Duncan Sands 2e67937f76 A typeid of zero means a cleanup, not a catch. This case occurs 
when there is both a catch and a cleanup.  Correct the comment.

Renato Golin c8d4065781 add the comments of each declaration follow it, making it easier to read and compare to GCC's result.

Evan Cheng 67c033e6b8 Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions for 
better location welcome).

Bill Wendling ddec6838a9 Add verbose EH table printing to SjLj exception tables. 
llvm-svn: 133561
 2011-06-21 22:40:24 +00:00
Bill Wendling a8339eb0d0 Improve the comment printing for the EH table. This gives a much more detailed 
explanation of what the EH table describes.

Anton Korobeynikov 9be547cfd3 Add a possibility to switch between CFI directives- and table-based frame description emission. Currently all the backends use table-based stuff.

Bill Wendling d9900542a6 Reference the personalities. Don't copy them into a new vector. 
llvm-svn: 109966
 2010-08-01 01:34:21 +00:00
Bill Wendling 95f6ebcb37 Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe what 
the variable actually tracks.

N.B., several back-ends are using "HasCalls" as being synonymous for something
that adjusts the stack. This isn't 100% correct and should be looked into.

Torok Edwin f8dba24a9b Workaround the breakage in r100616 by guarding all timers with 
TimePassesIsEnabled. This should allow make check to pass.

Bill Wendling fcc14141c7 Use the "NamedGroupTimer" class to categorize DWARF emission better.

Chris Lattner a179b52361 move gettemplabel and getdwlabel to AsmPrinter and rename 
them for consistency.

llvm-svn: 100345
 2010-04-04 19:25:43 +00:00
Chris Lattner 9efd118938 move uleb/sleb printing into AsmPrinter from DwarfPrinter. 
llvm-svn: 100344
 2010-04-04 19:09:29 +00:00
Chris Lattner 21dc46e256 remove TargetMachine.h #include, also, TRI isn't used frequently 
enough to warrant caching in AsmPrinter, so remove it.

llvm-svn: 100336
 2010-04-04 18:06:11 +00:00
Chris Lattner 1198002c81 remove the raw_ostream from various dwarf printing things. 
The only thing left is LEB printing, which uses EmitRawText
for now.

 2010-03-29 20:39:38 +00:00
Chris Lattner 6e52e9db31 get MMI out of the label uniquing business, just go to MCContext 
to get unique assembler temporary labels.

llvm-svn: 98489
 2010-03-14 08:36:50 +00:00
Chris Lattner ff1fdd6787 remove now-dead code, all labels use MCSymbols. 
llvm-svn: 98484
 2010-03-14 08:17:53 +00:00
Chris Lattner 04857fab70 fix a bug I introduced in r98459, causing some NNT failures. 
llvm-svn: 98470
 2010-03-14 06:50:56 +00:00
Chris Lattner ee2fbbc978 change the LabelSDNode to be EHLabelSDNode and make it hold 
an MCSymbol.  Make the EH_LABEL MachineInstr hold its label
with an MCSymbol instead of ID.  Fix a bug in MMI.cpp which
would return labels named "Label4" instead of "label4".

llvm-svn: 98463
 2010-03-14 02:33:54 +00:00
Chris Lattner 34adc8d225 change EH related stuff (other than EH_LABEL) to use MCSymbol 
instead of label ID's.  This cleans up and regularizes a bunch 
of code and makes way for future progress.

Unfortunately, this pointed out to me that JITDwarfEmitter.cpp
is largely copy and paste from DwarfException/MachineModuleInfo
and other places.  This is very sad and disturbing. :(

One major change here is that TidyLandingPads moved from being
called in DwarfException::BeginFunction to being called in
DwarfException::EndFunction.  There should not be any 
functionality change from doing this, but I'm not an EH expert.

llvm-svn: 98459
 2010-03-14 01:41:15 +00:00
Chris Lattner 41e275dc8e simplify EmitFrameMoves to take BaseLabel in as a symbol 
instead of as a stem+idx pair, simplify the "is a new 
location" check to use symbol comparison.

llvm-svn: 98432
 2010-03-13 08:05:25 +00:00
Chris Lattner 8811e12314 factor some labels, simplify some code. 
llvm-svn: 98429
 2010-03-13 07:40:56 +00:00
Chris Lattner 45ec3f8944 remove dead code. 
llvm-svn: 98365
 2010-03-12 18:49:32 +00:00
Chris Lattner 71c30c164f move three lowering hooks from MAI to TLOF and make one of them 
semantic instead of syntactic.  This completes MCization of
darwin/x86[-64]!

llvm-svn: 98145
 2010-03-10 07:20:42 +00:00
Chris Lattner eec9bf1198 mcize the rest of EH emission, only one more directive missing 
for darwin/x86 to be completely mcized.

llvm-svn: 98130
 2010-03-10 02:48:06 +00:00
Chris Lattner ac2361a9b0 set the temporary bit on MCSymbols correctly. 
llvm-svn: 98124
 2010-03-10 02:25:11 +00:00
Chris Lattner 7e998b7363 add some fixme's for MCizing. EH still has a few things that 
need to be MCized, but the last debug info thing are LEB and
cygwin specific (which the MC api doesn't support yet) and
one specific form of EmitReference which I'll tackle next.

llvm-svn: 98116
 2010-03-10 01:04:13 +00:00
Chris Lattner caea64b098 mcize uses of PrintRelDirective and eliminate it. 
llvm-svn: 98107
 2010-03-10 00:09:21 +00:00
Chris Lattner 566cae9086 eliminate EOL, adding all comments with the OutStreamer.AddComment 
method.  With this, comments should end up on the same lines as the .byte
directives (for example) and we now get no output with:

$ llc CodeGen/X86/2009-02-12-DebugInfoVLA.ll -o - -filetype=null -asm-verbose

woot.

llvm-svn: 98105
 2010-03-09 23:52:58 +00:00
Chris Lattner 4d728127fb now that the debug and eh emitters use a common .set counter, 
we can eliminate "flavor".

llvm-svn: 98011
 2010-03-09 00:00:15 +00:00
Chris Lattner 27a9732450 simplify EmitSectionOffset to always use .set if it is 
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

llvm-svn: 98005
 2010-03-08 23:23:25 +00:00
Chris Lattner 449a9ff14b Remove a version of EmitDifference. 
llvm-svn: 98002
