This commit updates the stackmap format to version 1 to indicate the reorganizaion of several fields. This was done in order to align stackmap entries to their natural alignment and to minimize padding. Fixes <rdar://problem/16005902> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205254 91177308-0d34-0410-b5e6-96231b3b80d8
