SAN19-412 - Investigating generated code for HPC applications on AArch64 by GCC and LLVM

Session Abstract

Recently, compiler optimizations and their improvements for AArch64 have been actively added to GCC and LLVM. For optimizations for HPC applications, GCC with a Fortran front end is superior to LLVM. In this presentation, we compare the code generated by GCC and LLVM for kernel parts of HPC applications on AArch64, and investigate the current problems of LLVM and propose solutions for them.
