Make various changes suggested by Chris.

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.

an EHFrame section, so we just emit ehframe data into a random section.

This is clearly bad.

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.

llvm-svn: 79250

just remove the argument and replace it with 1.

llvm-svn: 79246

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.

the basic block label printing to check whether a block has a name
before printing a comment character and whitespace for it.

llvm-svn: 78830

that emitted unnecessary whitespace outside of VerboseAsm mode.

llvm-svn: 78828

llvm-svn: 78817

"inlineasmstart/end" strings so that the contents of the directive
are separate from the comment character.  This lets elf targets
get #APP/#NOAPP for free even if they don't use "#" as the comment
character.  This also allows hoisting the darwin stuff up to the
shared TAI class.

the code based on this and make it fall through better.

and short. Well, it's kinda short. Definitely nasty and brutish.

The front-end generates the register/unregister calls into the SjLj runtime,
call-site indices and landing pad dispatch. The back end fills in the LSDA
with the call-site information provided by the front end. Catch blocks are
not yet implemented.

Built on Darwin and verified no llvm-core "make check" regressions.

llvm-svn: 78625

Add support for printing loop structure information in asm comments.
This definitely slows down asm output so put it under an -asm-exuberant
flag.

This information is useful when doing static analysis of performance
issues.

llvm-svn: 78567

This totally optimizes PIC16 sections by not having an 'isdirective' bit anymore!! ;-)

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-svn: 78510

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.

we'll have semantic sections it can hang off of.
