2011-10-08ARM: fix segfaultBlue Swirl1-0/+1
Fix a bug in bccd9ec5f098668576342c83d90d6d6833d61d33, target-arm/op_helper.c missed a change unlike all other targets. This lead to a NULL pointer dereferences. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-01softmmu_header: pass CPUState to tlb_fillBlue Swirl1-4/+2
Pass CPUState pointer to tlb_fill() instead of architecture local cpu_single_env hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-08-07Remove unused is_softmmu parameter from cpu_handle_mmu_faultBlue Swirl1-1/+1
Parameter is_softmmu (and its evil mutant twin brother is_softmuu) is not used in cpu_*_handle_mmu_fault() functions, remove them and adjust callers. Acked-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30exec.h cleanupBlue Swirl1-2/+7
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26cpu_loop_exit: avoid using AREG0Blue Swirl1-3/+3

2009-10-17target-arm: convert NEON VZIP/VUZP/VTRN helper functions to pure TCGFilip Navara1-58/+0
The neon_trn_u8, neon_trn_u16, neon_unzip_u8, neon_zip_u8 and neon_zip_u16 helpers used fixed registers to return values. This patch replaces that with TCG code, so T0/T1 is no longer directly used by the helper functions. Bugs in the gen_neon_unzip register load code were also fixed.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-1/+1
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2007-10-14Replace is_user variable with mmu_idx in softmmu core,j_mayer1-2/+2
allowing support of more than 2 mmu access modes. Add backward compatibility is_user variable in targets code when needed. Implement per target cpu_mmu_index function, avoiding duplicated code and #ifdef TARGET_xxx in softmmu core functions. Implement per target mmu modes definitions. As an example, add PowerPC hypervisor mode definition and Alpha executive and kernel modes definitions. Optimize PowerPC case, precomputing mmu_idx when MSR register changes and using the same definition in code translation code. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3384 c046a42c-6fe2-441c-8c8c-71466251a162
