...In our out-of-tree target we've been doing some bundling before register allocation for quite some time now, and last night a new problem popped up. What the fix should be depends on if this bundle is legal or not: BUNDLE %vreg39<imp-def,dead> * %vreg39:hiAcc<def> = mv_ar16_ar16_lo16In32 %vreg37 [...] %vreg39 isn't used after the bundle so the dead-marking in the BUNDLE is correct. However, the def in the actual bundled instruction defining %vreg39 is not marked with dead. Is the above bundle ok or not? When the register allocator later tries to spill/reload %vreg3...
