/* This file contains support routines for creating, manipulating, and
|
|
|
|
|
|
destroying minimal symbol tables.
|
|
|
|
|
|
|
|
|
|
|
|
Minimal symbol tables are used to hold some very basic information about
|
|
|
|
|
|
all defined global symbols (text, data, bss, abs, etc). The only two
|
|
|
|
|
|
required pieces of information are the symbol's name and the address
|
|
|
|
|
|
associated with that symbol.
|
|
|
|
|
|
|
|
|
|
|
|
In many cases, even if a file was compiled with no special options for
|
|
|
|
|
|
debugging at all, as long as was not stripped it will contain sufficient
|
|
|
|
|
|
information to build useful minimal symbol tables using this structure.
|

|
|
|
|
|
1999-04-16 03:35:26 +02:00
|
|
|
|
Even when a file contains enough debugging information to build a full
|
|
|
|
|
|
symbol table, these minimal symbols are still useful for quickly mapping
|
|
|
|
|
|
between names and addresses, and vice versa. They are also sometimes used
|
2011-01-09 04:20:33 +01:00
|
|
|
|
to figure out what full symbol table entries need to be read in. */

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
perl -pi -e's/"gdb_string.h"/<string.h>/;' *.[chyl] */*.[chyl]

the search to that objfile. If SFILE is non-NULL, the only file-scope

Note: One instance where there may be duplicate minimal symbols with

the same name is when the symbol tables for a shared library and the
|

|
|
symbol tables for an executable contain global symbols with the same

names (the dynamic linker deals with the duplication).
|
|
|
|
|
|
|
|
|
|
|
|
It's also possible to have minimal symbols with different mangled
|
|
|
|
|
|
names, but identical demangled names. For example, the GNU C++ v3
|
|
|
|
|
|
ABI requires the generation of two (or perhaps three) copies of
|
|
|
|
|
|
constructor functions --- "in-charge", "not-in-charge", and
|
|
|
|
|
|
"allocate" copies; destructors may be duplicated as well.
|
|
|
|
|
|
Obviously, there must be distinct mangled names for each of these,
|
|
|
|
|
|
but the demangled names are all the same: S::S or S::~S. */

/* Compact duplicate entries out of a minimal symbol table by walking
|
|
|
|
|
|
through the table and compacting out entries with duplicate addresses
|
|
|
|
|
|
and matching names. Return the number of entries remaining.
|
|
|
|
|
|
|
|
|
|
|
|
On entry, the table resides between msymbol[0] and msymbol[mcount].
|
|
|
|
|
|
On exit, it resides between msymbol[0] and msymbol[result_count].
|
|
|
|
|
|
|
|
|
|
|
|
When files contain multiple sources of symbol information, it is
|
|
|
|
|
|
possible for the minimal symbol table to contain many duplicate entries.
|
|
|
|
|
|
As an example, SVR4 systems use ELF formatted object files, which
|
|
|
|
|
|
usually contain at least two different types of symbol tables (a
|
|
|
|
|
|
standard ELF one and a smaller dynamic linking table), as well as
|
|
|
|
|
|
DWARF debugging information for files compiled with -g.
|
|
|
|
|
|
|
|
|
|
|
|
Without compacting, the minimal symbol table for gdb itself contains
|
|
|
|
|
|
over a 1000 duplicates, about a third of the total table size. Aside
|
|
|
|
|
|
from the potential trap of not noticing that two successive entries
|
|
|
|
|
|
identify the same location, this duplication impacts the time required
|
|
|
|
|
|
to linearly scan the table, which is done in a number of places. So we
|
|
|
|
|
|

|
1999-04-16 03:35:26 +02:00

table is freed. The caller can free up the unused minimal symbols at
|
|
|
|
|
|
the end of the compacted region if their allocation strategy allows it.

|
|
|
|
|
|
|

Also note we only go up to the next to last entry within the loop
|

|
|
|

and then copy the last entry explicitly after the loop terminates.
|
|
|
|
|
|
|
|
|
|
|
|
Since the different sources of information for each symbol may
|
|
|
|
|
|
have different levels of "completeness", we may have duplicates
|
|
|
|
|
|
that have one entry with type "mst_unknown" and the other with a
|
|
|
|
|
|
known type. So if the one we are leaving alone has type mst_unknown,
|
|
|
|
|
|
overwrite its type with the type from the one we are compacting out. */

/* Add the minimal symbols in the existing bunches to the objfile's official
|
|
|
|
|
|
minimal symbol table. In most cases there is no minimal symbol table yet
|
|
|
|
|
|
for this objfile, and the existing bunches are used to create one. Once
|
|
|
|
|
|
in a while (for shared libraries for example), we add symbols (e.g. common
|
|
|
|
|
|
symbols) to an existing objfile.
|
|
|
|
|
|
|
|
|
|
|
|
Because of the way minimal symbols are collected, we generally have no way
|
|
|
|
|
|
of knowing what source language applies to any particular minimal symbol.
|
|
|
|
|
|
Specifically, we have no way of knowing if the minimal symbol comes from a
|
|
|
|
|
|
C++ compilation unit or not. So for the sake of supporting cached
|
|
|
|
|
|
demangled C++ names, we have no choice but to try and demangle each new one
|
|
|
|
|
|
that comes in. If the demangling succeeds, then we assume it is a C++
|
|
|
|
|
|
symbol and set the symbol's language and demangled name fields
|
|
|
|
|
|
appropriately. Note that in order to avoid unnecessary demanglings, and
|
|
|
|
|
|
allocating obstack space that subsequently can't be freed for the demangled
|
|
|
|
|
|
names, we mark all newly added symbols with language_auto. After
|
|
|
|
|
|
compaction of the minimal symbols, we go back and scan the entire minimal
|
|
|
|
|
|
symbol table looking for these new symbols. For each new symbol we attempt
|
|
|
|
|
|
to demangle it, and if successful, record it as a language_cplus symbol
|
|
|
|
|
|
and cache the demangled form on the symbol obstack. Symbols which don't
|
|
|
|
|
|
demangle are marked as language_unknown symbols, which inhibits future
|
2011-01-09 04:20:33 +01:00
|
|
|
|
attempts to demangle them if we later add more minimal symbols. */
