So, the situation is like this:
1) Target ARM architecture needs to be "told" to FPC since FPC needs
this information to do correct code generation.
2) FPC does not inform GNU assembler of intended ARM architecture for
which assembler code is generated for, which doesn't prevent GNU as
from gener

If you want to know more about what code the compiler produces there are
two more opportunities:
First you can tell the compiler to not delete the intermediate asse

Sorry to everyone for replying so far down the thread to the points
mentioned earlier.
The FPC ARM support is stated as ' does not specify an ARM architecture' ...
fine ..but there is a major issue there that needs clarification and better
documentation.
Is it really safe to have no way to target

I'd wondered about THUMB support. That means no STM-32 processors, as
THUMB code is all they execute. Bummer, as they are nice and extre

My point is saying 'guess' was not to discredit your statement about what
the FP compiler does, rather to say that no one seems to know exactly what
ARM option FP sends to the GNU Assembler and what that option value actually
is.
Reading the GNU as manual, the arch parameter value needs to be set

Thank you for that reply.
OK.. well if that opinion is just a guess, then as this is really a question
that has to be answered by actually looking at the FP code and finding out
what it sets as the ARM specific GNU AS command line options.
