This is about twice as fast as the current hash, and removes the need for double hashing (improving locality of reference). The hash function is based on Bob Jenkins' design, slightly adapted wherever Make needs to hash NUL-terminated strings. The old hash function is kept for case-insensitive hashing. This saves 8.5% on QEMU's no-op build (from 12.87s to 11.78s). * configure.ac: Check endianness. * hash.c (rol32, jhash_mix, jhash_final, JHASH_INITVAL, sum_get_unaligned_32, jhash): New. * hash.h (STRING_HASH_1, STRING_N_HASH_1): Use jhash. (STRING_HASH_2, STRING_N_HASH_2): Return a dummy value. (STRING_N_COMPARE, return_STRING_N_COMPARE): Prefer memcmp to strncmp.

Test the behavior of the .INTERMEDIATE special target.

Create a makefile where a file would not normally be considered
|
|
intermediate, then specify it as .INTERMEDIATE. Build and ensure it's
|
|
deleted properly. Rebuild to ensure that it's not created if it doesn't
|
|
exist but doesn't need to be built. Change the original and ensure
|
|
that the intermediate file and the ultimate target are both rebuilt, and
|
|
that the intermediate file is again deleted.
