        .uleb128 0x25

The DW_AT_GNU_call_site_value uses a DW_OP_GNU_regval_type
operation, referencing register 0x3f=63, which is $f31,
an 8-byte floating register. In that register, the value is
stored using the usual 8-byte float format:

    (gdb) info float
    f31            99.0 (raw 0x4058c00000000000)

The current code evaluating DW_OP_GNU_regval_type operations
currently is (dwarf2expr.c:execute_stack_op):

            result = (ctx->funcs->read_reg) (ctx->baton, reg);
            result_val = value_from_ulongest (address_type, result);
            result_val = value_from_contents (type,
                                              value_contents_all (result_val));

What the ctx->funcs->read_reg function does is read the contents
of the register as if it contained an address. The rest of the code
continues that assumption, thinking it's OK to then use that to
create an address/ulongest struct value, which we then re-type
to the type specified by DW_OP_GNU_regval_type.

We're getting 0.0 above because the read_reg implementations
end up treating the contents of the FP register as an integral,
reading only 4 out of the 8 bytes. Being a big-endian target,
we read the high-order ones, which gives us zero.

This patch fixes the problem by introducing a new callback to
read the contents of a register as a given type, and then adjust
the handling of DW_OP_GNU_regval_type to use that new callback.

    watchpoint in the breakpoint list, because we need to force the
    target to single-step all the way, to evaluate the watchpoint's
    value at each step.

There's no reason for the "catchpoint" TARGET_WAITKIND_XXXs to consult

again, gdbserver always replies a regular trap on initial connection,

testsuite/gdb.dwarf2: dw2-case-insensitive.exp: p fuNC_lang fails on arm

dw2-case-insensitive.exp: p fuNC_lang fails on arm. The problem occurs
when thumb mode code is generated. On ARM last bit of function pointer
value indicates whether the target function is an ARM (if 0) or Thumb
(if 1) routine. The PC address should refer to actual address in
either case. This patch adds new compile unit and function labels to
code which act as address ranges of compile unit and functions in
debug information. Therefore address ranges will have correct
addresses and not the ones with an incremented least significant bit.
This patch has been tested on x86_64 and arm machines.

GDB/MI: Add new "--language LANG" command option.

Frontend sometimes need to evaluate expressions that are
language-specific. For instance, Eclipse uses the following
expression to determine the size of an address on the target:

    -data-evaluate-expression "sizeof (void*)"

Unfortunately, if the main of the program being debugged is not C,
this may not work. For instance, if the main is in Ada, you get...

    -data-evaluate-expression "sizeof (void*)"
    ^error,msg="No definition of \"sizeof\" in current context."

... and apparently decides to stop the debugging session as a result.
The  recommendation sent was to specifically set the language to C
before trying to evaluate the expression.  Something such as:

    1. save current language
    2. set language c
    3. -data-evaluate-expression "sizeof (void*)"
    4. Restore language

This has the same disadvantages as the ones outlined in the "Context
Management" section of the GDB/MI documentation regarding setting
the current thread or the current frame, thus recommending the use of
general command-line switches such as --frame, or --thread instead.

This patch follows the same steps for the language, adding a similar
new command option: --language LANG. Example of use:

    -data-evaluate-expression --language c "sizeof (void*)"
    ^done,value="4"

        * mi/mi-parse.h (struct mi_parse) <language>: New field.

New function cli-utils.c:extract_arg_const

This function provides the exact same functionality as extract_arg,
except that it takes a "const char**" instead of a "char **".
It allows us also to re-implement extract_arg almost as a simple
wrapper around the new function.
