IIRC the M in TDMI stands for "hardware > multiplier unit". Experiences with gcc showed me that the 32x32=64 mult > commands are not used in that case. Wikipedia also calls ARM7 ARMV3 arch, and only ARM7TDMI ARMV4. This could be the reason why. (and maybe the D and the I)

The trick is that if you give FPC that info, it can check both code generated and the assembler reader, and do the same AND provide a valid source line. IOW, I don't see a good reason to do this in the backend assembler, if it can be better done in the frontend. For the rare (e.g. FPC development related) cases, simply make a few scripts with systematic naming that call the assembler with the right params, and then select the desired one using -XP. IIRC the buildfaq has an example of this (for the -m params) _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
