+Subject: [PATCH] [gdb/cli] Don't emit emojis in MI
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+PR mi/34501 reports the following:
+...
+$ gdb -q \
+    -ex 'set charset UTF-8' \
+    -ex 'interpreter-exec mi2 "-break-insert -f foo' \
+    -ex quit
+&"�\235\214�\217 No symbol table is loaded.  Use the \"file\" command.\n"
+  ...
+$
+...
+
+The output is a bit odd, but that gets better if we use
+'set print sevenbit-strings on':
+...
+&"\342\235\214\357\270\217 No symbol table is loaded.  Use the \"file\" command.\n"
+...
+
+The output we see there is the error emoji:
+...
+$ gdb
+(gdb) b foo
+❌️ No symbol table is loaded.  Use the "file" command.
+...
+
+More specifically, two utf-8 encoded unicode characters:
+- Cross Mark [1]: 0xE2 0x9D 0x8C
+- Variation Selector-16 (VS16) [2]: 0xEF 0xB8 0x8F
+
+Now the question: is GDB doing something wrong?
+
+I think we probably should encode unicode characters in MI error strings as
+octal escapes, independent of the sevenbit-strings setting.  This patch does
+not address this part.
+
+Then there's the question whether we should emit emojis in MI error strings in
+the first place [3].  In principle they're unicode characters encoded in UTF-8,
+and we can expect other such unicode characters in translated error strings.
+
+But, given that MI has can_emit_style_escape () == false, and already filters
+out ANSI escape sequences, I think it's reasonable to also disable emojis.
+
+As for implementation, I introduced a function emoji_allowed alongside
+can_emit_style_escape, which defaults to the value of can_emit_style_escape.
+
+Tested on x86_64-linux.

+Subject: [PATCH] gdb/ser-unix: work around conflicting types for tcflag_t
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf8
+Content-Transfer-Encoding: 8bit
+
+When trying to cross-compile GDB to sparc-buildroot-linux-uclibc, I get:
+
+      CXX    ser-unix.o
+    In file included from /data1/smarchi/many-buildroots/toolchains/sparc/sparc-buildroot-linux-uclibc/sysroot/usr/include/termios.h:39,
+                     from /home/smarchi/src/binutils-gdb/gdb/ser-unix.c:51:
+    /data1/smarchi/many-buildroots/toolchains/sparc/sparc-buildroot-linux-uclibc/sysroot/usr/include/bits/termios.h:26:22: error: conflicting declaration ‘typedef unsigned int tcflag_t’
+       26 | typedef unsigned int tcflag_t;
+          |                      ^~~~~~~~
+    In file included from /home/smarchi/src/binutils-gdb/gdb/ser-unix.c:46:
+    /data1/smarchi/many-buildroots/toolchains/sparc/sparc-buildroot-linux-uclibc/sysroot/usr/include/asm/termbits.h:13:25: note: previous declaration as ‘typedef long unsigned int tcflag_t’
+       13 | typedef unsigned long   tcflag_t;
+          |                         ^~~~~~~~
+
+uClibc and the kernel don't agree on the definition of tcflag_t for this
+architecture.  Here' uClibc [1]:
+
+    typedef unsigned int tcflag_t;
+
+And here's the kernel [2]:
+
+    #if defined(__sparc__) && defined(__arch64__)
+    typedef unsigned int	tcflag_t;
+    #else
+    typedef unsigned long	tcflag_t; <--- that branch is take
+    #endif
+
+glibc [3] has the same definition as uClibc, so we would get the same
+problem.
+
+I propose to work around this the same way as we handle differences in
+the termios structure, by renaming the version from the kernel.
+
+I opened a bug on the glibc bugzilla [4] to ask if this is something
+that would need to be fixed on the libc side, but in the mean time we
+need to work around it.
