target-alpha: Fix integer overflow checking insns We need to write the result to the destination register before raising any exception. Thus inline the code for each insn, and check for any exception after we're done. Reported-by: Al Viro <viro@ZenIV.linux.org.uk> Signed-off-by: Richard Henderson <rth@twiddle.net>

target-alpha: Add high-resolution access to wall clock and an alarm. 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. Signed-off-by: Richard Henderson <rth@twiddle.net>

tcg: Remove stray semi-colons from target-*/helper.h 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.

target-alpha: Move alarm to vm_clock 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.
