@ -19,39 +19,39 @@ Major new features:
* On Linux, the pthread_gettid_np function has been added.
* The ISO C2Y family of unsigned abs functions, i.e.
uabs, ulabs, ullabs and uimaxabs, are now supported.
* The ISO C2Y family of unsigned abs functions, i.e. uabs, ulabs,
ullabs, and uimaxabs, is now supported.
* On Linux, the <termios.h> interface now supports arbitrary baud rates;
speed_t is redefined to simply be the baud rate specified as an
unsigned int, which matches the kernel interface.
* The thread-local cache in malloc (tcache) now supports caching of large
blocks. This feature can be enabled by setting the tunable
glibc.malloc.tcache_max to a larger value (max 4194304).
Tcache is also significantly faster for small sizes.

large blocks. This feature can be enabled by setting the tunable
glibc.malloc.tcache_max to a larger value (max 4194304). Tcache is
also significantly faster for small sizes.
* A new configure option, "--eanble-sframe", can be used to enable
the SFrame support on the GNU C Libraries. The SFrame is a new
stack trace information which can be used by backtrace. It requires
binutils with minimum version of 2.45.
* A new configure option, "--enable-sframe", can be used to enable
SFrame support of the GNU C Libraries. SFrame is a new stack trace
information format which can be used by backtrace. It requires
binutils with a minimum version of 2.45.
Deprecated and removed features, and other changes affecting compatibility:
* The glibc.rtld.execstack now supports a compatibility mode to allow
programs that require an executable stack through dynamic loaded
shared libraries.
* The glibc.rtld.execstack tunable now supports a compatibility mode to
allow programs that require an executable stack through dynamically
loaded shared libraries.
* On Linux, the <termio.h> header and the definition of struct termio
in <sys/ioctl.h> have been removed. The termio interface has been
obsolete since the very first version of POSIX.1 in 1988, replaced
with <termios.h>.
* The support for TX lock elision of pthread mutexes is deprecated on
all architectures and will be removed in the next release.
* The support for TX lock elision of pthread mutexes has been deprecated
on all architectures and will be removed in the next release.
* On AArch64 Linux targets supporting SME, setjmp and sigsetjmp will
disable ZA state of SME.
* On AArch64 Linux targets supporting the Scalable Matrix Extension
(SME), setjmp and sigsetjmp will disable the ZA state of SME.
