| | | | | | | | If we fold three constants together (c1+c2+c3), make sure to keep LHSC updated, instead of reusing (in this case), the 1 instead of the partial sum. llvm-svn: 20337

| | | | | | | | Actually teach dsa about select instructions. This doesn't affect the graph in any way other than not setting a spurious U marker on pointer nodes that are selected. llvm-svn: 20324

| | | | | | | | | X = gep null, ... Used to not create a scalar map entry for X, which caused clients to barf. This is bad. llvm-svn: 20316

* Implement Transforms/SimplifyCFG/switch_thread.llChris Lattner2005-02-241-4/+190
| | | | | | | | This does a simple form of "jump threading", which eliminates CFG edges that are provably dead. This triggers 90 times in the external tests, and eliminating CFG edges is always always a good thing! :) llvm-svn: 20300

* Fix a bug in the 'store fpimm, ptr' -> 'store intimm, ptr' handling code.Chris Lattner2005-02-221-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changing 'op' here caused us to not enter the store into a map, causing reemission of the code!! In practice, a simple loop like this: no_exit: ; preds = %no_exit, %entry %indvar = phi uint [ %indvar.next, %no_exit ], [ 0, %entry ] ; <uint> [#uses=3] %tmp.4 = getelementptr "complex long double"* %P, uint %indvar, uint 0 ; <double*> [#uses=1] store double 0.000000e+00, double* %tmp.4 %indvar.next = add uint %indvar, 1 ; <uint> [#uses=2] %exitcond = seteq uint %indvar.next, %N ; <bool> [#uses=1] br bool %exitcond, label %return, label %no_exit was being code gen'd to: .LBBtest_1: # no_exit movl %edx, %esi shll $4, %esi movl $0, 4(%eax,%esi) movl $0, (%eax,%esi) incl %edx movl $0, (%eax,%esi) movl $0, 4(%eax,%esi) cmpl %ecx, %edx jne .LBBtest_1 # no_exit Note that we are doing 4 32-bit stores instead of 2. Now we generate: .LBBtest_1: # no_exit movl %edx, %esi incl %esi shll $4, %edx movl $0, (%eax,%edx) movl $0, 4(%eax,%edx) cmpl %ecx, %esi movl %esi, %edx jne .LBBtest_1 # no_exit This is much happier, though it would be even better if the increment of ESI was scheduled after the compare :-/ llvm-svn: 20265
