DISubrange supports unsigned lower/upper array bounds, so let's not fake it in the end while emitting DWARF. If a FE needs to encode signed lower/upper array bounds then we need to extend DISubrange or ad DISignedSubrange. llvm-svn: 144937

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.

Implement DW_TAG_subrange_type with DW_AT_count rather than DW_AT_upper_bound This allows proper disambiguation of unbounded arrays and arrays of zero bound ("struct foo { int x[]; };" and "struct foo { int x[0]; }"). GCC instead produces an upper bound of -1 in the latter situation, but count seems tidier. This way lower_bound is provided if it's not the language default and count is provided if the count is known, otherwise it's omitted. Simple. If someone wants to look at rdar://problem/12566646 and see if this change is acceptable to that bug/fix, that might be helpful (see the empty-and-one-elem-array.ll test case which cites that radar). llvm-svn: 218726

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
