Owen Anderson 2a6adfa4f0 Remove GCSE and LoadVN from the testsuite. 
llvm-svn: 54832
 2008-08-16 00:00:54 +00:00
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!

Chris Lattner b76ad168dc Fix PR2346 by marking vaarg as volatile so that licm doesn't try to 
hoist them.

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.

Owen Anderson ecc12fe81d Use loop deletion instead of ADCE in these tests.

Duncan Sands 8a3e9d2bee Ding dong, the DoesntAccessMemoryFns and 
OnlyReadsMemoryFns tables are dead!  We
get more, and more accurate, information
from gcc via the readnone and readonly
function attributes.

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.

Devang Patel 9e30e1a3be Do not promote null values because it may be unsafe to do so.

Devang Patel 464276f831 Avoid unsafe promotion.

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.
