* [ADT] Zip range adapterMehdi Amini2016-10-192-0/+152
| | | | | | | | | | | | | | | This augments the STLExtras toolset with a zip iterator and range adapter. Zip comes in two varieties: `zip`, which will zip to the shortest of the input ranges, and `zip_first`, which limits its `begin() == end()` checks to just the first range.

* [llvm-cov] Don't spawn a thread unless ThreadCount > 1Vedant Kumar2016-10-191-27/+39
| | | | | | | | | | | | Initializing a ThreadPool with ThreadCount = 1 spawns a thread even though we don't need to. This is at least slower than it needs to be, and at worst may somehow be exacerbating PR30735 (llvm-cov times out on ARM bots). As a follow-up, I'll try to add logic to llvm::ThreadPool to avoid spawning a thread when ThreadCount = 1. llvm-svn: 284621
* [mips][msa] Range check MSA intrinsics with immediatesSimon Dardis2016-10-195-56/+671
| | | | | | | | | | | | | | | | This patch teaches clang to range check immediates for MIPS MSA instrinsics. This checking is done strictly in comparison to some existing GCC implementations. E.g. msa_andvi_b(var, 257) does not result in andvi $wX, 1. Similarily msa_ldi_b takes a range of -128 to 127. As part of this effort, correct the existing MSA test as it has both illegal types and immediates. Reviewers: vkalintiris Differential Revision: https://reviews.llvm.org/D25017 llvm-svn: 284620

* Minidump plugin: functions parsing memory structures and filtering module listDimitar Vlahovski2016-10-198-2/+464
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Now the Minidump parser can parse the: 1) MemoryInfoList - containing region info about memory ranges (readable, writable, executable) 2) Memory64List - this is the stuct used when the Minidump is a full-memory one. 3) Adding filtering of the module list (shared libraries list) - there can be mutliple records in the module list under the same name but with different load address (e.g. when the binary has non contigious sections). FilterModuleList eliminates the duplicated modules, leaving the one with the lowest load addr. Added unit tests for everything.

* Add Chrono.h - std::chrono support headerPavel Labath2016-10-1910-124/+212
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: std::chrono mostly covers the functionality of llvm::sys::TimeValue and lldb_private::TimeValue. This header adds a bit of utility functions and typedefs, which make the usage of the library and porting code from TimeValues easier. Rationale: - TimePoint typedef - precision of system_clock is implementation defined - using a well-defined precision helps maintain consistency between platforms, makes it interact better with existing TimeValue classes, and avoids cases there a time point is implicitly convertible to a specific precision on some platforms but not on others. - system_clock::to_time_t only accepts time_points with the default system precision (even though time_t has only second precision on all platforms we support). To avoid the need for explicit casts, I have added a toTimeT() wrapper function. toTimePoint(time_t) was not strictly necessary, but I have added it for symmetry.

* [SystemZ] Add missing vector instructions for the assemblerUlrich Weigand2016-10-195-18/+3237
| | | | | | | | | | | | | | | | | | | | | | Most z13 vector instructions have a base form where the data type of the operation (whether to consider the vector to be 16 bytes, 8 halfwords, 4 words, or 2 doublewords) is encoded into a mask field, and then a set of extended mnemonics where the mask field is not present but the data type is encoded into the mnemonic name. Currently, LLVM only supports the type-specific forms (since those are really the ones needed for code generation), but not the base type-generic forms. To complete the assembler support and make it fully compatible with the GNU assembler, this commit adds assembler aliases for all the base forms of the various vector instructions. It also adds two more alias forms that are documented in the PoP: VFPSO/VFPSODB/WFPSODB -- generic form of VFLCDB etc. VNOT -- special variant of VNO llvm-svn: 284586
* [SystemZ] Add optional argument to some vector string instructionsUlrich Weigand2016-10-195-175/+566
| | | | | | | | | | | | The vfee[bhf], vfene[bhf], and vistr[bhf] assembler mnemonics are documented in the Principles of Operation to have an optional last operand to encode arbitrary values in a mask field. This commit adds support for those optional operands, and cleans up the patterns to generate vector string instruction as bit. No change to code generation intended. llvm-svn: 284585

* [cmake] Declare LLVM_CMAKE_PATH for use in subprojectsMichal Gorny2016-10-192-1/+3
| | | | | | | | | | | | | | | | | | | Declare the LLVM_CMAKE_PATH to the source directory location of CMake files, in order to make it possible to easily use them in subprojects. Such a variable is already declared in most of LLVM projects (and inconsistently mixed with direct source tree references), including Clang, LLDB, compiler-rt, libcxx... Declaring it inside main LLVM tree makes it possible to avoid having to declare fallback values or use conditionals in those projects. It should be noted that in some of the subprojects LLVM_CMAKE_PATH is used to reference generated LLVMConfig.cmake file. However, these references are conditional to stand-alone builds and explicitly including this file is unnecessary in combined builds.

* [Thumb-1] Synthesize TBB/TBH instructions to make use of compressed jump tablesJames Molloy2016-10-198-37/+262
| | | | | | | | | | | | | | | | | | | | | | | | | | The TBB and TBH instructions in Thumb-2 allow jump tables to be compressed into sequences of bytes or shorts respectively. These instructions do not exist in Thumb-1, however it is possible to synthesize them out of a sequence of other instructions. It turns out this sequence is so short that it's almost never a lose for performance and is ALWAYS a significant win for code size. TBB example: Before: lsls r0, r0, #2 After: add r0, pc adr r1, .LJTI0_0 ldrb r0, [r0, #6] ldr r0, [r0, r1] lsls r0, r0, #1 mov pc, r0 add pc, r0 => No change in prologue code size or dynamic instruction count. Jump table shrunk by a factor of 4. The only case that can increase dynamic instruction count is the TBH case: Before: lsls r0, r4, #2 After: lsls r4, r4, #1 adr r1, .LJTI0_0 add r4, pc ldr r0, [r0, r1] ldrh r4, [r4, #6] mov pc, r0 lsls r4, r4, #1 add pc, r4 => 1 more instruction in prologue. Jump table shrunk by a factor of 2. So there is an argument that this should be disabled when optimizing for performance (and a TBH needs to be generated). I'm not so sure about that in practice, because on small cores with Thumb-1 performance is often tied to code size. But I'm willing to turn it off when optimizing for performance if people want (also note that TBHs are fairly rare in practice!) llvm-svn: 284580
