This test case is much too big. Can you try running it through llvm-reduce MIR handling? That will likely remove most of the cruft. Then you can delete the IR and registers sections, and run through -run-pass=none to do some additional cleanups

Tried llvm-reduce, still 5000+ lines of mir. I'll try to simplify LLVM IR manually(like reducing the dimension of the vector)...

Thanks @arsenm , most of the 5000+ lines are virtregs, I've removed them.

Can drop most of these fields (running with -simplify-mir -run-pass=none will also do that)

-run-pass=none will compact these numbers

Can drop the section too, the uses have the inline class specifiers

Nit (feel free to ignore): there don't seem to be any stack accesses here. Do we need these?
Demonstrate `IMPLICIT_DEF implicit-def ...` can be generated after coalescing on PPC.
Demonstrate
IMPLICIT_DEF implicit-def ...can be generated after coalescing on PPC.The case is reduced from failure in #75570. The failure is triggered after #75271 .
