This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

/* 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.
