Subject: RISC-V: Fix indexed store output template [PR123780].
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7edd9284a6a981cfff95b3d1822f4c029ec78271;p=thirdparty%2Fgcc.git

RISC-V: Fix indexed store output template [PR123780].

This one slipped through when bulk-changing the gather/scatter patterns.

Regtested on rv64gcv_zvl512b.  Going to commit as obvious.

	PR target/123780

gcc/ChangeLog:

	* config/riscv/vector.md: Correct output template.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/base/pr123780.c: New test.
