Subject: [PATCH] RISC-V: Add autovec FP widening/narrowing.
Hi,
this patch adds FP widening and narrowing autovec expanders as well as
tests. Conceptually similar to integer extension/truncation, we emulate
_Float16 -> double by two vfwcvts and double -> _Float16 by two vfncvts.
Optimizations to create widening operations will be added separately.
Regards
Robin
gcc/ChangeLog:
* config/riscv/autovec.md (extend<v_double_trunc><mode>2): New
expander.
(extend<v_quad_trunc><mode>2): Dito.
(trunc<mode><v_double_trunc>2): Dito.
(trunc<mode><v_quad_trunc>2): Dito.
* config/riscv/vector-iterators.md: Add VQEXTF and HF to
V_QUAD_TRUNC and v_quad_trunc.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/conversions/vfncvt-run.c: New test.
