From ad27d44ebe950335616f37e36863469dc181b455 Mon Sep 17 00:00:00 2001 From: Alistair Francis Date: Wed, 18 Sep 2019 09:28:51 -0700 Subject: [PATCH] runsv: Use 64 prefix syscall if we have to Some 32-bit architectures no longer have the 32-bit time_t syscalls. Instead they have suffixed syscalls that returns a 64-bit time_t. If the architecture doesn't have the non-suffixed syscall and is using a 64-bit time_t let's use the suffixed syscall instead. This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel headers. If an architecture only supports the suffixed syscalls, but is still using a 32-bit time_t report a compilation error. This avoids us have to deal with converting between 64-bit and 32-bit values. There are currently no architectures where this is the case.
