Subject: RISC-V: Add ZVFHMIN block autovec testcase
X-Git-Tag: basepoints/gcc-15~8428
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=84cbf560ff62a57432374d8a878251234ffcb99a;p=thirdparty%2Fgcc.git

RISC-V: Add ZVFHMIN block autovec testcase

To be safe, add ZVFHMIN autovec block testcase to make sure
we won't enable autovec in ZVFHMIN by mistakes.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/zvfhmin-1.c: New test.
