2009-08-24Unbreak large mem support by removing kqemuAnthony Liguori1-35/+0
kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-01-14Add noreturn function attributeblueswir11-1/+4
Introduce noreturn attribute and attach it to cpu_loop_exit as well as interrupt/exception helpers for i386. This avoids a bunch of gcc4 warnings. [ Note that this patch comes with a workaround to include qemu-common.h even in cases where is currently causes conflicts with dyngen-exec.h. I've been told that these conflicts will get resolved in the future (/me will try to have a look as well - as time permits). ] Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6303 c046a42c-6fe2-441c-8c8c-71466251a162

this patch removes some now unused things after dyngen removal. 1. dyngen-exec.h: op_param, op _jmp and some associated macros are now unused; 2. Makefile.target: tcg-dyngen is not needed anymore 2. tcg/tcg-op.h, tcg/tcg-opc.h: gen-op.h is dead 3. tcg.c: - INDEX_op_end is now the first op - CONFIG_DYNGEN_OP is never defined 4. tcg.h: dyngen_op not needed anymore 5. exec-all.h: remove some ASM macros.
