From faf07963cb03f98d52ca1f7fde7482a3cb309bcc Mon Sep 17 00:00:00 2001 From: pbrook Date: Sun, 11 Nov 2007 02:51:17 +0000 Subject: [PATCH] Split block API from vl.h. Remove QEMU_TOOL. Replace with QEMU_IMG and NEED_CPU_H. Avoid linking qemu-img against whole system emulatior. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3578 c046a42c-6fe2-441c-8c8c-71466251a162 --- Makefile | 22 +++-- Makefile.target | 4 +- aes.c | 2 +- block-bochs.c | 2 +- block-cloop.c | 2 +- block-cow.c | 2 +- block-dmg.c | 2 +- block-parallels.c | 2 +- block-qcow.c | 2 +- block-qcow2.c | 2 +- block-raw.c | 35 +++---- block-vmdk.c | 2 +- block-vpc.c | 2 +- block-vvfat.c | 2 +- block.c | 12 ++- block.h | 157 +++++++++++++++++++++++++++++++ block_int.h | 4 + cutils.c | 2 +- qemu-common.h | 83 ++++++++++++++++ qemu-img.c | 2 +- vl.h | 235 +--------------------------------------------- 21 files changed, 307 insertions(+), 271 deletions(-) create mode 100644 block.h create mode 100644 qemu-common.h diff --git a/Makefile b/Makefile index d0ec057204..73f9e3db18 100644 --- a/Makefile +++ b/Makefile @@ -13,7 +13,6 @@ BASE_LDFLAGS += $(OS_LDFLAGS) $(ARCH_LDFLAGS) CPPFLAGS += -I. -I$(SRC_PATH) -MMD -MP CPPFLAGS += -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -CPPFLAGS += -DQEMU_TOOL LIBS= ifdef CONFIG_STATIC BASE_LDFLAGS += -static @@ -33,15 +32,23 @@ subdir-%: dyngen$(EXESUF) libqemu_common.a recurse-all: $(patsubst %,subdir-%, $(TARGET_DIRS)) +####################################################################### +# BLOCK_OBJS is code used by both qemu system emulation and qemu-img + +BLOCK_OBJS=cutils.o +BLOCK_OBJS+=block-cow.o block-qcow.o aes.o block-vmdk.o block-cloop.o +BLOCK_OBJS+=block-dmg.o block-bochs.o block-vpc.o block-vvfat.o +BLOCK_OBJS+=block-qcow2.o block-parallels.o + ###################################################################### -# libqemu_common.a: target indepedent part of system emulation.
