2016-10-25[llvm-cov] Add support for loading coverage from multiple objectsVedant Kumar1-11/+11
Differential Revision: https://reviews.llvm.org/D25086 llvm-svn: 285088

2016-07-26Retry: [llvm-cov] Add support for exporting coverage data to JSONVedant Kumar1-0/+29
This enables users to export coverage information as portable JSON for use by analysis tools and storage in document based databases. The export sub-command is invoked just like the others: llvm-cov export -instr-profile path/to/foo.profdata path/to/foo.binary The resulting JSON contains a list of files and functions. Every file object contains a list of segments, expansions, and a summary of the file's region, function, and line coverage. Every function object contains the function's name and regions. There is also a total summary for the entire object file. Changes since the initial commit (r276813): - Fixed the regexes in the tests to handle Windows filepaths. Patch by Eddie Hurtig!

2016-07-20[docs] Fixing Sphinx warnings to unclog the buildbotRenato Golin3-12/+12
Lots of blocks had "llvm" or "nasm" syntax types but either weren't following the syntax, or the syntax has changed (and sphinx hasn't keep up) or the type doesn't even exist (nasm?). Other documents had :options: what were invalid. I only removed those that had warnings, and left the ones that didn't, in order to follow the principle of least surprise. This is like this for ages, but the buildbot is now failing on errors. It may take a while to upgrade the buildbot's sphinx, if that's even possible, but that shouldn't stop us from getting docs updates (which seem down for quite a while). Also, we're not losing any syntax highlight, since when it doesn't parse, it doesn't colour. Ie. those blocks are not being highlighted anyway. I'm trying to get all docs in one go, so that it's easy to revert later if we do fix, or at least easy to know what's to fix. llvm-svn: 276109
2016-07-19Retry: [llvm-profdata] Speed up merging by using a thread poolVedant Kumar1-0/+5
Add a "-j" option to llvm-profdata to control the number of threads used. Auto-detect NumThreads when it isn't specified, and avoid spawning threads when they wouldn't be beneficial. I tested this patch using a raw profile produced by clang (147MB). Here is the time taken to merge 4 copies together on my laptop: No thread pool: 112.87s user 5.92s system 97% cpu 2:01.08 total With 2 threads: 134.99s user 26.54s system 164% cpu 1:33.31 total Changes since the initial commit: - When handling odd-length inputs, call ThreadPool::wait() before merging the last profile. Should fix a race/off-by-one (see r275937). Differential Revision: https://reviews.llvm.org/D22438 llvm-svn: 275938

2016-07-15bugpoint: add flag -verbose-errorsSebastian Pop1-0/+8
The default behavior of bugpoint is to print "<crash>" when it finds a reduced test that crashes compilation. With this flag we now can see the output of the crashing program. This is useful to make sure it is the same error being tracked down and not a different error that happens to crash the compiler as well.

2016-07-15[llvm-cov] Optionally use a symbol demangler when preparing reportsVedant Kumar1-0/+8
Add an option to specify a symbol demangler (as well as options to the demangler). This can be used to make reports more human-readable. This option is especially useful in -output-dir mode, since it isn't as easy to manually pipe reports into a demangler in this mode. llvm-svn: 275640

2016-06-04[llvm-profdata] Revert r271709 and the 3 subsequent commits - the codeChandler Carruth1-9/+0
and/or tests aren't working on Windows currently. There seems to be some problem with quoting the file paths. I don't understand the test structure here or the code well enough to try to come up with a way to correctly handle paths with back slashes in them, and this has caused the Windows builds to be failing for 7 hours now, so I'm reverting the whole thing to bring them back to life. Sorry for the disruption, but a couple of these were bug fixes anyways that can be folded into a fresh commit. Reverts the following patches: r271756: Clean up the way we create the input filenames buffer (NFC) r271748: Fix use-after-free from discarded MemoryBuffer (NFC) r271710: Fix option description (NFC) r271709: Add option to ingest filepaths from a file llvm-svn: 271760

2015-12-15[llvm-profdata] Add support for weighted merge of profile data (2nd try)Nathan Slingerland1-1/+40
Summary: This change adds support for specifying a weight when merging profile data with the llvm-profdata tool. Weights are specified by using the --weighted-input=<weight>,<filename> option. Input files not specified with this option (normal positional list after options) are given a default weight of 1. Adding support for arbitrary weighting of input profile data allows for relative importance to be placed on the input data from multiple training runs. Both sampled and instrumented profiles are supported.

2015-11-09[EABI] Add LLVM support for -meabi flagRenato Golin1-0/+6
"GCC requires the freestanding environment provide memcpy, memmove, memset and memcmp": https://gcc.gnu.org/onlinedocs/gcc-5.2.0/gcc/Standards.html Hence in GNUEABI targets LLVM should not convert 'memops' to their equivalent '__aeabi_memops'. This convertion violates GCC contract. The -meabi flag controls whether or not LLVM will modify 'memops' in GNUEABI targets. Without -meabi: use the triple default EABI. With -meabi=default: use the triple default EABI. With -meabi=gnu: use 'memops'. With -meabi=4 or -meabi=5: use '__aeabi_memops'. With -meabi set to an unknown value: same as -meabi=default.
