Duncan Sands 29d1dc6f1a Fold the exception actions table harder: if two typeid lists start the 
same, only output one copy of the common part.

llvm-svn: 37470
 2007-06-06 15:37:31 +00:00
Duncan Sands c063f5f362 Integrate exception filter support and exception catch support. This 
simplifies the code in DwarfWriter, allows for multiple filters and
makes it trivial to specify filters accompanied by cleanups or catch-all
specifications (see next patch).  What a deal!  Patch blessed by Anton.

llvm-svn: 37398
 2007-06-02 16:53:42 +00:00
Anton Korobeynikov 3b327826db Mark all calls as "could throw", when exceptions are enabled. Emit necessary LP info too. This fixes PR1439

Duncan Sands 34e82a4508 Only emit one entry in the exception action table for each action, even if 
it occurs for multiple landing pads.

llvm-svn: 37267
 2007-05-21 18:50:28 +00:00
Duncan Sands 59ae77486c Output exception call-sites in address order, as required by the unwinding 
runtime.

 2007-05-16 12:12:23 +00:00
Duncan Sands 750e8c5d4d The index into the actions table is a ULEB128 not a SLEB128.

 2007-05-15 13:54:14 +00:00
Anton Korobeynikov 1ee0c8d563 Emit function debug frames in one atom. This will prevent us from generating incorrect assembler in case of both 
debug information & exception information presented.

llvm-svn: 37019
 2007-05-13 17:30:11 +00:00
Anton Korobeynikov bbaf55448b Emit multiple common EH frames for multiple (including blank) personality 
functions. This partly fixes PR1414: now we're restricted only to one
personality function per eh frame, not per module. Further work on
"multiple personalities" topic needs representative example.

llvm-svn: 37018
 2007-05-13 15:42:26 +00:00
Anton Korobeynikov 13da17843c More DWARF-related things cleanup: 
1. Fix PR1380
2. Apply Duncan's patch from PR1410
3. Insert workaround for "one personality function per module" as noted in PR1414
4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is
shown correctly, but arguments for function on top of stack are displayed incorrectly.

Bill Wendling a77f14265b Added an automatic cast to "std::ostream*" etc. from OStream. We then can 
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

llvm-svn: 31593
 2006-11-09 14:52:14 +00:00
Jim Laskey 6ea4fae838 1. Add a pass to fold debug label instructions so a debug info client can detect 
empty ranges.

2. Reorg how MachineDebugInfo maintains changes to debug labels.

3. Have dwarf writer use debug label info to simplify scopes and source line
coorespondence.

4. Revert the merging of compile units until I can get the bugs ironed out.

Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting

unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Jim Laskey 936d546eca General clean up of teh dwarf writer. 
1. Most significant is the folding of debug information entries.  This
reduced self hosted -g SelectionDAGISel.s from 120M to 13M and pretty
close to matching .o file sizes with gcc.

2. Debug information entry printing for debugging the dwarf code.

3. Bring all the code closer to llvm standards.

4. Misc. fixes and doc clean ups.

llvm-svn: 31379

Anton Korobeynikov aa4c0f9374 1. Clean up code due to changes in SwitchTo*Section(2) 
2. Added partial debug support for mingw\cygwin targets (the same as
   Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
   for storing debug info by default, thus many (runtime) libraries has
   this information included. These formats shouldn't be mixed in one binary
   ('stabs' & 'DWARF'), otherwise binutils tools will be confused.
