I'm starting working to fix JIT support of BigInt in some operations
we already have upstream. In such case, I'm sending
(https://bugs.webkit.org/show_bug.cgi?id=186177) to support BigInt
speculation into ValueAdd node. As I want to know if BigInt
speculation represents some performance improvement, I'm also
proposing a new benchmark suite called BigIntBench. The idea right now
is to enable us to write microbenchmarks while working into JIT fixes.
The main reason behind that is due the practicality of enabling
"--useBigInt=true" flags for tests in this suite. The big plan is to
move all microbenchmarks to "JSTests/microbenchmarks" and then add
relevant tests to evaluate how fast JSC can manipulate BigInts. IIRC,
Robin Morisset mentioned about introducing some benchmarks to evaluate
BigInt implementation sometime ago.
What do you think about that? Does it make sense?
