Subject: Don't erase empty indices in DWARF reader
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1a6191f1a614f61d20bfe414b81c39a8ca785cc7;p=binutils-gdb.git

Don't erase empty indices in DWARF reader

The DWARF reader has some code to remove empty indices.  However, I
think this code has been obsolete since some earlier changes to
parallel_for_each.  This patch removes this code.
