* [Driver] Add -fdiagnostics-hotness-thresholdBrian Gesiak2017-07-011-7/+33
| | | | | | | | | | | | | | | | | | | | | | | | Summary: Depends on https://reviews.llvm.org/D34867. Add a Clang frontend option to enable optimization remark hotness thresholds, which were added to LLVM in https://reviews.llvm.org/D34867. This prevents diagnostics that do not meet a minimum hotness threshold from being output. When generating optimization remarks for large codebases with a ton of cold code paths, this option can be used to limit the optimization remark output at a reasonable size.

| | | | | | | | | | | | | | This is useful when an upper limit on the cache size needs to be controlled independently of the amount of the amount of free space. One use case is a machine with a large number of cache directories (e.g. a buildbot slave hosting a large number of independent build jobs). By imposing an upper size limit on each cache directory, users can more easily estimate the server's capacity.

* Support lazy stat'ing of files referenced by module maps.Richard Smith2017-06-021-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for a `header` declaration in a module map to specify certain `stat` information (currently, size and mtime) about that header file. This has two purposes: - It removes the need to eagerly `stat` every file referenced by a module map. Instead, we track a list of unresolved header files with each size / mtime (actually, for simplicity, we track submodules with such headers), and when attempting to look up a header file based on a `FileEntry`, we check if there are any unresolved header directives with that `FileEntry`'s size / mtime and perform deferred `stat`s if so. - It permits a preprocessed module to be compiled without the original files being present on disk. The only reason we used to need those files was to get the `stat` information in order to do header -> module lookups when using the module. If we're provided with the `stat` information in the preprocessed module, we can avoid requiring the files to exist. Unlike most `header` directives, if a `header` directive with `stat` information has no corresponding on-disk file the enclosing module is *not* marked unavailable (so that behavior is consistent regardless of whether we've resolved a header directive, and so that preprocessed modules don't get marked unavailable). We could actually do this for all `header` directives: the only reason we mark the module unavailable if headers are missing is to give a diagnostic slightly earlier (rather than waiting until we actually try to build the module / load and validate its .pcm file).

* [ubsan] Add a check for pointer overflow UBVedant Kumar2017-06-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check pointer arithmetic for overflow. For some more background on this check, see: https://wdtz.org/catching-pointer-overflow-bugs.html https://reviews.llvm.org/D20322 Patch by Will Dietz and John Regehr! This version of the patch is different from the original in a few ways: - It introduces the EmitCheckedInBoundsGEP utility which inserts checks when the pointer overflow check is enabled. - It does some constant-folding to reduce instrumentation overhead. - It does not check some GEPs in CGExprCXX. I'm not sure that inserting checks here, or in CGClass, would catch many bugs. Possible future directions for this check: - Introduce CGF.EmitCheckedStructGEP, to detect overflows when accessing structures. Testing: Apart from the added lit test, I ran check-llvm and check-clang with a stage2, ubsan-instrumented clang. Will and John have also done extensive testing on numerous open source projects.
