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/preinstall.am | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'cpukit/score/preinstall.am') diff --git a/cpukit/score/preinstall.am b/cpukit/score/preinstall.am index c82a22b21b..a43bc4da11 100644 --- a/cpukit/score/preinstall.am +++ b/cpukit/score/preinstall.am @@ -91,6 +91,10 @@ $(PROJECT_INCLUDE)/rtems/score/heap.h: include/rtems/score/heap.h $(PROJECT_INCL $(INSTALL_DATA) $< $(PROJECT_INCLUDE)/rtems/score/heap.h PREINSTALL_FILES += $(PROJECT_INCLUDE)/rtems/score/heap.h +$(PROJECT_INCLUDE)/rtems/score/protectedheap.h: include/rtems/score/protectedheap.h $(PROJECT_INCLUDE)/rtems/score/$(dirstamp) + $(INSTALL_DATA) $< $(PROJECT_INCLUDE)/rtems/score/protectedheap.h +PREINSTALL_FILES += $(PROJECT_INCLUDE)/rtems/score/protectedheap.h + $(PROJECT_INCLUDE)/rtems/score/interr.h: include/rtems/score/interr.h $(PROJECT_INCLUDE)/rtems/score/$(dirstamp) $(INSTALL_DATA) $< $(PROJECT_INCLUDE)/rtems/score/interr.h PREINSTALL_FILES += $(PROJECT_INCLUDE)/rtems/score/interr.h -- cgit v1.2.3
