2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson
Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-10-10tcg: Remove stray semi-colons from target-*/helper.hRichard Henderson
During GEN_HELPER=1, these are actually stray top-level semi-colons which are technically invalid ISO C, but GCC accepts as an extension. If we added enough __extension__ markers that we could dare use -Wpedantic, we'd see warning: ISO C does not allow extra ‘;’ outside of a function This will become a hard error in the next patch, wherein those ; will appear in the middle of a data structure.

2013-08-16target-alpha: Use goto_tb in call_palRichard Henderson
With appropriate flushing when the PALBR changes, the target of a CALL_PAL is so predictable we can chain to it. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-16target-alpha: Implement call_pal without an exceptionRichard Henderson
The destination of the call_pal, and the cpu state, is very predictable; there's no need for exiting the cpu loop. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-07-18target-alpha: Move alarm to vm_clockRichard Henderson
Basing the alarm off the rtc_clock was silly. It leads to horrible spinning in the guest after being suspended and resumed, as it tries to catch up with lost ticks. This requires adding an accessor for reading the vm_clock too. Signed-off-by: Richard Henderson <rth@twiddle.net>

2012-10-28target-alpha: rename helper flagsAurelien Jarno

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.

2011-05-31target-alpha: Fix translation of PALmode memory insns.Richard Henderson
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 rs/rc properly.Richard Henderson
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.

2010-02-28target-alpha: Implement IEEE FP qualifiers.Richard Henderson
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 Henderson
