Please, review backport to 8u20. The patch applies cleanly except for c2_globals.hpp. jdk8u doesn’t have doesn’t have:
product_pd(bool, TrapBasedRangeChecks, \
"Generate code for range checks that uses a cmp and trap " \
"instruction raising SIGTRAP. Used on PPC64.") \
8028767: PPC64: (part 121): smaller shared changes needed to build C2
that I don’t think we want to backport.
It’s been in jdk9 for 2 weeks. 8032633 that enabled type speculation and stresses this change was pushed a week ago.
