History

Jakob Stoklund Olesen 1f386c4ce1 Don't try to constant fold libm functions with non-finite arguments. Usually we wouldn't do this anyway because llvm_fenv_testexcept would return an exception, but we have seen some cases where neither errno nor fenv detect an exception on arm-linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114893 91177308-0d34-0410-b5e6-96231b3b80d8		2010-09-27 21:29:20 +00:00

This directory contains test cases for the instcombine transformation.  The
dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
