#if !defined (OBJFILES_H)
#define OBJFILES_H
/* This structure maintains information on a per-objfile basis about the
"entry point" of the objfile, and the scope within which the entry point
exists. It is possible that gdb will see more than one objfile that is
executable, each with its own entry point.
For example, for dynamically linked executables in SVR4, the dynamic linker
code is contained within the shared C library, which is actually executable
and is run by the kernel first when an exec is done of a user executable
that is dynamically linked. The dynamic linker within the shared C library
then maps in the various program segments in the user executable and jumps
to the user executable's recorded entry point, as if the call had been made
directly by the kernel.
The traditional gdb method of using this info is to use the recorded entry
point to set the variables entry_file_lowpc and entry_file_highpc from
the debugging information, where these values are the starting address
(inclusive) and ending address (exclusive) of the instruction space in the
executable which correspond to the "startup file", I.E. crt0.o in most
cases. This file is assumed to be a startup file and frames with pc's
inside it are treated as nonexistent. Setting these variables is necessary
so that backtraces do not fly off the bottom of the stack.
Gdb also supports an alternate method to avoid running off the bottom
of the stack.
There are two frames that are "special", the frame for the function
containing the process entry point, since it has no predecessor frame,
and the frame for the function containing the user code entry point
(the main() function), since all the predecessor frames are for the
process startup code. Since we have no guarantee that the linked
in startup modules have any debugging information that gdb can use,
we need to avoid following frame pointers back into frames that might
have been built in the startup code, as we might get hopelessly
confused. However, we almost always have debugging information
available for main().
These variables are used to save the range of PC values which are valid
within the main() function and within the function containing the process
entry point. If we always consider the frame for main() as the outermost
frame when debugging user code, and the frame for the process entry
point function as the outermost frame when debugging startup code, then
all we have to do is have FRAME_CHAIN_VALID return false whenever a
frame's current PC is within the range specified by these variables.
In essence, we set "ceilings" in the frame chain beyond which we will
not proceed when following the frame chain back up the stack.
A nice side effect is that we can still debug startup code without
running off the end of the frame chain, assuming that we have usable
debugging information in the startup modules, and if we choose to not
use the block at main, or can't find it for some reason, everything
still works as before. And if we have no startup code debugging
information but we do have usable information for main(), backtraces
from user code don't go wandering off into the startup code.
To use this method, define your FRAME_CHAIN_VALID macro like:
#define FRAME_CHAIN_VALID(chain, thisframe) \
(chain != 0 \
&& !(inside_main_func ((thisframe)->pc)) \
&& !(inside_entry_func ((thisframe)->pc)))
and add initializations of the four scope controlling variables inside
the object file / debugging information processing modules. */

Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com> Except for the two m32r modules, this checkin is for overlay support. * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(), find_pc_sect_function(), find_pc_sect_partial_function(): new functions for debugging overlays; pc without section is ambiguous. * breakpoint.[ch]: add section pointer to breakpoint struct; add section argument to check_duplicates(); check section as well as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(), breakpoint_thread_match(), bpstat_stop_status()]; add section argument to describe_other_breakpoints(); use INIT_SAL() macro to zero-out new sal structures; make resolve_sal_pc() fix up the sal's section as well as its pc; match on section + pc in clear_command() and delete_breakpoint(); account for overlay sections in insert_breakpoints(), remove_breakpoint() and breakpoint_re_set_one(); all this to support overlays where a PC is not unique. * exec.c: change xfer_memory() to handle overlay sections. * findvar.c: change read_var_value() to handle overlay sections. * frame.h: declaration for block_for_pc_sect() [blockframe.c]. * infcmd.c: jump_command() warns against jumping into an overlay that's not in memory. Also use INIT_SAL() to initialize sals. * infrun.c: wait_for_inferior() sets a flag to invalidate cached overlay state information; Also use INIT_SAL() to init sals. * m32r-rom.c: modify load routines to use LMA instead of VMA. * m32r-stub.c: mask exit value down to 8 bits; screen out any memory read/writes in the range 600000 to a00000, and ff680000 to ff800000 (hangs because nothing is mapped there); fix strcpy(). * maint.c: maintenance command "translate-address" supports overlays. * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays. * objfiles.[ch]: add ovly_mapped field to the obj_section struct; this constitutes gdb's internal overlay mapping table. Add macro ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays. Add function find_pc_sect_section(). * printcmd.c: modify print_address_symbolic() with overlay smarts; modify address_info() with overlay smarts; add function sym_info() to support the INFO SYMBOL command (translate address to symbol(s)); modify disassemble_command() to work on unmapped overlays. * source.c: use INIT_SAL() to initialize sals. * symfile.[ch]: change generic_load() to use section's LMA address instead of VMA address, for overlay sections. Add numerous functions for finding a PC's section / overlay, translating between VMA and LMA address ranges, determining if an overlay section is mapped, etc. Add several user commands for overlay debugging. Add support for a "generic" form of automatically reading overlay mapping info from the inferior (based on the default (simple) overlay manager which Cygnus provides as an example). * symtab.[ch]: add functions find_pc_sect_symtab(), find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line() for lookup; modify lookup_symbol and decode_line_1() to use them; modify find_function_start_sal() to account for overlay sections; add macro INIT_SAL() for initializing struct symtab_and_line. * target.c: fix a comment in the declaration of target_ops.

Add support for a "generic" form of automatically reading overlay mapping info from the inferior (based on the default (simple) overlay manager which Cygnus provides as an example). * symtab.[ch]: add functions find_pc_sect_symtab(), find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line() for lookup; modify lookup_symbol and decode_line_1() to use them; modify find_function_start_sal() to account for overlay sections; add macro INIT_SAL() for initializing struct symtab_and_line. * target.c: fix a comment in the declaration of target_ops.

Thu Apr 3 15:10:30 1997 Michael Snyder <msnyder@cleaver.cygnus.com> Except for the two m32r modules, this checkin is for overlay support. * blockframe.c: blockvector_for_pc_sect(), block_for_pc_sect(), find_pc_sect_function(), find_pc_sect_partial_function(): new functions for debugging overlays; pc without section is ambiguous. * breakpoint.[ch]: add section pointer to breakpoint struct; add section argument to check_duplicates(); check section as well as pc in [breakpoint_here_p(), breakpoint_inserted_here_p(), breakpoint_thread_match(), bpstat_stop_status()]; add section argument to describe_other_breakpoints(); use INIT_SAL() macro to zero-out new sal structures; make resolve_sal_pc() fix up the sal's section as well as its pc; match on section + pc in clear_command() and delete_breakpoint(); account for overlay sections in insert_breakpoints(), remove_breakpoint() and breakpoint_re_set_one(); all this to support overlays where a PC is not unique. * exec.c: change xfer_memory() to handle overlay sections. * findvar.c: change read_var_value() to handle overlay sections. * frame.h: declaration for block_for_pc_sect() [blockframe.c]. * infcmd.c: jump_command() warns against jumping into an overlay that's not in memory. Also use INIT_SAL() to initialize sals. * infrun.c: wait_for_inferior() sets a flag to invalidate cached overlay state information; Also use INIT_SAL() to init sals. * m32r-rom.c: modify load routines to use LMA instead of VMA. * m32r-stub.c: mask exit value down to 8 bits; screen out any memory read/writes in the range 600000 to a00000, and ff680000 to ff800000 (hangs because nothing is mapped there); fix strcpy(). * maint.c: maintenance command "translate-address" supports overlays. * minsyms.c: lookup_minimal_symbol_by_pc_sect() supports overlays. * objfiles.[ch]: add ovly_mapped field to the obj_section struct; this constitutes gdb's internal overlay mapping table. Add macro ALL_OBJSECTIONS() to loop thru the obj_structs and look at overlays. Add function find_pc_sect_section(). * printcmd.c: modify print_address_symbolic() with overlay smarts; modify address_info() with overlay smarts; add function sym_info() to support the INFO SYMBOL command (translate address to symbol(s)); modify disassemble_command() to work on unmapped overlays. * source.c: use INIT_SAL() to initialize sals. * symfile.[ch]: change generic_load() to use section's LMA address instead of VMA address, for overlay sections. Add numerous functions for finding a PC's section / overlay, translating between VMA and LMA address ranges, determining if an overlay section is mapped, etc. Add several user commands for overlay debugging. Add support for a "generic" form of automatically reading overlay mapping info from the inferior (based on the default (simple) overlay manager which Cygnus provides as an example). * symtab.[ch]: add functions find_pc_sect_symtab(), find_pc_sect_psymtab(), find_pc_sect_psymbol(), find_pc_sect_line() for lookup; modify lookup_symbol and decode_line_1() to use them; modify find_function_start_sal() to account for overlay sections; add macro INIT_SAL() for initializing struct symtab_and_line. * target.c: fix a comment in the declaration of target_ops.
