Add support for displaying structures and bitfields for registers when
executing "maint print c-tdesc". This command is also used when
converting the xml target description file into c file.
Example of the behaviour is given below reporting a snipet of the xml file
and a snippet of the c code generated.
XML file contains:
...
<union id="vecint">
<field name="v4" type="v4int8"/>
<field name="v2" type="v2int16"/>
</union>
<struct id="struct1">
<field name="v4" type="v4int8"/>
<field name="v2" type="v2int16"/>
</struct>
<struct id="struct2" size="8">
<field name="f1" start="0" end="34"/>
<field name="f2" start="63" end="63"/>
</struct>
...
Setting this xml file as target description file and
issuing the maintenance print c-tdesc the following output
is obtained:
feature = tdesc_create_feature (result, "extra");
field_type = tdesc_named_type (feature, "int8");
tdesc_create_vector (feature, "v4int8", field_type, 4);
field_type = tdesc_named_type (feature, "int16");
tdesc_create_vector (feature, "v2int16", field_type, 2);
type = tdesc_create_union (feature, "vecint");
field_type = tdesc_named_type (feature, "v4int8");
tdesc_add_field (type, "v4", field_type);
field_type = tdesc_named_type (feature, "v2int16");
tdesc_add_field (type, "v2", field_type);
C output is not supported type "struct1".
This is finally the issue.

This fixes a couple of compiler warnings in rw_common when calling
target_read_memory/target_write_memory due to the type of parameter
"buf" (char *) not matching what these function expect (gdb_byte *).
gdb/ChangeLog:
* sol-thread.c (rw_common): Change type of parameter "buf"
to "gdb_byte *".
(ps_pdwrite, ps_ptwrite): Cast parameter "buf" in call to
rw_common to "gdb_byte *" instead of "char *".
gdb/ChangeLog:
* sol-thread.c (info_cb) [ti.ti_startfunc != 0]: Change type
of local variable msym to const struct bound_minimal_symbol.
Adjust use accordingly.
[ti.ti_state == TD_THR_SLEEP]: Likewise.
This ChangeLog entry was the result of a result of botched commit
which resulted in the ChangeLog update being checked in, while
the actual code code itself did not make it to CVS.
This patch deletes the entry in gdb/ChangeLog titled:
mep: define gdbarch_pc_regnum instead of gdbarch_write_pc.

--enable-64-bit-bfd. Basically the issue happens when dealing with "bl"
instructions: GDB does branch destination calculation and (wrongly)
sign-extends the PC. Here is a piece of his original message explaining
the problem:

Anyway, the fix is simple and Andrew himself provided it for us. It
took a while for me to figure out how to trigger the bug (in order to
write a testcase for it), but I finally made it.
The attached patch fixes the problem (by casting to `unsigned long'
instead of just `long'), and also includes a testcase to reproduce the
issue.

"signedness" is more typical.

This enables -Wpointer-sign by default.
I've checked that --enable-targets=all builds fine with the following
as --host, on x86_64 Fedora 17 --build:
x86_64 GNU/Linux
i386 GNU/Linux
i386 MinGW-w64

OK?

This is the remaining issue impeding GDB to build with "-Wpointer-sign
