Testcase demonstrating interference between assembler statements

This test case exhibits the following behaviour on 4.1.1 as well as 3.4.6:

-O1 -fPIC -fomit-frame-pointer -DDO_SINGLE
 X    -            -                -      works
 X    X            -                -      expected errors
 X    -            X                -      works
 X    X            X                X      works
 X    X            X                -      fails: error in both:54
 -    X            X                X      fails: error in f1:25

In the two cases marked failures, the error message is the following:
can't find a register in class `GENERAL_REGS' while reloading `asm'
