2014-03-13cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber1-2/+3
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-02-04target-lm32: stop VM on illegal or unknown instructionMichael Walle1-38/+68
Instead of translating the instruction to a no-op, pause the VM and display a message to the user. As a side effect, this also works for instructions where the operands are only known at runtime. Signed-off-by: Michael Walle <michael@walle.cc>

2014-02-04target-lm32: move model features to LM32CPUMichael Walle1-12/+17
This allows us to completely remove CPULM32State from DisasContext. Instead, copy the fields we need to DisasContext. Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Michael Walle <michael@walle.cc>
2014-02-04target-lm32: kill cpu_abort() callsMichael Walle1-32/+40
Instead of killing QEMU, translate instructions which are not available on the CPU model as a noop and issue a log message at translation time. On the real hardware CPU unknown opcodes results in undefined behaviour. These changes prepare the removal of CPULM32State from DisasContext.

2013-04-08hw: move headers to include/Paolo Bonzini1-1/+1
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-03-03gen-icount.h: Rename gen_icount_start/end to gen_tb_start/endPeter Maydell1-2/+2
The gen_icount_start/end functions are now somewhat misnamed since they are useful for generic "start/end of TB" code, used for more than just icount. Rename them to gen_tb_start/end.

2013-02-23qemu-log: Remove qemu_log_try_set_file() and its usersPeter Maydell1-2/+0
Remove the function qemu_log_try_set_file() and its users (which are all in TCG code generation functions for various targets). This function was added to abstract out code which was originally written as "if (!logfile) logfile = stderr;" in order that BUG: case code which did an unguarded "fprintf(logfile, ...)" would not crash if debug logging was not enabled. Since those direct uses of logfile have also been abstracted away into qemu_log() calls which check for a NULL logfile, there is no need for the target-* files to mess with the user's chosen logging settings.

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).
