MPLAB® XC Functional Safety Compilers

Version 3.19 of the MPLAB XC8 functional safety compiler for PIC and AVR MCUs is a functional safety version of MPLAB XC8 Compiler v3.10.

This release of the compiler includes:

• Enhanced reentrant stack analysis and optimization for PIC18 and enhanced mid-range devices
• Improved shift optimizations on PIC devices
• Improved code generation for 32-bit and 64-bit integer operations on AVR devices
• Accurate disassembly provided for Integrated Development Environments (IDEs)

MPLAB XC-DSC compiler version 3.39 is an updated functional safety compiler. This release supports 3-digit versioning, bug fixes and new features. 

Upgrade your MPLAB XC32 Functional Safety Compiler to version 5.19 to unlock significant improvements for both MIPS and ARM^® core-based development. These improvements include:

• Improved code quality and performance: Built on GCC 13.2.1 with smarter optimizations, more than 25 new warning categories that identify issues at compile time and new target-specific optimizations for Cortex-M0+ and Cortex M4 cores
• Enhanced security for safety-critical applications: Register clearing, automatic variable initialization and improved stack guards to help defend against Return-Oriented Programming (ROP) attacks, along with mitigation for Common Vulnerabilities and Exposures (CVE)-2024-0151 in Arm^® TrustZone^® applications
• Support for modern development standards and flexibility: C17 and C++17 language standard support, a choice of MUSL or Picolibc Standard C libraries and Thread Local Storage support on Arm devices
• Improved tool ecosystem integration: Enhanced GNU toolchain compatibility for easier library integration and improved integration with Microsoft Visual Studio Code
