* Use function attribute "stackrealign" to decide whether stackAkira Hatanaka2015-09-111-1/+1
| | | | | | | | | | | | | | | | | realignment should be forced. With this commit, we can now force stack realignment when doing LTO and do so on a per-function basis. Also, add a new cl::opt option "stackrealign" to CommandFlags.h which is used to force stack realignment via llc's command line. Out-of-tree projects currently using -force-align-stack to force stack realignment should make changes to attach the attribute to the functions in the IR.
