Summary

Increase upper limit of the LoopOptsCount flag

Problem

Currently LoopOptsCount has to be an integer in the range 5-43. With default value being 43. Especially for testing the user should be able to use values larger than 43.

Solution

Increase upper limit of the LoopOptsCount flag from 43 to max_jint. Keep the default value as 43

Specification

In shared/opto/c2_globals.hpp change allowed flag value range to:

  product(intx, LoopOptsCount, 43,                                          \
          "Set level of loop optimization for tier 1 compiles")             \
          range(5, max_jint)
