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. This reapplies r289902 with additional testcase upgrades and a change to the Bitcode record for DIGlobalVariable, that makes upgrading the old format unambiguous also for variables without DIExpressions. <rdar://problem/29250149> https://llvm.org/bugs/show_bug.cgi?id=31013 Differential Revision: https://reviews.llvm.org/D26769 llvm-svn: 290153 |

This directory contains testcases that the verifier is supposed to detect as malformed LLVM code. Testcases for situations that the verifier incorrectly identifies as malformed should go in the test/Assembler directory.
