wants to merge 1 commit into from

@coleenp coleenp commented Oct 12, 2020

Moved the duplicated code from posix based platform/cpu combinations into os_posix.cpp. Left a little function to determine frame at stack banging point for compiled methods (you can suggest a better name for it) to capture the difference.

There are a bit of ifdefs but now there are less copies.

Tested with tier1-3 and stack overflow tests in vmTestbase/nsk/stress/stack on linux-x86-debug,macosx-x86-debug,windows-x86-debug. Built aarch64, arm32, ppc, s390, and zero. Testing on these platforms would be welcome.
