Hi!

I reviewed the one at https://github.com/tarantool/luajit/commit/2cdd5ac0367629d2f37489dd842d9a6b068cf12c

Overall is LGTM, I would like to update the 2nd test message to something like
’trace should not appear due to maxirconst limit’

Minor: I'd rather move this part closer to 'jit.opt.start' to save the
test structure closer to the other test chunks. Feel free to ignore.

I really want to exclude __any__ JIT work here to avoid false-positive
hotcount (was precendents during writing this test :)). Ignoring.

OK, got it.

+test:ok(ntrace_old + 1 == misc.getmetrics().jit_trace_num,
+ 'trace number increases')

Typo: I doubt we use tabs in Lua sources, but I might be wrong...

I suggest to use quarter tabs indent style as we use for C code and Mike
use in src/jit/*.lua (see bcsave.lua for example).

There was no precedent before, IINM :).

See test/tarantool-tests/lj-695-ffi-vararg-call.test.lua[1].

Fixed, repushed.

Ditto.
