[Mspgcc-users] Bug in code generation

[Daniel Sch�rmann]

Hello,

i might have found a problem with code generation and optimization.
.

I use the command:
msp430-gcc -mmcu=msp430x1132 -g -O2 -Wall   -c -o Merten_Argus.o Merten_Argus.c

This shows insight im mixed View:
 <<MA_get_brigtness.mix>> 
Here are the *.i and *.s files:
 <<Merten_Argus.i>>  <<Merten_Argus.s>> 
In Funktion MA_get_brightness, the statement:

buff *= im_SegA.im.MA_gain_multipier;  

is not compiled correctly. But when I delete the irrelevant line

buff  = (U32)(MA_brightness & 0x07ff );

or switch off the optimization, everything works as desired.

I have already made a workaround for my problem, but maybe my report helps to 
improve mspgcc.


Kind regards

Daniel Schürmann
