From the point of view of register assignment, byval parameters are ignored: a byval parameter is not going to be assigned to a register, and it will not affect the assignments of subsequent parameters. When matching registers with parameters in the bit tracker, make sure to skip byval parameters before advancing the registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@278375 91177308-0d34-0410-b5e6-96231b3b80d8
