
Kevin Enderby fa3c6f148c In llvm-mc parse a Hash token as a full line comment. Allows handling of 
preprocessed .s files and matches darwin gas.  rdar://8798690
Also fix a comment on the next line of AsmParser.cpp after this new code.

llvm-svn: 120145
 2010-11-25 15:32:56 +00:00

 2010-11-16 18:34:07 +00:00
Rafael Espindola 46c79ef113 Fix PR8565. 
This moves most of the isUsed logic to the MCSymbol itself. With this we
get a bit more relaxed about allowing definitions after uses: uses that
don't evaluate their argument immediately (jmp foo) are accepted.

ddunbar, this was the smallest compromise I could think of that lets us
accept gcc (and clang!) assembly.

llvm-svn: 119144
 2010-11-15 14:40:36 +00:00
Rafael Espindola 4bcf94c75a Parse and record the gnu_unique_object type.

Rafael Espindola f01b622902 Parse and remember discriminators in .loc line. I try to output them with

 2010-11-12 15:47:08 +00:00
Rafael Espindola 84d031870c Mark labels declared in tls sections as STT_TLS. This matches the behavior of 
gas.

llvm-svn: 118818
 2010-11-11 19:04:55 +00:00
Rafael Espindola a3e9a2298d Initial comdat implementation. 
llvm-svn: 118805
 2010-11-11 18:13:52 +00:00
Rafael Espindola 9bb44a5ce8 Fixed version of 118639 with an extra assert to catch similar problems 
earlier. Implicit bool -> int conversions are evil!

 2010-11-01 14:28:48 +00:00
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.

Pointed out by Chris!

llvm-svn: 117471
 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.

llvm-svn: 117448
