...a SimpllfyCfg pass is reached, of which there are few in the pipeline. One example is https://github.com/rust-lang/rust/issues/44041 - the branch conditions are found by loop unrolling, but the `br i1 false` instruction leaks to codegen. Another example is https://github.com/rust-lang/rust/issues/45466. In that case, induction variable simplification discovers that an integer overflow check is unnecessary, but the remaining `br i1 false` still blocks the following LoopIdiomRecognize pass and prevents the loop from being optimized to a memset. While it is possible to have point-fixes for both pr...

Hi, Apologies in advance for any breaches of netiquette, I couldn't find any guidelines about submission to this forum but I'd be grateful for your help on something. My /boot filesystem is being remounted shortly after start-up as read-only. I get the following messages... journal_bmap_Ra7a5f568: journal block not found at offset 12 on ide0(3,1) Aborting journal on device ide0(3,1)
