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. gdb/ChangeLog 2014-12-12 Phil Muldoon <pmuldoon@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Tom Tromey <tromey@redhat.com> * NEWS: Update. * symtab.h (struct symbol_computed_ops) <generate_c_location>: New field. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_language_defn): Update. * m2-lang.c (m2_language_defn): Update. * language.h (struct language_defn) <la_get_compile_instance, la_compute_program>: New fields. * language.c (unknown_language_defn, auto_language_defn) (local_language_defn): Update. * jv-lang.c (java_language_defn): Update. * go-lang.c (go_language_defn): Update. * f-lang.c (f_language_defn): Update. * dwarf2loc.h (dwarf2_compile_property_to_c): Declare. * dwarf2loc.c (dwarf2_compile_property_to_c) (locexpr_generate_c_location, loclist_generate_c_location): New functions.
