Bill Wendling dc09af3ef5 Nuke moribund "std::string" version of EOL(..., Encoding). 
llvm-svn: 80466
 2009-08-30 00:28:57 +00:00
Bill Wendling 39bb29f7fe - Add target lowering methods to get the preferred format for the FDE and LSDA 
encodings.
- Make some of the values emitted by the FDEs dependent upon the pointer
  size. This is in line with how GCC does things. And it has the benefit of
  working for Darwin in 64-bit mode now.

Bill Wendling f8b28e4327 Add a form of EOL which emits the text version of a DWARF format encoding. This 
doesn't handle all values of the formatting. Those can be added as needed.

Eric Christopher 743dc0ef40 Make the augmentation size and next set of bytes agree on size, 
and make the reference pointer size as it should be.

Fixes an abort on a testcase derived from libunwind's personality
test in 64-bit.

Devang Patel 3082c01d68 Closure is a very generic name. Use AppleBlock instead.

Despite common miscomceptions, iterator.h is alive and well. It broke the build
bots for several hours. And yet no one bothered to look at them.

Gabor and Doug, please review your changes and make sure that they actually
build before resubmitting them.

Eric Christopher a258c62ea1 If we're emitting additional CIEs due to personality functions 
don't emit the default one. Explicitly check for the NULL
CIE later.

Devang Patel a1b4dd96f2 Add isClosure() predicate. This is used to add DW_AT_APPLE_block attribute. 
Patch by Caroline Tice.

Bill Wendling e98ee2a534 - Rename EmitCommonInformationEntry to EmitCIE. 
- Rename EmitFunctionDescriptionEntry to EmitFDE.

Devang Patel 02aac922b4 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!)

- Fix comment.

Bill Wendling d7ace1e530 Rename functions to something more descriptive. At the very least mention the 
CIE and FDE in their names.

Chris Lattner 06fa176862 prune the #includes in raw_ostream.h by moving a 
member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

llvm-svn: 79885
 2009-08-24 03:52:50 +00:00
Chris Lattner c521f54198 Prune #includes from llvm/Linker.h and llvm/System/Path.h, 
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.

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

llvm-svn: 79346
 2009-08-18 16:56:17 +00:00
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.

llvm-svn: 79324
 2009-08-18 06:15:16 +00:00
Chris Lattner 5de2e2de93 add a horrible hack to the dwarf printer. It looks like mingw is not specifying 
an EHFrame section, so we just emit ehframe data into a random section.

This is clearly bad.

Jim Grosbach 43bbb9de66 Remove a bit more cruft from the sjlj moving to a backend pass. 
llvm-svn: 79272
 2009-08-17 20:25:04 +00:00
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 ee97b8b11c the MinPad argument to PadToColumn only really makes sense to be 1, 
just remove the argument and replace it with 1.

llvm-svn: 79246
 2009-08-17 15:48:08 +00:00
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.

PrintUnmangledNameSafely.

Dan Gohman aceb935add Fix a few more places to use PadToColumn instead of tabs. And fix 
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
 2009-08-12 18:47:05 +00:00
Dan Gohman 942d2857ef Use PadToColumn instead of tabs for aligning comments. Fix one place 
that emitted unnecessary whitespace outside of VerboseAsm mode.

 2009-08-12 17:38:44 +00:00
Chris Lattner abdcbc7ef2 Change the asmprinter to print the comment character before the 
"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.
