Eric Christopher	8cab6edf4f	Add a name for the anonymous type we're creating for subrange ... types and a FIXME for what we should be doing. Should solve the immediacy of PR12069 where our debug info is crashing another tool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171536 91177308-0d34-0410-b5e6-96231b3b80d8	2013-01-04 21:51:53 +00:00
Bill Wendling	9493dae613	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169312 91177308-0d34-0410-b5e6-96231b3b80d8	2012-12-04 21:34:03 +00:00
Bill Wendling	a7645a3c66	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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169218 91177308-0d34-0410-b5e6-96231b3b80d8	2012-12-04 06:20:49 +00:00
