Portability fixes for bitsets; this also avoids several GCC
|
||||||
|
warnings.
|
||||||
|
|
||||||
|
* lib/abitset.c: Include <stddef.h>, for offsetof.
|
||||||
|
* lib/lbitset.c: Likewise.
|
||||||
|
|
||||||
|
* lib/abitset.c (abitset_bytes): Return a size that is aligned
|
||||||
|
properly for vectors of objects. Do not assume that adding a
|
||||||
|
header size to a multiple of a word size yields a value that is
|
||||||
|
properly aligned for the whole union.
|
||||||
|
* lib/bitsetv.c (bitsetv_alloc): Likewise.
|
||||||
|
|
||||||
|
* lib/bitset_stats.c (bitset_stats_bytes): Adjust to new,
|
||||||
|
unique names for structures.
|
||||||
|
* lib/ebitset.c (ebitset_bytes): Likewise.
|
||||||
|
* lib/lbitset.c (lbitset_bytes): Likewise.
|
||||||
|
|
||||||
|
* lib/abitset.c (abitset_ones, abitset_zero, abitset_empty_p,
|
||||||
|
abitset_copy1, abitset_not, abitset_equal_p, abitset_subset_p,
|
||||||
|
abitset_disjoint_p, abitset_and, abitset_and_cmp, abitset_andn,
|
||||||
|
abitset_andn_cmp, abitset_or, abitset_or_cmp, abitset_xor,
|
||||||
|
abitset_xor_cmp, abitset_and_or, abitset_and_or_cmp,
|
||||||
|
abitset_andn_or, abitset_andn_or_cmp, abitset_or_and,
|
||||||
|
abitset_or_and_cmp, abitset_copy): Supply prototype decls,
|
||||||
|
to improve the type-checking that GCC can do.
|
||||||
|
* lib/bitset.c (bitset_op4_cmp): Likewise.
|
||||||
|
* lib/bitset_stats.c (bitset_stats_count,
|
||||||
|
bitset_stats_empty_p, bitset_stats_ones, bitset_stats_zero,
|
||||||
|
bitset_stats_copy, bitset_stats_disjoint_p,
|
||||||
|
bitset_stats_equal_p, bitset_stats_not, bitset_stats_subset_p,
|
||||||
|
bitset_stats_and, bitset_stats_and_cmp, bitset_stats_andn,
|
||||||
|
bitset_stats_andn_cmp, bitset_stats_or, bitset_stats_or_cmp,
|
||||||
|
bitset_stats_xor, bitset_stats_xor_cmp, bitset_stats_and_or,
|
||||||
|
bitset_stats_and_or_cmp, bitset_stats_andn_or,
|
||||||
|
bitset_stats_andn_or_cmp, bitset_stats_or_and,
|
||||||
|
bitset_stats_or_and_cmp): Likewise.
|
||||||
|
* lib/lbitset.c (lbitset_and, lbitset_and_cmp, lbitset_andn,
|
||||||
|
lbitset_andn_cmp, lbitset_or, lbitset_or_cmp, lbitset_xor,
|
||||||
|
lbitset_xor_cmp, lbitset_empty_p, lbitset_ones, lbitset_not,
|
||||||
|
lbitset_subset_p, lbitset_disjoint_p, debug_lbitset): Likewise.
|
||||||
|
|
||||||
|
* lib/abitset.h: Include bitset.h, not bbitset.h.
|
||||||
|
* lib/ebitset.h: Likewise.
|
||||||
|
* lib/lbitset.h: Likewise.
|
||||||
|
|
||||||
|
* lib/bbitset.h: (enum_bitset_ops, enum_bitset_type): New types.
|
||||||
|
All instances of parameters of type enum bitset_opts are now of
|
||||||
|
type enum_bitset_opts, to conform to the C Standard, and similarly
|
||||||
|
for enum_bitset_type.
|
||||||
|
* lib/ebitset.c (enum_ebitset_find_mode): Likewise.
|
||||||
|
* lib/lbitset.c (enum_lbitset_find_mode): Likewise.
|
||||||
|
|
||||||
|
Do not use "struct bitset_struct" to mean different things in
|
||||||
|
different modules. Not only is this confusing, it violates
|
||||||
|
the C Standard, which requires that structure types in different
|
||||||
|
modules must be compatible if one is to be passed to the other.
|
||||||
|
* lib/bbitset.h (bitset): Now points to a union, not to a struct.
|
||||||
|
All instances of "struct bitset_struct *" replaced with "bitset".
|
||||||
|
* lib/bitset.h (struct bitset_struct): Remove, replacing with....
|
||||||
|
(union bitset_union, struct abitset_struct, struct ebitset_struct,
|
||||||
|
struct lbitset_struct, struct bitset_stats_struct): New types.
|
||||||
|
All uses of struct bitset_struct changed to union bitset_union,
|
||||||
|
etc.
|
||||||
|
* lib/abitset.c (struct abitset_struct, abitset,
|
||||||
|
struct bitset_struct): Remove.
|
||||||
|
* lib/bitset_stats.c (struct bitset_stats_struct, bitset_stats,
|
||||||
|
struct bitset_struct): Remove.
|
||||||
|
* lib/ebitset.c (struct ebitset_struct, ebitset, struct
|
||||||
|
bitset_struct): Remove.
|
||||||
|
* lib/lbitset.c (struct lbitset_struct, lbitset, bitset_struct):
|
||||||
|
Likewise.
|
||||||
|
|
||||||
|
Do not call a function of type T using a call that assumes the
|
||||||
|
function is of a different type U. Standard C requires that a
|
||||||
|
function must be called with a type that is compatible with its
|
||||||
|
definition.
|
||||||
|
* lib/bbitset.h (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
|
||||||
|
New decls.
|
||||||
|
* lib/bitset.c (bitset_and_or_, bitset_andn_or_, bitset_or_and_):
|
||||||
|
New functions.
|
||||||
|
* lib/ebitset.c (PFV): Remove.
|
||||||
|
* lib/lbitset.c (PFV): Likewise.
|
||||||
|
* lib/ebitset.c (ebitset_and, ebitset_andn, ebitset_or,
|
||||||
|
ebitset_xor, ebitset_copy, ebitset_ones, ebitset_empty_p): New
|
||||||
|
decls.
|
||||||
|
(ebitset_and, ebitset_andn, ebitset_or, ebitset_xor): New functions.
|
||||||
|
(ebitset_vtable): Use them.
|
||||||
|
* lib/lbitset.c (lbitset_and, lbitset_andn, lbitset_or,
|
||||||
|
lbitset_xor): New functions.
|
||||||
|
(lbitset_vtable): Use them.
|
||||||
|
|
||||||
|
* lib/bitset.h (bitset_next, bitset_prev, bitset_only_set_p):
|
||||||
|
Declare.
|
||||||
|
|
||||||
|
* lib/bitsetv.c (bitsetv_alloc): Add a cast to (void *) to avoid a
|
||||||
|
GCC warning.
|
||||||
|
* lib/lbitset.c (LBITSET_CURRENT1): Likewise.
|
||||||
|
Use offsetof, for simplicity.
