2011-10-01softmmu_header: pass CPUState to tlb_fillBlue Swirl
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 Swirl
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 Swirl
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>
2011-07-20Fix unassigned memory access handlingBlue Swirl
cea5f9a28faa528b6b1b117c9ab2d8828f473fef exposed bugs in unassigned memory access handling. Fix them by always passing CPUState to the handlers. Reported-by: Hervé Poussineau <hpoussin@reactos.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26cpu_loop_exit: avoid using AREG0Blue Swirl
Make cpu_loop_exit() take a parameter for CPUState instead of relying on global env. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-04-20Remove unused function parameter from cpu_restore_stateStefan Weil
The previous patch removed the need for parameter puc. Is is now unused, so remove it. Cc: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Stefan Weil <weil@mail.berlios.de>
2011-04-17softfloat: rename float*_eq() into float*_eq_quiet()Aurelien Jarno
float*_eq functions have a different semantics than other comparison functions. Fix that by first renaming float*_quiet() into float*_eq_quiet(). Note that it is purely mechanical, and the behaviour should be unchanged. That said it clearly highlight problems due to this different semantics, they are fixed later in this patch series.

2011-01-23microblaze: cleanup helper_addkcEdgar E. Iglesias
Remove unused addition and rename to helper_carry. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2011-01-22microblaze: Improve subkcEdgar E. Iglesias
Move code from the helper into the translator. The remaining helper parts can reuse helper_addkc, making it possible to remove helper_subkc entirely. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2011-01-22microblaze: Improve addkcEdgar E. Iglesias
* Optimize handling when carry is not updated. * Optimize handling for adds with nop semantics. * Move code from helper_addkc to the translator making helper_addkc PURE and CONST. Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2011-01-02softfloat: Rename float*_is_nan() functions to float*_is_quiet_nan()Peter Maydell
The softfloat functions float*_is_nan() were badly misnamed, because they return true only for quiet NaNs, not for all NaNs. Rename them to float*_is_quiet_nan() to more accurately reflect what they do. This change was produced by: perl -p -i -e 's/_is_nan/_is_quiet_nan/g' $(git grep -l is_nan) (with the results manually checked.)

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori
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.
