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

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

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. http://cr.openjdk.java.net/~goetz/webrevs/8086069-call_conv/webrev.01/

Best regards, Goetz
