Rafael Espindola 2d21b25393 Allow alias to point to an arbitrary ConstantExpr. ... This patch changes GlobalAlias to point to an arbitrary ConstantExpr and it is up to MC (or the system assembler) to decide if that expression is valid or not. This reduces our ability to diagnose invalid uses and how early we can spot them, but it also lets us do things like @test5 = alias inttoptr(i32 sub (i32 ptrtoint (i32* @test2 to i32), i32 ptrtoint (i32* @bar to i32)) to i32*) An important implication of this patch is that the notion of aliased global doesn't exist any more. The alias has to encode the information needed to access it in its metadata (linkage, visibility, type, etc). Another consequence to notice is that getSection has to return a "const char *". It could return a NullTerminatedStringRef if there was such a thing, but when that was proposed the decision was to just uses "const char*" for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210062 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-03 02:41:57 +00:00
