4Subject: [PATCH] mips-linux-nat: Define _ABIO32 if not defined
5
6This helps building gdb on mips64 on musl, since
7musl does not provide sgidefs.h this define is
8only defined when GCC is using o32 ABI, in that
9case gcc emits it as built-in define and hence
10it works ok for mips32

100+/* Recognizing signal handler frames. */
101+
102+/* GNU/Linux has two flavors of signals. Normal signal handlers, and
103+ "realtime" (RT) signals. The RT signals can provide additional
104+ information to the signal handler if the SA_SIGINFO flag is set
105+ when establishing a signal handler using `sigaction'. It is not
106+ unlikely that future versions of GNU/Linux will support SA_SIGINFO
107+ for normal signals too. */
108+
109+/* When the SH Linux kernel calls a signal handler and the
110+ SA_RESTORER flag isn't set, the return address points to a bit of
111+ code on the stack. This function returns whether the PC appears to
112+ be within this bit of code.
113+
114+ The instruction sequence for normal signals is
115+ mov.w 1f,r3
116+ trapa #16
117+ or r0, r0
118+ or r0, r0
119+ or r0, r0
120+ or r0, r0
121+ or r0, r0
122+ 1: .word __NR_sigreturn
123+ or 0x9305 0xc310 0x200b 0x200b 0x200b 0x200b 0x200b 0x0077.
124+
125+ Checking for the code sequence should be somewhat reliable, because
126+ the effect is to call the system call sigreturn. This is unlikely
127+ to occur anywhere other than a signal trampoline.
128+
129+ It kind of sucks that we have to read memory from the process in
130+ order to identify a signal trampoline, but there doesn't seem to be
131+ any other way. The PC_IN_SIGTRAMP macro in tm-linux.h arranges to
132+ only call us if no function name could be identified, which should
133+ be the case since the code is on the stack.
134+
135+ Detection of signal trampolines for handlers that set the
136+ SA_RESTORER flag is in general not possible. Unfortunately this is
137+ what the GNU C Library has been doing for quite some time now.
138+ However, as of version 2.1.2, the GNU C Library uses signal
139+ trampolines (named __restore and __restore_rt) that are identical
140+ to the ones used by the kernel. Therefore, these trampolines are
141+ supported too. */

4Subject: [PATCH] Dont disable libreadline.a when using --disable-static
5
6If gdb is configured with --disable-static then this is dutifully passed to
7readline which then disables libreadline.a, which causes a problem when gdb
8tries to link against that.
9
10To ensure that readline always builds static libraries, pass --enable-static to
11the sub-configure.

5
6Build fix for MIPS with musl libc
7
8The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
9but not by musl. Regardless of the libc, the kernel headers provide
10<asm/sgidefs.h> which provides the same definitions, so use that
11instead.

6GCC detects that we call 'restrict' as param name in function
7signatures and complains since both params are called 'restrict'
8therefore we use __restrict to denote the C99 keywork

11 The pthread_sigmask() and sigprocmask() functions shall fail if:
12
13 [EINVAL]
14 The value of the how argument is not equal to one of the defined values.
15
16and this is how musl-libc is currently doing. Fix the call to be safe
17and correct

4Subject: [PATCH] gdbserver ctrl-c handling
5
6This problem was created by the upstream commit 78708b7c8c
7After applying the commit, it will send SIGINT to the process
8group(-signal_pid).
9But if we use gdbserver send SIGINT, and the attached process is not a
10process
11group leader, then the "kill (-signal_pid, SIGINT)" returns error and
12fails to
13interrupt the attached process.
