From 15b91e92a0bb4a15b4f2258bea332f4a67fa94d7 Mon Sep 17 00:00:00 2001 From: Christopher Ferris Date: Thu, 29 May 2014 18:17:09 -0700 Subject: 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.
