Introduce buildsym-legacy.h
This introduces a new header, buildsym-legacy.h, and changes all the symbol readers to use it. The idea is to put the function-based interface, that relies on the buildsym_compunit global, into a separate header. Then when a symbol reader is updated to use the new interface, it can simply not include buildsym-legacy.h, so it's easy to be sure that the new API is used everywhere. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * xcoffread.c: Include buildsym-legacy.h. * windows-nat.c: Include buildsym-legacy.h. * stabsread.c: Include buildsym-legacy.h. * mdebugread.c: Include buildsym-legacy.h. * buildsym-legacy.h: New file. * buildsym-legacy.c: New file, from buildsym.c. * go32-nat.c: Include buildsym-legacy.h. * dwarf2read.c: Include buildsym-legacy.h. * dbxread.c: Include buildsym-legacy.h. * cp-namespace.c: Include buildsym-legacy.h. * coffread.c: Include buildsym-legacy.h. * buildsym.h: Move some contents to buildsym-legacy.h. * buildsym.c: Include buildsym-legacy.h.

/* This module provides definitions used for creating and adding to
|
||||
the symbol table. These routines are called from various symbol-
|
||||
file-reading routines. This file holds the legacy API, which
|
||||
relies on a global variable to work properly. New or maintained
|
||||
symbol readers should use the builder API in buildsym.h.
|
||||
|
||||
The basic way this module is used is as follows:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = start_symtab (...);
|
||||
... read debug info ...
|
||||
cust = end_symtab (...);
|
||||
|
||||
The compunit symtab pointer ("cust") is returned from both start_symtab
|
||||
and end_symtab to simplify the debug info readers.
|
||||
|
||||
There are minor variations on this, e.g., dwarf2read.c splits end_symtab
|
||||
into two calls: end_symtab_get_static_block, end_symtab_from_static_block,
|
||||
but all debug info readers follow this basic flow.
|
||||
|
||||
Reading DWARF Type Units is another variation:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = start_symtab (...);
|
||||
... read debug info ...
|
||||
cust = end_expandable_symtab (...);
|
||||
|
||||
And then reading subsequent Type Units within the containing "Comp Unit"
|
||||
will use a second flow:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = restart_symtab (...);
|
||||
... read debug info ...
|
||||
cust = augment_type_symtab (...);
|
||||
|
||||
dbxread.c and xcoffread.c use another variation:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = start_symtab (...);
|
||||
... read debug info ...
|
||||
cust = end_symtab (...);
|
||||
... start_symtab + read + end_symtab repeated ...

||||

/* This module provides subroutines used for creating and adding to
|
||||
the symbol table. These routines are called from various symbol-
|
||||
file-reading routines.
|
||||
|
||||
Routines to support specific debugging information formats (stabs,
|
||||
DWARF, etc) belong somewhere else.
|
||||
|
||||
The basic way this module is used is as follows:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = start_symtab (...);
|
||||
... read debug info ...
|
||||
cust = end_symtab (...);
|
||||
|
||||
The compunit symtab pointer ("cust") is returned from both start_symtab
|
||||
and end_symtab to simplify the debug info readers.
|
||||
|
||||
There are minor variations on this, e.g., dwarf2read.c splits end_symtab
|
||||
into two calls: end_symtab_get_static_block, end_symtab_from_static_block,
|
||||
but all debug info readers follow this basic flow.
|
||||
|
||||
Reading DWARF Type Units is another variation:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = start_symtab (...);
|
||||
... read debug info ...
|
||||
cust = end_expandable_symtab (...);
|
||||
|
||||
And then reading subsequent Type Units within the containing "Comp Unit"
|
||||
will use a second flow:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = restart_symtab (...);
|
||||
... read debug info ...
|
||||
cust = augment_type_symtab (...);
|
||||
|
||||
dbxread.c and xcoffread.c use another variation:
|
||||
|
||||
scoped_free_pendings free_pending;
|
||||
cust = start_symtab (...);
|
||||
... read debug info ...
|
||||
cust = end_symtab (...);
|
||||
... start_symtab + read + end_symtab repeated ...
