* Re-sort #include lines for unittests. This uses a slightly modifiedChandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | clang-format (https://reviews.llvm.org/D33932) to keep primary headers at the top and handle new utility headers like 'gmock' consistently with other utility headers. No other change was made. I did no manual edits, all of this is clang-format. This should allow other changes to have more clear and focused diffs, and is especially motivated by moving some headers into more focused libraries. llvm-svn: 304786
* Support escaping in TrigramIndex.Ivan Krasin2016-12-021-2/+22
| | | | | | | | | | | | | | | | | | Summary: This is a follow up to r288303, where I have introduced TrigramIndex to speed up SpecialCaseList for the cases when all rules are simple wildcards, like *hello*wor.d*. Here, I add support for escaping, so that it's possible to specify rules like *c\+\+abi*.

* Use trigrams to speed up SpecialCaseList.Ivan Krasin2016-12-011-0/+112
Summary: it's often the case when the rules in the SpecialCaseList are of the form hel.o*bar. That gives us a chance to build trigram index to quickly discard 99% of inputs without running a full regex. A similar idea was used in Google Code Search as described in the blog post: https://swtch.com/~rsc/regexp/regexp4.html The check is defeated, if there's at least one regex more complicated than that. In this case, all inputs will go through the regex. That said, the real-world rules are often simple or can be simplied. That considerably speeds up compiling Chromium with CFI and UBSan. As measured on Chromium's content_message_generator.cc: before, CFI: 44 s after, CFI: 23 s after, CFI, no blacklist: 23 s (~1% slower, but 3 runs were unable to show the difference) after, regular compilation to bitcode: 23 s Reviewers: pcc Subscribers: mgorny, llvm-commits Differential Revision: https://reviews.llvm.org/D27188 llvm-svn: 288303
