From: Juzhe-Zhong <juzhe.zh...@rivai.ai>
This patch support FMA auto-vectorization pattern.
1. Let's RA decide vmacc or vmadd.
2. Fix bug of vector.md which generate incorrect information to VSETVL
PASS when testing ternop-3.c.
gcc/ChangeLog:
* config/riscv/autovec.md (fma<mode>4): New pattern.
(*fma<mode>): Ditto.
* config/riscv/riscv-protos.h (enum insn_type): Add ternary enum.
(emit_vlmax_ternop_insn): New function.
* config/riscv/riscv-v.cc (emit_vlmax_ternop_insn): Ditto.
* config/riscv/vector.md: Fix ternary patterns bug.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/rvv.exp: Add ternop tests.
* gcc.target/riscv/rvv/autovec/ternop/ternop-1.c: New test.
* gcc.target/riscv/rvv/autovec/ternop/ternop-2.c: New test.
* gcc.target/riscv/rvv/autovec/ternop/ternop-3.c: New test.
* gcc.target/riscv/rvv/autovec/ternop/ternop_run-1.c: New test.
* gcc.target/riscv/rvv/autovec/ternop/ternop_run-2.c: New test.
* gcc.target/riscv/rvv/autovec/ternop/ternop_run-3.c: New test.

+;; We can't expand FMA for the following reasons:
+;; 1. Before RA, we don't know which multiply-add instruction is the ideal one.
+;; The vmacc is the ideal instruction when operands[3] overlaps operands[0].
+;; The vmadd is the ideal instruction when operands[1|2] overlaps
operands[0].
+;; 2. According to vector.md, the multiply-add patterns has 'merge' operand
which
+;; is the operands[5]. Since operands[5] should overlap operands[0], this
operand
+;; should be allocated the same regno as operands[1|2|3].
+;; 3. The 'merge' operand is always a real merge operand and we don't allow
undefined
+;; operand.
+;; 3. The operation of FMA pattern needs VLMAX vsetlvi which needs a VL
operand.
+;;
+;; In this situation, we design the codegen of FMA as follows:
+;; 1. clobber a scratch in the expand pattern of FMA.
+;; 2. Let's RA decide which input operand (operands[1|2|3]) overlap
operands[0].
+;; 3. Generate instructions (vmacc or vmadd) according to the register
allocation
