From e8cc14e59ed3f66b84eedcc6ece65d40540edf47 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 1 Apr 2013 04:47:08 -0400 Subject: libc: rename TRUNCATE64_HAS_4_ARGS to SYSCALL_ALIGN_64BIT The reason truncate64 takes 4 args on some arches is that their ABI requires 64bit values to be aligned on register pair boundaries. Since this alignment affects more than just truncate64, rename the define to properly document its purpose. This also allows us to expand it to the other impacted syscalls (which will be done in a follow up commit).
