Enable cross-block assertion prop by default.

The failures above are for the release-mode debug info testing. With cross-block we remove the store at IL offset 0 and this causes the validation to fail.

Going to just add another exemption here... I'm surprised something downstream doesn't catch this already (basically x + 0 => x), but without an immediate zero.

Looks like a bug has crept in, possibly from the JTRUE assertions.

jit-experimental failure was that the fgEntryBB was getting emtpy-merged, in cases where other flow optimizations more or less remove all the other blocks save one, and so fgBBcount was off by one going into morph. This currently can only happen with OSR stress.

FYI @dotnet/jit-contrib

Latest diffs. Main impact here is a code size improvement; TP results are mixed but "average" out to about zero.

LGTM, very nice to see this enabled. I kicked off a Fuzzlyn run with it enabled.

I have perf lab data too but so far it's indistinguishable from noise; I almost suspect the feature is not getting enabled,

The Fuzzlyn runs will hit #95318 so we'll probably have to do a bit digging to see if there is anything else.

I only see the unexpected small type asserts.

I only see the unexpected small type asserts.

The number of examples found does not match up with the number of those assertion occurrences... But I'm not totally sure whether those counts are accurate or not given the number of examples found.

#95249 was merged now so I'm going to rerun Fuzzlyn to be sure.

Do those runs merge up or do we need a new merge from main?

It merges, the run is happening on 4cd4b07 that has @EgorBo's commit.
