From e746a88b22c99f4ffe808fe2e9fb8816121cd608 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 3 May 2007 21:33:39 +0000 Subject: 2007-05-03 Joel Sherrill * ChangeLog, libcsupport/src/malloc.c, libcsupport/src/mallocfreespace.c, sapi/include/confdefs.h, score/Makefile.am, score/preinstall.am: malloc never blocks so the Region Manager is quite heavy for implementing this. This patch implements the C Program Heap directly in terms of the new Protected Heap handler. This handler is a direct use of a SuperCore Heap in conjunction with the Allocator Mutex used internally by RTEMS. This saves 3184 bytes on most SPARC test executables. * score/include/rtems/score/protectedheap.h, score/src/pheapallocate.c, score/src/pheapallocatealigned.c, score/src/pheapextend.c, score/src/pheapfree.c, score/src/pheapgetblocksize.c, score/src/pheapgetfreeinfo.c, score/src/pheapgetinfo.c, score/src/pheapinit.c, score/src/pheapresizeblock.c, score/src/pheapwalk.c: New files. --- cpukit/score/src/pheapinit.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 cpukit/score/src/pheapinit.c (limited to 'cpukit/score/src/pheapinit.c') diff --git a/cpukit/score/src/pheapinit.c b/cpukit/score/src/pheapinit.c new file mode 100644 index 0000000000..1d99fcd5f2 --- /dev/null +++ b/cpukit/score/src/pheapinit.c @@ -0,0 +1,19 @@ +/** + * COPYRIGHT (c) 1989-2007. + * On-Line Applications Research Corporation (OAR). + * + * The license and distribution terms for this file may be + * found in the file LICENSE in this distribution or at + * http://www.rtems.com/license/LICENSE. + * + * $Id$ + */ + +#if HAVE_CONFIG_H +#include "config.h" +#endif + +#include +#include + + -- cgit v1.2.3
