#ifndef SIM_BITS_H
#define SIM_BITS_H
/* Bit manipulation routines:
Bit numbering: The bits are numbered according to the target ISA's
convention. That being controlled by WITH_TARGET_WORD_MSB. For
the PowerPC (WITH_TARGET_WORD_MSB == 0) the numbering is 0..31
while for the MIPS (WITH_TARGET_WORD_MSB == 31) it is 31..0.
Size convention: Each macro is in three forms - <MACRO>32 which
operates in 32bit quantity (bits are numbered 0..31); <MACRO>64
which operates using 64bit quantites (and bits are numbered 0..63);
and <MACRO> which operates using the bit size of the target
architecture (bits are still numbered 0..63), with 32bit
architectures ignoring the first 32bits leaving bit 32 as the most
significant.
NB: Use EXTRACTED, MSEXTRACTED and LSEXTRACTED as a guideline for
naming. LSMASK and LSMASKED are wrong.
BIT*(POS): `*' bit constant with just 1 bit set.
LSBIT*(OFFSET): `*' bit constant with just 1 bit set - LS bit is
zero.
MSBIT*(OFFSET): `*' bit constant with just 1 bit set - MS bit is
zero.
MASK*(FIRST, LAST): `*' bit constant with bits [FIRST .. LAST]
set. The <MACRO> (no size) version permits FIRST >= LAST and
generates a wrapped bit mask vis ([0..LAST] | [FIRST..LSB]).
LSMASK*(FIRST, LAST): Like MASK - LS bit is zero.
MSMASK*(FIRST, LAST): Like MASK - LS bit is zero.
MASKED*(VALUE, FIRST, LAST): Masks out all but bits [FIRST
.. LAST].
LSMASKED*(VALUE, FIRST, LAST): Like MASKED - LS bit is zero.
MSMASKED*(VALUE, FIRST, LAST): Like MASKED - MS bit is zero.
EXTRACTED*(VALUE, FIRST, LAST): Masks out bits [FIRST .. LAST] but
also right shifts the masked value so that bit LAST becomes the
least significant (right most).
LSEXTRACTED*(VALUE, FIRST, LAST): Same as extracted - LS bit is
zero.
MSEXTRACTED*(VALUE, FIRST, LAST): Same as extracted - MS bit is
zero.
SHUFFLED**(VALUE, OLD, NEW): Mask then move a single bit from OLD
new NEW.
MOVED**(VALUE, OLD_FIRST, OLD_LAST, NEW_FIRST, NEW_LAST): Moves
things around so that bits OLD_FIRST..OLD_LAST are masked then
moved to NEW_FIRST..NEW_LAST.
INSERTED*(VALUE, FIRST, LAST): Takes VALUE and `inserts' the (LAST
- FIRST + 1) least significant bits into bit positions [ FIRST
.. LAST ]. This is almost the complement to EXTRACTED.
IEA_MASKED(SHOULD_MASK, ADDR): Convert the address to the targets
natural size. If in 32bit mode, discard the high 32bits.
EXTEND*(VALUE): Convert the `*' bit value to the targets natural
word size. Sign extend the value if needed.
align_*(VALUE, BYTES): Round the value so that it is aligned to a
BYTES boundary.
ROT*(VALUE, NR_BITS): Return the `*' bit VALUE rotated by NR_BITS
right (positive) or left (negative).
ROTL*(VALUE, NR_BITS): Return the `*' bit value rotated by NR_BITS
left. 0 <= NR_BITS <= `*'.
ROTR*(VALUE, NR_BITS): Return the `*' bit value rotated by NR_BITS
right. 0 <= NR_BITS <= N.
SEXT*(VALUE, SIGN_BIT): Treat SIGN_BIT as VALUEs sign, extend it ti
`*' bits.
Note: Only the BIT* and MASK* macros return a constant that can be
used in variable declarations.
