IAR Build Tools for RISC-V

• Scalar Cryptography (Zkn, Zks) Instruction Set Extensions
  The Zkn and Zks RISC-V extensions implement Scalar Cryptography instructions aimed at accelerating the NIST and ShangMi cryptographic standards, respectively. 
• Code Size Reduction (Zcb, Zcmp) Instruction Set Extensions
  The Zcb standard extension provides compressed variants of a number of existing extensions. The Zcmp extension is a set of instructions (including push/pop) that can be executed as a series of existing 32-bit RISC-V instructions.
• Improved code generation for the Bitmanip extensions
• Optimized ceil, floor, and round libraries for soft-float and Zfinx
• Support for misaligned data access
• New compiler GCC extensions 
• New devices

Zfinx and Zdinx standard RISC-V extensions

• Support for standard extensions for Floating-Point in Integer Registers.

CMO standard RISC-V extensions

• Support for the Cache Management Operations (CMO) extensions Zicbom, Zicboz, and Zicbop.

Auto compressing Assembler

• When support for the C extension is enabled, the assembler automatically converts normal instructions to compressed instructions.

Optimized ceil, floor, and rounding library functions

Library support for the C++17 language standard

The toolset now includes a new C++ library that supports C++17 library features.

Cross-platform support

In addition to previous support for Ubuntu and Red Hat, the latest version also supports Windows.
