Subject: * dwarf.c (display_debug_names): Initialize hash_prev.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0a79bef4f206d89214c48454a4302d6b6f8f68c0;p=binutils-gdb.git

* dwarf.c (display_debug_names): Initialize hash_prev.

gcc-4.3.0 warns that it may be used uninitialized.  It takes a look
and a half at the code to understand that it's false.
