Subject: runtime: add ABIInternal to strhash and memhash on ppc64x
X-Git-Tag: go1.18beta1~1058
X-Git-Url: http://www.git.cypherpunks.su/?a=commitdiff_plain;h=7983830423ca0017dc5d990532e28df13862dc2d;p=gostls13.git

runtime: add ABIInternal to strhash and memhash on ppc64x

In testing the register ABI changes I found that the benchmarks
for strhash and memhash degraded unless I marked them as
ABIInternal. This fixes that.
