Subject: gdb: remove COMPUNIT_DIRNAME macro, add getter/setter
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0d9acb4531cfe336b2b335fbaa1f2ef878a6e4d9;p=binutils-gdb.git

gdb: remove COMPUNIT_DIRNAME macro, add getter/setter

Add a getter and a setter for a compunit_symtab's dirname.  Remove the
corresponding macro and adjust all callers.
