Makefile.in (LIBGCC_DEPS): Add libgcc2.h.
* Makefile.in (LIBGCC_DEPS): Add libgcc2.h. * libgcc2.c (__clz_tab[], __popcount_tab[]): Set the fixed dimension of these arrays. * libgcc2.h (__clz_tab[], __popcount_tab[]): Add exports of these arrays. * longlong.h: Only provide a prototype for the __clz_tab[] array if this header has not been included from libgcc2.h. * config/stormy16/stormy16-lib2.c: Include libgcc2.h rather than defining own types. Provide prototypes for exported functions. Use the __clz_tab[] and __popcount_tab[] arrays provided by libgcc2.c. From-SVN: r104081
