Patch by Caroline Tice.

llvm-svn: 80061

- Rename EmitFunctionDescriptionEntry to EmitFDE.

llvm-svn: 79981

Update DebugInfo interface to use metadata, instead of special named llvm.dbg.... global variables, to encode debugging information in llvm IR. This is mostly a mechanical change that tests metadata support very well.

This change speeds up llvm-gcc by more then 6% at "-O0 -g" (measured by compiling InstructionCombining.cpp!)

llvm-svn: 79977

- Fix comment.

llvm-svn: 79971

CIE and FDE in their names.

llvm-svn: 79969

member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

llvm-svn: 79885

forcing them down into various .cpp files.

This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
   for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
   clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
   instead.
4. Weans llvm-db off <iostream>

sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

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.

llvm-svn: 79324

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.
