[arnm-elf-objdump] Can't use two -M flags for disassembler (-Mforce-thumb and -Mreg-names-raw)

[Vincent Rubiolo]

Hello Nick,

Thanks for your reply.

Investigating a little more, this seems to happen even with ARM-only/THUMB_only 
code: the disassembler turns off -Mforce-thumb option when used with 
-Mreg-names-raw for an ADS object file, either ARM or THUMB code.

You will find enclosed four files:
1. Hello.c is the source of an Hello World program (in case you need it)
2. Hello-THUMB.o is output of tcc, the ADS THUMB C compiler
3. Hello-ARM.o is the output of armcc, the ADS ARM C compiler (so you may 
compare if needed)
4. The different commands issued to spot the problem

Note: To decrease the size of the object files, I disabled linking.
Let me tell you if there are other things you may find useful.

Thank you very much for your consideration.

Best regards,

Vincent

PS: I will only be back on Tuesday so I will not be able to reply before
