Comments
Generating the wrong insn for pointer comparison in intrinsic (on SPARC). Exposed by serial GC relocating buffers (big-numbers) to high memory region with msb (sign bit) set in address.

Please, run pre-integration testing before push.

I am passing this one on to Patric who implemented JDK-8167199 "Add C2 SPARC intrinsic for BigInteger::multiplyToLen() method"

Issue reproducible in reported Solaris-Sparc machine, using the same test build- with in 20 iterations of following run - $ javac TestMultiplyToLen.java $ java -XX:MaxRAMPercentage=2 -server -XX:+UseSerialGC -XX:+CreateCoredumpOnCrash -XX:-TieredCompilation -Xbatch -XX:CompileCommand=exclude,compiler.intrinsics.bigInteger.TestMultiplyToLen::main -XX:CompileCommand=option,compiler.intrinsics.bigInteger.TestMultiplyToLen::base_multiply,ccstr,DisableIntrinsic,_multiplyToLen -XX:CompileCommand=option,java.math.BigInteger::multiply,ccstr,DisableIntrinsic,_multiplyToLen -XX:CompileCommand=inline,java.math.BigInteger::multiply TestMultiplyToLen (so far no failure in my local Linux-x64)

initial ILW = single compiler/intrinsics/bigInteger/TestMultiplyToLen.java test failure; seems intermittent, for now in solaris-sparc only; no workaround = MMH = P3 This TestMultiplyToLen.java test failure reported seems to be intermittent failure, so far reported only with solaris-sparc. (As of now not able to reproduce the failure with simple test run using the same test build tools in the same remote test machine)
