If anyone has any objections, please let me know. ------------------ From: Maciej W. Rozycki commit 1f4edde422961397cf4470b347958c13c6a740bb upstream. Use the more accurate `sigill_r2r6' name for the label used in the case of sending SIGILL in the absence of the instruction emulator for an earlier ISA level instruction that has been removed as from the R6 ISA, so that the `sigill_r6' name is freed for the situation where an R6 instruction is not supposed to be interpreted, because the executing processor does not support the R6 ISA.
