Also, change sources.redhat.com to sourceware.org.
This patch was automatically generated by running the following shell
script, which uses GNU sed, and which avoids modifying files imported
from upstream:
sed -ri '
s,(http|ftp)(://(.*\.)?(gnu|fsf|sourceware)\.org($|[^.]|\.[^a-z])),https\2,g
s,(http|ftp)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g
' \
$(find $(git ls-files) -prune -type f \
! -name '*.po' \
! -name 'ChangeLog*' \
! -path COPYING ! -path COPYING.LIB \
! -path manual/fdl-1.3.texi ! -path manual/lgpl-2.1.texi \

! '(' -name configure \
-execdir test -f configure.ac -o -f configure.in ';' ')' \
! '(' -name preconfigure \
-execdir test -f preconfigure.ac ';' ')' \
-print)
and then by running 'make dist-prepare' to regenerate files built
from the altered files, and then executing the following to cleanup:
chmod a+x sysdeps/unix/sysv/linux/riscv/configure
# Omit irrelevant whitespace and comment-only changes,
# perhaps from a slightly-different Autoconf version.
git checkout -f \
sysdeps/csky/configure \
sysdeps/hppa/configure \
sysdeps/riscv/configure \
sysdeps/unix/sysv/linux/csky/configure
# Omit changes that caused a pre-commit check to fail like this:
# remote: *** error: sysdeps/powerpc/powerpc64/ppc-mcount.S: trailing lines
git checkout -f \
sysdeps/powerpc/powerpc64/ppc-mcount.S \
sysdeps/unix/sysv/linux/s390/s390-64/syscall.S
# Omit change that caused a pre-commit check to fail like this:

git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

/* INTERNAL_SIZE_T is the word-size used for internal bookkeeping of
|
|
chunk sizes.
|
|
|
|
The default version is the same as size_t.
|
|
|
|
While not strictly necessary, it is best to define this as an
|
|
unsigned type, even if size_t is a signed type. This may avoid some
|
|
artificial size limitations on some systems.
|
|
|
|
On a 64-bit machine, you may be able to reduce malloc overhead by
|
|
defining INTERNAL_SIZE_T to be a 32 bit `unsigned int' at the
|
|
expense of not being able to handle more than 2^32 of malloced
|
|
space. If this limitation is acceptable, you are encouraged to set
|
|
this unless you are on a platform requiring 16byte alignments. In
|
|
this case the alignment requirements turn out to negate any
|
|
potential advantages of decreasing size_t word size.
|
|
|
|
Implementors: Beware of the possible combinations of:
|
|
- INTERNAL_SIZE_T might be signed or unsigned, might be 32 or 64 bits,
|
|
and might be the same width as int or as long
|
|
- size_t might have different width and signedness as INTERNAL_SIZE_T
|
|
- int and long might be 32 or 64 bits, and might be the same width
|
|
|
|
To deal with this, most comparisons and difference computations
|
|
among INTERNAL_SIZE_Ts should cast them to unsigned long, being
|
|
aware of the fact that casting an unsigned int to a wider long does
|
|
not sign-extend. (This also makes checking for negative numbers
|
|
awkward.) Some of these casts result in harmless compiler warnings
|
|
on some systems. */
