As Pedro suggested on gdb-patches@ (see
https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this
change makes symbol lookup functions return a structure that includes
both the symbol found and the block in which it was found. This makes
it possible to get rid of the block_found global variable and thus makes
block hunting explicit.

This final patch adds the new "compile" command and subcommands, and
all the machinery needed to make it work.
A shared library supplied by gcc is used for all communications with
gcc. Types and most aspects of symbols are provided directly by gdb
to the compiler using this library.
gdb provides some information about the user's code using plain text.
Macros are emitted this way, and DWARF location expressions (and
bounds for VLA) are compiled to C code.
This hybrid approach was taken because, on the one hand, it is better
to provide global declarations and such on demand; but on the other
hand, for local variables, translating DWARF location expressions to C
was much simpler than exporting a full compiler API to gdb -- the same
result, only easier to implement, understand, and debug.
In the ordinary mode, the user's expression is wrapped in a dummy
function. After compilation, gdb inserts the resulting object code
into the inferior, then calls this function.
Access to local variables is provided by noting which registers are
used by location expressions, and passing a structure of register
values into the function. Writes to registers are supported by
copying out these values after the function returns.
This approach was taken so that we could eventually implement other
more interesting features based on this same infrastructure; for
example, we're planning to investigate inferior-side breakpoint
conditions.

Currently there are many calls to help_list that pass the constant -1
as the "class" value. However, the parameter is declared as being of
type enum command_class, and uses of the constant violate this
abstraction.
This patch fixes the error everywhere it occurs in the gdb sources.
Tested by rebuilding.

Hi,
When I add another name of language, I find field 'la_name' can be
'const char *'. This patch is to constify it.
gdb:
2013-11-07 Yao Qi <yao@codesourcery.com>
* language.c (language_str): Return const char *.
(add_language): Add const to 'language_names'
* language.h (struct language_defn) <la_name>: Add const.
(language_str: Update declaration.
This is a follow-up series to move language stuff out of varobj.c.
This patch adds a new field la_varobj_ops in struct language_defn so
that each language has varobj-related options. Not every language
supports varobj, and the operations are identical to operations of c
languages.
'struct language_defn' is the ideal place to save all language-related
operations. After this patch, some cleanups can be done in patch 2/2,
which removes language-related stuff completely from varobj.c.
Regression tested on x86_64-linux.

Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
The purpose of this patch is to better support renamings in the
"info locals" command. Consider ...
procedure Foo is
GV : Integer renames Pck.Global_Variable;
begin
Increment (GV); -- STOP
end Foo;
... Pck.Global_Variable is just an integer. After having stopped at
the "STOP" line, "info locals" yields:
(gdb) info locals
gv = <error reading variable gv (Cannot access memory at address 0xffffffffffffffff)>
In reality, two things are happening:
(1) Variable "GV" does not exist, which is normal, since there is
"GV" the renaming of another variable;
(2) But to allow the user access to that renaming the same way
the code has, the compiler produces an artificial variable
whose name encodes the renaming:
gv___XR_pck__global_variable___XE
For practical reasons, the artificial variable itself is given
irrelevant types and addresses.
But the "info locals" command does not act as if it was a short-cut
of "foreach VAR in locals, print VAR". Instead it gets the value of
each VAR directly, which does not work in this case, since the variable
is artificial and needs to be decoded first.
This patch makes the "read_var_value" routine language-specific.
The old implementation of "read_var_value" gets renamed to
"default_read_var_value" and all languages now use it (unchanged
behavior), except for Ada. In Ada, the new function ada_read_var_value
checks if we have a renaming, and if so, evaluates its value, or else
defers to default_read_var_value.
gdb/ChangeLog:
* language.h (struct language_defn): New "method" la_read_var_value.
* findvar.c: #include "language.h".
(default_read_var_value): Renames read_var_value. Rewrite
function description.
(read_var_value): New function.
* value.h (default_read_var_value): Add prototype.
* ada-lang.c (ada_read_renaming_var_value, ada_read_var_value):
New functions.
(ada_language_defn): Add entry for la_read_var_value.
* c-lang.c, d-lang.c, f-lang.c, jv-lang.c, language.c,
* m2-lang.c, objc-lang.c, opencl-lang.c, p-lang.c: Update
language_defn structures to add entry for new la_read_var_value
field.
The la_get_symbol_name_match_p language hook was poorly named, as
it suggested that the function should return nonzero if the names
match, whereas it is the exact opposite. This patch therefore
renames the hook and associated typedef, as well some of the code
that uses that hook.
gdb/ChangeLog:
* language.h (symbol_name_cmp_ftype): Renames
symbol_name_match_p_ftype.
(struct language_defn)[la_get_symbol_name_cmp]: Renames
la_get_symbol_name_match_p.
* ada-lang.c (ada_get_symbol_name_cmp): Renames
ada_get_symbol_name_match_p. Update comment.
(ada_language_defn)[la_get_symbol_name_cmp]: Update value.
* linespec.c (struct symbol_matcher_data)[symbol_name_cmp]:
Renames symbol_name_match_p. Update field type.
(iterate_name_matcher, iterate_over_all_matching_symtabs): Adjust.
* c-lang.c, d-lang.c, f-lang.c, jv-lang.c, m2-lang.c, objc-lang.c,
opencl-lang.c, p-lang.c: Replace "la_get_symbol_name_match_p" by
"la_get_symbol_name_cmp" in comments.
* language.c: Likewise.
This is the meat, where we replace the old la_symbol_name_compare
language method with the new ada_get_symbol_name_match_p.
It fixes the problem when trying to insert a breakpoint on "+".
gdb/ChangeLog:
* language.h (symbol_name_match_p_ftype): New typedef.
(struct language_defn): Replace field la_symbol_name_compare
by la_get_symbol_name_match_p.

(ada_language_defn): Use it.
* linespec.c (struct symbol_matcher_data): New type.

(iterate_over_all_matching_symtabs): Pass a pointer to
a symbol_matcher_data struct to expand_symtabs_matching
instead of just the lookup name.

opencl-lang.c, p-lang.c, language.c: Delete field
la_symbol_name_compare, and replace by NULL for new field
