[Lldb-commits] [PATCH] D67911: [LLDB] [Windows] Add missing ifdefs to fix building for non-x86 architectures

[Martin Storsjö via Phabricator via lldb-commits]

mstorsjo created this revision.
mstorsjo added reviewers: amccarth, labath, hhb, compnerd, asmith.
Herald added subscribers: JDevlieghere, abidh.
Herald added a project: LLDB.

While debugging on those architectures might not be supported yet, the generic 
code should still be buildable. This file accesses x86 specific fields in the 
CONTEXT struct.
