on some revised hardware manuals of V850Ex/xxx controllers a hardware conflict in conjunction with the SLD instruction and Interrupt requests are described.
For example: V850E/ME2, August 2005, p113, 3.4.11 Restriction on conflict between sld instruction and interrupt request http://www.necel.com/nesdis/image/U16031EJ4V1UD00.pdf V850ES/HG2, December 2005, p75 , (3) Restriction on conflict between sld instruction and interrupt request http://www.necel.com/nesdis/image/U17718EJ1V0UD00.pdf The NEC CA850 V2.61 C-Compiler and IAR C-Compiler for V850 V3.20A compensate this hardware problem. Does the current Gnu C-Compiler for V850E also compensate this problem ?
