Chris Lattner 903add84d9 Enhance DSE to handle the variable index case in PR8657. 
llvm-svn: 120498
 2010-11-30 23:43:23 +00:00
Chris Lattner c0f3379ae0 teach DSE to use GetPointerBaseWithConstantOffset to analyze 
may-aliasing stores that partially overlap with different base
pointers.  This implements PR6043 and the non-variable part of
PR8657

Chris Lattner 43e3a98675 clean up DSE tests, removing some poorly reduced and useless old test, 
merging more into other larger .ll files, filecheckizing along the way.

Dan Gohman 02538ac4d3 Make BasicAliasAnalysis a normal AliasAnalysis implementation which 
does normal initialization and normal chaining. Change the default
AliasAnalysis implementation to NoAlias.

Update StandardCompileOpts.h and friends to explicitly request
BasicAliasAnalysis.

Update tests to explicitly request -basicaa.

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.

Dan Gohman 9737a63ed8 Change these tests to feed the assembly files to opt directly, instead 
of using llvm-as, now that opt supports this.
