Revision 179760 changed casesi so that the libgcc code to read from the lookup table by means of __tablejump2__ is used unconditionally, i.e. does no more depend on -mcall-prologues. Consequently, casesi costs no more depend on -mcall-prologues since r179769 and are cheaper. This patch adjusts avr_case_values_threshold and set it to 7. Johann * config/avr/avr.c (avr_case_values_threshold): Return 7.
