/* This module provides three functions: dbx_symfile_init,
|
|
|
|
|
|
which initializes to read a symbol file; dbx_new_init, which
|
|
|
|
|
|
discards existing cached information when all symbols are being
|
|
|
|
|
|
discarded; and dbx_symfile_read, which reads a symbol table
|
|
|
|
|
|
from a file.
|
|
|
|
|
|
|
|
|
|
|
|
dbx_symfile_read only does the minimum work necessary for letting the
|
|
|
|
|
|
user "name" things symbolically; it does not read the entire symtab.
|
|
|
|
|
|
Instead, it reads the external and static symbols and puts them in partial
|
|
|
|
|
|
symbol tables. When more extensive information is requested of a
|
|
|
|
|
|
file, the corresponding partial symbol table is mutated into a full
|
|
|
|
|
|
fledged symbol table by going back and reading the symbols
|
|
|
|
|
|
for real. dbx_psymtab_to_symtab() is the function that does this */

remove gdb_string.h
This removes gdb_string.h. This patch is purely mechanical. I
created it by running the two commands:
git rm common/gdb_string.h

(Changes from Daniel Berlin, with revisions by Jim Blandy.)
Abstract out operations specific to particular C++ ABI's, and
invoke them through a function table. This removes the C++ ABI
dependencies scattered throughout the code, and allows us to
cleanly add support for new C++ ABI's.
* cp-abi.h, cp-abi.h, gnu-v2-abi.c, hpacc-abi.c: New files.
* c-typeprint.c, c-valprint.c, dbxread.c, eval.c, gdbtypes.c,
jv-typeprint.c, linespec.c, symtab.c, typeprint.c, valops.c:
#include "cp-abi.h". These files all use functions now declared
there.
* symtab.h (OPNAME_PREFIX_P, VTBL_PREFIX_P, DESTRUCTOR_PREFIX_P):
Deleted. These services are now provided by functions declared in
cp-abi.h.
* value.h (value_rtti_type, value_virtual_fn_field): Same.
* values.c (value_virtual_fn_field): Same, for this definition.
* valops.c (value_rtti_type): Same.
* c-typeprint.c (c_type_print_base): Use the functions from
"cp-abi.h", instead of the old macros, or hard-coded ABI-specific
tests.
* dbxread.c (record_minimal_symbol): Same.
* gdbtypes.c (get_destructor_fn_field, virtual_base_index,
virtual_base_index_skip_primaries): Same.
* jv-typeprint.c (java_type_print_base): Same.
* linespec.c (find_methods, decode_line_1): Same.
* symtab.c (gdb_mangle_name): Same.
* Makefile.in (SFILES): Add the new .c files mentioned above.
(cp_abi_h): New variable.
(COMMON_OBS): Add gnu-v2-abi.o, hpacc-abi.o, and cp-abi.o.
(cp-abi.o, gnu-v2-abi.o, hpacc-abi.o): New targets.
(c-typeprint.o, c-valprint.o, dbxread.o, eval.o, gdbtypes.o,
jv-typeprint.o, symtab.o, linespec.o, typeprint.o, valops.o): Add
dependency on $(cp_abi_h).

Abstract out operations specific to particular C++ ABI's, and
invoke them through a function table. This removes the C++ ABI
dependencies scattered throughout the code, and allows us to
cleanly add support for new C++ ABI's.
* cp-abi.h, cp-abi.h, gnu-v2-abi.c, hpacc-abi.c: New files.

jv-typeprint.c, linespec.c, symtab.c, typeprint.c, valops.c:
#include "cp-abi.h". These files all use functions now declared
there.

Deleted. These services are now provided by functions declared in
cp-abi.h.

* values.c (value_virtual_fn_field): Same, for this definition.
* valops.c (value_rtti_type): Same.

"cp-abi.h", instead of the old macros, or hard-coded ABI-specific
tests.

* linespec.c (find_methods, decode_line_1): Same.
* symtab.c (gdb_mangle_name): Same.
* Makefile.in (SFILES): Add the new .c files mentioned above.
(cp_abi_h): New variable.
(COMMON_OBS): Add gnu-v2-abi.o, hpacc-abi.o, and cp-abi.o.

use bound_minsym as result for lookup_minimal_symbol et al
This patch changes a few minimal symbol lookup functions to return a
bound_minimal_symbol rather than a pointer to the minsym. This change
helps prepare gdb for computing a minimal symbol's address at the
point of use.
Note that this changes even those functions that ostensibly search a
single objfile. That was necessary because, in fact, those functions
can search an objfile and its separate debug objfiles; and it is
important for the caller to know in which objfile the minimal symbol
was actually found.
The bulk of this patch is mechanical.

This patch changes a few minimal symbol lookup functions to return a

Note that this changes even those functions that ostensibly search a

|
|
to global and static variables. The stab for a global or static
|
|
|
|
|
|
variable doesn't give us any indication of which section it's in,
|
|
|
|
|
|
so we can't tell immediately which offset in
|
|
|
|
|
|
objfile->section_offsets we should apply to the variable's
|
|
|
|
|
|
address.
|
|
|
|
|
|
|
|
|
|
|
|
We could certainly find out which section contains the variable
|
|
|
|
|
|
by looking up the variable's unrelocated address with
|
|
|
|
|
|
find_pc_section, but that would be expensive; this is the
|
|
|
|
|
|
function that constructs the partial symbol tables by examining
|
|
|
|
|
|
every symbol in the entire executable, and it's
|
|
|
|
|
|
performance-critical. So that expense would not be welcome. I'm
|
|
|
|
|
|
not sure what to do about this at the moment.
|
|
|
|
|
|
|
|
|
|
|
|
What we have done for years is to simply assume that the .data
|
|
|
|
|
|
section's offset is appropriate for all global and static
|
|
|
|
|
|
variables. Recently, this was expanded to fall back to the .bss
|
|
|
|
|
|
section's offset if there is no .data section, and then to the
|
|
|
|
|
|
.rodata section's offset. */

use bound_minsym as result for lookup_minimal_symbol et al
This patch changes a few minimal symbol lookup functions to return a
bound_minimal_symbol rather than a pointer to the minsym. This change
helps prepare gdb for computing a minimal symbol's address at the
point of use.
Note that this changes even those functions that ostensibly search a
single objfile. That was necessary because, in fact, those functions
can search an objfile and its separate debug objfiles; and it is
important for the caller to know in which objfile the minimal symbol
was actually found.
The bulk of this patch is mechanical.

elfstab_offset_sections currently does not muck

with the text offset (there is no Ttext.text

symbol), we can get addr from the text offset. If

elfstab_offset_sections ever starts dealing with
|
|
|

the text offset, and we still need to do this, we
|

need to invent a SECT_OFF_ADDR_KLUDGE or something. */
