In mi_interpreter_init, multiple MI consoles/channels are created and a quoting
character is given. In mi_console_raw_packet, we check if the value is not 0
to decide if we should quote the string, but we don't use the value. It is
hardcoded to ". We might never use another quoting character than an actual
quote, but I suggest we change it, for correctness. There is not visible
behavior change.
I changed the latest fputs_unfiltered changed to fputc_unfiltered just to stay
consistent.

I think "set debugvarobj" has the wrong name.
It ought to be "set debug varobj", like gdb's other debug settings.
This patch makes the change.
I chose not to install deprecated aliases, since this is only a debug
setting; but if someone feels strongly about it I will add them.
Built and regtested on x86-64 Fedora 20.

This fixes an issue with Mark Shinwell's "Rearrange MIPS INSN* masks" patch
(https://sourceware.org/ml/binutils/2007-11/msg00231.html). In the patch
the pref instruction had its membership flags changed from I4|I32|G3 to
I4_32|G3. Unfortunately G3 was defined as being I4, which made the actual
expanded flags as: I4|I32|I4 and therefore the membership flags should have
been I4_32. Since the patch was committed G3 was redefined to be I4|EE. This
fix just removes I4 from G3 making the expanded membership flags for pref as
I4_32|EE.
ChangeLog:
opcodes/
* mips-opc.c (G3): Remove I4.
Hi,
I recently see the fail in dwzbuildid.exp below on some targets,
(gdb) print the_int
No symbol "the_int" in current context.
(gdb) FAIL: gdb.dwarf2/dwzbuildid.exp: mismatch: print the_int
Looks the pattern expects to see "No symbol table is loaded", which
is emitted in c-exp.y,
variable: name_not_typename
....
if (msymbol.minsym != NULL)
write_exp_msymbol (pstate, msymbol);
else if (!have_full_symbols () && !have_partial_symbols ())
error (_("No symbol table is loaded. Use the \"file\" command."));
else
error (_("No symbol \"%s\" in current context."),
copy_name ($1.stoken));
it is expected to have no full symbols nor partial symbols, but something
brings full symbols or partial symbols in. I added "maint info symtabs"
and "maint info psymtabs" in dwzbuildid.exp, and it shows symbols are from
ld.so, which has debug information. Then, I reproduce the fail like this,
$ make check RUNTESTFLAGS="CFLAGS_FOR_TARGET='-Wl,-rpath=${glibc_build}:${glibc_build}/math -Wl,--dynamic-linker=${glibc_build}/elf/ld.so' dwzbuildid.exp"
${glibc_build} is the glibc build tree. Debug information is not striped,
so the test fail. However, if I strip debug information from libc.so, libm.so
and ld.so. The test passes.
This patch is to relax the pattern to match the both cases that glibc build
has and has not debug information.

This patch updates multiple opcode prefix processing:
1. Always print prefix together with bad opcode.
2. Since the last seen segment register prefix is active, we only print
the active segment register in the memory operand.
3. The 0xf2 and 0xf3 prefixes take precedence over the 0x66 prefix as the
opcode prefix. Also the last of the 0xf2 and 0xf3 prefixes wins.
4. Ignore invalid 0xf2/0xf3 prefixes if they aren't mandatory.

In gdb.trace/unavailable.exp, an action is defined to collect
struct_b.struct_a.array[2] and struct_b.struct_a.array[100],
struct StructB
{
int d, ef;
StructA struct_a;
int s:1;
static StructA static_struct_a;
const char *string;
};
and the other files are not collected.
When GDB examine traceframe collected by the action, "struct_b" is
unavailable completely, which is wrong.
(gdb) p struct_b
$1 = <unavailable>
When GDB reads 'struct_b', it will request to read memory at struct_b's address
of length LEN. Since struct_b.d is not collected, no 'M' block
includes the first part of the desired range, so tfile_xfer_partial returns
TARGET_XFER_UNAVAILABLE and GDB thinks the whole requested range is unavailable.
In order to fix this problem, in the iteration to 'M' blocks, we record the
lowest address of blocks within the request range. If it has, the requested
range isn't unavailable completely. This applies to ctf too. With this patch
applied, the result looks good and fails in unavailable.exp is fixed.
(gdb) p struct_b
$1 = {d = <unavailable>, ef = <unavailable>, struct_a = {a = <unavailable>, b = <unavailable>, array = {<unavailable>,
