Devang Patel 57da4caa85 Remove LoopIndexSplit pass. It is neither maintained nor used by anyone. 
llvm-svn: 116004
 2010-10-07 23:29:37 +00:00
Chris Lattner f1144f0929 fix PR8102, a case where we'd copyValue from a value that we already 
deleted.  Fix this by doing the copyValue's before we delete stuff!

The testcase only repros the problem on my system with valgrind.

Chris Lattner be9019090e fix PR8067, an over-aggressive assertion in LICM. 
llvm-svn: 113146

Chris Lattner 50506787d1 fix a bug in my licm rewrite when a load from the promoted memory 
location is being re-stored to the memory location.  We would get
a dangling pointer from the SSAUpdate data structure and miss a 
use.  This fixes PR8068

Chris Lattner affc0e42f0 fix more AST updating bugs, correcting miscompilation in PR8041 
llvm-svn: 112878
 2010-09-02 22:19:10 +00:00
Chris Lattner 030f02021b licm is wasting time hoisting constant foldable operations, 
instead of hoisting them, just fold them away.  This occurs in the
testcase for PR8041, for example.

Chris Lattner 263f804699 LICM does get dead instructions input to it. Instead of sinking them 
out of loops, just delete them.

Devang Patel be94f23992 Remove dead debug info intrinsics. 
Intrinsic::dbg_stoppoint
 Intrinsic::dbg_region_start 
 Intrinsic::dbg_region_end 
 Intrinsic::dbg_func_start
AutoUpgrade simply ignores these intrinsics now.

Dan Gohman cbc6ebb6fd Enable hoisting of loads from constant memory by default. In cases where 
they are lowered to instruction sequences more complex than a simple
load, such that CodeGen cannot rematerialize them, a reload from a
spill slot is likely to be cheaper than the complex sequence.

Edward O'Callaghan e45ac76ee4 Convert a few tests to FileCheck for PR5307. 
llvm-svn: 85171
 2009-10-26 22:52:03 +00:00
Dan Gohman a484d17ec5 Make these tests more interesting by using 
-verify-dom-info and -verify-loop-info, which enable additional
(expensive) consistency checks.

Torok Edwin 907ec36943 LICM shouldn't sink/delete debug information. Fix this and add a testcase. 
For now the metadata of sinked/hoisted instructions is still wrong, but that'll
be fixed when instructions will have debug metadata directly attached.

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 5f36a32e7b Put the LICM of constant GlobalVariables, introduced in r53945, under a 
command-line option, and disable it by default. It introduced performance
regressions because CodeGen is currently not able to remat such loads.

llvm-svn: 53997
 2008-07-24 23:57:25 +00:00
Chris Lattner 8a8fb908dc "Allow LICM to sink or lift loads from constant memory. Also add a test 
case for this.

This allows instructions like loads from global variables declared to
be constant to be moved out of loops."

Patch by Stefanus Du Toit!

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.

Duncan Sands 8a3e9d2bee Ding dong, the DoesntAccessMemoryFns and

Devang Patel 2a60ff1aeb Relax unsafe use check. If there is one unconditional use inside the loop then it is safe to promote value even if there is another conditional use inside the loop.

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.
