now I modify the pattern into:
(define_insn "hr_vpextrv4di"
[(set (match_operand:V4DI 0 "register_operand" "=Z")
(unspec:V4DI
[(match_operand:V4DI 1 "register_operand" "Z")
(match_operand:SI 2 "const_int_operand" "")]
UNSPEC_HR_VPEXTR))]
"TARGET_HR_VECTORS"
"vpextrd\t%0,%1,%2"
[(set_attr "type" "vadd")])
then I compile the testcase:
mips64el-unknown-linux-gnu-gcc -march=hr1 -S extrd-func.c -fdump-rtl-all
I get the expand-pass rtl only, in the rtl file, it doesn't match the
pattern at all!
How can I fix this bug?
