Innovating with Toolchains in 2023
summary
Glibc adds three kernel-backed high-quality randomness functions and a new call to free a dying process’s memory, shown with a fork/timer test and the process_mrelease and process_madvise interfaces and their return semantics. GCC 13 ships startup-size wins by moving std::string init into the shared library, AddressSanitizer/LTO tweaks, and x86 codegen for new ISAs with examples using AMX tile dot-product intrinsics and VPMADD52-style vector instructions for INT8/VNNI workloads.
