# Commit 8155476765a5bdecea1534b46562cf28e0113a9a # Date 2018-01-25 11:34:17 +0000 # Author Wei Liu <wei.liu2@citrix.com> # Committer Wei Liu <wei.liu2@citrix.com> x86: fix GET_STACK_END AIUI the purpose of having the .if directive is to make GET_STACK_END work with any general purpose registers. The code as-is would produce the wrong result for r8. Fix it.
