LiveInterval error with 2 dead defs
...ted patch caused a compilation problems on Hexagon: https://bugs.llvm.org/show_bug.cgi?id=43302
The splitting of a live interval should not be done automatically upon creation. Calling LIS->getInterval(Reg) should not go around changing the code behind the scenes.
There is already a function “splitSeparateComponents” that does that. It should be added where it’s missing.

LiveInterval error with 2 dead defs
Hi,
I’m hitting a machine verifier error in a trivial testcase which I don’t understand. There are 2 dead defs of the same register:
---
name: multiple_connected_compnents_dead
tracksRegLiveness: true
body: |
bb.0:
dead %0:vgpr_32 = V_MOV_B32_e32 0, implicit $exec
dead %0:vgpr_32 = V_MOV_B32_e32 1, implicit $exec
...
The live intervals look OK to me with 1 valno
