      [regexp] Shortcut case-folding of entire non-bmp range · 4735f85f
      jgruber authored 
      When the range of all non-bmp characters is passed to
AddUnicodeCaseEquivalents, icu::UnicodeSet::closeOver dutifully tries to
case-fold every single character in that range. Since we already know
this to be a nop, we can simply return instead.

This improves compilation time of /ui regexps by around 100x.

      [regexp] Limit ATOM regexps to patterns length <= 2 · 10817205
      jgruber authored 
      This is a modified reland of 062bb7d4

There's an inherent trade-off when deciding between ATOM and IRREGEXP
regexps: IRREGEXP is faster at runtime for all but trivial short
patterns, while ATOM regexps have a lower memory overhead.

This CL is intended to help investigate impact on benchmarks and real-world
code - if something tanks, it's easy to revert, otherwise it can be a first
step towards a possible removal of ATOM regexps.

      PPC/s390: [compiler] Delay allocation of code-embedded heap numbers. · ae947e26
      sampsong authored 
      Port 659e8f7b

Original Commit Message:

    Instead of allocating and embedding certain heap numbers into the code
    during code assembly, emit dummies but record the allocation requests.
    Later then, in Assembler::GetCode, allocate the heap numbers and patch
    the code by replacing the dummies with the actual objects. The
    RelocInfos for the embedded objects are already recorded correctly when
    emitting the dummies.
