Bug 175225 – Create a new JavaScript RegExp benchmark

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[Michael Saboff]

The current common JavaScript benchmarks have spotty and outdated coverage of Regular Expression processing performance.  We should create a new benchmark that measures RegExp performance on likely real world web use of ES6 Regular Expressions.  This should include uses of RegExp's for parsing, complicated captured patterns, and use of the unicode flag.

[Michael Saboff]

This patch is big primarily due one large JavaScript data file, waypoints.js used in the FlightPlanner test.

Bugzilla seriously craps itself on this patch! Can't review inline...

Took a glance at what seems important, looks good overall. A few comments then r=me

PerformanceTests/RexBench/about.html

"help compete and win". Always be winning.

“Flight Planner Unicode” should be in Unicode instead!

“ equivolents” typo

PerformanceTests/RexBench/basic_benchmark.js

For some reason Bugzilla isn't letting me leave a comment on the patch, but you have a commented out line like:
//  print("Benchmark   .........

It's probably worth removing.
