From 1e2d2f09470a2be58a98420b4cecae731b156ee8 Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Tue, 11 Nov 2014 17:05:02 -0500 Subject: [dev.cc] runtime: convert memory allocator and garbage collector to Go The conversion was done with an automated tool and then modified only as necessary to make it compile and run. [This CL is part of the removal of C code from package runtime. See golang.org/s/dev.cc for an overview.] LGTM=r R=r CC=austin, dvyukov, golang-codereviews, iant, khr https://golang.org/cl/167540043 --- src/runtime/mfixalloc.c | 64 ------------------------------------------------- 1 file changed, 64 deletions(-) delete mode 100644 src/runtime/mfixalloc.c (limited to 'src/runtime/mfixalloc.c') diff --git a/src/runtime/mfixalloc.c b/src/runtime/mfixalloc.c deleted file mode 100644 index d670629dae..0000000000 --- a/src/runtime/mfixalloc.c +++ /dev/null @@ -1,64 +0,0 @@ -// Copyright 2009 The Go Authors.
