Nick Lewycky fb2c1a999a Turn unwind_to into "unwinds to". 
llvm-svn: 48123
 2008-03-10 02:20:00 +00:00
Nick Lewycky 42445be0df Firstly, having a BranchInst isn't exclusive with having an unwind_to. 
Secondly, we have to check whether the branch is actually pointing to the block
with the unwind in it. We could have gotten here because of the unwind_to alone.

Nick Lewycky f3d637fa14 A BB that unwind_to an "unwind" inst is that same as one that doesn't unwind_to 
at all.

Nick Lewycky 5ce9b521d7 Update the inliner and simplifycfg to handle unwind_to.

Chris Lattner f391883670 don't hoist FP additions into unconditional adds + selects. This 
could theoretically introduce a trap, but is also a performance issue.
This speeds up ptrdist/ks by 8%.

Devang Patel 7a2c66b11e If succ has succ itself as one of the predecessors then do 
not merge current bb and succ even if bb's terminator is
unconditional branch to succ.

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.

Chris Lattner a77e74edba Implement PR1796 and Transforms/SimplifyCFG/noreturn-call.ll 
by inserting unreachable after no-return calls.

Chris Lattner 61ce4dff7a Implement PR1786 by iterating between dead cycle elimination 
and simplifycfg in the rare cases when it is needed.

Reid Spencer 4388f0b4fa For PR1146: 
Make ParamAttrsList objects unique. You can no longer directly create or
destroy them but instead must go through the ParamAttrsList::get()
interface.

Reid Spencer a551c041f9 For PR1319: 
Upgrade to use new Tcl exec based test harness. This exposes 3 bugs that
were previously not being reported:
test/Transforms/GlobalDCE/2002-08-17-FunctionDGE.ll
test/Transforms/GlobalOpt/memset.ll
test/Transforms/IndVarsSimplify/exit_value_tests.llx

Reid Spencer d029c7e666 Make the llvm-runtest function much more amenable by eliminating all the 
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.
