Re: [patch/in] Add (broken) hppa-elf target

PS: To give you a headache :-) Even though a native i386-ibm-aix won't
build, there is a good chance that an i386-ibm-aix host will build an
i386-ibm-aix cross debugger. This is correct behavour because a cross
debugger should be buildable on any host :-)
Yup. Except that --target=i386-ibm-aix won't give you exactly a
i386-ibm-aix cross-debuger. It will give you the same generic i386
cross-debuger as --target=i386-elf or --target=i386-whatever-junk.
Suppose i386-ibm-aix had a rather peculiar ABI that's really
incompatible with the generic i386 ABI. The resulting GDB would not
be very useful. Shouldn't we somehow warn against this?
(I've ended up debugging an arm target using an x86 gdb so it is still
useful :-)
I guess we could. src/configure.in currently disables the ia64-elf
target because it doesn't build. A warning message is printed but it is
burried in amongst all the other autoconf output.
Anyway, I think it is easier in cases such as this, to just let GDB
built the best it can. If a warning is really needed then perhaps have
the OS sniffer detect and report something (Hmm, I just deleted the
messaging indicating that the OSABI was unknown :-( ).
enjoy,
Andrew
