Adrian Prantl 0eee52640f [IR] Remove the DIExpression field from DIGlobalVariable. ... This patch implements PR31013 by introducing a DIGlobalVariableExpression that holds a pair of DIGlobalVariable and DIExpression. Currently, DIGlobalVariables holds a DIExpression. This is not the best way to model this: (1) The DIGlobalVariable should describe the source level variable, not how to get to its location. (2) It makes it unsafe/hard to update the expressions when we call replaceExpression on the DIGLobalVariable. (3) It makes it impossible to represent a global variable that is in more than one location (e.g., a variable with multiple DW_OP_LLVM_fragment-s). We also moved away from attaching the DIExpression to DILocalVariable for the same reasons. <rdar://problem/29250149> https://llvm.org/bugs/show_bug.cgi?id=31013 Differential Revision: https://reviews.llvm.org/D26769 llvm-svn: 289902		2016-12-16 00:36:43 +00:00
