gas/config/tc-msp430.h defines NUMBERS_WITH_SUFFIX, so this is the
number 0 with trailing garbage (which isn't properly diagnosed).  Use
0101B instead.

Question about MSP430 assembler compiler

2014-10-31 Thread Eugene 
   The program code in assembly language:
   ...
Loop:  xor.b  #0b0101,&P1OUT
   call   #Wait
   jmpLoop
   ...

   After compilation, see:
Loop:  xor.b  #0b0101,&P1OUT
c018:   c2 e3 21 00 xor.b   #0, &0x0021 ;r3 As==00

c01c <.Loc.16.1>:
   call   #Wait
c01c:   b0 12 22 c0 call#49186  ;#0xc022

c020 <.Loc.17.1>:
   jmpLoop
c020:   fb 3f   jmp $-8 ;abs 0xc018

Question: why on the label 'Loop' occurred loading #0 instead of #0x41?

Thanks.
