PROFILE
Andreas Schwab
Worked on the rust-lang/gcc repository to enhance ABI stability and cross-architecture compatibility for upcoming GCC releases. Focused on finalizing the GCC 15 ABI, aligning the test suite with updated GLIBCXX and CXXABI versions, and updating libstdc++ symbol baselines for targets such as m68k-linux, riscv64-linux, and powerpc-linux. Addressed code generation correctness in the M68k backend by fixing high-part destination handling for adddi3 and subdi3 instructions with POST_INC or PRE_DEC, and introduced regression tests to ensure long-term reliability. Leveraged expertise in C, C++, compiler development, and system programming to deliver robust, maintainable improvements.

Sep 1, 2025September 2025 monthly summary focusing on key accomplishments in the rust-lang/gcc repository. Delivered a critical code-generation correctness fix for the M68k backend, specifically addressing the high part handling of the destination operand for adddi3/subdi3 when used with POST_INC or PRE_DEC. Included a regression test to protect against future regressions and to lock in the fix.

Apr 1, 2025April 2025 monthly summary for rust-lang/gcc focusing on ABI readiness and cross-architecture stability. Key outcomes include GCC 15 ABI finalization with test-suite alignment and baseline symbol updates across m68k-linux, riscv64-linux, and powerpc-linux/powerpc64-linux. These efforts improve ABI stability for future GCC releases and reduce cross-arch compatibility risks, enabling downstream projects to rely on consistent libstdc++ behavior.
