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)(://(.*\.)?)sources\.redhat\.com($|[^.]|\.[^a-z]),https\2sourceware.org\4,g

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

/* Normally, this uses

|
|
|
((xword - 0x0101010101010101) & 0x8080808080808080) test
|
|
|
|
to find out if any byte in xword could be zero. This is fast, but
|
|
|
|
also gives false alarm for any byte in range 0x81-0xff. It does
|
|
|
|
not matter for correctness, as if this test tells us there could
|
|
|
|
be some zero byte, we check it byte by byte, but if bytes with
|
|
|
|
high bits set are common in the strings, then this will give poor
|
|
|
|
performance. You can #define EIGHTBIT_NOT_RARE and the algorithm
|
|
|
|
will use one tick slower, but more precise test
|
|
|
|
((xword - 0x0101010101010101) & (~xword) & 0x8080808080808080),
|
|
|
|
which does not give any false alarms (but if some bits are set,
|
|
|
|
one cannot assume from it which bytes are zero and which are not).
|
|
|
|
It is yet to be measured, what is the correct default for glibc
|
|
|
|
in these days for an average user.
