Minimal symbols, partial symbols, and partial symtabs all use
unrelocated addresses right now. This series converts these to use
the unrelocated_addr type, revealing (I believe) a few latent bugs.
Regression tested on x86-64 Fedora 36.

Tom Tromey (6):
Use function_view in gdb_bfd_lookup_symbol
Move definition of unrelocated_addr earlier
Use unrelocated_addr in partial symbol tables
Use unrelocated_addr in psymbols
Use unrelocated_addr in minimal symbols
Rename "raw" to "unrelocated"

This changes gdb_bfd_lookup_symbol to use a function_view. This
simplifies the code a little bit.

This moves the definition of unrelocated_addr a bit earlier in
symtab.h, so that it can be used elsewhere in the file.

This changes partial symbol tables to use unrelocated_addr for the
text_high and text_low members. This revealed some latent bugs in
ctfread.c, which are fixed here.

From: Tom Tromey @ 2023-03-21 19:18 UTC (permalink / raw)
To: gdb-patches
Per an earlier discussion, this patch renames the existing "raw" APIs
to use the word "unrelocated" instead.

You fixed "Return NULL" to "Return 0" in the doc for the other function.
You could do it for the documentation of
bfd_lookup_symbol_from_dyn_symtab as well.
Otherwise, LGTM.

Given the time I have right now, I just looked at a subset of the
changes, it looks fine to me.
On thought I had is that the frob_address function (from minsyms.c)
would be a good candidate to become a general-purpose
objfile::unrelocate method (for those callers that don't know the
section index).

This caused a regression on aarch64-linux. Previously
gdb.asm/asm-source.exp passed all tests, but now:

The failures happen because GDB isn't able to step into foo2 anymore,
and steps over it instead:
(gdb) PASS: gdb.asm/asm-source.exp: next over macro
s^M
53 gdbasm_exit0^M
(gdb) FAIL: gdb.asm/asm-source.exp: step into foo2
I'm currently investigating.
