Hi,
Only some PPC processors have a sqrt instruction.
Currently, intrinsic for dsqrt is used if a corresponding rule is implemented in the .ad file (has_match_rule()). Instead, call match_ruole_supported(), which allows to check processor properties.
Also adapt PPC64 .ad file to this.
Please review and test this change http://cr.openjdk.java.net/~goetz/webrevs/8035394-1-fltRck/
It also needs to go to jdk8u via ppc-aix-port/stage.
Best regards, Goetz.
