-
-This helps building gdb on mips64 on musl, since
-musl does not provide sgidefs.h this define is
-only defined when GCC is using o32 ABI, in that
-case gcc emits it as built-in define and hence
-it works ok for mips32

-+   information to the signal handler if the SA_SIGINFO flag is set
-+   when establishing a signal handler using `sigaction'.  It is not

-+   SA_RESTORER flag isn't set, the return address points to a bit of
-+   code on the stack.  This function returns whether the PC appears to
-+   be within this bit of code.
-+
-+   The instruction sequence for normal signals is

-+
-+   Checking for the code sequence should be somewhat reliable, because
-+   the effect is to call the system call sigreturn.  This is unlikely
-+   to occur anywhere other than a signal trampoline.
-+
-+   It kind of sucks that we have to read memory from the process in
-+   order to identify a signal trampoline, but there doesn't seem to be
-+   any other way.  The PC_IN_SIGTRAMP macro in tm-linux.h arranges to
-+   only call us if no function name could be identified, which should
-+   be the case since the code is on the stack.
-+
-+   Detection of signal trampolines for handlers that set the
-+   SA_RESTORER flag is in general not possible.  Unfortunately this is
-+   what the GNU C Library has been doing for quite some time now.
-+   However, as of version 2.1.2, the GNU C Library uses signal
-+   trampolines (named __restore and __restore_rt) that are identical
-+   to the ones used by the kernel.  Therefore, these trampolines are
-+   supported too.  */

-Subject: [PATCH 06/10] Dont disable libreadline.a when using --disable-static
-
-If gdb is configured with --disable-static then this is dutifully passed to
-readline which then disables libreadline.a, which causes a problem when gdb
-tries to link against that.
-
-To ensure that readline always builds static libraries, pass --enable-static to
-the sub-configure.

-gdb: Backport patch to support changes with AVX and MPX
-
-The current MPX target descriptions assume that MPX is always combined
-with AVX, however that's not correct.  We can have machines with MPX
-and without AVX; or machines with AVX and without MPX.
-
-This patch adds new target descriptions for machines that support
-both MPX and AVX, as duplicates of the existing MPX descriptions.
-
-The following commit will remove AVX from the MPX-only descriptions.
-
-Upstream-Status: Backport
