[PATCH] D107882: BPF: Enable frontend constant folding for VLA size

[Paul Chaignon via Phabricator via cfe-commits]

pchaigno added a comment.

I tested this patch by running it through Cilium's CI which compiles, loads, and validates the behavior of hundreds of slightly different BPF programs. The tests cover several different kernels and all three BPF instruction set extensions (mcpu={v1,v2,v3}). It did not generate invalid bytecode with the register R11 <https://reviews.llvm.org/source/libunwind/> anymore and the tests did not uncover any other regressions with this patch.
