2012-03-24target-alpha: Make use of fp_status.flush_inputs_to_zero.Richard Henderson
This softfp feature post-dates the last major update to the Alpha fpu translation. We can make use of this to eliminate at least one helper function that was performing this operation by hand. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-03-24target-alpha: Move memory helpers to mem_helper.c.Richard Henderson
This completes the transition away from AREG0. This patch must be last because it requires CONFIG_TCG_PASS_AREG0 set too. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-10-08target-alpha: Add high-resolution access to wall clock and an alarm.Richard Henderson
The alarm is a fully general one-shot time comparator, which will be usable under Linux as a hrtimer source. It's much more flexible than the RTC source available on real hardware. The wall clock allows the guest access to the host timekeeping. Much like the KVM wall clock source for other guests. Both are accessed via the PALcode Cserve entry point.

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>
2011-07-12target-alpha, target-ppc: Remove unnecessary setjmp.h includePeter Maydell
Remove the include of setjmp.h from the cpu.h of target-alpha and target-ppc. This is unnecessary because cpu-defs.h already includes this header; this change brings these two targets into line with all the rest.

2011-05-31target-alpha: Implement more CALL_PAL values inline.Richard Henderson
In particular, SWPIPL is used quite a lot by the Linux kernel. Doing this inline makes it significantly easier to step through without the debugger getting confused by the mode switch. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Disable interrupts properly.Richard Henderson
Interrupts are disabled in PALmode, and when the PS IL is high enough. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: All ISA checks to use TB->FLAGS.Richard Henderson
We had two different methods in use, both of which referenced ENV, and neither of which indicated to the generic code when different compilation modes are not compatible. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-05-31target-alpha: Add various symbolic constants.Richard Henderson
The EXC_M_* constants were being set for the EV6, not as set for the Unix kernel entry point. Use PS_USER_MODE instead of hard-coding access to the PS register. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Use do_restore_state for arithmetic exceptions.Richard Henderson
This gets the PC right after an arithmetic exception. Also tidies the code in the TLB fault handlers to use common code. Signed-off-by: Richard Henderson <rth@twiddle.net>

Introduce and use arith_excp, filling in the trap_arg[01] IPRs. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Tidy exception constants.Richard Henderson
There's no need to attempt to match EXCP_* values with PALcode entry point offsets. Instead, compress all the values to make for more efficient switch statements within QEMU. We will be doing TLB fill within QEMU proper, not within the PALcode, so all of the ITB/DTB miss, double fault, and access exceptions can be compressed to EXCP_MMFAULT. Compress all of the EXCP_CALL_PAL exceptions into one. Use env->error_code to store the specific entry point. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Enable the alpha-softmmu target.Richard Henderson
With all of the pre-existing code that would not compile gone, this is the earliest point at which the target can be enabled. There is no machine defined yet, so this will crash on startup. Enable the target anyway, to make sure that further compilation problems do not creep back in. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Rationalize internal processor registers.Richard Henderson
Delete all the code that tried to emulate the real IPRs of some unnamed CPU. Replace those with just 3 slots that we can use to communicate trap information between the helper functions that signal exceptions and the OS trap handler. Signed-off-by: Richard Henderson <rth@twiddle.net>
