Say we're debugging a test-case with CUs with name "<artificial>", meaning
not originating from a single file compilation, and use the verbose setting:
...
$ gdb -iex "set verbose on" -batch cc1
Reading symbols from cc1...
Reading in symbols for <artificial>... \
and /tmp/trunk/gcc/attribs.c... \
...
and /tmp/trunk/gcc/tree-ssa-reassoc.c... \
done.
...
From the "/tmp/trunk/gcc/attribs.c" message, it's clear which CU is loaded. But
that's not the case for the "<artificial>" message.
The message uses the filename field of struct partial_symtab, which is
documented like this:
...
/* Name of the source file which this partial_symtab defines,
or if the psymtab is anonymous then a descriptive name for
debugging purposes, or "". It must not be NULL. */
...
So, fix this by setting the filename field to a more descriptive name than
"<artificial>", by appending the CU offset.
This way, we print instead:
...
$ gdb -iex "set verbose on" -batch cc1
Reading symbols from cc1...
Reading in symbols for <artificial>@0x41146d9 \
and /tmp/trunk/gcc/attribs.c... \
... \
and /tmp/trunk/gcc/tree-ssa-reassoc.c... \
done.
...

cutu_reader has a "keep" parameter, which is used to decide what to do

This changes the "want_partial_unit" parameters to have type bool, and
also removes the parameter from process_psymtab_comp_unit_reader.

a partial unit.

htab_up. This just removes a bit of manual management.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/read.c (~dwarf2_per_objfile): Update.
(create_quick_file_names_table): Return htab_up.
(dw2_get_file_names_reader, dw2_forget_cached_source_info):
Update.

abbrev_table::read increments cur_abbrev->num_attrs in the inner loop,
but there's no need to do this, as the information is already stored
in the temporary vector.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/abbrev.c (abbrev_table::read): Simplify.
Change-Id: I765f12850ffa1c6066e884bb22c94468d1abdba4
This changes abbrev_table to use an htab_up rather than an ad hoc,
bucket-based hash table.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/abbrev.c (abbrev_table): Move constructor from header.
Rewrite.

Change-Id: Icbaa8e49501f9c43218d6a81a7e8c4d3a77d65dc
This cleans up the DWARF abbrev_table API a bit, primarily by making
various methods and members private.

This changes dwarf2_per_objfile::die_type_hash to be an htab_up,
moving its contents off the objfile obstack.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/read.c (set_die_type, get_die_type_at_offset): Update.

htab_up.
Change-Id: Ic651f99ebf71bf7ad2dc2880192adacf7b60964a
This changes dwp_file to use htab_up for the loaded_cus and loaded_tus
members. This lets us avoid allocating the contents of these hash
tables on the objfile obstack.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/read.c (struct dwp_file) <loaded_cus, loaded_tus>: Now
htab_up.
(lookup_dwo_unit_in_dwp): Update.
(allocate_dwp_loaded_cutus_table): Return htab_up. Don't allocate
on obstack.
Change-Id: Id61209bf5c6c6faa0c067195af31fbcf26813a3a
This changes allocate_dwo_file_hash_table so that it does not use the
objfile obstack to store the contents of the hash table.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/read.c (allocate_dwo_file_hash_table): Don't allocate on
obstack.
Change-Id: Ic20a618acc7277e56aa18580c68f75c793bef97b
This changes dwarf2_per_objfile::line_header_hash to be an htab_up,
and changes it to use heap allocation.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/read.c (~dwarf2_per_objfile): Don't delete
line_header_hash.
(handle_DW_AT_stmt_list): Update. Don't allocate on obstack.
* dwarf2/read.h (struct dwarf2_per_objfile) <line_header_hash>:
Change type to htab_up.
Change-Id: Icb148a270838c0f96f38fc4a28b5b77d067927b6
This changes dwarf2_per_objfile::type_unit_groups to be an htab_up,
again allowing us to move the memory used by the hash table from the
objfile obstack to the heap.
2020-02-08 Tom Tromey <tom@tromey.com>
* dwarf2/read.c (allocate_type_unit_groups_table): Return
htab_up. Don't allocate on obstack.
(get_type_unit_group, dwarf2_build_psymtabs_hard): Update.
* dwarf2/read.h (struct dwarf2_per_objfile) <type_unit_groups>:
Change type to htab_up.
Change-Id: Ia045df0ff3ec30aac813da5a9a2314a607ef7ec8
This changes dwarf2_per_objfile::signatured_types to be an htab_up.
This in turn lets us change it not to use the objfile obstack for
allocation; obstack allocation for hash tables is a bad practice
because it leads to excess memory use if the table is ever resized.

This removes some queue-related globals from the DWARF reader, in
favor of a new member on dwarf2_per_objfile. Globals must be avoided
in this code, because they prevent multi-threading the reader.

2020-02-08 Tom Tromey <tom@tromey.com>

Many functions take a "has_children" parameter (either as an in- or
out-parameter). However, it seems to me that it makes more sense to
have "has_children" be an attribute of a DIE. Making this change
allows this parameter to be eliminated in many places.

This changes attr_form_is_block to be a method. This is done
separately because, unlike the other attribute functions,
attr_form_is_block had special handling for the case where the
argument was NULL. This required auditing each call site; in most
cases, NULL was already ruled out, but in a few spots, an additional
check was needed.
