Recently, all binutils versions have been renamed after a GPL compliance issue was found and fixed in binutils; http://sourceware.org/ml/binutils/2011-08/msg00198.html Although legacy symlinks have been put in place, we should now use the new, real version strings.

|
|
|
* ldlang.c: Formatting.
|
|
(walk_wild_consider_section): Remember return value from wildcardp.
|
|
(is_simple_wild): Use strcspn instead of 2 strpbrk calls and strlen.
|
|
(wild_spec_can_overlap): Use strcspn instead of strpbrk and strlen.
|
|
