PROFILE

Hongyu Wang

Worked on the rust-lang/gcc repository, focusing on low-level compiler development and code generation in C and C++. Delivered a targeted fix in the GCC backend to ensure correct emission of the nf variant for rotate instructions under TARGET_APX_NF, addressing a code generation issue and adding a regression test to validate the behavior. Later, enhanced Scalar Replacement of Aggregates (SRA) on x86 by increasing the scalarization size limit using MOVE_MAX, enabling support for larger aggregates and vectors. This work involved assembly language expertise and low-level optimization, with automated tests added to confirm the robustness of the new SRA implementation.
