The AIX failure is real:
e.g.

FWIW I am separately testing a PR to update the CPU target for V8 on AIX to Power 9. I think (based on gcc -Q --help=target output) that that turns on -maltivec, so I could also add that to node.gypi for building Node.js (and not just V8) on AIX. But simdjson might need to detect whether altivec is enabled on Power for general use because without a -mcpu setting GCC 12 (which we currently use) on AIX doesn't enable -maltivec by default.

Here is the internal logic in simdjson:

// other code here
#elif defined(__PPC64__) || defined(_M_PPC64)
#define SIMDJSON_IS_PPC64 1
#if defined(__ALTIVEC__)
#define SIMDJSON_IS_PPC64_VMX 1
#endif // defined(__ALTIVEC__)

and this is used as follows...

#define SIMDJSON_IMPLEMENTATION_PPC64 (SIMDJSON_IS_PPC64 && SIMDJSON_IS_PPC64_VMX)

So we should only enable altivec when __ALTIVEC__ is defined.

Unfortunately, I do not have access to an AIX system. If you do, can you verify whether __ALTIVEC__ is defined?

Note that we can just disable the whole thing by passing SIMDJSON_IMPLEMENTATION_PPC64=0 at build time.

@richardlau To be clearer, there is no runtime dispatching when building simdjson on POWER systems. We only enable the optimized kernel when __ALTIVEC__ is defined (at compile time). Otherwise we use our non-optimized kernel.
