Target Selection - Target Selection

The following is a list of Target Selection options.

```
-march=<cpu>
```
Enables Clang/Flang to generate code for a specific processor of a family. For example, if you specify -march=znver1, the compiler can generate instructions that are valid on AMD 17h and later processors.
```
-march=znver1
```
Use this architecture option to enable the best code generation and tuning for AMD “Zen”-based x86 architecture. All the x86 AMD “Zen” ISA and associated intrinsics are supported.
```
-march=znver2
```
Use this architecture option to enable the best code generation and tuning for AMD “Zen2”-based x86 architecture. All x86 AMD “Zen2” ISA and associated intrinsics are supported.
```
-march=znver3
```
Use this architecture option to enable the best code generation and tuning for AMD “Zen3”-based x86 architecture. All x86 AMD “Zen3” ISA and associated intrinsics are supported.
```
-march=znver4
```
Use this architecture option to enable the best code generation and tuning for AMD “Zen4”-based x86 architecture. All x86 AMD “Zen4” ISA and associated intrinsics are supported.
```
-march=znver5
```
Use this architecture option to enable the best code generation and tuning for AMD “Zen5”-based x86 architecture. All x86 AMD “Zen5” ISA and associated intrinsics are supported.
```
-march=native
```
Use this architecture option to generate code at compilation time by determining the processor type of the compiling machine. Using -march=native enables all instruction subsets supported by the local machine.
