System: NetBSD polaris 1.3 NetBSD 1.3 (POLARIS) #0: Thu Mar 26 13:17:18 MST 1998 root@polaris:/usr/src/sys/arch/i386/compile/POLARIS i386


>Description:
Attempting to create a -R or -rpath string that can be given to a.out
platforms as a nop uncovered this little gem:

legend:  rigel= alpha with snapshot -current toolchain
       polaris= i386 with 1.3

[/home/garbled] polaris# ctest
+ cc -Wl,-rpath,/usr/pkg/lib test.c
ld: /usr/pkg/lib: malformed input file (not rel or archive)
+ cc -rpath /usr/pkg/lib test.c
ld: /usr/pkg/lib: malformed input file (not rel or archive)
+ cc -R /usr/pkg/lib test.c
+ cc -R/usr/pkg/lib test.c

rigel# ./ctest
+ cc -Wl,-rpath,/usr/pkg/lib test.c
+ cc -rpath /usr/pkg/lib test.c
+ cc -R /usr/pkg/lib test.c
cc: unrecognized option `-R'
/usr/pkg/lib: file not recognized: File format not recognized
+ cc -R/usr/pkg/lib test.c
cc: unrecognized option `-R/usr/pkg/lib'

Also note:  the -R option, while it generates an error and does not perform
a proper link, does *not* give a failure exit status, and creates the
useless binary.  This means that big make files just keep on chugging
even though they are generating garbage binaries. (and pkgs!)

	
>How-To-Repeat:
for any test.c:
#!/bin/sh -x
cc -Wl,-rpath,/usr/pkg/lib test.c
cc -rpath /usr/pkg/lib test.c
cc -R /usr/pkg/lib test.c
cc -R/usr/pkg/lib test.c

	
>Fix:
Make the options consistent..  First off, -R should work on alpha..  second,
-rpath shouldn't generate wild ld warnings and fail the build on a.out.
And some checking should be done to make sure cc uses EXIT_FAILURE if it blows
up on an unknown option.
