* Remove unnecessary code.Evan Cheng2013-02-111-4/+0

* Revert 172027 and 174336. Remove diagnostics about over-aligned stack objects.Bob Wilson2013-02-081-2/+1
| | | | | | | | | | | | Aside from the question of whether we report a warning or an error when we can't satisfy a requested stack object alignment, the current implementation of this is not good. We're not providing any source location in the diagnostics and the current warning is not connected to any warning group so you can't control it. We could improve the source location somewhat, but we can do a much better job if this check is implemented in the front-end, so let's do that instead. <rdar://problem/13127907> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174741 91177308-0d34-0410-b5e6-96231b3b80d8

* Make APFloat constructor require explicit semantics.Tim Northover2013-01-221-1/+2
| | | | | | | | | Previously we tried to infer it from the bit width size, with an added IsIEEE argument for the PPC/IEEE 128-bit case, which had a default value.

* Stack Alignment: throw error if we can't satisfy the minimal alignmentManman Ren2013-01-101-1/+2
| | | | | | | | | | | | | | | | | | | requirement when creating stack objects in MachineFrameInfo. Add CreateStackObjectWithMinAlign to throw error when the minimal alignment can't be achieved and to clamp the alignment when the preferred alignment can't be achieved. Same is true for CreateVariableSizedObject. Will not emit error in CreateSpillStackObject or CreateStackObject. As long as callers of CreateStackObject do not assume the object will be aligned at the requested alignment, we should not have miscompile since later optimizations which look at the object's alignment will have the correct information. rdar://12713765 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172027 91177308-0d34-0410-b5e6-96231b3b80d8
* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-021-13/+13
| | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

* Fall back to the selection dag isel to select tail calls.Chad Rosier2012-12-111-5/+0
| | | | | | | | | | | | | | | | | | | This shouldn't affect codegen for -O0 compiles as tail call markers are not emitted in unoptimized compiles. Testing with the external/internal nightly test suite reveals no change in compile time performance. Testing with -O1, -O2 and -O3 with fast-isel enabled did not cause any compile-time or execution-time failures. All tests were performed on my x86 machine. I'll monitor our arm testers to ensure no regressions occur there. In an upcoming clang patch I will be marking the objc_autoreleaseReturnValue and objc_retainAutoreleaseReturnValue as tail calls unconditionally. While it's theoretically true that this is just an optimization, it's an optimization that we very much want to happen even at -O0, or else ARC applications become substantially harder to debug.

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-20/+20
| | | | | | | | | | | | | | | | | 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. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | __builtin_debugtrap() which is supposed to consistently raise SIGTRAP across all systems. In contrast, __builtin_trap() behave differently on different systems. e.g. it raises SIGTRAP on ARM, and SIGILL on X86. The purpose of __builtin_debugtrap() is to consistently provide "trap" functionality, in the mean time preserve the compatibility with on gcc on __builtin_trap(). The X86 backend is already able to handle debugtrap(). This patch is to: 1) make front-end recognize "__builtin_debugtrap()" (emboddied in the one-line change to Clang). 2) In DAG legalization phase, by default, "debugtrap" will be replaced with "trap", which make the __builtin_debugtrap() "available" to all existing ports without the hassle of changing their code. 3) If trap-function is specified (via -trap-func=xyz to llc), both __builtin_debugtrap() and __builtin_trap() will be expanded into the function call of the specified trap function. This behavior may need change in the future. The provided testing-case is to make sure 2) and 3) are working for ARM port, and we already have a testing case for x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166300 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | SchedulerDAGInstrs::buildSchedGraph ignores dependencies between FixedStack objects and byval parameters. So loading byval parameters from stack may be inserted *before* it will be stored, since these operations are treated as independent. Fix: Currently ARMTargetLowering::LowerFormalArguments saves byval registers with FixedStack MachinePointerInfo. To fix the problem we need to store byval registers with MachinePointerInfo referenced to first the "byval" parameter. Also commit adds two new fields to the InputArg structure: Function's argument index and InputArg's part offset in bytes relative to the start position of Function's argument. E.g.: If function's argument is 128 bit width and it was splitted onto 32 bit regs, then we got 4 InputArg structs with same arg index, but different offset values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165616 91177308-0d34-0410-b5e6-96231b3b80d8
