From: Tom Tromey Date: Sat, 20 Mar 2021 23:23:40 +0000 (-0600) Subject: Introduce dwarf2/public.h X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=701823751bec1bbf2f1c96463994f894d33d2238;p=binutils-gdb.git Introduce dwarf2/public.h This moves some more DWARF code out of symfile.h and into a new header, dwarf2/public.h. This header is intended to describe the public API of the DWARF reader. gdb/ChangeLog 2021-03-20 Tom Tromey * coffread.c: Include dwarf2/public.h. * dwarf2/frame.c: Include dwarf2/public.h. * dwarf2/index-write.h: Include dwarf2/public.h, not symfile.h. * dwarf2/public.h: New file. * dwarf2/read.c: Include dwarf2/public.h. * elfread.c: Include dwarf2/public.h. * machoread.c: Include dwarf2/public.h. * symfile.h (dwarf2_has_info, enum dw_index_kind) (dwarf2_initialize_objfile, dwarf2_build_psymtabs) (dwarf2_build_frame_info): Move to dwarf2/public.h. * xcoffread.c: Include dwarf2/public.h. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 5509d39d101..b06b6d23b66 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,17 @@ +2021-03-20 Tom Tromey + + * coffread.c: Include dwarf2/public.h. + * dwarf2/frame.c: Include dwarf2/public.h. + * dwarf2/index-write.h: Include dwarf2/public.h, not symfile.h. + * dwarf2/public.h: New file. + * dwarf2/read.c: Include dwarf2/public.h. + * elfread.c: Include dwarf2/public.h. + * machoread.c: Include dwarf2/public.h. + * symfile.h (dwarf2_has_info, enum dw_index_kind) + (dwarf2_initialize_objfile, dwarf2_build_psymtabs) + (dwarf2_build_frame_info): Move to dwarf2/public.h. + * xcoffread.c: Include dwarf2/public.h. + 2021-03-20 Tom Tromey * symfile.h (enum dwarf2_section_enum) diff --git a/gdb/coffread.c b/gdb/coffread.c index 49a2485d38c..d15ba6593fc 100644 --- a/gdb/coffread.c +++ b/gdb/coffread.c @@ -36,6 +36,7 @@ #include "target.h" #include "block.h" #include "dictionary.h" +#include "dwarf2/public.h" #include "coff-pe-read.h" diff --git a/gdb/dwarf2/frame.c b/gdb/dwarf2/frame.c index 4d62b197d3a..f8612c96f27 100644 --- a/gdb/dwarf2/frame.c +++ b/gdb/dwarf2/frame.c @@ -37,6 +37,7 @@ #include "complaints.h" #include "dwarf2/frame.h" #include "dwarf2/read.h" +#include "dwarf2/public.h" #include "ax.h" #include "dwarf2/loc.h" #include "dwarf2/frame-tailcall.h" diff --git a/gdb/dwarf2/index-write.h b/gdb/dwarf2/index-write.h index 5f6761c91a7..27f1f03cd8b 100644 --- a/gdb/dwarf2/index-write.h +++ b/gdb/dwarf2/index-write.h @@ -20,8 +20,8 @@ #ifndef DWARF_INDEX_WRITE_H #define DWARF_INDEX_WRITE_H -#include "symfile.h" #include "dwarf2/read.h" +#include "dwarf2/public.h" /* Create index files for OBJFILE in the directory DIR. diff --git a/gdb/dwarf2/public.h b/gdb/dwarf2/public.h new file mode 100644 index 00000000000..d0182d4e673 --- /dev/null +++ b/gdb/dwarf2/public.h @@ -0,0 +1,46 @@ +/* Public API for gdb DWARF reader + + Copyright (C) 2021 Free Software Foundation, Inc. + + This file is part of GDB. + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
