Vladimir Medic 27c398e38c This patch implements .set dsp directive and sets appropriate feature bits.This directive is a counterpart of -mattr=dsp command line option with the exception that it does not influence elf header flags. The usage example is gives in test file.

Vladimir Medic 615b26e1cd This patch implements .set mips32r2 directive and sets appropriate feature bits. It also introduces helper functions that are used to set and clear feature bits as necessary. This directive is a counterpart of -mips32r2 command line options with the exception that it does not influence elf header flags. The usage example is gives in test file.

Rafael Espindola 972e71ab5a Remove another hasRawTextSupport.
To remove this one simply move the end of file logic from the asm printer to
the target mc streamer.

This removes the last call to hasRawTextSupport from lib/Target.

Matheus Almeida 2e03f24301 [mips] Fix ELF header flags.
As opposed to GCC/GAS the default ABI for Mips64 is n64.
Compatibility bit should be set if o32 ABI is used when targeting Mips64.

Rafael Espindola 25fa291fb2 Print .mask and .fmask with the target streamer.
Testing this also found the missing '\n' after .frame that this patch also
fixes.

Rafael Espindola cb1953f6d9 Implement the missing bits corresponding to .mips_hack_elf_flags.
These were:
* noreorder handling on the target object streamer and asm parser.
* setting the initial flag bits based on the enabled features.
* setting the elf header flag for micromips

It is *really* depressing I am the one doing this instead of someone at
mips actually taking the time to understand the infrastructure.

Rafael Espindola 24ea09ef7d Construct the MCStreamer before constructing the MCTargetStreamer.
This has a few advantages:
* Only targets that use a MCTargetStreamer have to worry about it.
* There is never a MCTargetStreamer without a MCStreamer, so we can use a
  reference.
* A MCTargetStreamer can talk to the MCStreamer in its constructor.

Rafael Espindola 14d02fe5c8 This reverts commit r200064 and r200051.
r200064 depends on r200051.

r200051 is broken: I tries to replace .mips_hack_elf_flags, which is a good
thing, but what it replaces it with is even worse.

The new emitMipsELFFlags it adds corresponds to no assembly directive, is not
marked as a hack and is not even printed to the .s file.

The patch also introduces more uses of hasRawTextSupport.

The correct way to remove .mips_hack_elf_flags is to have the mips target
streamer handle the default flags (and command line options). That way the
same code path is used for asm and obj. The streamer interface should *really*
correspond to what is printed in the .s file.

Jack Carter ca2ae49d55 [Mips] TargetStreamer ELF flag Support for default and commandline options.
This patch uses a common MipsTargetSteamer interface for both 
MipsAsmPrinter and MipsAsmParser for recording default and commandline
driven directives that affect ELF header flags.

It has been noted that the .ll tests affected by this patch belong in
test/Codegen/Mips. I will move them in a separate patch.

Also, a number of directives do not get expressed by AsmPrinter in the 
resultant .s assembly such as setting the correct ASI. I have noted this
in the tests and they will be addressed in later patches.

Jack Carter 39536724a7 [Mips] TargetStreamer Support for .set mips16.
This patch updates .set mips16 support which
affects the ELF ABI and its flags. In addition the patch uses
a common interface for both the MipsTargetSteamer and
MipsObjectStreamer that the assembler uses for
both ELF and ASCII output for these directives.

Rafael Espindola 26e917cde0 Only mark functions as micromips.
The GNU as behavior is a bit different and very strange. It will mark any
label that contains an instruction. We can implement that, but using the
type looks more natural since gas will not mark a function if a .word is
used to output the instructions!

Rafael Espindola 6633d57ae4 Fix a low hanging use of hasRawTextSupport.
This also fixes the placement of the function label comment. It was being
placed next to the mips16 directive instead of next to the label.

Rafael Espindola 6d5f7ce348 Replace .mips_hack_stocg with ".set micromips" and ".set nomicromips".
This matches what gnu as does and implementing this is easier than arguing
about it.

Chandler Carruth 8a8cd2bab9 Re-sort all of the includes with ./utils/sort_includes.py so that
subsequent changes are easier to review. About to fix some layering
issues, and wanted to separate out the necessary churn.

Also comment and sink the include of "Windows.h" in three .inc files to
match the usage in Memory.inc.

Jack Carter 0cd3c19f33 [Mips] TargetStreamer Support for .abicalls and .set pic0.
This patch adds .abicalls and .set pic0 support which
affects the ELF ABI and its flags. In addition the patch uses
a common interface for both the MipsTargetSteamer and
MipsObjectStreamer that both the integrated and standalone
assemblers will use for the output for these directives.

Jack Carter b9fd457a32 [Mips] Support for MicroMips STO refactoring.
No true functional changes.

Change the "hack" name of emitMipsHackSTOCG to emitSymSTO.

Remove demonstration code in AsmParser for emitMipsHackSTOCG and
emitMipsHackELFFlags. The STO field is in an ELF symbol and is not
an explicit directive. That said, we are missing the compliment call
in AsmParser and that will need to be addressed soon.

XFAIL dummy tests for emitMipsHackELFFlags and emitMipsHackELFFlags.
These will built out with following patches.
