platform_bionic/libc/arch-x86_64/syscalls/truncate.S
Elliott Hughes 15a0456d0b Remove unnecessary instructions from x86/x86_64 syscalls.
__set_errno returns -1 exactly so that callers don't need to bother.
The other architectures were already taking advantage of this, but
no one had ever fixed x86 and x86_64.
