add short-circuit logic to elfread.c
If minimal symbols have already been read into a per-BFD object, then
a symbol reader can skip re-reading them. This changes the ELF reader
to do so.
We only skip the work if the file is ELF+DWARF. If it has stabs or
mdebug sections, then I think extra information is computed during the
minsym creation pass; and so we must still repeat it. Eventually even
this will go away, once all symbol types have switched to being
progspace-independent. In the meantime this has no negative effect --
it is just a missing optimization for a small set of users.
This change also required a somewhat non-obvious change to the OBJSTAT
accounting code. If a symbol reader skips re-reading minimal symbols,
then the corresponding OBJSTAT will not be updated. This leads to a
test failure in gdb.base/maint.exp.
After looking at a few fixes for this minor problem, I decided to just
remove minimal symbols from OBJSTATS. This seemed best to me first
because it eliminates duplicate accounting, and second because the
OBJSTATS were historically wrong here -- including minsyms that were
deleted by de-duplication.
* elfread.c (elf_read_minimal_symbols): Return early if
minimal symbols have already been read. Add "ei" parameter.
(elf_symfile_read): Call elf_read_minimal_symbols earlier.
* minsyms.c (prim_record_minimal_symbol_full): Update.
* objfiles.h (struct objstats) <n_minsyms>: Remove.
* symmisc.c (print_objfile_statistics): Update.

split out elf_read_minimal_symbols
This is just a simple refactoring in elfread.c to split out the
minsym-reading code into its own function.
* elfread.c (elf_read_minimal_symbols): New function, from
elf_symfile_read.
(elf_symfile_read): Call it.

move minimal symbols to per-bfd
Now that minimal symbols are independent of the program space, we can
move them to the per-BFD object. This lets us save memory in the
multi-inferior case; and, once the symbol readers are updated, time.
The other prerequisite for this move is that all the objects referred
to by the minimal symbols have a lifetime at least as long as the
per-BFD object. I think this is satisfied partially by this patch
(moving the copied names there) and partially by earlier patches
moving the demangled name hash.
This patch contains a bit of logic to avoid creating new minimal
symbols if they have already been read for a given BFD. This allows
us to avoid trying to update all the symbol readers for this
condition. At first glance this may seem like a hack, but some symbol
readers mix psym and minsym reading, and would require logic just like
this regardless -- and it is simpler and less error-prone to just do
the work in a central spot.

change minsyms not to be relocated at read-time
This removes the runtime offsets from minsyms. Instead, these offsets
will now be applied whenever the minsym's address is computed.
This patch redefines MSYMBOL_VALUE_ADDRESS to actually use the offsets
from the given objfile. Then, it updates all the symbol readers,
changing them so that they do not add in the section offset when
creating the symbol.
This change also lets us remove relocation of minsyms from

start change to progspace independence
This patch starts changing minimal symbols to be independent of the
program space.
Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS
and changes all the code to use it. This is needed so we can change
gdb to apply the section offset when a minsym's address is computed,
as opposed to baking the offsets into the symbol itself.
A few spots still need the unrelocated address. For these, we
introduce MSYMBOL_VALUE_RAW_ADDRESS.
As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS,
which computes the address of a bound minimal symbol. This just does
the obvious thing with the fields.
Note that this change does not actually enable program space
independence. That requires more changes to gdb. However, to ensure
that these changes compile properly, this patch does add the needed
section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has
no effect at runtime by multiplying the offset by 0.

use bound_minsym as result for lookup_minimal_symbol et al
This patch changes a few minimal symbol lookup functions to return a
bound_minimal_symbol rather than a pointer to the minsym. This change
helps prepare gdb for computing a minimal symbol's address at the
point of use.
Note that this changes even those functions that ostensibly search a
single objfile. That was necessary because, in fact, those functions
can search an objfile and its separate debug objfiles; and it is
important for the caller to know in which objfile the minimal symbol
was actually found.
The bulk of this patch is mechanical.

change minsym representation
In a later patch we're going to change the minimal symbol address
calculation to apply section offsets at the point of use. To make it
simpler to catch potential problem spots, this patch changes the
representation of minimal symbols and introduces new
minimal-symbol-specific variants of the various accessors. This is
necessary because it would be excessively ambitious to try to convert
all the symbol types at once.
The core of this change is just renaming a field in minimal_symbol;
the rest is just a fairly mechanical rewording.

introduce minimal_symbol_upper_bound
This introduces minimal_symbol_upper_bound and changes various bits of
code to use it. Since this function is intimately tied to the
implementation of minimal symbol tables, I believe it belongs in
minsyms.c.
The new function is extracted from find_pc_partial_function_gnu_ifunc.
This isn't a "clean" move because the old function interleaved the
caching and the computation; but this doesn't make sense for the new
code.
* blockframe.c (find_pc_partial_function_gnu_ifunc): Use
bound minimal symbols. Move code that knows about minsym
table layout...
* minsyms.c (minimal_symbol_upper_bound): ... here. New
function.
* minsyms.h (minimal_symbol_upper_bound): Declare.
* objc-lang.c (find_objc_msgsend): Use bound minimal symbols,

undef reg in gdb_curses.h
I tried to build gdb on the AIX machine in the GCC compile farm
(gcc111), but it failed in a couple of spots because gdb uses "reg" as
a variable name and the AIX <curses.h> defines "reg" to "register".
I saw that we already had a workaround for this lurking in utils.c, so
I just moved that to gdb_curses.h.
This fixed the problem on AIX and still builds on x86-64 Fedora 18.
* utils.c (reg): Move undefinition...
* gdb_curses.h: ... here. Update comment to mention AIX.

There were two functions who were calling "sizeof" twice.
The first one, dw2_get_real_path from gdb/dwarf2read.c, was actually
making use of OBSTACK_CALLOC which already calls "sizeof" for its third
argument.
The second, download_tracepoint_1 from gdb/gdbserver/tracepoint.c, was
explicitly calling "sizeof" inside another "sizeof".
This patch fixed both functions.

This is a simple bug. target_disable_btrace and target_teardown_btrace,
both from gdb/target.c, do a "return" calling another function. But both
are marked as void. Despite the fact that the functions being called are
void as well, this is wrong. This patch fixes this by calling the functions
and then returning in the next line.
