Subject: RISC-V: Add testcase for unsigned scalar SAT_MUL form 16
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a5d79a657e0fb4fb1558fa710ce83c267c40ffda;p=thirdparty%2Fgcc.git

RISC-V: Add testcase for unsigned scalar SAT_MUL form 16

The form 16 of unsigned scalar SAT_MUL has supported from
the previous change.  Thus, add the test cases to make sure
it works well.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/sat/sat_arith.h: Add test helper macros.
	* gcc.target/riscv/sat/sat_u_mul-17-u16-from-u128.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-17-u16-from-u32.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-17-u16-from-u64.rv32.c: New test.
	* gcc.target/riscv/sat/sat_u_mul-17-u16-from-u64.rv64.c: New test.
