Subject: RISC-V: Add test cases for vzext.vf8 reg overlap
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=73ffdaa29d588d2ae01a044d88c3b4ee642bab44;p=thirdparty%2Fgcc.git

RISC-V: Add test cases for vzext.vf8 reg overlap

Add test cases for vzext.vf8 register group overlap, please
note it is not overlap as much as possible.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/group_overlap/vzext_vf8-u8-m1.c: New test.
	* gcc.target/riscv/rvv/autovec/group_overlap/vzext_vf8-u8-mf2.c: New test.
	* gcc.target/riscv/rvv/autovec/group_overlap/vzext_vf8-u8-mf4.c: New test.
	* gcc.target/riscv/rvv/autovec/group_overlap/vzext_vf8-u8-mf8.c: New test.
