Trivial changes since v1, but I wanted to send a new one for completeness since I re-sent the "Easy to review grep & pre-PCRE changes" series. For v1 see <20170511170142.15934-1-avarab@xxxxxxxxx> (https://public-inbox.org/git/20170511170142.15934-1-avarab@xxxxxxxxx/). Changes noted below & reply to who noted the issue: Ævar Arnfjörð Bjarmason (7): grep: don't redundantly compile throwaway patterns under threading Brandon: Added a few paragraphs to the commit message about why this change is being made, i.e. for ease of understanding the code, not optimization. grep: skip pthreads overhead when using one thread log: add -P as a synonym for --perl-regexp grep: add support for the PCRE v1 JIT API grep: un-break building with PCRE < 8.32 grep: un-break building with PCRE < 8.20 grep: add support for PCRE v2 No changes in these, except for re-running the performance tests & changing the commit messages accordingly, due to the change in the t/perf code in the previous series, as noted there.
