2013-03-26PowerPC: Use CCBITRC operand for ISEL patterns.Ulrich Weigand
This commit changes the ISEL patterns to use a CCBITRC operand instead of a "pred" operand. This matches the actual instruction text more directly, and simplifies use of ISEL with the asm parser. In addition, this change allows some simplification of handling the "pred" operand, as this is now only used by BCC. No change in generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178003 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26PowerPC: Simplify BLR pattern.Ulrich Weigand
The BLR pattern cannot be recognized by the asm parser in its current form. This complexity is due to an apparent attempt to enable conditional BLR variants. However, none of those can ever be generated by current code; the pattern is only ever created using the default "pred" operand. To simplify the pattern and allow it to be recognized by the parser, this commit removes those attempts at conditional BLR support. When we later come back to actually add real conditional BLR, this should probably be done via a fully generic conditional branch pattern. No change in generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178002 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26PowerPC: Move some 64-bit branch patterns.Ulrich Weigand
In PPCInstr64Bit.td, some branch patterns appear in a different sequence than the corresponding 32-bit patterns in PPCInstrInfo.td. To simplify future changes that affect both files, this commit moves those patterns to rearrange them into a similar sequence. No effect on generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178001 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-26Fix SCEV forgetMemoizedResults should search and destroy backedge exprs.Andrew Trick
Fixes PR15570: SEGV: SCEV back-edge info invalid after dead code removal. Indvars creates a SCEV expression for the loop's back edge taken count, then determines that the comparison is always true and removes it. When loop-unroll asks for the expression, it contains a NULL SCEVUnknkown (as a CallbackVH). forgetMemoizedResults should invalidate the loop back edges expression. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177986 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26Split out the IRReader header and the utility functions it provides intoChandler Carruth
its own library. These functions are bridging between the bitcode reader and the ll parser which are in different libraries. Previously we didn't have any good library to do this, and instead played fast and loose with a "header only" set of interfaces in the Support library. This really doesn't work well as evidenced by the recent attempt to add timing logic to the these routines. As part of this, make them normal functions rather than weird inline functions, and sink the implementation into the library. Also clean up the header to be nice and minimal. This requires updating lots of build system dependencies to specify that the IRReader library is needed, and several source files to not implicitly rely upon the header file to transitively include all manner of other headers. If you are using IRReader.h, this commit will break you (the header moved) and you'll need to also update your library usage to include 'irreader'. I will commit the corresponding change to Clang momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177971 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-26[ObjCARC Annotations] Added support for displaying the state of pointers at ↵Michael Gottesman
the bottom/top of BBs of the ARC dataflow analysis for both bottomup and topdown analyses. This will allow for verification and analysis of the merge function of the data flow analyses in the ARC optimizer. The actual implementation of this feature is by introducing calls to the functions llvm.arc.annotation.{bottomup,topdown}.{bbstart,bbend} which are only declared. Each such call takes in a pointer to a global with the same name as the pointer whose provenance is being tracked and a pointer whose name is one of our Sequence states and points to a string that contains the same name. To ensure that the optimizer does not consider these annotations in any way, I made it so that the annotations are considered to be of IC_None type. A test case is included for this commit and the previous ObjCARCAnnotation commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177952 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26[ObjCARC Annotations] Implemented ARC annotation metadata to expose the ARC ↵Michael Gottesman
data flow analysis state in the IR via metadata. Previously the inner works of the data flow analysis in ObjCARCOpts was hard to get out of the optimizer for analysis of bugs or testing. All of the current ARC unit tests are based off of testing the effect of the data flow analysis (i.e. what statements are removed or moved, etc.). This creates weakness in the current unit testing regimem since we are not actually testing what effects various instructions have on the modeled pointer state. Additionally in order to analyze a bug in the optimizer, one would need to track by hand what the optimizer was actually doing either through use of DEBUG statements or through the usage of a debugger, both yielding large loses in developer productivity. This patch deals with these two issues by providing ARC annotation metadata that annotates instructions with the state changes that they cause in various pointers as well as provides metadata to annotate provenance sources. Specifically, we introduce the following metadata types: 1. llvm.arc.annotation.bottomup. 2. llvm.arc.annotation.topdown. 3. llvm.arc.annotation.provenancesource. llvm.arc.annotation.{bottomup,topdown}: These annotations describes a state change in a pointer when we are visiting instructions bottomup/topdown respectively. The output format for both is the same: !1 = metadata !{metadata !"(test,%x)", metadata !"S_Release", metadata !"S_Use"} The first element is a string tuple with the following format: (function,variable name) The second two elements of the metadata show the previous state of the pointer (in this case S_Release) and the new state of the pointer (S_Use). We write the metadata in such a manner to ensure that it is easy for outside tools to parse. This is important since I am currently working on a tool for taking this information and pretty printing it besides the IR and that can be used for LIT style testing via the generation of an index. llvm.arc.annotation.provenancesource: This metadata is used to annotate instructions which act as provenance sources, i.e. ones that introduce a new (from the optimizer's perspective) non-argument pointer to track. This enables cross-referencing in between provenance sources and the state changes that occur to them. This is still a work in progress. Additionally I plan on committing later today additions to the annotations that annotate at the top/bottom of basic blocks the state of the various pointers being tracked. *NOTE* The metadata support is conditionally compiled into libObjCARCOpts only when we are producing a debug build of llvm/clang and even so are disabled by default. To enable the annotation metadata, pass in -enable-objc-arc-annotations to opt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177951 91177308-0d34-0410-b5e6-96231b3b80d8
