Paul Eggert 82d259c2 2012-11-20T22:25:05 count-leading-zeros: better 'inline' * lib/count-leading-zeros.c: New file. * lib/count-leading-zeros.h (COUNT_LEADING_ZEROS_INLINE): New macro. Replace all uses of 'static inline' with it. Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. * m4/count-leading-zeros.m4 (gl_COUNT_LEADING_ZEROS): Do not require AC_C_INLINE. * modules/count-leading-zeros (Files, lib_SOURCES): Add lib/count-leading-zeros.c. (Depends-on): Add extern-inline.
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.
