Expand preprocessor macros in C expressions.
* c-lang.h: #include "macroexp.h", for macro_lookup_ftype.
(scan_macro_expansion, scanning_macro_expansion,
finished_macro_expansion): New function declarations.
(expression_macro_lookup_func, expression_macro_lookup_baton): New
variable declarations.
* parser-defs.h (expression_context_pc): New declaration.
* parse.c (expression_context_pc): New variable.
(parse_exp_1): Set expression_context_pc, as well as
expression_context_block.
* c-exp.y (yylex): If we're not already reading the result of a
macro expansion, try to macro-expand the next token. When we're
done scanning a macro expansion, switch back to the mainline text.
Commas and `if's in a macro's expansion don't terminate the input.
* c-lang.c: #include "macroscope.h" and "gdb_assert.h".
(macro_original_text, macro_expanded_text,
expression_macro_lookup_func, expression_macro_lookup_baton): New
variables.
(scan_macro_expansion, scanning_macro_expansion,
finished_macro_expansion, scan_macro_cleanup, null_macro_lookup,
c_preprocess_and_parse): New functions.
(c_language_defn, cplus_language_defn, asm_language_defn): Call
c_preprocess_and_parse, instead of c_parse.
* Makefile.in (c_lang_h): Note that this #includes macroexp.h.
(c-lang.o): Note dependency on macroscope.h and gdb_assert.h.

|
|
|
|
|
|
|
|
|
|
Some object/debugging file formats (DWARF version 1, COFF, etc) do not
|
|
|
|
|
define fundamental types such as "int" or "double". Others (stabs or
|
|
|
|
|
DWARF version 2, etc) do define fundamental types. For the formats which
|
|
|
|
|
don't provide fundamental types, gdb can create such types using this
|
|
|
|
|
function.

|
|
|

|
|
FIXME: Some compilers distinguish explicitly signed integral types
|
|
|
|
|
(signed short, signed int, signed long) from "regular" integral types
|
|
|
|
|
(short, int, long) in the debugging information. There is some dis-
|
|
|
|
|
agreement as to how useful this feature is. In particular, gcc does
|
|
|
|
|
not support this. Also, only some debugging formats allow the
|
|
|
|
|
distinction to be passed on to a debugger. For now, we always just
|
|
|
|
|
use "short", "int", or "long" as the type name, for both the implicit
|
|
|
|
|
and explicitly signed types. This also makes life easier for the
|
|
|
|
|
gdb test suite since we don't have to account for the differences
|
|
|
|
|
in output depending upon what the compiler and debugging format
|
|
|
|
|
support. We will probably have to re-examine the issue when gdb
|
|
|
|
|
starts taking it's fundamental type information directly from the
|
|
|
|
|
debugging information supplied by the compiler. fnf@cygnus.com */

/* When we find that lexptr (the global var defined in parse.c) is

scan_macro_expansion to save the old lexptr here and point lexptr
|
|

into the expanded text. When we reach the end of that, we call

end_macro_expansion to pop back to the value we saved here. The

macro expansion code promises to return only fully-expanded text,

expansion beforehand, and then hand that to lexptr. But we don't

really know where the expression ends. Remember, in a command like

it's simply wrong to try to macro-expand the whole thing at once. */
