`"v"` is the constraint code (for target-specific AMDGPU) for 32-bit VGPR register, for more info please refer - [Supported Constraint Code List for AMDGPU](https://llvm.org/docs/LangRef.html#supported-constraint-code-list)
Output Constraints are specified by an `"="` prefix as shown above ("=v"). This indicate that assemby will write to this operand, and the operand will then be made available as a return value of the asm expression. Input constraints do not have a prefix - just the constraint code. The constraint string of `"0"` says to use the assigned register for output as an input as well (it being the 0'th constraint).
Please note, there are usage limitations in ROCm compiler for inline asm support, please refer to [Inline ASM statements](https://rocm.docs.amd.com/projects/llvm-project/en/latest/reference/rocmcc.html#inline-asm-statements) for details.
## How to build and run:
- Build the sample using cmake
```
