From: Keith Seitz Date: Fri, 10 Aug 2018 17:43:17 +0000 (-0700) Subject: Move C-related declarations to compile-c.h X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b7dc48b4a8006abb552c5e7d22f9841c86f2537d;p=binutils-gdb.git Move C-related declarations to compile-c.h This patch simply moves a bunch of C language-related declarations from the various compile header files into a new C-specific header, compile-c.h. gdb/ChangeLog: * Makefile.in (SUBDIR_GCC_COMPILE_SRCS): Move header files ... (HFILES_NO_SRCDIR): ... to here. Add compile-internal.h and compile-c.h. * compile/compile-c-support.c: Include compile-c.h. * compile/compile-c-symbols.c: Include compile-c.h. (generate_c_for_variable_locations): Update comment. * compile/compile-c-types.c: Include compile-c.h. * compile/compile-c.h: New file -- moved C language declarations from other files here. * compile/compile-internal.h: Do not include hashtab.h or common/enum-flags.h. (gcc_qualifiers_flags, struct compile_c_instance, C_CTX) (gcc_convert_symbol, gcc_symbol_address) (generate_c_for_variable_locations, c_get_mode_for_size) (c_get_range_decl_name): Definitions moved to compile-c.h. * compile/compile-loc2c.c: Include compile-c.h. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index a42e801ab59..c2a3a26a844 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,22 @@ +2018-08-10 Keith Seitz + + * Makefile.in (SUBDIR_GCC_COMPILE_SRCS): Move header files ... + (HFILES_NO_SRCDIR): ... to here. + Add compile-internal.h and compile-c.h. + * compile/compile-c-support.c: Include compile-c.h. + * compile/compile-c-symbols.c: Include compile-c.h. + (generate_c_for_variable_locations): Update comment. + * compile/compile-c-types.c: Include compile-c.h. + * compile/compile-c.h: New file -- moved C language declarations + from other files here. + * compile/compile-internal.h: Do not include hashtab.h or + common/enum-flags.h. + (gcc_qualifiers_flags, struct compile_c_instance, C_CTX) + (gcc_convert_symbol, gcc_symbol_address) + (generate_c_for_variable_locations, c_get_mode_for_size) + (c_get_range_decl_name): Definitions moved to compile-c.h. + * compile/compile-loc2c.c: Include compile-c.h. + 2018-08-10 Keith Seitz * compile/compile-c-symbols.c (symbol_substitution_name): Rename to ... diff --git a/gdb/Makefile.in b/gdb/Makefile.in index c007fbc0008..f9d1b007022 100644 --- a/gdb/Makefile.in +++ b/gdb/Makefile.in @@ -319,9 +319,7 @@ SUBDIR_GCC_COMPILE_SRCS = \ compile/compile-c-types.c \ compile/compile-loc2c.c \ compile/compile-object-load.c \ - compile/compile-object-load.h \ - compile/compile-object-run.c \ - compile/compile-object-run.h + compile/compile-object-run.c SUBDIR_GCC_COMPILE_OBS = $(patsubst %.c,%.o,$(filter %.c,$(SUBDIR_GCC_COMPILE_SRCS))) @@ -1462,6 +1460,10 @@ HFILES_NO_SRCDIR = \ common/x86-xstate.h \ common/xml-utils.h \ compile/compile.h \ + compile/compile-c.h \ + compile/compile-internal.h \ + compile/compile-object-load.h \ + compile/compile-object-run.h \ config/nm-linux.h \ config/nm-nto.h \ config/djgpp/langinfo.h \ diff --git a/gdb/compile/compile-c-support.c b/gdb/compile/compile-c-support.c index 696bb9fced9..41fead9ad19 100644 --- a/gdb/compile/compile-c-support.c +++ b/gdb/compile/compile-c-support.c @@ -19,6 +19,7 @@ #include "defs.h" #include "compile-internal.h" +#include "compile-c.h" #include "compile.h" #include "gdb-dlfcn.h" #include "c-lang.h" diff --git a/gdb/compile/compile-c-symbols.c b/gdb/compile/compile-c-symbols.c index 9364fc27ac5..c82e0086598 100644 --- a/gdb/compile/compile-c-symbols.c +++ b/gdb/compile/compile-c-symbols.c @@ -20,6 +20,7 @@ #include "defs.h" #include "compile-internal.h" +#include "compile-c.h" #include "symtab.h" #include "parser-defs.h" #include "block.h" @@ -706,7 +707,7 @@ generate_c_for_for_one_variable (struct compile_c_instance *compiler, END_CATCH } -/* See compile-internal.h. */ +/* See compile-c.h. */ gdb::unique_xmalloc_ptr generate_c_for_variable_locations (struct compile_c_instance *compiler, diff --git a/gdb/compile/compile-c-types.c b/gdb/compile/compile-c-types.c index 212cfe66bef..46b9f2b3b42 100644 --- a/gdb/compile/compile-c-types.c +++ b/gdb/compile/compile-c-types.c @@ -21,6 +21,7 @@ #include "defs.h" #include "gdbtypes.h" #include "compile-internal.h" +#include "compile-c.h" #include "objfiles.h" /* An object that maps a gdb type to a gcc type. */ diff --git a/gdb/compile/compile-c.h b/gdb/compile/compile-c.h new file mode 100644 index 00000000000..cff2aef906e --- /dev/null +++ b/gdb/compile/compile-c.h @@ -0,0 +1,81 @@ +/* Header file for GDB compile C-language support. + Copyright (C) 2014-2018 Free Software Foundation, Inc. + + 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.
