Subject: make symtab::dirname const
X-Git-Tag: gdb-7.7-release~262
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8e96694e31aedc28a4e2a00b28099158a8bd4a5a;p=external%2Fbinutils.git

make symtab::dirname const

This makes symtab::dirname const and updates one spot to avoid an
intermediate constless result.

	* buildsym.c (end_symtab_from_static_block): Use obstack_copy0.
	* symtab.h (struct symtab) <dirname>: Now const.
