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 ';' ')' \

-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 \

In the thread-specific locale model (see `uselocale' in <locale.h>)
|
|
we cannot use global variables for these as was done in the past.
|
|
Instead, the following accessor functions return the address of
|
|
each variable, which is local to the current thread if multithreaded.
|
|
|
|
These point into arrays of 384, so they can be indexed by any `unsigned
|
|
char' value [0,255]; by EOF (-1); or by any `signed char' value
|
|
[-128,-1). ISO C requires that the ctype functions work for `unsigned
|
|
char' values and for EOF; we also support negative `signed char' values
|
|
for broken old programs. The case conversion arrays are of `int's
|
|
rather than `unsigned char's because tolower (EOF) must be EOF, which
|
|
doesn't fit into an `unsigned char'. But today more important is that
|
|
the arrays are also used for multi-byte character sets. */
