Hi Andrew and all,
Since we are getting ready to propose Vector API target to JDK 16 [1]. I
have regenerated webrev of aarch64 backend parts from panama repo, which
has been rebased to jdk/jdk very recently, by:
$ hg update vector-unstable && hg diff -r default > all.patch
$ grep "diff -r"
Thank you Erik!
Regards,
Ningsheng

Hi Vladimir,
Thanks for pointing out this. Yes, I missed that change in shared code.
I've regenerated the webrev, with GensrcAdlc.gmk file change included:
http://cr.openjdk.java.net/~njian/vectorapi/8223347-integration/aarch64-webrev.01/
Also add build-dev.
Thanks,

Thank you @nick-arm for the review! All your comments have been addressed.

Could any reviewer please help to review AArch64 changes in this patch?
@theRealAph @adinn @nick-arm ?
The AArch64 changes include:
1. SVE scalable predicate register allocation support
2. SVE backend

Fixed in the new commit. Thanks to @PaulSandoz for integrating the fix!

This is the REDO of JDK-8269559 and JDK-8275448. Those two backouts finally
turned to be some system zlib issue in AArch64 macOS, and is not related to the
patch itself. See [1][2] for details.
This patch is generally the same as JDK-8275448, which uses SVE to optimize
string_compare

`UsePopCountInsturction` is always true in AArch64. @XiaohongGong removed the
`predicate` in aarch64 rules, and I think we can even remove the option
19 matches
