Devang Patel 718da668ab PassInfo keep tracks whether a pass is an analysis pass or not.

Devang Patel 864970e9b6 Identify Analysis pass. 
Do not run analysis pass again if analysis info is still available.
This fixes PR1441.

Duncan Sands 68b6f50938 Integrate the readonly/readnone logic more deeply 
into alias analysis.  This meant updating the API
which now has versions of the getModRefBehavior,
doesNotAccessMemory and onlyReadsMemory methods
which take a callsite parameter.  These should be
used unless the callsite is not known, since in
general they can do a better job than the versions
that take a function.  Also, users should no longer
call the version of getModRefBehavior that takes
both a function and a callsite.  To reduce the
chance of misuse it is now protected.

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Reid Spencer 266e42b312 For PR950: 
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.

Reid Spencer 6c38f0bb07 For PR950: 
The long awaited CAST patch. This introduces 12 new instructions into LLVM
to replace the cast instruction. Corresponding changes throughout LLVM are
provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the
exception of 175.vpr which fails only on a slight floating point output
difference.

Chris Lattner bfdd19bc01 Teach globalsmodref-aa to track scalar pointer global variables which point 
to unaliased allocations.  Use this information to disambiguate pointers loaded
from them.  This is a very common case, so it's worthwhile to handle efficiently.

This implements Analysis/GlobalsModRef/indirect-global.ll

Chris Lattner 5de3b8b262 Change the callgraph representation to store the callsite along with the 
target CG node.  This allows the inliner to properly update the callgraph
when using the pruning inliner.  The pruning inliner may not copy over all
call sites from a callee to a caller, so the edges corresponding to those
call sites should not be copied over either.

This fixes PR827 and Transforms/Inline/2006-07-12-InlinePruneCGUpdate.ll

call malloc/free.  This fixes PR555.

Chris Lattner 2a7358064e If we are calling an external function, chain to another AA to potentially 
decide, don't just immediately give up.

This implements GlobalsModRef/chaining-analysis.ll

Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

Chris Lattner a12b5df616 Actually overload the virtual method. This fixes 
Regression/Analysis/GlobalsModRef/purecse.ll.  Isn't this what the
-Woverload-whatever flag would warn about :)

Chris Lattner 4f2cf030e8 'Pass' should now not be derived from by clients. Instead, they should derive 
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

Chris Lattner b696462260 Fix conservative assumption, which was quite broken. Also, notice that 
functions known to not access memory (like sin/cos) don't access memory! :)

Chris Lattner 3a353e84b7 Complete rewrite of this pass to be faster, use less memory, be easier to 
understand, and more accurate to boot!  This implements
GlobalModRef/purecse.ll over the previous impl.

Chris Lattner 26dff501a4 Initial checkin of a simple mod/ref analysis for global variables. This is 
still overly conservative and uses very simple data structures, but it is a
start, and allows elimination of a lot of loads.
