Hi,
This patch is for internal issue1136. It changes insn condition from
TARGET_64BIT to TARGET_POWERPC64 for VSX scalar extract/insert instructions.
These instructions all use DI registers and can be invoked with -mpowerpc64
in a 32-bit environment.
This patch also changes prototypes of related built-ins and target selector
of test cases.
Bootstrapped and tested on powerpc64-linux BE and LE with no regressions.
Is this okay for trunk? Any recommendations? Thanks a lot.
