Add a 'count' field to the DWARF subrange. The count field is necessary because there isn't a difference between the 'lo' and 'hi' attributes for a one-element array and a zero-element array. When the count is '0', we know that this is a zero-element array. When it's >=1, then it's a normal constant sized array. When it's -1, then the array is unbounded. llvm-svn: 169218

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.

Ensure that we create the context before we create a type so that we can add the newly created type to the parent. Remove last use of addToContextOwner now that it's not needed. We use createAndAddDIE to wrap around "new DIE(". Now all shareable DIEs should be added to their parents right after the creation. Reviewed off-list by Eric, Thanks. llvm-svn: 193657

Debug Info: instead of calling addToContextOwner which constructs the context after the DIE creation, we construct the context first. This touches creation of namespaces and global variables. The purpose is to handle all DIE creations similarly: constructs the context first, then creates the DIE and immediately adds the DIE to its parent.

Use the 'count' attribute to calculate the upper bound of an array. The count attribute is more accurate with regards to the size of an array. It also obviates the upper bound attribute in the subrange. We can also better handle an unbound array by setting the count to -1 instead of the lower bound to 1 and upper bound to 0. llvm-svn: 169312

DebugInfo: Use a 64 bit type for the subrange While we were encoding 64 bit values (data8) in the subrange itself, using a 32 bit type for the subrange was still confusing the gdb. Oh, and make it unsigned too. As the comment points out, this could be pushed into the frontend so that it would be 32 or 64 bit as appropriate, etc. llvm-svn: 205512

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144
