Move DWARF index-related things to a separate fileusers/simark/split-dwarf2read
I want to add a DWARF index-related feature (automatically produce index
files when loading objfiles in GDB), but I don't want to add many
hundred lines to the already too big dwarf2read.c. I thought it would
be a logical split to move everything related to the DWARF index to its
own file.
I first tried to move everything that reads and writes DWARF indices to
a separate file, but found that the "read" part is a little bit
entangled with the rest of dwarf2read.c, so the line is hard to draw
about where to split. The write part is quite isolated though, so I
moved this part to a new file, dwarf-index-write.c. Some things are
necessary to both reading and writing indices, so I placed them in
dwarf-index-common.{c,h}. The idea would be to have a
dwarf-index-read.c eventually that would use it too (for now that code
is still in dwarf2read.c).
This required moving some things to a new dwarf2read.h header, so they
can be read by the code that writes the index.
The patch is big in number of lines, but it's all existing code being
moved around. The only changes are that some functions are not static
anymore, a declaration is added in a .h file, and therefore the comment
is moved there.
I built-tested it with a little and big endian target.
This patch is also available on the users/simark/split-dwarf2read
branch.
