/* This caused an ICE during register spilling when targeting thumb. There are 8 registers available for arithmetic operations (r0-r7) r7 is the frame pointer, and r0-r3 are used to pass arguments. Combine was extending the lives of the arguments (in r0-r3) up until the call to z. This leaves only 3 regs free which isn't enough to preform the doubleword addition. */ /* { dg-do compile } */ /* { dg-options "-O2 -fno-omit-frame-pointer" } */ void z(int); int foo(int a, int b, int c, int d, long long *q) { *q=*q+1; z (a+b+c+d); }
