Subject: RFR: Store cpu features in AOTCodeCache header
Message-ID: <He9B56IHjw-HusHrnRKwU51Nz_RYvaxfjaPrrH1aYaw=.94a0d16e-ab87-46f3-bbbd-d4b1db376185@github.com>

This is the initial version of storing cpu features in the AOTCodeCache to verify runtime env has the same cpu capabilities as the assembly env. It covers both x86 and aarch64.
AOTCodeCache header is updated to store the cpu features in arch-dependent form (although its same for currently supported architectures - x86 and aarch64).

It also fixes a bug - the `polling_page_vectors_safepoint_handler_blob` can be null if AVX is not present on a system. This causes crash as this blob's entry point is stored in the address table.
I came across this when I did the assembly run with -XX:UseAVX=0 option.

CRaC project has [a similar feature](https://docs.azul.com/core/crac/cpu-features). In comparison here I miss here some command line option to disable this comparison (`-XX:CPUFeatures=ignore`) as one may find some missing CPU feature not really important to run the restored code. It is intended more for debugging/development.

src/hotspot/cpu/aarch64/vm_version_aarch64.cpp line 797:

> 795: bool VM_Version::supports_features(void* features_buffer) {
> 796:   uint64_t features_to_test = *(uint64_t*)features_buffer;
> 797:   return (_features & features_to_test) == features_to_test;

Here you test whether the new machine has at least the same CPU features as the old (stored) machine. From our experience from [CRaC](https://docs.azul.com/core/crac/cpu-features) one should rather compare the features are equal. As some features presence affect ABI of the JIT-compiled code and if the new machine has such CPU features the newly JITted code will be incompatible with ABI of the stored code cache.

Could you provide more detail about your statement "some features presence affect ABI of the JIT-compiled code"?

Simply said if you store the compiled Java code on old CPU (almost no features) and then run it on new CPU (full features) then it will crash. It crashes when a newly compiled code calls the restored code or vice versa. If you disagree I can try to reproduce with Leyden, it was happening with CRaC.

@jankratochvil thanks for sharing your experience. It would be great if you can provide a reproducer.

It can be a future extension but Leyden may also find useful an equivalent of `-XX:CPUFeatures=generic` so that you can store the data on any machine and restore it also on any machine - limiting the CPU feature set in all runs to some reasonable minimum.

We have discussed such an option in dev team meetings. We are still considering what would be the most useful and/or usable model.

It crashes when a newly compiled code calls the restored code or vice versa. If you disagree I can try to reproduce with Leyden, it was happening with CRaC.

@jankratochvil I'm not disagreeing - merely wanting to see where CRaC goes wrong and why (noting that it is a slightly different circumstance to the AOT Cache case).

My preferred position would be that there /ought not/ to be any issues reusing code generated during the AOT Cache assembly phase in the absence of some given feature in combination with with code generated in a production run where that feature is present i.e. that that any incompatibility would constitute an error in the code generation scheme. I'd be very interested in any evidence you can provide to show that 1) such a code generation error exists or, worse, 2) my preference is unrealizable.

Leyden developers, please review

https://github.com/openjdk/jdk/pull/26082

This PR is a preliminary step for JDK-8350550: Preload classes from AOT 
cache during VM bootstrap, which will make sure all cached classes have 
already been loaded before any Java code is executed. This should make 
it easier to implement AOT compilation of Java methods.

Thanks!

Subject: Question about supporting aot on other platforms (RISC-V)
Message-ID: <CANOXDv=xSNTxvaFDq88gyXHsDG3yCc-JZYazDUgOxdASvnd_Yg@mail.gmail.com>

Hi,

I'm trying to apply changes related to aot on riscv (first step is
https://github.com/openjdk/jdk/pull/26101, also plan to apply further
changes in the future gradually).

As Andrew suggested in the pr, there will be more changes (especially
related to code save/restore) from leyden premain to mainline.
I went through the pr's and discussion of leyden, found out several changes
might be platform related:
1. Store cpu features in AOTCodeCache header (
https://github.com/openjdk/leyden/pull/84 ) (Open)
2. AOT code generation should support UseCompactObjectHeaders (
https://github.com/openjdk/leyden/pull/78 ) (committed into premain)

I think in the short future, these above pr's are going to get into
mainline. But I might overlook some pr's or discussions,
Besides of these above pr's, are there any other potential changes or
discussions I should pay attention to when I try to support aot on riscv?
I asked the questions to make sure after I integrate
https://github.com/openjdk/jdk/pull/26101, even if more leyden changes are
merged (including the above ones) into mainline, I can still make aot work
as expected on riscv quickly, rather than break aot things for a long time,
i.e. hope no surprise in the progress.

Thank you
-Hamlin
