| hyrcanus | "Also, I have noticed that on Ubuntu 20.10 with GCC 10.2.0, compiling natively with -mno-outline-atomics does NOT remove the init_have_lse_atomics function which still gets executed by early ELF initialization logic. On Fedora with GCC 10.2.1, the init_have_lse_atomics is removed. I wonder why this happens." | 09:22 |
