[PATCH] D110933: [RISCV] Add a test showing incorrect RVV stack alignment

[luxufan via Phabricator via llvm-commits]

StephenFan added a comment.

If this misalign problem does affect the correct executable of the program contain RVV stack object, and to fix it, the following two ways may make sense:

1. Deal with allocations of RVV vector object like variable sized object.
2. Change the RVV frame layout to what D93750 <https://reviews.llvm.org/D93750> did. Instead of calculating the total RVVStackSize and allocate them all at once, D93750 <https://reviews.llvm.org/D93750> will allocate the RVV stack objects one by one. Thus we can realign for every RVV stack object separately when it was allocating.
