WARNING
|
||||
|
||||
This is only a partial ELF implementation,
|
||||
incorporating only those parts that are
|
||||
required to get gdb up and running. It is
|
||||
expected that it will be expanded to a full
|
||||
ELF implementation at some future date.
|
||||
|
||||
Unimplemented stubs call abort() to ensure
|
||||
that they get proper attention if they are
|
||||
ever called. The stubs are here since
|
||||
this version was hacked from the COFF
|
||||
version, and thus they will probably
|
||||
go away or get expanded appropriately in a
|
||||
future version.

/* Problems and other issues to resolve.
|
||||
|
||||
(1) BFD expects there to be some fixed number of "sections" in
|
||||
the object file. I.E. there is a "section_count" variable in the
|
||||
bfd structure which contains the number of sections. However, ELF
|
||||
supports multiple "views" of a file. In particular, with current
|
||||
implementations, executable files typically have two tables, a
|
||||
program header table and a section header table, both of which
|
||||
partition the executable.
|
||||
|
||||
In ELF-speak, the "linking view" of the file uses the section header
|
||||
table to access "sections" within the file, and the "execution view"
|
||||
uses the program header table to access "segments" within the file.
|
||||
"Segments" typically may contain all the data from one or more
|
||||
"sections".
|
||||
|
||||
Note that the section header table is optional in ELF executables,
|
||||
but it is this information that is most useful to gdb. If the
|
||||
section header table is missing, then gdb should probably try
|
||||
to make do with the program header table. (FIXME)
