(Contributors): Credit Jim Blandy with macro support.
(Compilation): Explain how to get macro information into the
executable.
(Expressions): Note that preprocessor macros are expanded.

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.

(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".

finished_macro_expansion, scan_macro_cleanup, null_macro_lookup,

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.

print_insn_sh cleanup:

(gdb_print_insn_sh): Just set info->endian and use print_insn_sh.
(sh_gdbarch_init): Always use gdb_print_insn_sh.
opcodes:
* disassemble.c (disassembler): Just use print_insn_sh for bfd_arch_sh.
* sh-dis.c (LITTLE_BIT): Delete.
(print_insn_sh, print_insn_shl): Deleted.
(print_insn_shx): Renamed to
(print_insn_sh). No longer static. Handle SHmedia instructions.
Use info->endian to determine endianness.
* sh64-dis.c (print_insn_sh64, print_insn_sh64l): Delete.
(print_insn_sh64x): No longer static. Renamed to
(print_insn_sh64). Removed pfun_compact and endian arguments.
If we got an uneven address to indicate SHmedia, adjust it.
Return -2 for SHcompact instructions.

* sim-if.c (sh64_disassemble_insn): Use print_insn_sh instead of
print_insn_shl.

* p-exp.y (current_type): New static variable.
Carries the type of the expression at the position that is parsed.
(push_current_type, pop_current_type): Two new functions. Used
to store/restore current_type in expression on specific tokens.
(search_filed): New static variable. Set to one after parsing a point as
at that point only a FIELDNAME token should be searched.
(FIELDNAME): New token. After a point only a token belonging to
current_type type definition is allowed.
(all over token rules): reset and change current_type according
to rules.
(exp '[' rule): insert implicit array index field if
exp is a pascal string type.

Add macro structures to GDB's symbol tables. Nobody puts anything
in them yet.

* buildsym.c: #include "macrotab.h".
(buildsym_init): Initialize `pending_macros'.
(end_symtab): If we found macro information while reading a CU's
debugging info, do build a symtab structure for it. Make the
symtab point to the macro information, and clear the
`pending_macros' pointer which held it while we were reading the
debug info.

set new allocate and free functions for it.

* symmisc.c (print_objfile_statistics): Print statistics on the
macro bcache.
* Makefile.in: Note that buildsym.o depends on macrotab.h.
