Bill Wendling	32e4544198	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	2012-12-04 21:34:03 +00:00
Bill Wendling	8ade948576	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	2012-12-04 06:20:49 +00:00
