Version 4.45 of the MPLAB^® XC32 C/C++ Compiler introduces several enhancements to optimize application performance and streamline the development process:

• Optimized string functions: Choose between size- or speed-optimized variants for string operations that are tailored to your memory or performance requirements.
• Thumb ISA support: Link precompiled libraries for ARMv5TE architecture cores using the Thumb ISA.
• Reduced code size: Disable unnecessary thread-safe initialization of C++ local static variables to improve code efficiency.
• Enhanced coding experience: Use the xc32-clangd language server for intelligent features like code completion and go-to-definition in third-party code editors.

These features aim to benefit the compiled applications by enhancing performance, reducing memory usage and accelerating your development cycle. See the release notes for more detailed information on these new features.

Version 4.39 of the MPLAB XC32 C/C++ Functional Safety Compiler for PIC32M and SAM/PIC32C MCUs is a TÜV SÜD-certified functional safety compiler package to make your tool qualification effort easier. The package includes all the documentation and reports for a fully qualified development environment for ISO 26262 for any ASIL, IEC 61508 for any SIL, IEC 62304 and IEC 60730-1 functional safety standards. With the latest release, C++ and C applications are supported. This compiler package includes all the documentation and reports for a fully qualified development environment for EN 50128.

As a functional safety compiler, this compiler requires a functional safety license to operate. Once activated, all optimization levels and compiler features are available. For more information, see the functional safety manual that is provided in the documentation package when you purchase a functional safety license.
