PROFILE
Matthew Fortune
Worked on the rust-lang/gcc repository to enhance MIPS backend support by developing targeted compiler features and improving test infrastructure. Delivered a new -mgrow-frame-downwards option for MIPS16 in C and C++, optimizing stack frame growth and enabling efficient 16-bit spill-slot access. Refined the testsuite by replacing ISA-specific checks with a generic HAS_LDC flag, increasing portability and reliability across MIPS variants. Removed unsupported MSA and microMIPS R5 features, adding compile-time error checks to prevent misconfiguration. Focused on configuration hygiene, cross-assembler compatibility, and reproducible builds, applying skills in compiler development, embedded systems, and test automation to streamline maintenance and onboarding.

Aug 1, 2025Month 2025-08: Focused on delivering a performance-oriented MIPS16 optimization in the GCC backend for rust-lang/gcc, plus strengthening the MIPS testsuite reliability. Key outcomes include a new compiler option -mgrow-frame-downwards to optimize stack frame growth and enable 16-bit spill-slot access, and a set of testsuite fixes that replace ISA-specific checks with a generic HAS_LDC flag, improving portability and robustness across MIPS micromips/mips16 and LDC scenarios. These changes reduce code size, improve efficiency, and increase confidence in the MIPS codegen through a more robust testsuite.
