From 9f6f34892fdfff87c49a9df4c1e34790c0fa1272 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Fri, 15 May 2015 15:07:20 -0700 Subject: Abort on OOM by default in FX_Alloc(). Add a FX_TryAlloc() for those few cases where we might need to continue in face of OOM. Remove FX_AllocNL() (the context of its use would suggest that NL means "No Limit"). This is used for some big allocations, so replace it with TryAlloc(). Large allocations may be worth trying to continue from, since there are few and they have a large chance of failing.
