Roman Divacky 9a58919c8e Enumerate .code16/32/64 instead of checking .code prefix. This 
unbreaks some ARM tests.

Roman Divacky bd59dff739 Error on all .code* directives instead of just .code16 as they 
all lead to a silent miscompilation of code.

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

Evan Cheng d4a5c05c97 Completed :lower16: / :upper16: support for movw / movt pairs on Darwin. 
- Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first.
- Added support for Thumb2 :lower16: and :upper16: fix up.
- Added :upper16: and :lower16: relocation support to mach-o object writer.

Evan Cheng 52899a9c34 Add comment about Thumb2 fixup comments being completely bogus.

 2011-01-13 23:27:39 +00:00
Evan Cheng 0447d30939 Relax an assertion. On archs like ARM, an immediate field may be scattered. So it's possible for some bits of every 8 bits to be encoded already, and the rest still needs to be fixed up. 
llvm-svn: 123403
 2011-01-13 21:45:26 +00:00
Evan Cheng 965b3c7323 Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step 
in the right direction. It eliminated some hacks and will unblock codegen
work. But it's far from being done. It doesn't reject illegal expressions,
e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

Jason W Kim 39e36e7ab4 Style clean up - break up the breaks.

 2011-01-13 00:07:51 +00:00
Jason W Kim 9c5b65d289 1. Support ELF pcrel relocations for movw/movt: 
R_ARM_MOVT_PREL and R_ARM_MOVW_PREL_NC.
2. Fix minor bug in ARMAsmPrinter - treat bitfield flag as a bitfield, not an enum.
3. Add support for 3 new elf section types (no-ops)

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 :-)
