testsuite: arm: Update expected asm in armv8_2-fp16-neon-2.c
With the changes in r15-1579-g792f97b44ff, the test_vmul_n_16x8 function
does not contain any vdup.16 q* r* instruction with -mfloat-abi=softfp.
The differnce between r15-1578-g5185274c76c and r15-1579-g792f97b44ff
with -mfloat-abi=softfp for the function is:
.global test_vmul_n_16x8
.syntax unified
.arm
.type test_vmul_n_16x8, %function
test_vmul_n_16x8:
@ args = 4, pretend = 0, frame = 0
@ frame_needed = 0, uses_anonymous_args = 0
@ link register save eliminated.
vmov d16, r0, r1 @ v8hf
vmov d17, r2, r3
- ldrh r3, [sp] @ __fp16
- vdup.16 q9, r3
+ vld1.16 {d18[], d19[]}, [sp]
vmul.f16 q8, q9, q8
vmov r0, r1, d16 @ v8hf
vmov r2, r3, d17
bx lr
.size test_vmul_n_16x8, .-test_vmul_n_16x8
gcc/testsuite/ChangeLog:
* gcc.target/arm/armv8_2-fp16-neon-2.c: Expect 3 vdup.16 q* r*
when in arm_hf_eabi else 2.
