Compiler: ti-cgt-arm_18.12.1.LTS

Please show a few lines of assembly code that do not build.  Also show exactly how you invoke the arm compiler shell armcl.

Thanks and regards,

Thanks for your fast reply, here is the snapshots. 

Thank you.

Remove the option --silicon_version=4.  It says to build for the old ARM7 CPU architecture.  And it overrides the -mv7R4 that appears first.

That said, I still cannot reproduce the problem.  Whether I build with or without --silicon_version=4, I get a clean build.  Odd.

If you want to continue to pursue it ... Please attach the file try_assembly.asm to your next post.  So the forum will accept it, add the file extension .txt to it.

Thanks and regards,

I have tried to remove that option but the same errors appear. The most probable reason is the compiler version may have a problem.

Please find the attached file.

Thanks an advance.

ADDEQ R2,R4,R5		 	; If the Z flag is set make R2:=R4+R5
TEQS R4,#3 				; test R4 for equality with 3.
						; (The S is in fact redundant as the
						; assembler inserts it automatically.)
SUB R4,R5,R7,LSR R2 	; Logical right shift R7 by the number in
						; the bottom byte of R2, subtract result
						; from R5, and put the answer into R4.
MOV PC,R14 				; Return from subroutine.
MOVS PC,R14 			; Return from exception and restore CPSR
						; from SPSR_mode.

Hello George,

Yes that was the mistake, it builds normally now.

Thanks a lot for your help.
