* ProfileData: Add support for the indexed instrprof formatJustin Bogner2014-04-1810-35/+377
| | | | | | | | This adds support for an indexed instrumentation based profiling format, which is just a small header and an on disk hash table. This format will be used by clang's -fprofile-instr-use= for PGO. llvm-svn: 206656
* Added Sphinx documentation generation to CMake build system.Reid Kleckner2014-04-185-1/+106
| | | | | | | | | | | | | | | | | | | | | The option LLVM_ENABLE_SPHINX option enables the "docs-llvm-html", "docs-llvm-man" targets but does not build them by default. The following CMake options have been added that control what targets are made available SPHINX_OUTPUT_HTML SPHINX_OUTPUT_MAN If LLVM_BUILD_DOCS is enabled then the enabled docs-llvm-* targets will be built by default and if ``make install`` is run then docs-llvm-html and docs-llvm-man will be installed (tested on Linux only). The add_sphinx_target function is in its own file so it can be included by other projects that use Sphinx for their documentation. Patch by Daniel Liew <daniel.liew@imperial.ac.uk>! llvm-svn: 206655
* [DWARF parser] Turn DILineInfo into a struct.Alexey Samsonov2014-04-186-95/+65
| | | | | | | | | | Immutable DILineInfo doesn't bring any benefits and complicates code. Also, use std::string instead of SmallString<16> for file and function names - their length can vary significantly. No functionality change. llvm-svn: 206654
* Update the fragments of symbols in compressed sections.David Blaikie2014-04-182-1/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While unnamed relocations are already cached in side tables in ELFObjectWriter::RecordRelocation, symbols still need their fragments updated to refer to the newly compressed fragment (even if that fragment isn't big enough to fit the offset). Even though we only create temporary symbols in debug info sections this comes up in 32 bit builds where even temporary symbols in mergeable sections (such as debug_str) have to be emitted as named symbols. I tried a few other ways to do this but they all didn't work for various reasons: 1) Canonicalize the MCSymbolData in RecordRelocation, nulling out the Fragment (so it didn't have to be updated by CompressDebugSection). This doesn't work because some code relies on symbols having fragments to indicate that they're defined, I think. 2) Canonicalize the MCSymbolData in RecordRelocation to be "first fragment + absolute offset" so it would be cheaper to just test and update the fragment in CompressDebugSections. This doesn't work because the offset computed in RecordRelocation isn't that of the symbol's fragment, it's the passed in fragment (I haven't figured out what that fragment is - perhaps it's the location where the relocation is to be written). And if the fragment offset has to be computed only for this use we might as well just do it when we need to, in CompressDebugSection. I also added an assert to help catch this a bit more clearly, even though it is UB. The test case improvements would either assert fail and/or valgrind vail without the fix, even if they wouldn't necessarily fail the FileCheck output. llvm-svn: 206653
* [ARM64] Ports the Cortex-A53 Machine Model description from AArch64.Chad Rosier2014-04-184-4/+247
| | | | | | | | | | | | | Summary: This port includes the rudimentary latencies that were provided for the Cortex-A53 Machine Model in the AArch64 backend. It also changes the SchedAlias for COPY in the Cyclone model to an explicit WriteRes mapping to avoid conflicts in other subtargets.

* [PECOFF] Win64 DLL entry function name is _DllMainCRTStartup.Rui Ueyama2014-04-182-4/+17
| | | | | | Unlike Win32/x86, it has no "@12" suffix. llvm-svn: 206648
* [PECOFF] Support LIBRARY directive.Rui Ueyama2014-04-184-1/+34
| | | | | | | LIBRARY directive in a module definition file specifies the output DLL file name. It also takes an optional value for the base address. llvm-svn: 206647
* [LCG] Fix the bugs that Ben pointed out in code review (and the MSan botChandler Carruth2014-04-181-3/+7

* Don't read CompilerInstance fields that don't exist in ASTUnitBen Langmuir2014-04-181-3/+6
| | | | | | | When transferring data from a CompilerInstance in an error path we need to consider cases where the various fields are uninitialized. llvm-svn: 206644
* OnDiskHashTable: Expect the Info type to declare the offset typeJustin Bogner2014-04-181-42/+54
| | | | | | | | This changes the on-disk hash to get the type to use for offsets from the Info type, so that clients can be more flexible with the size of table they support. llvm-svn: 206643
* OnDiskHashTable: Expect the Info type to declare the hash sizeJustin Bogner2014-04-181-10/+15
| | | | | | | | This changes the on-disk hash to get the size of a hash value from the Info type, so that clients can be more flexible with the types of hash they use. llvm-svn: 206642
* [DWARF parser] Respect address ranges specified in compile unit DIE.Alexey Samsonov2014-04-181-0/+7
| | | | | | | | | | | When address ranges for compile unit are specified in compile unit DIE itself, there is no need to collect ranges from children subprogram DIEs. This change speeds up llvm-symbolizer on Clang-produced binaries with full debug info. For instance, symbolizing a first address in a 1Gb binary is now 2x faster (1s vs. 2s). llvm-svn: 206641
* Teach users of OnDiskHashTable to define hash_value and offset typesJustin Bogner2014-04-185-22/+52
| | | | | | | | This paves the way to making OnDiskHashTable work with hashes that are not 32 bits wide and to making OnDiskHashTable work very large hash tables. The LLVM change to use these types is upcoming. llvm-svn: 206640

* [X86] Improve buildFromShuffleMostly for AVXAdam Nemet2014-04-182-6/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a 256-bit BUILD_VECTOR consisting mostly of shuffles of 256-bit vectors, both the BUILD_VECTOR and its operands may need to be legalized in multiple steps. Consider: (v8f32 (BUILD_VECTOR (extract_vector_elt (v8f32 %vreg0,) Constant<1>), (extract_vector_elt %vreg0, Constant<2>), (extract_vector_elt %vreg0, Constant<3>), (extract_vector_elt %vreg0, Constant<4>), (extract_vector_elt %vreg0, Constant<5>), (extract_vector_elt %vreg0, Constant<6>), (extract_vector_elt %vreg0, Constant<7>), %vreg1)) a. We can't build a 256-bit vector efficiently so, we need to split it into two 128-bit vecs and combine them with VINSERTX128. b. Operands like (extract_vector_elt (v8f32 %vreg0), Constant<7>) needs to be split into a VEXTRACTX128 and a further extract_vector_elt from the resulting 128-bit vector. c. The extract_vector_elt from b. is lowered into a shuffle to the first element and a movss. Depending on the order in which we legalize the BUILD_VECTOR and its operands[1], buildFromShuffleMostly may be faced with: (v4f32 (BUILD_VECTOR (extract_vector_elt (vector_shuffle<1,u,u,u> (extract_subvector %vreg0, Constant<4>), undef), Constant<0>), (extract_vector_elt (vector_shuffle<2,u,u,u> (extract_subvector %vreg0, Constant<4>), undef), Constant<0>), (extract_vector_elt (vector_shuffle<3,u,u,u> (extract_subvector %vreg0, Constant<4>), undef), Constant<0>), %vreg1)) In order to figure out the underlying vector and their identity we need to see through the shuffles. [1] Note that the order in which operations and their operands are legalized is only guaranteed in the first iteration of LegalizeDAG. Fixes <rdar://problem/16296956> llvm-svn: 206634
* [PECOFF] Support /manifestuac:NO.Rui Ueyama2014-04-183-23/+39

| | | | | | | | | This reverts commit r206622 and the MSVC fixup in r206626. Apparently the remotely failing tests are still failing, despite my attempt to fix the nondeterminism in r206621. llvm-svn: 206628

| | | | | | | | | | Add a helper method to get address ranges specified in a DIE (either by DW_AT_low_pc/DW_AT_high_pc, or by DW_AT_ranges). Use it to untangle and simplify the code. No functionality change. llvm-svn: 206624

* Reapply "blockfreq: Rewrite BlockFrequencyInfoImpl"Duncan P. N. Exon Smith2014-04-1812-316/+3101
| | | | | | | | | | | | | | This reverts commit r206556, effectively reapplying commit r206548 and its fixups in r206549 and r206550. In an intervening commit I've added target triples to the tests that were failing remotely [1] (but passing locally). I'm hoping the mystery is solved? I'll revert this again if the tests are still failing remotely. [1]: http://bb.pgr.jp/builders/ninja-x64-msvc-RA-centos6/builds/1816 llvm-svn: 206622
* Add some target triples for better determinismDuncan P. N. Exon Smith2014-04-182-1/+4
| | | | | | | | | These tests were failing on some buildbots after r206548 (reverted in r206556), but passing locally. They were missing target triples, so maybe that's the problem? llvm-svn: 206621
