2012-03-24target-alpha: Use noreturn marker in helper.h.Richard Henderson1-1/+1
Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-03-24target-alpha: Make use of fp_status.flush_inputs_to_zero.Richard Henderson1-3/+2
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 Henderson1-4/+4
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 Henderson1-0/+4
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.

2011-10-08target-alpha: Implement HALT IPR.Richard Henderson1-0/+1
Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Implement TLB flush primitives.Richard Henderson1-0/+3
Expose these via MTPR, more or less like the real HW does. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Rationalize internal processor registers.Richard Henderson1-2/+0
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>
2011-05-31target-alpha: Merge HW_REI and HW_RET implementations.Richard Henderson1-1/+0
Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Fix translation of PALmode memory insns.Richard Henderson1-17/+9
All of the "raw" memory accesses should be "phys" instead. Fix some confusion about argument ordering of the store routines. Fix the implementation of store-conditional. Delete the "alt-mode" helpers. Because we only implement two mmu modes, let /a imply user-mode unconditionally. Leave some combinations of virt access without permission checks as unimplemented. There are too many hoops through which to jump, and these insns will not be needed in the emulation palcode. Signed-off-by: Richard Henderson <rth@twiddle.net>
2010-04-27target-alpha: Implement cvtlq inline.Richard Henderson1-1/+0
It's a simple shift and mask sequence. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-27target-alpha: Implement rs/rc properly.Richard Henderson1-2/+0
This is a per-cpu flag; there's no need for a spinlock of any kind. We were also failing to manipulate the flag with $31 as a target reg and failing to clear the flag on execution of a return-from-interrupt instruction.

2010-04-10target-alpha: Implement cvtql inline.Richard Henderson1-4/+0
It's a simple mask and shift sequence. Also, fix a typo in the actual masks used. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-10target-alpha: Add flags markups to helpers.h.Richard Henderson1-92/+92
Almost all alpha helpers are at least TCG_CALL_CONST and a fair few are also TCG_CALL_PURE. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-02-28target-alpha: Implement IEEE FP qualifiers.Richard Henderson1-3/+18
IEEE FP instructions are split up so that the rounding mode coming from the instruction and exceptions (both masking and delivery) are handled external to the base FP operation. FP exceptions are properly raised for non-finite inputs to instructions that do not indicate software completion. A shortcut is applied if CONFIG_SOFTFLOAT_INLINE is defined at the top of translate.c: data is loaded and stored into FP_STATUS directly instead of using the functional interface defined by "softfloat.h".

2009-12-17target-alpha: Implement fp branch/cmov inline.Richard Henderson1-7/+0
The old fcmov implementation had a typo: - tcg_gen_mov_i64(cpu_fir[rc], cpu_fir[ra]); which moved the condition, not the second source, to the destination. But it's also easy to implement the simplified fp comparison inline. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-04-10target-alpha: remove amask helperaurel321-1/+0
