Jim Laskey f6c63fec92 Repair debug frames as a prelude to eh_frames. Switched to using MachineMoves 
by value so that clean up is less confusing (these vectors tend to be small.)

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.

Bill Wendling f3baad3ee1 Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, are 
now cerr, cout, and NullStream resp.

Jim Laskey 97f89b11b3 Merging dwarf info to a single compile unit. 
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.

is present in a section heading.

Jim Laskey 01c55a50b1 Live local variables are being dropped because the begin or end labels marking 
their scope are being deleted.  Workaround is to widen scope to full function.

Jim Laskey 15d166ba8f 1. Hash not quite right for DIEValues. 
2. Not going to use Usage (no significant benefit.)

llvm-svn: 31382
 2006-11-02 20:55:40 +00:00
Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
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.

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.

 2006-10-30 23:34:32 +00:00
Reid Spencer b51b5c0b1f Add debug support for X86/ELF targets (Linux). This allows llvm-gcc4 
generated object modules to be debugged with gdb. Hopefully this helps
pre-release debugging.
