2017-06-24[SelectionDAG] set dereferenceable flag when expanding memcpy/memmoveupstream-mirrorHiroshi Inoue
When SelectionDAG expands memcpy (or memmove) call into a sequence of load and store instructions, it disregards dereferenceable flag even the source pointer is known to be dereferenceable. This results in an assertion failure if SelectionDAG commonizes a load instruction generated for memcpy with another load instruction for the source pointer. This patch makes SelectionDAG to set the dereferenceable flag for the load instructions properly to avoid the assertion failure.

2017-06-24Ensure backends available in 'opt' are also available in 'bugpoint'Tobias Grosser
This patch links LLVM back-ends into bugpoint the same way they are already available in 'opt' and 'clang'. This resolves an inconsistency that allowed the use of LLVM backends in loadable modules that run in 'opt', but that would prevent the debugging of these modules with bugpoint due to unavailable / unresolved symbols. For e.g. In D31859, Polly requires the NVPTX back-end.

Summary: opt-stats.py and opt-viewer.py's argument parsers both take a positional argument 'yaml_files'. Positional arguments in Python's argparse module are required by default, so the subsequent checks for `len(args.yaml_files) == 0` are unnecessary -- if the length was zero, then the call to `parser.parse_args()` would have thrown an error already. Because there is no way for `len(args.yaml_files)` to be zero at these points, removing the code is NFC.

2017-06-23[AArch64] Prefer Bcc to CBZ/CBNZ/TBZ/TBNZ when NZCV flags can be set for "free".Chad Rosier
This patch contains a pass that transforms CBZ/CBNZ/TBZ/TBNZ instructions into a conditional branch (Bcc), when the NZCV flags can be set for "free". This is preferred on targets that have more flexibility when scheduling Bcc instructions as compared to CBZ/CBNZ/TBZ/TBNZ (assuming all other variables are equal). This can reduce register pressure and is also the default behavior for GCC. A few examples: add w8, w0, w1 -> cmn w0, w1 ; CMN is an alias of ADDS. cbz w8, .LBB_2 -> b.eq .LBB0_2 ; single def/use of w8 removed. add w8, w0, w1 -> adds w8, w0, w1 ; w8 has multiple uses. cbz w8, .LBB1_2 -> b.eq .LBB1_2 sub w8, w0, w1 -> subs w8, w0, w1 ; w8 has multiple uses. tbz w8, #31, .LBB6_2 -> b.ge .LBB6_2 In looking at all current sub-target machine descriptions, this transformation appears to be either positive or neutral.

Commit r306010 adjusted the condition as follows: - if (Is64Bit) { + if (!STI.isTargetWin32()) { The intent was to preserve the behavior on all Windows platforms but extend the behavior on 64-bit Windows platforms to every other one. (Before r306010, emitStackProbeCall only ever executed when emitting code for Windows triples.) Unfortunately, if (Is64Bit && STI.isOSWindows()) is not the same as if (!STI.isTargetWin32()) because of the way isTargetWin32() is defined: bool isTargetWin32() const { return !In64BitMode && (isTargetCygMing() || isTargetKnownWindowsMSVC()); } In practice this broke the JIT tests on 32-bit Windows, which did not satisfy the new condition: LLVM :: ExecutionEngine/MCJIT/2003-01-15-AlignmentTest.ll LLVM :: ExecutionEngine/MCJIT/2003-08-15-AllocaAssertion.ll LLVM :: ExecutionEngine/MCJIT/2003-08-23-RegisterAllocatePhysReg.ll LLVM :: ExecutionEngine/MCJIT/test-loadstore.ll LLVM :: ExecutionEngine/OrcMCJIT/2003-01-15-AlignmentTest.ll LLVM :: ExecutionEngine/OrcMCJIT/2003-08-15-AllocaAssertion.ll LLVM :: ExecutionEngine/OrcMCJIT/2003-08-23-RegisterAllocatePhysReg.ll LLVM :: ExecutionEngine/OrcMCJIT/test-loadstore.ll because %esp was not updated correctly.

2017-06-23[llvm-pdbutil] Add a function for formatting MSF data.Zachary Turner
The goal here is to make it possible to display absolute file offsets when dumping byets from an MSF. The problem is that when dumping bytes from an MSF, often the bytes will cross a block boundary and encounter a discontinuity. We can't use the normal formatBinary() function for this because this would just treat the sequence as entirely ascending, and not account out-of-order blocks. This patch adds a formatMsfData() function to our printer, and then uses this function to improve the output of the -stream-data command line option for dumping bytes from a particular stream. Test coverage is also expanded to make sure to include all possible scenarios of offsets, sizes, and crossing block boundaries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@306141 91177308-0d34-0410-b5e6-96231b3b80d8
