Subject: aarch64: Add ACLE macro __ARM_FEATURE_SVE_PREDICATE_OPERATORS
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=63c6821bf4c5ee38b2152626c202727e1e16b4cd;p=thirdparty%2Fgcc.git

aarch64: Add ACLE macro __ARM_FEATURE_SVE_PREDICATE_OPERATORS

This patch enables ACLE macro __ARM_FEATURE_SVE_PREDICATE_OPERATORS to indicate
that C/C++ language operations are available natively on SVE ACLE type svbool_t.

gcc/

	* config/aarch64/aarch64-c.cc (aarch64_update_cpp_builtins): Define
	__ARM_FEATURE_SVE_PREDICATE_OPERATORS.

gcc/testsuite

	* gcc.target/aarch64/sve/acle/general/attributes_1.c: Update test for
	__ARM_FEATURE_SVE_PREDICATE_OPERATORS.
	* gcc.target/aarch64/sve/acle/general/attributes_9.c: New.
