target-alpha: Rationalize internal processor registers.
Delete all the code that tried to emulate the real IPRs of someunnamed CPU. Replace those with just 3 slots that we can use tocommunicate trap information between the helper functions thatsignal exceptions and the OS trap handler....
target-alpha: Tidy exception constants.
There's no need to attempt to match EXCP_* values with PALcode entrypoint offsets. Instead, compress all the values to make for moreefficient switch statements within QEMU.
We will be doing TLB fill within QEMU proper, not within the PALcode,...
target-alpha: Implement do_interrupt for system mode.
Signed-off-by: Richard Henderson <rth@twiddle.net>
target-alpha: Swap shadow registers moving to/from PALmode.
target-alpha: Remove partial support for palcode emulation.
This code does not work, and will be replaced by a bios image.
target-xxx: Use fprintf_function (format checking)
fprintf_function uses format checking with GCC_FMT_ATTR.

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.

alpha: add missing 'break', spotted by clang analyzer

Remove cpu_get_phys_page_debug from userspace emulation
cpu_get_phys_page_debug makes no sense for userspace emulation, so remove it.

target-alpha: Split up FPCR value into separate fields.
The fpcr_exc_status, fpcr_exc_mask, and fpcr_dyn_round fieldsare stored in <softfloat.h> format for convenience duringregular execution.
Revert the addition of float_exception_mask to float_status,...
Fix incorrect exception_index use
env->exception_index should be cleared with -1, not 0.

target-alpha: Fix compiler warning for gcc-4.3 (and older)
"Old" compilers obviously are not able to recognisethat all cases are handled here:
qemu/target-alpha/helper.c:70: error: ‘round_mode’ may be used uninitialized in this function
A small modification helps the compiler to do its jobs....
target-alpha: Fixes for alpha-linux syscalls.
1. Add correct definitions of error numbers.2. Implement SYS_osf_sigprocmask3. 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. Somethinglike this must be presented on the list first so people can provide input...
Get rid of _t suffix
Some not so obvious bits, slirp and Xen were left alone for the timebeing.

Update to a hopefully more future proof FSF address
Update FSF address in GPL/LGPL boilerplate
The attached patch updates the FSF address in the GPL/LGPL boilerplatein most GPL/LGPLed files, and also in COPYING.LIB.

target-alpha: fix locked loads/stores
Fix reading of cpu_lock in gen_qemu_stql_c, original patch from LaurentDesnogues.
A new flag was added to gen_store_mem to allocate local temps insteadof temps; this flag should be set when the tcg_gen_qemu_store callback...
