bit.ops

NAME

bit.ops - Bitwise Operations

DESCRIPTION

Operations that deal with bits directly, either individually or in groups.

The variant with an appended s like bands work on strings.

The variants with a prepended n_ like <n_bnot> generate a new target PMC. If possible, they use the appropriate language type, specified with .HLL.

band(inout INT, in INT): Set the bits of $1 according to the and of the corresponding bits from $1 and $2.
band(out INT, in INT, in INT): Set the bits of $1 according to the and of the corresponding bits from $2 and $3.
bands(inout STR, in STR): Set the bits of $1 according to the and of the corresponding bits from $1 and $2.
bands(out STR, in STR, in STR): Set the bits of $1 according to the and of the corresponding bits from $2 and $3.
bnot(inout INT)
bnot(invar PMC): Sets $1 to bitwise not $1 inplace.
bnot(out INT, in INT)
bnot(out PMC, invar PMC)
n_bnot(out PMC, invar PMC): Set the bits of $1 to the not of the corresponding bits from $2.
bnots(inout STR)
bnots(invar PMC)
bnots(out STR, in STR)
bnots(out PMC, invar PMC)
n_bnots(out PMC, invar PMC): Set the bits of $1 to the not of the corresponding bits from $2.
bor(inout INT, in INT): Set the bits of $1 according to the or of the corresponding bits from $1 and $2.
bor(out INT, in INT, in INT): Set the bits of $1 according to the or of the corresponding bits from $2 and $3.
bors(inout STR, in STR): Set the bits of $1 according to the or of the corresponding bits from $1 and $2.
bors(out STR, in STR, in STR): Set the bits of $1 according to the or of the corresponding bits from $2 and $3.
shl(inout INT, in INT): Shift left $1 by $2 bits.
shl(out INT, in INT, in INT): Set $1 to the value of $2 shifted left by $3 bits.
shr(inout INT, in INT): Shift right $1 by $2 bits.
shr(out INT, in INT, in INT): Set $1 to the value of $2 shifted right by $3 bits.
lsr(out INT, in INT): Shift $1 logically shifted right by $2 bits.
lsr(out INT, in INT, in INT): Set $1 to the value of $2 logically shifted right by $3 bits.
rot(out INT, in INT, in INT, inconst INT): Rotate $2 left or right by $3 and place result in $1. $4 is the amount of bits to rotate, 32 bit on a 32-bit CPU and 32 or 64 on a 64-bit CPU. If the rotate count is negative a rotate right by ($3+$4) is performed.
bxor(inout INT, in INT): Set the bits of $1 according to the xor of the corresponding bits from $1 and $2.
bxor(out INT, in INT, in INT): Set the bits of $1 according to the xor of the corresponding bits from $2 and $3.
bxors(inout STR, in STR): Set the bits of $1 according to the xor of the corresponding bits from $1 and $2.
bxors(out STR, in STR, in STR): Set the bits of $1 according to the xor of the corresponding bits from $2 and $3.
