Module dvec

Compiler implementation of the D programming language.

Simple bit vector implementation.


vec_and(v1, v2, v3) Compute v1 = v2 & v3.
vec_andass(v1, v2) Compute v1 &= v2.
vec_calloc(numbits) Allocate a vector given # of bits in it. Clear the vector.
vec_clear(v) Clear vector.
vec_clearbit(b, v) Clear bit b in vector v.
vec_clearextrabits(v) Clear any extra bits in vector.
vec_clone(v) Allocate copy of existing vector.
vec_copy(to, from) Copy vector.
vec_disjoint(v1, v2) Return 1 if (v1 & v2) == 0
vec_equal(v1, v2) Return 1 if vectors are equal.
vec_free(v) Free a vector.
vec_index(b, vec) Find first set bit starting from b in vector v. If no bit is found, return vec_numbits(v).
vec_init() Initialize package.
vec_or(v1, v2, v3) Compute v1 = v2 | v3.
vec_orass(v1, v2) Compute v1 |= v2.
vec_println(v) Write out vector.
vec_realloc(v, numbits) Realloc a vector to have numbits bits in it. Extra bits are set to 0.
vec_set(v) Set vector.
vec_setbit(b, v) Set bit b in vector v.
vec_sub(v1, v2, v3) Compute v1 = v2 - v3.
vec_subass(v1, v2) Compute v1 -= v2.
vec_term() Terminate package.
vec_testbit(b, v) Test bit b in vector v.
vec_xor(v1, v2, v3) Compute v1 = v2 ^ v3.
vec_xorass(v1, v2) Compute v1 ^= v2.
