The v5.4 branch won't get any translation updates so the fuzzy
strings and obsolete strings are all useless. Cleaning them up
makes the files smaller.
./update-po
for I in *.po
do
msgattrib --clear-fuzzy --clear-previous --empty \
--no-obsolete --no-wrap "$I" > tmp
mv tmp "$I"
done
The po4a run gave "Parse error at" message from fr.po but
after the fr.po was rewritten the error is gone.
The .po files from the Translation Project come with unwrapped
strings so this matches it.
This may reduce the noise in diffs too. When the beginning of
a paragraph had changed, the rest of the lines got rewrapped
in msgsid. Now it's just one very long line that changes when
a paragraph has been edited.
The --add-location=file option was removed as redundant. The line
numbers don't exist in the .pot file due to --porefs file and thus
they cannot get copied to the .po files either.

It is logical why it cannot know for sure that the value has
to be at most 4 if it is less than 16.
The x86 filter is based on a very old LZMA SDK version. Newer
ones have quite a different implementation for the same filter.
Thanks to Sam James.

Clang 17 with -fsanitize=address,undefined:
src/liblzma/common/filter_common.c:366:8: runtime error:
call to function encoder_find through pointer to incorrect
function type 'const lzma_filter_coder *(*)(unsigned long)'
src/liblzma/common/filter_encoder.c:187: note:
encoder_find defined here
Use a wrapper function to get the correct type neatly.
This reduces the number of casts needed too.
This issue could be a problem with control flow integrity (CFI)
methods that check the function type on indirect function calls.

It's undefined behavior. The result wasn't ever used as it occurred
in the last iteration of a loop.

On LZMA_DATA_ERROR from lzma_index_buffer_decode(), *i = NULL was
already done but this adds a test for that case too.
(cherry picked from commit 575b11b0d2)
liblzma guarantees that the product of the allocation size arguments
will fit in size_t.
Putting the pre-increment in the if-statement was clearly wrong
although in practice it didn't matter here as the function is
called only a couple of times.
(cherry picked from commit 7f865577a6)
If the arguments to lzma_index_decoder() or lzma_index_buffer_decode()
were such that LZMA_PROG_ERROR was returned, the lzma_index **i
argument wasn't touched even though the API docs say that *i = NULL
is done if an error occurs. This obviously won't be done even now
if i == NULL but otherwise it is best to do it due to the wording
in the API docs.
In practice this matters very little: The problem can occur only
if the functions are called with invalid arguments, that is,
the calling application must already have a bug.
(cherry picked from commit 71eed2520e)
The API docs clearly say that if error_pos isn't NULL then *error
is always set on any error. However, it wasn't touched if str == NULL
or filters == NULL or unsupported flags were specified.

This does the previous commit with CMake.
AC_EGREP_CPP uses AC_REQUIRE so the outermost if-commands must
be changed to AS_IF to ensure that things wont break some day.

It doesn't support the __symver__ attribute or __asm__(".symver ...").
The generic symbol versioning can still be used since it only needs
linker support.
(cherry picked from commit c273123ed0)
NVHPC compiler has several issues that make it impossible to
build liblzma:
- the compiler cannot handle unions that contain pointers that
are not the first members;
- the compiler fails to produce valid code for delta_decode if the
vectorization is enabled, which results in failed tests.
This introduces NVHPC-specific workarounds that address the issues.

(cherry picked from commit 096bc0e3f8)
There are cases when the users want to decide themselves whether
they want to have the generic (even on GNU/Linux) or the linux
(even if we do not recommend that) symbol versioning variant.
The former might be needed to circumvent compiler issues (i.e.
the compiler does not support all features that are required
for the linux versioning), the latter might help in overriding
the assumptions made in the configure script.
