target-alpha: Implement RPCC.

A minimal implementation that more or less corresponds to the
user-level version used by target-i386. More hoops will want
to be jumped through when alpha gets system-level emulation.

target-alpha: Fix load-locked/store-conditional.

Use an exception plus start_exclusive to implement the compare-and-swap.
This follows the example set by the MIPS and PPC ports.

Move TARGET_PHYS_ADDR_SPACE_BITS to target-*/cpu.h.

Removes a set of ifdefs from exec.c.

Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other
than Alpha. This will be used for page_find_alloc, which is
supposed to be using virtual addresses in the first place....

alpha-linux-user: Implement signals.

Move userland PALcode handling into linux-user main loop so that
we can send signals from there. This also makes alpha_palcode.c
system-level only, so don't build it for userland. Add defines
for GENTRAP PALcall mapping to signals....

target-alpha: Split up FPCR value into separate fields.

The fpcr_exc_status, fpcr_exc_mask, and fpcr_dyn_round fields
are stored in <softfloat.h> format for convenience during
regular execution.

Revert the addition of float_exception_mask to float_status,...

target-alpha: Reduce internal processor registers for user-mode.

The existing set of IPRs is totally irrelevant to user-mode emulation.
Indeed, they most are irrelevant to implementing kernel-mode emulation,
and would only be relevant to PAL-mode emulation, which I suspect that...

target-alpha: Clean up arithmetic traps.

Replace the EXCP_ARITH_OVERFLOW placeholder with the complete
set of bits from the EXC_SUM IPR. Use them in the existing
places where we raise arithmetic exceptions.

target-alpha: Fixes for alpha-linux syscalls.

1. Add correct definitions of error numbers.
2. Implement SYS_osf_sigprocmask
3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL.

This last requires exposing the FPCR value to do_syscall.
Since this value is actually split up into the float_status,...

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...

cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signal

handle_cpu_signal is very nearly copy-paste code for each target, with a
few minor variations. This patch sets up appropriate defaults for a
generic handle_cpu_signal and provides overrides for particular targets...

The _exit syscall is used for both thread termination in NPTL applications,
and process termination in legacy applications. Try to guess which we want
based on the presence of multiple threads.

Also implement locking when modifying the CPU list.
