[aarch64-port-dev ] Ping: RFR(M): 8086069: Adapt runtime calls to recent intrinsics to pass ints as long

[Lindenmaier, Goetz]

Hi,

Could someone please have a look at this change?

I had a look whether I can push the functionality down to make_runtime_call().
This would simplify matters a lot. But as the TypeFunc is hashed, I can not
change it any more in make_runtime_call().

@aarch-people: I saw you have CCallingConventionRequiresIntsAsLongs set.
Could you please check whether this breaks your intinsics, e.g., multiplyToLen?
(We assure in sharedRuntime_ppc.cpp, c_calling_convention() that no INT types
end up there.)

Thanks,
  Goetz

Subject: RFR(M): 8086069: Adapt runtime calls to recent intrinsics to pass ints as long

Hi,

we are working on porting the recently* added intrinsics to PPC.  As these use
runtime calls, the calls must obey to the platform ABI, which requires that ints
are passed as longs.

We made a similar change in "8024342: PPC64 (part 111): Support for C calling
conventions that require 64-bit ints."  It adapts the calls if
CCallingConventionRequiresIntsAsLongs is set.

This change adapts the calls to multiplyToLen, CRC32, AES, SHA accordingly.

Please review this change.  I please need a sponsor.

Best regards,
