Description

An integer that is set to 1 when the compiler supports architecture extension test macros. The value of an architecture extension test macro is computed based on its version number, using this formula:

major_v * 1000000 + minor_v * 1000 + revision_v

Example

If the F extension is version 2.2, __riscv_f is defined to 2002000.

If the B extension is version 0.92, __riscv_b is defined to 92000.
