  Hi,
    This patch fixes several problems:
    1. The exponent of double-precision can be put into a SImode register.
    So "xsxexpdp" doesn't require 64-bit environment. Also "xsxsigdp",
    "xsiexpdp" and "xsiexpdpf" can put exponent into a GPR register.

    2. "TARGET_64BIT" check in insn conditions should be replaced with
    "TARGET_POWERPC64" check.

    3. "lp64" check in test cases should be replaced with "has_arch_ppc64"
    check. "ilp32" check should be replaced with "dg-skip-if has_arch_ppc64".

    This patch keeps outer interfaces of these builtins unchanged.

    Bootstrapped and tested on powerpc64-linux BE and LE with no regressions.
Is this okay for trunk? Any recommendations? Thanks a lot.

gcc/
	* config/rs6000/rs6000-builtins.def
	(__builtin_vsx_scalar_extract_exp): Set return type to const unsigned
	int and set its bif-pattern to xsxexpdp_si, move it from power9-64 to
	power9 catalog.
	(__builtin_vsx_scalar_extract_sig): Set return type to const unsigned
	long long.
	(__builtin_vsx_scalar_insert_exp): Set its bif-pattern to xsiexpdp_di
	unsigned int.

	xsiexpdpf_di.
	* config/rs6000/vsx.md (xsxexpdp): Rename to ...
	(xsxexpdp_<mode>): ..., set mode of operand 0 to GPR and remove
	TARGET_64BIT check.
	(xsxsigdp): Change insn condition from TARGET_64BIT to TARGET_POWERPC64.
	(xsiexpdp): Rename to ...
	(xsiexpdp_<mode>): ..., set mode of operand 2 to GPR and change insn
	condition from TARGET_64BIT to TARGET_POWERPC64.
	(xsiexpdpf): Rename to ...
	(xsiexpdpf_<mode>): ..., set mode of operand 2 to GPR and change insn
	condition from TARGET_64BIT to TARGET_POWERPC64.
	* doc/extend.texi (scalar_extract_exp): Remove 64-bit environment
	requirement when it has a 64-bit argument.

These things are independent.  Please do independent patches (a series
is fine and even preferred, of course).  Not only is this much harder to
review the way it is, it was harder to write as well, write changelog
for, etc.  Often when you prepare patches it becomes apparent that you
should have structured things a bit differently.  That is a good time to
do exactly so :-)

Of course.  This patch doesn't edit any builtins, it changes only the
machine description.  "Of the corresponding builtins" :-)
