PROFILE
Andreas Schwab
Andreas Schwab contributed to the rust-lang/gcc repository by advancing ABI stability and cross-architecture compatibility for GCC 15. He finalized ABI readiness, aligning the test suite and updating baseline symbols for targets such as m68k-linux, riscv64-linux, and powerpc-linux, ensuring consistent libstdc++ behavior across platforms. Using C and C++, he focused on system libraries, build systems, and compiler development to reduce compatibility risks for downstream projects. Additionally, he addressed a code generation bug in the M68k backend, implementing a targeted fix for adddi3/subdi3 instructions and introducing regression tests. His work demonstrated depth in system programming and cross-compilation.

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.
