Chris Lattner f3ebc3f3d2 Remove attribution from file headers, per discussion on llvmdev. 
llvm-svn: 45418
 2007-12-29 20:36:04 +00:00
Duncan Sands 3353ed09ac Rename isNoReturn to doesNotReturn, and isNoUnwind to 
doesNotThrow.

Duncan Sands 9f76be61d1 Make PruneEH update the nounwind/noreturn attributes 
on functions as it calculates them.

Duncan Sands 38ef3a8ec7 Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

Chris Lattner 19970e62e7 update file comment. 
llvm-svn: 44543
 2007-12-03 19:43:18 +00:00
Duncan Sands 5208d1ab4a Add some convenience methods for querying attributes, and 
use them.

Duncan Sands ad0ea2d430 Fix PR1146: parameter attributes are longer part of 
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

Duncan Sands b23192f483 Remove some logic I thoughtlessly copied over 
from the old ADCE implementation (there it was
correct because the transform was being done
for read-only functions).

llvm-svn: 44287
 2007-11-23 09:10:17 +00:00
Duncan Sands a915b538d3 Turn invokes of nounwind functions into ordinary calls. 
llvm-svn: 44280
 2007-11-22 22:24:59 +00:00
Chris Lattner a77e74edba Implement PR1796 and Transforms/SimplifyCFG/noreturn-call.ll 
by inserting unreachable after no-return calls.

llvm-svn: 44099
 2007-11-14 06:19:25 +00:00
Chris Lattner 61ce4dff7a Implement PR1786 by iterating between dead cycle elimination 
and simplifycfg in the rare cases when it is needed.

Gordon Henriksen d568767ecb Finishing initial docs for all transformations in Passes.html. 
Also cleaned up some comments in source files.

Nick Lewycky e7da2d6ac3 Fix typo in comment.

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652
 2007-05-02 21:39:20 +00:00
Devang Patel 09f162ca6a Do not use typeinfo to identify pass in pass manager. 
llvm-svn: 36632
 2007-05-01 21:15:47 +00:00
Chris Lattner 108083edff Use a worklist-driven algorithm instead of a recursive one. 
llvm-svn: 35680
 2007-04-05 01:27:02 +00:00
Chris Lattner a5403a587c switch MarkAliveBlocks over to using SmallPtrSet instead of std::set, speeding 
up simplifycfg by 20%

Reid Spencer 557ab15e71 Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes in 
the Transforms library. This reduces debug library size by 132 KB, debug
binary size by 376 KB, and reduces link time for llvm tools slightly.

 2007-02-05 23:32:05 +00:00
Chris Lattner 79a42ac941 Switch over Transforms/Scalar to use the STATISTIC macro. For each statistic 
converted, we lose a static initializer.  This also allows GCC to emit warnings
about unused statistics.

llvm-svn: 32690
 2006-12-19 21:40:18 +00:00
Reid Spencer efe5c862f1 Incorporate any changes in the successor blocks into the result of 
MarkAliveBlocks.

Chris Lattner 700b873130 Detemplatize the Statistic class. The only type it is instantiated with 
is 'unsigned'.

Chris Lattner c2d3d3112e eliminate RegisterOpt. It does the same thing as RegisterPass.

Chris Lattner 257b284038 Hrm, some people complain when the compiler cheerfully tells them what it's 
doing... I guess they're right.

Chris Lattner a67dd32004 Turn store -> null/undef into the LLVM unreachable instruction! This simple 
change hacks off 10K of bytecode from perlbmk (.5%) even though the front-end
is not generating them yet and we are not optimizing the resultant code.
This isn't too bad.

Reid Spencer 7c16caa336 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Chris Lattner bf3a099a62 Updates to work with recent Statistic's changes: 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
    * Updated ProgrammersManual with new semantics.
