Subject: (__builtin_new): If __new_handler returns, keep trying to allocate the memory.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=442e881d89e931d7aa1f6794e6814d6eab08a26f;p=gcc.git

(__builtin_new): If __new_handler returns, keep trying to allocate the memory.

(__default_new_handler): Add __ to beginning of name to avoid namespace
clashing.
