Subject: [AVR] Do not kill the dest register for a pseudo instruction
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f23578fbc3fa1c096372b0a4fa3bb38b6d156027;p=llvm

[AVR] Do not kill the dest register for a pseudo instruction

It caused the register to later be dead, which would trigger a verifier
error.
