I tried to build jdk9/hs-rt on Fedora 22 with GCC 5.1.1 . However, libjvm.so did not have .note.stapsdt section. When I ran make command with LOG=info, I found a message as below: --------------- **NOTICE** Dtrace support disabled: gcc version is too old --------------- hotspot/make/linux/makefiles/dtrace.make checks C compiler version. However, its condition cannot check 5.x or later. So I fix the condition, and it works fine on my environment. This issue is occurred on 8u-dev. So I also want to fix it for 8u-dev.
