[Bug c/35872] New: [4.1 regression] incorrect code for 32bit multiplication by constant

Tue, 08 Apr 2008 09:12:22 -0700 

A 32bit multiplication by a constant results in incorrect code when compiled
for some AVR models (probably those having a hardware multiplier).

Command:
  avr-gcc -mmcu=attiny25 -Os -S t1.c      (correct)
  avr-gcc -mmcu=atmega16 -Os -S t1.c      (incorrect)
