target-alpha: Rationalize internal processor registers.

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....

target-alpha: Tidy exception constants.

There's no need to attempt to match EXCP_* values with PALcode entry
point offsets. Instead, compress all the values to make for more
efficient switch statements within QEMU.

We will be doing TLB fill within QEMU proper, not within the PALcode,...

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.

Format errors were fixed in
  • target-i386/helper.c
  • target-mips/translate.c
  • target-ppc/translate.c

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.

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 fields
are stored in <softfloat.h> format for convenience during
regular 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 recognise
that 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_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...

of temps; this flag should be set when the tcg_gen_qemu_store callback...
