See http://lists.llvm.org/pipermail/llvm-dev/2020-April/140549.html For the record, GNU ld changed to 64k max page size in 2014 https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=7572ca8989ead4c3425a1500bc241eaaeffa2c89 "[RFC] ld/ARM: Increase maximum page size to 64kB" Android driver forced 4k page size in AArch64 (D55029) and ARM (D77746). A binary linked with max-page-size=4096 does not run on a system with a higher page size configured. There are some systems out there that do this and it leads to the binary getting `Killed!` by the kernel. In the non-linker-script cases, when linked with -z noseparate-code (default), the max-page-size increase should not cause any size difference. There may be some VMA usage differences, though.
