/* This module provides three functions: mipscoff_symfile_init,
|
1992-04-12 06:40:04 +00:00
|
|
|
|
which initializes to read a symbol file; mipscoff_new_init, which
|
1991-09-17 05:17:00 +00:00
|
|
|
|
discards existing cached information when all symbols are being
|
|
|
|
|
discarded; and mipscoff_symfile_read, which reads a symbol table
|
|
|
|
|
from a file.
|
|
|
|
|
|
|
|
|
|
mipscoff_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. mipscoff_psymtab_to_symtab() is called indirectly through
|
1992-03-03 23:26:26 +00:00
|
|
|
|
a pointer in the psymtab to do this.
|
|
|
|
|
|
|
|
|
|
ECOFF symbol tables are mostly written in the byte order of the
|
|
|
|
|
target machine. However, one section of the table (the auxiliary
|
|
|
|
|
symbol information) is written in the host byte order. There is a
|
|
|
|
|
bit in the other symbol info which describes which host byte order
|
|
|
|
|
was used. ECOFF thereby takes the trophy from Intel `b.out' for
|
|
|
|
|
the most brain-dead adaptation of a file format to byte order.
|
|
|
|
|
|
|
|
|
|
This module can read all four of the known byte-order combinations,
|
1993-03-22 20:22:54 +00:00
|
|
|
|
on any type of host. */

Naming follows gcc convention.
* config/{*.mt, *.mh}: All target and host makefile fragment
config files moved to an appropriate config/<cpu> subdirectory.
* nm-*, xm-*, tm-*: All native, host, and target files, which
get linked to nm.h, xm.h, and tm.h respectively by configure,
moved to appropriate config/<cpu> subdirectory.
* nm-sysv4.h, xm-sysv4.h, tm-sysv4.h, tm-sunos.h, nm-trash.h:
Native, host, and target files that are common across more than
one cpu architecture and included by one of the configured
native, host, or target files, get moved to config directory.
* Makefile.in (INCLUDE_CFLAGS): Add -I${srcdir}/config to
pick up native, host, or target include files moved to one of
the config subdirectories, and that are included by other files.
* Makefile.in (alldeps.mak): Modify to account for new config
directory structure.
* alldeps.mak, depend: Update for new config directory structure.
* config/*/[ntx]m-*.h: Modify all files that include other
[ntx]m-*.h files to use path relative to gdb/config. I.E.
"a29k/tm-ultra3.h" includes "a29k/tm-29k.h" rather than just
"tm-29k.h".

* mipsread.c (tm-mips.h): Include mips/tm-mips.h.
* i860-pinsn.c (tm-i860.h): Include i860/tm-i860.h.
* configure.in: Default gdb_host_cpu to host_cpu, and remap
the ones where the default is not unique or different than the
config subdirectory name. Similarly, handle gdb_target_cpu.
Modify configure.in as appropriate to make use of gdb_host_cpu
and gdb_target_cpu to find makefile fragments and make links.

Create and use macros for iterating on symtabs, psymtabs, msymbols.
* minsyms.c (iterate_over_msymbols): Remove; clunky and slow.
* symfile.h, symtab.h (iterate_over_msymbols): Remove prototype
* coffread.c (coff_symfile_read): iterate_over_symtabs => ALL_SYMTABS.
(patch_opaque_types): Avoid dummy args and result.
* objfiles.c (have_partial_symbols, have_full_symbols,
have_minimal_symbols): explicit iteration => ALL_OBJFILES; simplify.
(iterate_over_objfiles, iterate_over_symtabs,
iterate_over_psymtabs): Remove, clunky and slow.
* objfiles.h: Replace iterate_over_* prototypes with ALL_SYMTABS,
ALL_PSYMTABS, and ALL_MSYMBOLS macros.
* symmisc.c (dump_symtab, dump_psymtab, dump_msymbols,
dump_objfile): Remove dummy args and results. Move filename
comparisons to callers.
(printsyms_command, printpsyms_command, printmsyms_command,
printobjfiles_command): iterate_over_* => ALL_*. Compare filenames.
* symtab.c (lookup_symtab_1, lookup_symtab, lookup_partial_symtab,
lookup_symbol, find_main_psymtab, find_pc_symtab, sources_info,
list_symbols, make_symbol_completion_list): Replace explicit
iteration with ALL_SYMTABS, ALL_PSYMTABS, or ALL_MSYMBOLS.
Eliminate Dijkstra flag crap, break out of loops with gotos.
(lookup_symtab_1): Protect '/' tests from short filenames.
(cplus_mangled_symbol): Move inline into lookup_symbol.
* xcoffexec.c (relocate_objfile_msymbols): Remove poor hack.
(relocate_minimal_symbol): Move inline to vmap_symtab.
(vmap_symtab): Replace iteration with ALL_OBJFILES,
iterate_over_msymbols with ALL_MSYMBOLS.
Misc cleanup prior to release.
* dwarfread.c (dwarf_build_psymtabs): Remove mainline test.
* mipsread.c (compare_symtabs, compare_psymtabs): Remove, unused.
* mipsread.c: Add prototypes for all static functions.
* symmisc.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl): Remove, unused.
* xcoffread.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl): Remove 2nd
unused copy!
* buildsym.c (define_symbol): Handle global register variables
(from Pierre Willard). Complain if register numbers are too large.

unions, and enums at this point. This is a bug in the

|
|
original design (that has been fixed with the recent
|
|
|
|
|
addition of the stStruct, stUnion, and stEnum symbol
|
|
|
|
|
types.) The way you can tell is if/when you see a variable
|
|
|
|
|
or field of that type. In that case the variable's type
|
|
|
|
|
(in the AUX table) says if the type is struct, union, or
|
|
|
|
|
enum, and points back to the stBlock here. So you can
|
|
|
|
|
patch the tag kind up later - but only if there actually is
|
|
|
|
|
a variable or field of that type.
|
|
|
|
|
|
|
|
|
|
So until we know for sure, we will guess at this point.
|
|
|
|
|
The heuristic is:
|
|
|
|
|
If the first member has index==indexNil or a void type,
|
|
|
|
|
assume we have an enumeration.
|
|
|
|
|
Otherwise, if there is more than one member, and all
|
|
|
|
|
the members have offset 0, assume we have a union.
|
|
|
|
|
Otherwise, assume we have a struct.
|
|
|
|
|
|
|
|
|
|
The heuristic could guess wrong in the case of of an
|
|
|
|
|
enumeration with no members or a union with one (or zero)
|
|
|
|
|
members, or when all except the last field of a struct have
|
|
|
|
|
width zero. These are uncommon and/or illegal situations,
|
|
|
|
|
and in any case guessing wrong probably doesn't matter
|
|
|
|
|
much.
|
|
|
|
|
|
|
|
|
|
But if we later do find out we were wrong, we fixup the tag
|
|
|
|
|
kind. Members of an enumeration must be handled
|
|
|
|
|
differently from struct/union fields, and that is harder to
|
|
|
|
|
patch up, but luckily we shouldn't need to. (If there are
|
|
|
|
|
any enumeration members, we can tell for sure it's an enum
|
|
|
|
|
here.) */

Create and use macros for iterating on symtabs, psymtabs, msymbols.
* minsyms.c (iterate_over_msymbols): Remove; clunky and slow.
* symfile.h, symtab.h (iterate_over_msymbols): Remove prototype
* coffread.c (coff_symfile_read): iterate_over_symtabs => ALL_SYMTABS.
(patch_opaque_types): Avoid dummy args and result.
* objfiles.c (have_partial_symbols, have_full_symbols,
have_minimal_symbols): explicit iteration => ALL_OBJFILES; simplify.
(iterate_over_objfiles, iterate_over_symtabs,
iterate_over_psymtabs): Remove, clunky and slow.
* objfiles.h: Replace iterate_over_* prototypes with ALL_SYMTABS,
ALL_PSYMTABS, and ALL_MSYMBOLS macros.
* symmisc.c (dump_symtab, dump_psymtab, dump_msymbols,
dump_objfile): Remove dummy args and results. Move filename
comparisons to callers.
(printsyms_command, printpsyms_command, printmsyms_command,
printobjfiles_command): iterate_over_* => ALL_*. Compare filenames.
* symtab.c (lookup_symtab_1, lookup_symtab, lookup_partial_symtab,
lookup_symbol, find_main_psymtab, find_pc_symtab, sources_info,
list_symbols, make_symbol_completion_list): Replace explicit
iteration with ALL_SYMTABS, ALL_PSYMTABS, or ALL_MSYMBOLS.
Eliminate Dijkstra flag crap, break out of loops with gotos.
(lookup_symtab_1): Protect '/' tests from short filenames.
(cplus_mangled_symbol): Move inline into lookup_symbol.
* xcoffexec.c (relocate_objfile_msymbols): Remove poor hack.
(relocate_minimal_symbol): Move inline to vmap_symtab.
(vmap_symtab): Replace iteration with ALL_OBJFILES,
iterate_over_msymbols with ALL_MSYMBOLS.
Misc cleanup prior to release.
* dwarfread.c (dwarf_build_psymtabs): Remove mainline test.
* mipsread.c (compare_symtabs, compare_psymtabs): Remove, unused.
* mipsread.c: Add prototypes for all static functions.
* symmisc.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl): Remove, unused.
* xcoffread.c (dump_symtab_lines, dump_symtabs, dump_last_symtab,
dump_blockvector, dump_block, dump_addrchass, dump_namespace,
dump_symbol, dump_type, dump_linetable, dump_strtbl): Remove 2nd
unused copy!
* buildsym.c (define_symbol): Handle global register variables
(from Pierre Willard). Complain if register numbers are too large.

/* Add a new linenumber entry (LINENO,ADR) to a linevector LT.

to describe it, LAST is used to detect these continuation lines.
|
|
|
|
|
|
|
|
|
|
Combining lines with the same line number seems like a bad idea.
|
|
|
|
|
E.g: There could be a line number entry with the same line number after the
|
|
|
|
|
prologue and GDB should not ignore it (this is a better way to find
|
|
|
|
|
a prologue than mips_skip_prologue).
|
|
|
|
|
But due to the compressed line table format there are line number entries
|
|
|
|
|
for the same line which are needed to bridge the gap to the next
|
|
|
|
|
line number entry. These entries have a bogus address info with them
|
|
|
|
|
and we are unable to tell them from intended duplicate line number
|
|
|
|
|
entries.
|
|
|
|
|
This is another reason why -ggdb debugging format is preferable. */
