This gives linker error when rand() is used from newlib. This problem should be there for other targets where sizeof( long long ) is not more than 32. >How-To-Repeat: Compile code below with h8300-*-gcc -S and you will see a call to ___muldi3 void foo() { unsigned long long a ; a = a * 664136223846793005LL ; } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
