Remove an ifdef. Add comment about -nostdlib vs. ELF ld. 1997-05-30 18:06:34 +04:00			`# $NetBSD: Makefile,v 1.18 1997/05/30 14:06:34 cjs Exp $`
Use the extra LDFLAGS if OBJDIR is defined. 1997-05-30 15:39:01 +04:00
Remove an ifdef. Add comment about -nostdlib vs. ELF ld. 1997-05-30 18:06:34 +04:00			`.include <bsd.own.mk> # for BUILDDIR`

Shrink ld.so by 12k. 1994-09-19 08:49:02 +04:00			`SRCS= mdprologue.S rtld.c malloc.c shlib.c etc.c md.c vfprintf.c`
Install the manual page. 1995-08-25 14:08:45 +04:00			`MAN= rtld.1`
Add -fno-function-cse to PICFLAGS. Without it, Very Bad Things happen when ld.so is compiled with gcc 2.7.2 on the m68k. From Niklas Hallqvist <niklas@appli.se> in PR #1557. (Thanks, Nik, for reminding me about this PR...) 1996-01-02 11:54:28 +03:00			`PICFLAG=-fpic -fno-function-cse`
Ld directory reorganization: - separate out the common files used by rtld ldd ld - move machine dependent files into arch - move ld in its own directory - factor out .PATH and CFLAGS common to all Makefiles 1997-04-16 20:49:28 +04:00			`CFLAGS+=$(PICFLAG) -DRTLD -DLIBC_SCCS`
Minor cleanup. 1993-12-10 08:10:22 +03:00			`ASFLAGS+=-k`
