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 \ ! -path manual/texinfo.tex ! -path scripts/config.guess \ ! -path scripts/config.sub ! -path scripts/install-sh \ ! -path scripts/mkinstalldirs ! -path scripts/move-if-change \ ! -path INSTALL ! -path locale/programs/charmap-kw.h \ ! -path po/libc.pot ! -path sysdeps/gnu/errlist.c \ ! '(' -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: # remote: *** error: sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S: last line does not end in newline git checkout -f sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S

/* An architecture-specific version of this file has to defined a
|
|
number of symbols:
|
|
|
|
TLS_TCB_AT_TP or TLS_DTV_AT_TP
|
|
|
|
The presence of one of these symbols signals which variant of
|
|
the TLS ABI is used. There are in the moment two variants
|
|
available:
|
|
|
|
* the thread pointer points to a thread control block
|
|
|
|
* the thread pointer points to the dynamic thread vector
|
|
|
|
|
|
TLS_TCB_SIZE
|
|
|
|
This is the size of the thread control block structure. How
|
|
this is actually defined depends on the ABI. The thread control
|
|
block could be internal descriptor of the thread library or
|
|
just a data structure which allows finding the DTV.
|
|
|
|
TLS_INIT_TCB_SIZE
|
|
|
|
Similarly, but this value is only used at startup and in the
|
|
dynamic linker itself. There are no threads in use at that time.
|
|
|
|
|
|
TLS_TCB_ALIGN
|
|
|
|
Alignment requirements for the TCB structure.
|
|
|
|
TLS_INIT_TCB_ALIGN
|
|
|
|
Similarly, but for the structure used at startup time.
|
|
|
|
|
|
INSTALL_DTV(tcb, init_dtv)
|
|
|
|
This macro must install the given initial DTV into the thread control
|
|
block TCB. The normal runtime functionality must then be able to
|
|
use the value.
|
|
|
|
|
|
TLS_INIT_TP(tcb)
|
|
|
|
This macro must initialize the thread pointer to enable normal TLS
|
|
operation. The parameter is a pointer to the thread control block.
|
|
ld.so calls this macro once.
|
|
|
|
|
|
THREAD_DTV()
|
|
|
|
This macro returns the address of the DTV of the current thread.
|
|
This normally is done using the thread register which points
|
|
to the dtv or the TCB (from which the DTV can found).
|
|
|
|
|
|
THREAD_GSCOPE_IN_TCB
|
|
|
|
This should be set to 1 if the global scope flag is stored within the TCB.
|
|
When set to 0, GL(_dl_thread_gscope_count) will be defined to store it.
