Dan Gohman 032d89828e Add explicit keywords and remove spurious trailing semicolons.

Bill Wendling 48597b4ff8 The personality function might need to be declared as: 
.set  Lset0,___gxx_personality_v0-.
    .long Lset0

on some targets. Make it so!

Anton Korobeynikov 64b64ae591 Minor cleanup: 
- Split EH and debug infiormation
 - Make DwarfWriter more verbose in some cases

Dan Gohman b6a8ae20c7 Fix some uses of dyn_cast to be uses of cast.

Duncan Sands 0263dd1d7f The type ids making up a filter are unsigned, and 
should be output as unsigned values.  Checked against
gcc.

llvm-svn: 39775
 2007-07-12 13:51:39 +00:00
Duncan Sands c5b1984f57 Indexes into the list of filter ids cannot be output 
directly: they need to be turned into byte offsets
(often the same, but may not be if there are many
type infos).

Duncan Sands dc8fc1550e Use more realistically sized vectors. Reserve capacity if we know in advance 
how much will be used.

llvm-svn: 37515
 2007-06-08 08:59:11 +00:00
Duncan Sands 29d1dc6f1a Fold the exception actions table harder: if two typeid lists start the 
same, only output one copy of the common part.

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.

Anton Korobeynikov 3b327826db Mark all calls as "could throw", when exceptions are enabled. Emit necessary LP info too. This fixes PR1439 
llvm-svn: 37311

Owen Anderson 0ae7eb5e7c Silence a warning. 
llvm-svn: 37288
 2007-05-22 18:13:40 +00:00
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.

llvm-svn: 37104
 2007-05-16 12:12:23 +00:00
Duncan Sands 750e8c5d4d The index into the actions table is a ULEB128 not a SLEB128. 
llvm-svn: 37084
 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.

Anton Korobeynikov 96142de3f0 Allow multiple invokes per landing pad. This (probably) fixes PR1410.

 2007-05-10 15:10:34 +00:00
Duncan Sands 00282a21a5 Use the personality function that was registered with MMI rather than 
hardwiring in the C++ one.

llvm-svn: 36789
 2007-05-05 20:27:00 +00:00
Duncan Sands 02528f5425 Spelling fix. 
llvm-svn: 36781
 2007-05-05 16:32:57 +00:00
Anton Korobeynikov 4db0090339 Emit sections/directives in the proper order. This fixes PR1376. Also, 
some small cleanup was made.

llvm-svn: 36780
 2007-05-05 09:04:50 +00:00
Anton Korobeynikov b538f67b1a Fix couple of bugs connected with eh info: 
1. Correct output offsets on Linux
2. Fix "style" of personality function. It shouldn't be indirect.
