elfread.c (coff_symfile_finish): Add function, prototype, and
add to the xxxx_sym_fns struct for each file type. Also reformat

symbol file specific info in the per-objfile memory region.

free_header_files(), called from dbx_symfile_finish(), and

routine for the objfile before deallocating other stuff.

than struct sym_fns pointer.

locates the correct sym_fns struct for the given objfile.

for better support of mapped symbol tables.

DESCRIPTION
|
|
|
|
|
|
1996-02-16 22:14:47 +00:00
|
|
|
|
Given pointers to pointers to two partial symbol table entries,
|
|
|
|
|
compare them by name and return -N, 0, or +N (ala strcmp).
|
|
|
|
|
Typically used by sorting routines like qsort().

NOTES
|
|
|
|
|
|
|
|
|
|
Does direct compare of first two characters before punting
|
|
|
|
|
and passing to strcmp for longer compares. Note that the
|
|
|
|
|
original version had a bug whereby two null strings or two
|
|
|
|
|
identically named one character strings would return the
|
|
|
|
|
comparison of memory following the null byte.

Add code to demangle and cache C++ symbol names. Use macro form

exceptions. The exceptions are sysvr4 shared libraries, whose

Section offsets are built similarly, except that they are built

by adding addr in all cases because there is no clear mapping

|
|

from section_offsets into actual sections. Note that solib.c

has a different algorythm for finding section offsets.

/* Set the initial language.

|

|
|
|
|
A better solution would be to record the language in the psymtab when reading
|
|
|
|
|
partial symbols, and then use it (if known) to set the language. This would
|
|
|
|
|
be a win for formats that encode the language in an easily discoverable place,
|
|
|
|
|
such as DWARF. For stabs, we can jump through hoops looking for specially
|
|
|
|
|
named symbols or try to intuit the language from the specific type of stabs
|
|
|
|
|
we find, but we can't do that until later when we read in full symbols.

breakpoint_re_set.

static.

Don't muck with objfile->num_sections now that all the symbol
readers set it.
* elfread.c: Clean up obsolete comment about handling only DWARF.
* paread.c: Remove comment about how we should use an "ordinary"
file format with an hppa suffix. There is nothing ordinary about SOM.

/* clear_symtab_users_once:
|
|
|
|
|
|
|
|
|
|
This function is run after symbol reading, or from a cleanup.
|
|
|
|
|
If an old symbol table was obsoleted, the old symbol table
|
|
|
|
|
has been blown away, but the other GDB data structures that may
|
|
|
|
|
reference it have not yet been cleared or re-directed. (The old
|
|
|
|
|
symtab was zapped, and the cleanup queued, in free_named_symtab()
|
|
|
|
|
below.)
|
|
|
|
|
|
|
|
|
|
This function can be queued N times as a cleanup, or called
|
|
|
|
|
directly; it will do all the work the first time, and then will be a
|
|
|
|
|
no-op until the next time it is queued. This works by bumping a
|
|
|
|
|
counter at queueing time. Much later when the cleanup is run, or at
|
|
|
|
|
the end of symbol processing (in case the cleanup is discarded), if
|
|
|
|
|
the queued count is greater than the "done-count", we do the work
|
|
|
|
|
and set the done-count to the queued count. If the queued count is
|
|
|
|
|
less than or equal to the done-count, we just ignore the call. This
|
|
|
|
|
is needed because reading a single .o file will often replace many
|
|
|
|
|
symtabs (one per .h file, for example), and we don't want to reset
|
|
|
|
|
the breakpoints N times in the user's face.
|
|
|
|
|
|
|
|
|
|
The reason we both queue a cleanup, and call it directly after symbol
|
|
|
|
|
reading, is because the cleanup protects us in case of errors, but is
|
|
|
|
|
discarded if symbol reading is successful. */

/* OVERLAYS:
|
|
|
|
|
The following code implements an abstraction for debugging overlay sections.
|
|
|
|
|
|
|
|
|
|
The target model is as follows:
|
|
|
|
|
1) The gnu linker will permit multiple sections to be mapped into the
|
|
|
|
|
same VMA, each with its own unique LMA (or load address).
|
|
|
|
|
2) It is assumed that some runtime mechanism exists for mapping the
|
|
|
|
|
sections, one by one, from the load address into the VMA address.
|
|
|
|
|
3) This code provides a mechanism for gdb to keep track of which
|
|
|
|
|
sections should be considered to be mapped from the VMA to the LMA.
|
|
|
|
|
This information is used for symbol lookup, and memory read/write.
|
|
|
|
|
For instance, if a section has been mapped then its contents
|
|
|
|
|
should be read from the VMA, otherwise from the LMA.
|
|
|
|
|
|
|
|
|
|
Two levels of debugger support for overlays are available. One is
|
|
|
|
|
"manual", in which the debugger relies on the user to tell it which
|
|
|
|
|
overlays are currently mapped. This level of support is
|
|
|
|
|
implemented entirely in the core debugger, and the information about
|
|
|
|
|
whether a section is mapped is kept in the objfile->obj_section table.
|
|
|
|
|
|
|
|
|
|
The second level of support is "automatic", and is only available if
|
|
|
|
|
the target-specific code provides functionality to read the target's
|
|
|
|
|
overlay mapping table, and translate its contents for the debugger
|
|
|
|
|
(by updating the mapped state information in the obj_section tables).
|
|
|
|
|
|
|
|
|
|
The interface is as follows:
|
|
|
|
|
User commands:
|
|
|
|
|
overlay map <name> -- tell gdb to consider this section mapped
|
|
|
|
|
overlay unmap <name> -- tell gdb to consider this section unmapped
|
|
|
|
|
overlay list -- list the sections that GDB thinks are mapped
|
|
|
|
|
overlay read-target -- get the target's state of what's mapped
|
|
|
|
|
overlay off/manual/auto -- set overlay debugging state
|
|
|
|
|
Functional interface:
|
|
|
|
|
find_pc_mapped_section(pc): if the pc is in the range of a mapped
|
|
|
|
|
section, return that section.
|
|
|
|
|
find_pc_overlay(pc): find any overlay section that contains
|
|
|
|
|
the pc, either in its VMA or its LMA
|
|
|
|
|
overlay_is_mapped(sect): true if overlay is marked as mapped
|
|
|
|
|
section_is_overlay(sect): true if section's VMA != LMA
|
|
|
|
|
pc_in_mapped_range(pc,sec): true if pc belongs to section's VMA
|
|
|
|
|
pc_in_unmapped_range(...): true if pc belongs to section's LMA
|
|
|
|
|
overlay_mapped_address(...): map an address from section's LMA to VMA
|
|
|
|
|
overlay_unmapped_address(...): map an address from section's VMA to LMA
|
|
|
|
|
symbol_overlayed_address(...): Return a "current" address for symbol:
|
|
|
|
|
either in VMA or LMA depending on whether
|
|
|
|
|
the symbol's section is currently mapped

/* Target Overlays for the "Simplest" overlay manager:
|
|
|
|
|
|
|
|
|
|
This is GDB's default target overlay layer. It works with the
|
|
|
|
|
minimal overlay manager supplied as an example by Cygnus. The
|
|
|
|
|
entry point is via a function pointer "target_overlay_update",
|
|
|
|
|
so targets that use a different runtime overlay manager can
|
|
|
|
|
substitute their own overlay_update function and take over the
|
|
|
|
|
function pointer.
|
|
|
|
|
|
|
|
|
|
The overlay_update function pokes around in the target's data structures
|
|
|
|
|
to see what overlays are mapped, and updates GDB's overlay mapping with
|
|
|
|
|
this information.
|
|
|
|
|
|
|
|
|
|
In this simple implementation, the target data structures are as follows:
|
|
|
|
|
unsigned _novlys; /# number of overlay sections #/
|
|
|
|
|
unsigned _ovly_table[_novlys][4] = {
|
|
|
|
|
{VMA, SIZE, LMA, MAPPED}, /# one entry per overlay section #/
|
|
|
|
|
{..., ..., ..., ...},
|
|
|
|
|
}
|
|
|
|
|
unsigned _novly_regions; /# number of overlay regions #/
|
|
|
|
|
unsigned _ovly_region_table[_novly_regions][3] = {
|
|
|
|
|
{VMA, SIZE, MAPPED_TO_LMA}, /# one entry per overlay region #/
|
|
|
|
|
{..., ..., ...},
|
|
|
|
|
}
|
|
|
|
|
These functions will attempt to update GDB's mappedness state in the
|
|
|
|
|
symbol section table, based on the target's mappedness state.
|
|
|
|
|
|
|
|
|
|
To do this, we keep a cached copy of the target's _ovly_table, and
|
|
|
|
|
attempt to detect when the cached copy is invalidated. The main
|
|
|
|
|
entry point is "simple_overlay_update(SECT), which looks up SECT in
|
|
|
|
|
the cached table and re-reads only the entry for that section from
|
|
|
|
|
the target (whenever possible).
