Putting AX functions from AXVoice.h in an anonymous namespace does
successfully prevent compilers from merging those functions and
allows us to avoid ODR violations.
However, tools such as gdb still mix up AX GC and AX Wii functions
and variables because those have the exact same symbol names.
This can be fixed by using inline namespaces which are transparent
at the source code level but forces AX GC and AX Wii symbols to be
different.
Passing a width of 64 and registers encoded as double to
DUP resulted in an invalid instruction. The registers should
be encoded as quads in this situation.
Fixes https://bugs.dolphin-emu.org/issues/12575.
Manually encoding and decoding logical immediates is error-prone.
Using ORRI2R and friends lets us avoid doing the work manually,
but in exchange, there is a runtime performance penalty. It's
probably rather small, but still, it would be nice if we could
let the compiler do the work at compile-time. And that's exactly
what this commit does, so now I have no excuse for trying to
manually write logical immediates anymore.
If a branch is unconditional, its target should not be in farcode,
since that defeats the purpose of farcode (putting seldom executed
code in farcode to keep it out of the icache when possible).
Fixes a 58698b8380 regression. (The EXCEPTION_EXTERNAL_INT
immediate being wrong meant that we never took the branch,
masking the problem of the MSR.EE immediate being wrong...)
In cases where we already know that there is an exception,
either because we just checked for it or because we were
the ones that generated the exception to begin with,
we can skip the branch inside WriteExceptionExit.
Unlike most constants we emit in JitArm64, these constants are
*not* inherent to the CPU we're emulating, and can have whatever
values we want. Let's handle them more robustly, in case we
decide to change their values in the future.
