2011-05-03lm32: fix exception handlingMichael Walle2-31/+1
Global interrupt enable bit is already saved within the exception handler helper routine. Thus remove extra code in translation routines. Additionally, debug exceptions has always DEBA as base address. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>
2011-04-20Remove unused function parameter from cpu_restore_stateStefan Weil1-1/+1
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 Weil1-2/+1
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).

2011-04-10Fix conversions from pointer to tcg_target_longStefan Weil1-1/+1
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.
