From: Ian Lance Taylor Date: Mon, 8 Jan 1996 23:18:29 +0000 (+0000) Subject: * objcopy.c: Include budbg.h. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f5818d79ddec0f5cd55bf625e2e8602b09113947;p=binutils-gdb.git * objcopy.c: Include budbg.h. (convert_debugging): New static variable. (OPTION_DEBUGGING): Define. (copy_options): Add "debugging". (copy_usage): Mention --debugging. (is_strip_section): Skip debugging sections if convert_debugging. (setup_section, copy_section): Likewise. (filter_symbols): Skip debugging symbols if convert_debugging. (copy_object): If convert_debugging, read and write debugging information. (write_debugging_info): New static function. (copy_main): Handle --debugging. * Makefile.in (DEBUG_OBJS): New variable. ($(OBJCOPY_PROG)): Depend upon and link against $(DEBUG_OBJS). ($(STRIP_PROG)): Likewise. (OBJDUMP_OBJS): Remove variable. ($(OBJDUMP_PROG)): Use objdump.o $(DEBUG_OBJS) rather than $(OBJDUMP_OBJS). * binutils.texi, objcopy.1: Document --debugging. --- diff --git a/binutils/Makefile.in b/binutils/Makefile.in index 6801d562ab0..b261d67543d 100644 --- a/binutils/Makefile.in +++ b/binutils/Makefile.in @@ -144,6 +144,7 @@ GENERATED_CFILES = \ .c.o: $(CC) -c $(ALL_CFLAGS) $< +DEBUG_OBJS = rddbg.o debug.o stabs.o ieee.o prdbg.o # ## Random definitions # Hopefully all these may be flushed once we get configuration down pat. @@ -256,22 +257,20 @@ dvi: binutils.dvi $(SIZE_PROG): $(ADDL_LIBS) size.o $(BFD) $(CC) $(CFLAGS) $(LDFLAGS) -o $(SIZE_PROG) size.o $(ADDL_LIBS) $(EXTRALIBS) -$(OBJCOPY_PROG): $(ADDL_LIBS) objcopy.o not-strip.o $(BFD) - $(CC) $(CFLAGS) $(LDFLAGS) -o $(OBJCOPY_PROG) objcopy.o not-strip.o $(ADDL_LIBS) $(EXTRALIBS) +$(OBJCOPY_PROG): $(ADDL_LIBS) objcopy.o not-strip.o $(DEBUG_OBJS) $(BFD) + $(CC) $(CFLAGS) $(LDFLAGS) -o $(OBJCOPY_PROG) objcopy.o not-strip.o $(DEBUG_OBJS) $(ADDL_LIBS) $(EXTRALIBS) $(STRINGS_PROG): $(ADDL_LIBS) strings.o $(BFD) $(CC) $(CFLAGS) $(LDFLAGS) -o $(STRINGS_PROG) strings.o $(ADDL_LIBS) $(EXTRALIBS) -$(STRIP_PROG): $(ADDL_LIBS) objcopy.o is-strip.o $(BFD) - $(CC) $(CFLAGS) $(LDFLAGS) -o $(STRIP_PROG) objcopy.o is-strip.o $(ADDL_LIBS) $(EXTRALIBS) +$(STRIP_PROG): $(ADDL_LIBS) objcopy.o is-strip.o $(DEBUG_OBJS) $(BFD) + $(CC) $(CFLAGS) $(LDFLAGS) -o $(STRIP_PROG) objcopy.o is-strip.o $(DEBUG_OBJS) $(ADDL_LIBS) $(EXTRALIBS) $(NM_PROG): $(ADDL_LIBS) nm.o $(BFD) $(CC) $(CFLAGS) $(LDFLAGS) -o $(NM_PROG) nm.o $(ADDL_LIBS) $(EXTRALIBS) -OBJDUMP_OBJS = objdump.o rddbg.o debug.o stabs.o ieee.o prdbg.o - -$(OBJDUMP_PROG): $(ADDL_LIBS) $(OBJDUMP_OBJS) $(BFD) $(OPCODES) - $(CC) $(CFLAGS) $(LDFLAGS) -o $(OBJDUMP_PROG) $(OBJDUMP_OBJS) $(OPCODES) $(ADDL_LIBS) $(EXTRALIBS) +$(OBJDUMP_PROG): $(ADDL_LIBS) objdump.o $(DEBUG_OBJS) $(BFD) $(OPCODES) + $(CC) $(CFLAGS) $(LDFLAGS) -o $(OBJDUMP_PROG) objdump.o $(DEBUG_OBJS) $(OPCODES) $(ADDL_LIBS) $(EXTRALIBS) underscore.c: stamp-under ; @true diff --git a/binutils/binutils.texi b/binutils/binutils.texi index fbec8beace8..31df7f1644e 100644 --- a/binutils/binutils.texi +++ b/binutils/binutils.texi @@ -13,7 +13,7 @@ END-INFO-DIR-ENTRY @end ifinfo @ifinfo -Copyright @copyright{} 1991, 1992, 1993, 1994, 1995 Free Software Foundation, Inc. +Copyright @copyright{} 1991, 92, 93, 94, 95, 1996 Free Software Foundation, Inc.
