-DESCRIPTION
+ DESCRIPTION
- 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().

- 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.

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.

- For instance, if a section has been mapped then its contents

+ 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
(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
