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 .SECONDARY special target.

Create a makefile where a file would not normally be considered

intermediate, then specify it as .SECONDARY. Build and note that it's

not automatically deleted. Delete the file. 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 secondary file and the ultimate

target are both rebuilt, and that the secondary file is not deleted.
