* bitmap.h: Add explanation of sparse set as linked-list bitmap.
* sbitmap.h: Add explanation about non-sparse sets as simple bitmap. (TEST_BIT): Make a static inline function for stronger type checking. (SET_BIT): Don't handle sbitmaps with popcount. (RESET_BIT): Likewise. (SET_BIT_WITH_POPCOUNT): New, like SET_BIT but with popcount. (RESET_BIT_WITH_POPCOUNT): New, like RESET_BIT but with popcount. * ebitmap.c (ebitmap_clear_bit): Use SET_BIT_WITH_POPCOUNT and RESET_BIT_WITH_POPCOUNT on wordmask bitmaps. (ebitmap_set_bit, ebitmap_and_into, ebitmap_and, ebitmap_ior_into, ebitmap_and_compl_into, ebitmap_and_compl): Likewise. * sparseset.h: Add explanation of sparse set representation. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@189888 138bc75d-0d04-0410-961f-82ee72b054a4
