From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001
From: upstream source tree <ports@midipix.org>
Date: Sun, 15 Mar 2015 20:14:05 -0400
Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified
 gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream
 tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+ * Interface for thread local allocation.  Memory obtained
+ * this way can be used by all threads, as though it were obtained
+ * from an allocator like GC_malloc.  The difference is that GC_local_malloc
+ * counts the number of allocations of a given size from the current thread,
+ * and uses GC_malloc_many to perform the allocations once a threashold
+ * is exceeded.  Thus far less synchronization may be needed.
+ * Allocation of known large objects should not use this interface.
+ * This interface is designed primarily for fast allocation of small
+ * objects on multiprocessors, e.g. for a JVM running on an MP server.
+ *
+ * If this file is included with GC_GCJ_SUPPORT defined, GCJ-style
+ * bitmap allocation primitives will also be included.
+ *
+ * If this file is included with GC_REDIRECT_TO_LOCAL defined, then
+ * GC_MALLOC, GC_MALLOC_ATOMIC, and possibly GC_GCJ_MALLOC will
+ * be redefined to use the thread local allocatoor.
+ *
+ * The interface is available only if the collector is built with
+ * -DTHREAD_LOCAL_ALLOC, which is currently supported only on Linux.
+ *
+ * The debugging allocators use standard, not thread-local allocation.
+ *
+ * These routines normally require an explicit call to GC_init(), though
+ * that may be done from a constructor function.
