[PATCH v4 09/16] RISC-V: define the elements of the VCSR vector CSR

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Heiko Stuebner <heiko@xxxxxxxxx>

The VCSR CSR contains two elements VXRM[2:1] and VXSAT[0].

Define constants for those to access the elements in a readable way.
