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>

2011-06-26Move cpu_has_work and cpu_pc_from_tb to cpu.hBlue Swirl
Move functions cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h. This is needed by later patches. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26exec.h: fix coding style and change cpu_has_work to return boolBlue Swirl

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>
2011-04-20Remove unused function parameters from gen_pc_load and rename the functionStefan Weil
Function gen_pc_load was introduced in commit d2856f1ad4c259e5766847c49acbb4e390731bd4. The only reason for parameter searched_pc was a debug statement in target-i386/translate.c. Parameter puc was needed by target-sparc until commit d7da2a10402f1644128b66414ca8f86bdea9ae7c. Remove searched_pc from the debug statement and remove both parameters from the parameter list of gen_pc_load. As the function name gen_pc_load was also misleading, it is now called restore_state_to_opc. This new name was suggested by Peter Maydell, thanks. v2: Remove last parameter, too, and rename the function. v3: Fix [] typo in target-arm/translate.c. Fix wrong SHA1 object name in commit message (copy+paste error).

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.

2011-04-10Fix conversions from pointer to tcg_target_longStefan Weil
tcg_gen_exit_tb takes a parameter of type tcg_target_long, so the type casts of pointer to long should be replaced by type casts of pointer to tcg_target_long (suggested by Blue Swirl). These changes are needed for build environments where sizeof(long) != sizeof(void *), especially for w64.

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.)
