* SelectionDAG: Don't use MVT::Other to determine legality of ISD::SELECT_CCTom Stellard2014-06-101-6/+0
| | | | | | | | | | | | | The SelectionDAG bad a special case for ISD::SELECT_CC, where it would allow targets to specify: setOperationAction(ISD::SELECT_CC, MVT::Other, Expand); to indicate that they wanted to expand ISD::SELECT_CC for all types. This wasn't applied correctly everywhere, and it makes writing new DAG patterns with ISD::SELECT_CC difficult. llvm-svn: 210541
* SelectionDAG: Expand SELECT_CC to SELECT + SETCCTom Stellard2014-06-101-18/+2
| | | | | | | | This consolidates code from the Hexagon, R600, and XCore targets. No functionality change intended. llvm-svn: 210539

* [Modules] Make Support/Debug.h modular. This requires it to not changeChandler Carruth2014-04-211-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | behavior based on other files defining DEBUG_TYPE, which means it cannot define DEBUG_TYPE at all. This is actually better IMO as it forces folks to define relevant DEBUG_TYPEs for their files. However, it requires all files that currently use DEBUG(...) to define a DEBUG_TYPE if they don't already. I've updated all such files in LLVM and will do the same for other upstream projects. This still leaves one important change in how LLVM uses the DEBUG_TYPE macro going forward: we need to only define the macro *after* header files have been #include-ed. Previously, this wasn't possible because Debug.h required the macro to be pre-defined. This commit removes that. By defining DEBUG_TYPE after the includes two things are fixed: - Header files that need to provide a DEBUG_TYPE for some inline code can do so by defining the macro before their inline code and undef-ing it afterward so the macro does not escape. - We no longer have rampant ODR violations due to including headers with different DEBUG_TYPE definitions. This may be mostly an academic violation today, but with modules these types of violations are easy to check for and potentially very relevant. Where necessary to suppor headers with DEBUG_TYPE, I have moved the definitions below the includes in this commit. I plan to move the rest of the DEBUG_TYPE macros in LLVM in subsequent commits; this one is big enough. The comments in Debug.h, which were hilariously out of date already, have been updated to reflect the recommended practice going forward. llvm-svn: 206822

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change came about primarily because of two issues in the existing code. Niether of: define i64 @test1(i64 %val) { %in = trunc i64 %val to i32 tail call i32 @ret32(i32 returned %in) ret i64 %val } define i64 @test2(i64 %val) { tail call i32 @ret32(i32 returned undef) ret i32 42 } should be tail calls, and the function sameNoopInput is responsible. The main problem is that it is completely symmetric in the "tail call" and "ret" value, but in reality different things are allowed on each side. For these cases: 1. Any truncation should lead to a larger value being generated by "tail call" than needed by "ret". 2. Undef should only be allowed as a source for ret, not as a result of the call. Along the way I noticed that a mismatch between what this function treats as a valid truncation and what the backends see can lead to invalid calls as well (see x86-32 test case). This patch refactors the code so that instead of being based primarily on values which it recurses into when necessary, it starts by inspecting the type and considers each fundamental slot that the backend will see in turn. For example, given a pathological function that returned {{}, {{}, i32, {}}, i32} we would consider each "real" i32 in turn, and ask if it passes through unchanged. This is much closer to what the backend sees as a result of ComputeValueVTs. Aside from the bug fixes, this eliminates the recursion that's going on and, I believe, makes the bulk of the code significantly easier to understand. The trade-off is the nasty iterators needed to find the real types inside a returned value. llvm-svn: 187787

| | | | | | | | | | | | | | | | | | conditions are met: 1. They share the same operand and are in the same BB. 2. Both outputs are used. 3. The target has a native instruction that maps to ISD::FSINCOS node or the target provides a sincos library call. Implemented the generic optimization in sdisel and enabled it for Mac OSX. Also added an additional optimization for x86_64 Mac OSX by using an alternative entry point __sincos_stret which returns the two results in xmm0 / xmm1. rdar://13087969 PR13204 llvm-svn: 173755

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-7/+7
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. llvm-svn: 171366
* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-8/+8
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131

* TargetLowering interface to set/get minimum block entries for jump tables.Sebastian Pop2012-09-251-0/+2
| | | | | | | | | | | | | | Provide interface in TargetLowering to set or get the minimum number of basic blocks whereby jump tables are generated for switch statements rather than an if sequence. getMinimumJumpTableEntries() defaults to 4. setMinimumJumpTableEntries() allows target configuration. This patch changes the default for the Hexagon architecture to 5 as it improves performance on some benchmarks. llvm-svn: 164628
