[Bug target/42536] [4.4/4.5 regression] ICE in spill_failure, at reload1.c:2141

------- Comment #2 from jakub at gcc dot gnu dot org  2010-01-02 14:30 -------
With 3 register vars in the function (ebx, edi, esi) on the register starved
ix86 the error is tollerable.  From the 8 registers the programmer takes 3,
%esp is fixed, without -fomit-frame-pointer %ebp is fixed too, which leaves
just %eax, %edx and %ecx for register allocation.  Even if this happens to
compile, the result can't work fast, as almost all insns need to have
temporaries spilled and reread back.
