Modified Files: src/usr.bin/make: var.c Log Message: make: replace enum bit-set with bit-field No functional change. The generated code from GCC 5.5 is very similar. On x86_64, memory access is no longer in 32-bit units but in 8-bit units since only the first few bits are actually used. The bit patterns are the same as before, so if there is any difference in performance, GCC should have chosen the more efficient variant all along. In a previous experiment, the code size increased a lot, surprisingly.
