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: Fix float32_to_s vs zero exponent.

There was a bug in float32_to_s that incorrectly mapped a zero exponent
to 0x38. This meant 0.0f != 0. At the same time, fix a generic type
punning bug in helper_memory_to_s and helper_s_to_memory.

target-alpha: Implement fp branch/cmov inline.

The old fcmov implementation had a typo:
- tcg_gen_mov_i64(cpu_fir[rc], cpu_fir[ra]);
which moved the condition, not the second source, to the destination.

But it's also easy to implement the simplified fp comparison inline....
