Subject: Remove allocate_block and allocate_global_block
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=522553837be31e09d182a8974429650f68c108f3;p=binutils-gdb.git

Remove allocate_block and allocate_global_block

This removes allocate_block and allocate_global_block in favor of
simply calling 'new'.
