Chris Lattner 4b7dadb76e eliminate AsmPrinter::SwitchToSection and just have clients
talk to the MCStreamer directly instead.

Erick Tryzelaar 9eb4a5f418 Fix gcc-4.4/fedora 11 by adding a sentinel value to SimpleValueType.
gcc-4.4 was optimizing away comparisons against SimpleValueType when
it was compared to a value larger than the largest value in the enum.
This patch works around it by adding one extra item to the enum so
that these tests will now be valid.

Owen Anderson 3042539089 Privatize part of the leak detector mechanism, which turned out to be heavily contended
when trying to run opt in parallel.  This lets parallel opt crunch 403.gcc in about a third
of the time.

Daniel Dunbar 17a6fd2299 raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation.
- Kill off begin(), end(), and iterator. It isn't clear what these
   mean. Instead provide getBufferStart(), which can be used with
   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.

Jakob Stoklund Olesen 36d747745e Simplify RegScavenger::FindUnusedReg.
- Drop the Candidates argument and fix all callers. Now that RegScavenger
  tracks available registers accurately, there is no need to restict the
  search.
- Make sure that no aliases of the found register are in use. This was a potential bug.

Chris Lattner 0adae25ec1 Make AsmStreamer maintain a notion of the current section, pushing it up from the
MCAsmStreamer.  Based on this, eliminate the current section from AsmPrinter.

While I'm at it, clean up the last of the horrible "switch to null section" stuff
and add an assert.  This change is in preparation for completely eliminating 
asmprinter::switchtosection.

Jim Grosbach 486be66dbd Move the sjlj exception handling conversions to a back-end pass where they
more properly belong. This allows removing the front-end conditionalized
SJLJ code, and cleans up the generated IR considerably. All of the
infrastructure code (calling _Unwind_SjLj_Register/Unregister, etc) is
added by the SjLjEHPrepare pass.

Chris Lattner aa1526419c change AsmPrinter to switch sections using AsmStreamer instead of
doing it directly.  This requires const'izing a bunch of stuff that
took sections, but this seems like the right semantic thing to do:
emitting a label to a section shouldn't mutate the MCSection object
itself, for example.

Anton Korobeynikov a6b3ce203a Allow targets to specify their choice of calling conventions per

it could be of use in MakePIC16Libcall, which works unchanged.

Daniel Dunbar 80d484e7cc Update llvm-mc / MCAsmStreamer to print the instruction using the actual target
specific printer (this only works on x86, for now).
 - This makes it possible to do some correctness checking of the parsing and
   matching, since we can compare the results of 'as' on the original input, to
   those of 'as' on the output from llvm-mc.

 - In theory, we could now have an easy ATT -> Intel syntax converter. :)

Daniel Dunbar 95f58463e5 TargetRegistry: Reorganize AsmPrinter construction so that clients pass in the

Owen Anderson 117c9e8497 Add contexts to some of the MVT APIs. No functionality change yet, just the infrastructure work needed to get the contexts to where they need to be first.

Daniel Dunbar c4f8ea4ccb Add 'isCodeGenOnly' bit to Instruction .td records.
- Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.
