From 7efad83d430f4d824f2aaa75edea5106f6ff8aae Mon Sep 17 00:00:00 2001 From: Elliott Hughes Date: Mon, 8 Sep 2014 15:25:01 -0700 Subject: Ensure __set_errno is still visible on LP32. The use of the .hidden directive to avoid going via the PLT for __set_errno had the side-effect of actually making __set_errno hidden (which is odd because assembler directives don't usually affect symbols defined in a different file --- you can't even create a weak reference to a symbol that's defined in a different file). This change switches the system call stubs over to a new always-hidden __set_errno_internal and has a visible __set_errno on LP32 just for binary compatibility with old NDK apps.
