Chris Lattner eb3e84078d Do not sort SCEV objects by address: instead sort by complexity and group 
by address.  This prevents the resultant SCEV objects from depending on
where in memory other scev objects happen to live.

Reid Spencer 0277fd7b44 A utility to search the LLVM source tree for a grep pattern. This is a 
replacement for getsrcs.sh which now generates too much text to put on a
Linux command line. The approach taken with llvmgrep is to execute a find
command and execute a grep on each file that matches the name pattern. The
arguments to this script are the same as those of egrep. Note that the -H
and -n options to egrep will always be passed so that you always get the
file and line number of matches.

Chris Lattner 42ad646104 Now that dominator tree children are built in determinstic order, this horrible code 
can go away

llvm-svn: 14254
 2004-06-19 20:23:35 +00:00
Chris Lattner 39396e2df9 compute dominator tree children in a deterministic order that does not depend 
on the address of BasicBlock objects in memory.  This eliminates stuff like this:

 Inorder Dominator Tree:
   [1]  %entry
     [2]  %loopentry
-      [3]  %loopexit
       [3]  %no_exit
-        [4]  %endif
         [4]  %then
+        [4]  %endif
+      [3]  %loopexit
       [3]  %return

Chris Lattner ec2d34cc19 Fix one source of nondeterminism in the -licm pass: the hoist pass 
was processing blocks in whatever order they happened to end up in the
dominator tree data structure.  Force an ordering.

Chris Lattner d31410d824 Initial checkin of the StableBasicBlockNumbering, a little helper class for computing 
(strangely enough) a stable (determinstic) numbering for basic blocks.

Chris Lattner feda9d0583 Fix a tiny bug in the -no-aa pass, in which it did not ever get a target data. 
This is a regression from 1.2, though noone uses -no-aa anyway

Chris Lattner a52ab6f57f Do not let the numbering of PHI nodes placed in the function depend on 
non-deterministic things like the ordering of blocks in the dominance
frontier of a BB.  Unfortunately, I don't know of a better way to solve
this problem than to explicitly sort the BB's in function-order before
processing them.  This is guaranteed to slow the pass down a bit, but
is absolutely necessary to get usable diffs between two different tools
executing the mem2reg or scalarrepl pass.

Before this, bazillions of spurious diff failures occurred all over the
place due to the different order of processing PHIs:

-       %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.0, uint 0, uint 0
+       %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.1, uint 0, uint 0

Now, the diffs match.

Chris Lattner b2b151d297 Do not sort by the address of LLVM ConstantInt* objects. This produces 
nondeterministic results that depend on where these objects land in memory.
Instead, sort by the value of the constant, which is stable.

Before this patch, the -simplifycfg pass run from two different compilers
could cause different code to be generated, though it was semantically the
same:

@@ -12258,8 +12258,8 @@
        %s_addr.1 = phi sbyte* [ %s, %entry ], [ %inc.0, %no_exit ]             ; <sbyte*> [#uses=5]

We need to stomp all of this stuff out.

Chris Lattner b5f8eb8315 Do not loop over uses as we delete them. This causes iterators to be 
invalidated out from under us.  This bug goes back to revision 1.1: scary.
