linker argument order
Hi,
there's a quirk in the Sun Studio 12 RC version you distributed at LinuxTag 2007
in Berlin, Germany (Александр Горшенев told me to report any more bugs I find
to this forum).
begin pastetg@odem:~ $ $SP/bin/cc -# -Wl,-dynamic-linker,/usr/libexec/ld.so hello.c

As you can see, the argument "-dynamic-linker /lib/ld-linux.so.2" overrides the one I
give it on the command line, instead of vice versa (i.e. the other way round).
Also, where is that -Y argument generated from?
Ideally, I would use something like “-Wl,-dynamic-linker,/usr/libexec/ld.so -Wl,-Y,/usr/lib”
to create binaries (for BSD, not for Linux – it works, I just have to create a wrapper around
ld as described in http://marc.info/?m=118099390924175 and in mails to Alexander).
So it'd be nice if the options given on the command line via -Wl (etc.) are appended to
all automatically generated flags, instead of prepended. I'm not quite sure about the
order of the arguments w.r.t the files – maybe the -Y and -Qy arguments should be moved
before the crti.o, and between them and crti.o place the user-given arguments.
Also, is there a kind of “spec file” like gcc or a command line option or whatever to tell
it to use different crt*.o files? At the moment, I'm using “ld -r” to combine our five into the
three the Sun compiler expects.
But still (despite bug 6565674) a great job you have done, thanks!
