sem_attr.adb: (Analyze_Attribute, case 'Range): when expanding X'range (N) into X'First (N) ..
2011-09-02 Ed Schonberg <schonberg@adacore.com>
* sem_attr.adb: (Analyze_Attribute, case 'Range): when expanding
X'range (N) into X'First (N) .. X'Last (N), do not share the
dimension indicator N, if present. Even though it is a static
constant, its source location may be modified when printing
expanded code under -gnatDL, and node sharing will lead to chaos
in Sprint on large files, by generating a sloc value that does
not correspond to any source file.
