From 49aa652db810ebdca3a662ebd5b0468bd08ec688 Mon Sep 17 00:00:00 2001 From: Sergey Bugaev Date: Sat, 23 Mar 2024 20:32:44 +0300 Subject: Allow glibc to be compiled without EXEC_PAGESIZE We would like to avoid statically defining any specific page size on aarch64-gnu, and instead make sure that everything uses the dynamic page size, available via vm_page_size and GLRO(dl_pagesize). There are currently a few places in glibc that require EXEC_PAGESIZE to be defined. Per Roland's suggestion [0], drop the static GLRO(dl_pagesize) initializers (for now, only if EXEC_PAGESIZE is not defined), and don't require EXEC_PAGESIZE definition for libio to enable mmap usage.
