AArch64: Autogenerated syscalls for AArch64 This patch adds AArch64 syscalls, autogenerated using: ./libc/tools/gensyscalls.py Change-Id: I1cc60430423ecb52a35448bf2c358b82136b2f16 Signed-off-by: Serban Constantinescu <serban.constantinescu@arm.com> 2013-10-11 00:05:06 +02:00			`/* Generated by gensyscalls.py.

Stop using the non-uapi <linux/err.h> header file. We only need it for MAX_ERRNO, and it's time we had somewhere to put the little assembler utility macros we've been putting off writing.

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.

Remove the useless _C_LABEL from generated system calls. Change-Id: Id1d2fd39972652831ea825f6f9cf940b08f42b5c 2014-02-20 03:59:19 +01:00			`.hidden __exit`
