From 6f88f0312286a7356b43ff479642a4894ea07890 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Thu, 16 Jun 1994 21:59:41 +0000 Subject: [PATCH] * configure.in: Set UNDERSCORE in Makefile based on result of invoking config.bfd with a second argument of ``_''. * Makefile.in (underscore.c): Depend upon Makefile. Don't try to run $(CC) and $(NM), just use $(UNDERSCORE). Create via temporary file. (demangle.o): Remove target. ($(NM_PROG)): Don't depend upon demangle.o, and don't link against demangle.o. It's in libiberty anyhow. (cplus-dem.o): Don't depend upon demangle.o. * binutils.texi: Mention -n and --no-strip-underscores arguments to c++filt. --- binutils/ChangeLog | 17 +++++++++++++++++ binutils/Makefile.in | 25 +++++++------------------ binutils/binutils.texi | 8 +++++++- binutils/configure.in | 7 +++++++ 4 files changed, 38 insertions(+), 19 deletions(-) diff --git a/binutils/ChangeLog b/binutils/ChangeLog index 7c020049528..a61c689651f 100644 --- a/binutils/ChangeLog +++ b/binutils/ChangeLog @@ -1,3 +1,17 @@ +Thu Jun 16 17:25:20 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com) + + * configure.in: Set UNDERSCORE in Makefile based on result of + invoking config.bfd with a second argument of ``_''. + * Makefile.in (underscore.c): Depend upon Makefile.
