R52+ vldr does not load the data

Grace WANG

Hi

We are using Cortex-R52+ as followings

float32 test = 123.3f;  the value of the variable is not changed.

We found that sometimes if(test<123.0f) will tells true and make err_cnt++.

At that time, I reads the S15 and it has a legacy value. I suspect that the legacy value in S15 is due to other floating-point calculation and it seems that the vldr does not load the value from [r3] to S15.

Could you help give the possible reasons ? Or is there any limitation for the floating-point calculation ?

BR, Grace
