2006-05-31Swap the order of operands created here. For +&|^, the order doesn't matter,Chris Lattner

2006-05-30Provide a simpler interface for getting a ConstantArray from a characterReid Spencer
string. Instead of specifying the length, just specify whether the user wants a terminating null or not. The default is "true" to retain the same behavior as previously provided by this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28562 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-30Undo a patch that breaks llvm-as because the warning message is written toReid Spencer
stdout when the output of llvm-as is also written to stdout. We'll have to fix tcl some other way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28557 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-30Write the WARNING message to cout instead of cerr. Writing to cerr causesReid Spencer
Tcl to claim that the program had an error and thus produces errors in the dejagnu testing when its really just a warning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28556 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-30Adjust the interface to ConstantArray::get. The previousReid Spencer
implementation always added a null byte to the end of the string. It turns out that this is not always wanted. By adding a length parameter we preserve this behavior when length==0 (default value) but also allow other lengths (not null terminated) to be created. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28552 91177308-0d34-0410-b5e6-96231b3b80d8

Fold c2 in (x << c1) | c2 where (c2 < c1) e.g. int test(int x) { return (x << 3) + 7; } This can be codegen'd as: leal 7(,%eax,8), %eax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28550 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-29Since there was interest on the mailing list, this is a utility pass thatAndrew Lenharth
uses DSA to make find targets of calls. It provides a very convinient interface to DSA results to do things with indirect calls, such as write a devirtualizer (which I have and may commit one of these days). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28545 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-29Add Use replacement. Assuming there is nothing horribly wrong with this, LCSSAOwen Anderson
is now theoretically feature-complete. It has not, however, been thoroughly test, and is still considered experimental. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28529 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-28Major think-o. Iterate over all live out-of-loop values, and perform theOwen Anderson
other calculations on each individually, rather than trying to delay it and do them all at the end. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28527 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-27Make LCSSA insert proper Phi nodes throughout the rest of the CFG by computingOwen Anderson
the iterated Dominance Frontier of the loop-closure Phi's. This is the second phase of the LCSSA pass. The third phase (coming soon) will be to update all uses of loop variables to use the loop-closure Phi's instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28524 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-27Fix some regression from the inliner patch I committed last night. This fixesChris Lattner
ldecod, lencod, and SPASS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28523 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-27Switch the inliner over to using CloneAndPruneFunctionInto. This effectivelyChris Lattner
makes it so that it constant folds instructions on the fly. This is good for several reasons: 0. Many instructions are constant foldable after inlining, particularly if inlining a call with constant arguments. 1. Without this, the inliner has to allocate memory for all of the instructions that can be constant folded, then a subsequent pass has to delete them. This gets the job done without this extra work. 2. This makes the inliner *pass* a bit more aggressive: in particular, it partially solves a phase order issue where the inliner would inline lots of code that folds away to nothing, but think that the resultant function is big because of this code that will be gone. Now the code never exists. This is the first part of a 2-step process. The second part will be smart enough to see when this implicit constant folding propagates a constant into a branch or switch instruction, making CFG edges dead. This implements Transforms/Inline/inline_constprop.ll git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28521 91177308-0d34-0410-b5e6-96231b3b80d8

given it's opcode, typeand operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28517 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-27Fix a nasty dag combiner bug that caused nondeterminstic crashes (MY FAVORITE!):Chris Lattner
SimplifySelectOps would eliminate a Select, delete it, then return true. The clients would see that it did something and return null. The top level would see a null return, and decide that nothing happened, proceeding to process the node in other ways: boom. The fix is simple: clients of SimplifySelectOps should return the select node itself. In order to catch really obnoxious boogs like this in the future, add an assert that nodes are not deleted. We do this by checking for a sentry node type that the SDNode dtor sets when a node is destroyed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28514 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-26Make CALL node consistent with RET node. Signness of value has type MVT::i32Evan Cheng
instead of MVT::i1. Either is fine except MVT::i32 is probably a legal type for most (if not all) platforms while MVT::i1 is not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28511 91177308-0d34-0410-b5e6-96231b3b80d8
