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. Change-Id: Ie131494be664f6c4a1bbf8c61bbbed58eac56122	2014-06-05 17:24:30 -07:00
Christopher Ferris	15b91e92a0	Fix x86 cfi directives for syscalls. The syscall generation always used 4 bytes for each push cfi directive. However, the first push should always use an offset of 8 bytes, each subsequent push after that is only 4 bytes though. Change-Id: Ibaabd107f399ef67010b9a08213783957c2f74a9	2014-05-29 19:04:36 -07:00

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.
