Filipe Cabecinhas	fe5e5afd53	[ubsan] Minimize size of data for type_mismatch (Redo of D19667) ... Summary: This patch makes the type_mismatch static data 7 bytes smaller (and it ends up being 16 bytes smaller due to alignment restrictions, at least on some x86-64 environments). It revs up the type_mismatch handler version since we're breaking binary compatibility. I will soon post a patch for the compiler-rt side.

Ivan Krasin	9103036f5f	Explicitly specify that ubsan-vtable-checks is x86-64. ... This should fix a failure on PowerPC introduced by r287181. llvm-svn: 287185	2016-11-17 01:09:04 +00:00
Ivan Krasin	d98f5d78cb	Insert a type check before reading vtable. ... Summary: this is to prevent a situation when a pointer is invalid or null, but we get to reading from vtable before we can check that (possibly causing a segfault without a good diagnostics).
