A68k on 64 bits plateforms - Page 1

I get these bugs of compilation, on my Fedora 11 x86_64 :

PedroM.asm line 36
 1895           moveq   #$FFFFFFFF,d7                   ; ARC_ST_OID
                        ^ Operand size error.

It works fine if I replace that with negative values (#-1, #-2).

I don't know enough C and 64 bits specificities to suggest a patch... sorry ...

I've never looked at the A68k sources... PpHd ?

Please post a ticket on the Trac, so that this does not fall into oblivion

Ok.

Something has been done on this?

Not yet.

The following one-liner, which forces sign extension, fixes this particular problem for me:

diff --git a/trunk/external/a68k/source/Codegen.c b/trunk/external/a68k/source/Codegen.c

Your patch works

btw -> GCC4TI installs and runs fine under Fedora 12 64 bits

ps -> do you the list of all warnings I've got when compiling ?

Thanks for the reports (that the patch works and that GCC4TI's build scripts work for F12 x86_64)

ps -> do you want the list of all warnings I've got when compiling ?

Of course, at least those affecting other programs than binutils and GCC
