https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112358 --- Comment #7 from Jeffrey A. Law --- It could well be the case that the threader could transform this code to eliminate the unexecutable path, but that it wasn't deemed profitable, thus leaving a path in the IL that will never occur at runtime

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116283 --- Comment #1 from Jeffrey A. Law --- Code is a bit nonsensical in that it masks a shift by a crazy value (3629), but the underlying bug is real. Ultimately we're going to rely on the fact that hardware truncates the count (mask with 0x3f) and

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116282 --- Comment #2 from Jeffrey A. Law --- I haven't fully debugged, but I strongly suspect this is a case where matching is inconsistent before/after LRA due to the paths through the constant synthesis code which check if we can create new pseudos.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116244 --- Comment #3 from Jeffrey A. Law --- Adjusting subreg_regno isn't going to work. reload depends on it producing "bogus" results to then trigger reloading inner parts of the subreg expressions. Adjusting alter_reg might be an option.

[Bug target/116236] [LRA] [M68K] ICE insn does not satisfy its constraints

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116236 --- Comment #8 from Jeffrey A. Law --- If you have a case where a pseudo register is normally valid, but a MEM would not be valid. Then you reject that case when strict is on and the pseudo did not get a hard register.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116236 --- Comment #11 from Jeffrey A. Law --- In general I would think rejecting is right way to go under the general guidance of making the predicates and such match what the underlying hardware can actually do. So for example, if we we have (mem (r
