From 9d16a79b18f43faebbe8155dbc14896e9b7d8a2e Mon Sep 17 00:00:00 2001 From: Jim Huang Date: Mon, 27 Sep 2010 19:23:06 +0800 Subject: [PATCH] Hide the symbol of helper function __libc_android_abort Ideally __libc_android_abort would be static, but it could not be because gcc would not allow calling a static function from an asm statement. Instead, using GCC visibility is work around.
