@ -4165,6 +4165,29 @@ There are patches for Solaris 8 (117350-12 or newer for SPARC,
117351-12 or newer for Intel) and Solaris 9 (117171-11 or newer for
SPARC, 117172-11 or newer for Intel) that address this problem.
Solaris~8 provides an alternate implementation of the thread libraries,
@samp{libpthread} and @samp{libthread}. They are required for TLS
support and have been made the default in Solaris~9, so they are always
used on Solaris~8.
Thread-local storage (TLS) is supported in Solaris~8 and 9, but requires
some patches. The @samp{libthread} patches provide the
@code{__tls_get_addr} (SPARC, 64-bit x86) resp.@ @code{___tls_get_addr}
(32-bit x86) functions. On Solaris~8, you need 108993-26 or newer on
SPARC, 108994-26 or newer on Intel. On Solaris~9, the necessary support
on SPARC is present since FCS, while 114432-05 or newer is reqired on
Intel. Additionally, on Solaris~8, patch 109147-14 or newer on SPARC or
109148-22 or newer on Intel are required for the Sun @command{ld} and
runtime linker (@command{ld.so.1}) support. Again, Solaris~9/SPARC
works since FCS, while 113986-02 is required on Intel. The linker
patches must be installed even if GNU @command{ld} is used. Sun
@command{as} in Solaris~8 and 9 doesn't support the necessary
relocations, so GNU @command{as} must be used. The @command{configure}
script checks for those prerequisites and automatically enables TLS
support if they are met. Although those minimal patch versions should
work, it is recommended to use the latest patch versions which include
additional bug fixes.

@item arm_neon_fp16
NEON and half-precision floating point support. Only ARM targets
support this feature, and only then in certain modes; see
the @ref{arm_neon_ok,,arm_neon_fp16_ok effective target keyword}.
@item tls
Add the target-specific flags needed to use thread-local storage.
