Victor Hernandez cd94410152 In mem2reg, for all alloca/stores that get promoted where the alloca has an associated llvm.dbg.declare instrinsic, insert an llvm.dbg.var intrinsic before each store.

Chris Lattner 4e849162ef fix a bug exposed by moving SRoA earlier which caused a crash building kc++

Chris Lattner cf295039e4 Fix PR5023: The instruction form of DominatorTree::dominates did not 
take into consideration that the result of an invoke is only valid in
the normal dest, not the unwind dest.  This caused 'PHINode::hasConstantValue'
to return true in an invalid situation, causing mem2reg to delete a phi that
was actually needed.  This caused a crash building 483.xalancbmk.

Dan Gohman 1880092722 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the 
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

Dan Gohman 72a13d2476 Use opt -S instead of piping bitcode output through llvm-dis. 
llvm-svn: 81257
 2009-09-08 22:34:10 +00:00
Dan Gohman 9737a63ed8 Change these tests to feed the assembly files to opt directly, instead 
of using llvm-as, now that opt supports this.

Dan Gohman a5b9645c4b Split the Add, Sub, and Mul instruction opcodes into separate 
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

Gabor Greif 1e427c3264 sabre brings to my attention that the 'tr' suffix is also obsolete

Gabor Greif f45ff35bfe Rename the last test with .llx extension to .ll, resolve duplicate test by renaming to isnan2. Now that no test has llx ending there is no need to search for them from dg.exp too.

Anton Korobeynikov 24fb6b2f8c Don't promote volatile loads/stores. This is needed (for example) to handle setjmp/longjmp properly. 
This fixes PR1520.

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.
