Reid Kleckner	0738a9c02e	Re-land "[WinEH] Add an EH registration and state insertion pass for 32-bit x86" ... This reverts commit r236360. This change exposed a bug in WinEHPrepare by opting win32 code into EH preparation. We already knew that WinEHPrepare has bugs, and is the status quo for x64, so I don't think that's a reason to hold off on this change. I disabled exceptions in the sanitizer tests in r236505 and an earlier revision. llvm-svn: 236508	2015-05-05 17:44:16 +00:00

Reid Kleckner	4856fc61b4	[WinEH] Add an EH registration and state insertion pass for 32-bit x86 ... This pass is responsible for constructing the EH registration object that gets linked into fs:00, which is all it does in this change. In the future, it will also insert stores to update the EH state number. I considered keeping this functionality in WinEHPrepare, but it's pretty separable and X86 specific. It has conceptually very little to do with the task of WinEHPrepare, which is currently outlining. WinEHPrepare is also in theory useful on ARM, but this logic is pretty x86 specific.
