'no_hash' modifier. Hopefully this will make Daniel happy :)

 - Track whether we need to insert an explicit 'break'.

 - Invert conditional when matching a single prefix to reduce
   nesting/bracing/breaking.

 - wc -l of X86GenAsmMatcher.inc decreased by 10%. :)

2. Move section switch printing to MCSection virtual method which takes a
   TAI.  This eliminates textual formatting stuff from TLOF.
3. Eliminate SwitchToSectionDirective, getSectionFlagsAsString, and 
   TLOFELF::AtIsCommentChar.

llvm-mc's purpose yet and we'll want to switch to creating semantic sections
at some point.

bytes for F2 0F 38 and propagate. Add a FIXME for a set
of possibilities which correspond to intrinsics already used.

New test.

Also, redefined MatchRegisterName to just return the register value or a
sentinel, to simplify the generated code.

A TAI hook is appropriate in this case because this is just an
asm syntax issue, not a semantic difference. TLOF should model
the semantics of the section.

Blackfin supports and/or/xor on i32 but not on i16. Teach
DAGCombiner::SimplifyBinOpWithSameOpcodeHands to not produce illegal nodes
after legalize ops.

give the impls an object-file-specific name.  In the future
they can take different arguments etc.

llvm-svn: 78495

now that they create *all* the sections.

much more efficient way than a sequence of if's.  Switch MatchRegisterName
to use it.  It would be nice if someone could factor this out to a shared
place in tblgen :)

Introduce a new PragmaPack attribute, and use it for #pragma pack. The PackedAttr now only represents __attribute__((packed)).

This is necessary because #pragma pack and __attribute__((packed)) have different semantics. No functionality change yet, but this lays the groundwork for fixing a record layout bug.

getFunctionLevelDeclContext needs to get the previous DeclContext if EnterDeclaratorContext has been called. Fixes PR4694. (Doug, please review)

since they are in 64 bit mode with i64immSExt32 imms. JIT is not affected since 
it handles both word absolute relocations in the same way

 - Store edge, block, and function information separately for each functions
   (instead of in one giant map).

 - Return frequencies as double instead of int, and use a sentinel value for
   missing information.

llvm-svn: 78477

Handle large integers, x86_fp80, ConstantAggregateZero, and two more ConstantExpr:
GetElementPtr and IntToPtr
Set SHF_MERGE bit for mergeable strings
Avoid zero initialized strings to be classified as a bss symbol
Don't allow common symbols to be classified as STB_WEAK
Add a constant to be used as a global value offset in data relocations
