Bruno Haible 0dfa3015 2019-12-22T09:32:07 count-leading-zeros: Assume that the compiler supports 'long long'. * lib/count-leading-zeros.h (count_leading_zeros_ll): Define unconditionally. * m4/count-leading-zeros.m4: Remove file. * modules/count-leading-zeros (Files): Remove it. (configure.ac): Don't invoke gl_COUNT_LEADING_ZEROS. * tests/test-count-leading-zeros.c (main): Test count_leading_zeros_ll unconditionally.
Bruno Haible 42254c0a 2019-03-09T20:32:25 Fix undefined behaviour. * lib/bitrotate.h (rotl16, rotr16, rotl8, rotr8): Case x to 'unsigned int', to avoid shift operations on 'int'. * lib/xmemdup0.c (xmemdup0): Don't invoke memcpy with a zero size. * tests/test-count-leading-zeros.c (main): Use a random number that has as many bits as TYPE, not only 2*15 or 2*31 bits. * tests/test-count-trailing-zeros.c (main): Likewise. * tests/test-count-one-bits.c (main): Likewise. * tests/test-memmem.c: Don't include "null-ptr.h". (main): Use zerosize_ptr() instead of null_ptr(). * modules/memmem-tests (Files): Remove tests/null-ptr.h.

Bruno Haible 57bac80c 2018-09-06T14:49:14 count-leading-zeros tests: Rely on limits-h module. * tests/test-count-leading-zeros.c (ULLONG_MAX): Remove fallback definition. * modules/count-leading-zeros-tests (Depends-on): Add 'limits-h'.

Eric Blake 0da76a94 2012-08-10T16:51:08 count-leading-zeros: new module I needed gcc's clz to determine the most significant bit of a number (useful for things like truncating to a power of 2), and was surprised it is not a standardized function (the opposite direction of finding the least significant bit is given by ffs). This borrows heavily from the design of the count-one-bits module. * modules/count-leading-zeros: New module. * m4/count-leading-zeros.m4: New file. * lib/count-leading-zeros.h: Likewise. * modules/count-leading-zeros-tests: New test. * tests/test-count-leading-zeros.c: New file. * MODULES.html.sh (Integer arithmetic functions): Document it.
