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.
The cgen code uses DI as int64_t and UDI as uint64_t. The DI macros
are used to construct 64-bit values from 32-bit values (for the low
and high parts). The MAKEDI macro casts the high 32-bit value to a
signed 32-bit value before shifting. If this created a negative
value, this would be undefined behavior according to the C standard.
All we care about is shifting the 32-bits as they are to the high
32-bits, not caring about sign extension (since there's nothing left
to shift into), and the low 32-bits being empty. This is what we
get from shifting an unsigned value, so cast it to unsigned 32-bit
to avoid undefined behavior.
While we're here, change the SETLODI macro to truncate the lower
value to 32-bits before we set it. If it was passing in a 64-bit
value, those high bits would get included too, and that's not what
we want.
Similarly, tweak the SETHIDI macro to cast the value to an unsigned
64-bit instead of a signed 64-bit. If the value was only 32-bits,
the behavior would be the same. If it happened to be signed 64-bit,
it would trigger the undefined behavior too.
This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.
The cgen framework provides a "VOID" type for code to use, but this
defines ends up conflicting with the standard Windows VOID define.
Since they actually define to the same thing ("void"), undef it here
to fix the Windows build.
We might want to reconsider the need for "VOID" in cgen, but that
will take larger discussion & coordination with the cgen project.
This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...
gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Rather than include this for some targets, set it up so we can build it
all the time via the common code. This makes it easier for targets to
opt into it when they're ready, increases build coverage, and allows us
to centralize much of the logic.
We also get to delete tconfig.h from two more targets -- they were
setting WITH_DEVICES to 0 which has the same behavior as not defining
it at all.
While the SIM_HAVE_MODEL knob is gone, we now have WITH_MODEL_P, but it
is only used by the common sim-model code. We use it to declare dummy
model lists when the arch hasn't created its own.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
