https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211563 --- Comment #4 from Dimitry Andric <dim@FreeBSD.org> --- Hm, so after hand merging llvm r263417 [1], which fixes your original test case, I tried a buildworld with CPUTYPE=skylake, and I got another crash: fatal error: error in backend: Cannot select: t24: i32 = X86ISD::CMP t48, t51 t48: i1 = truncate t47 t47: i8 = and t32, t35 t32: i8 = X86ISD::SETCC Constant:i8<4>, t30 t31: i8 = Constant<4> t30: i32 = X86ISD::CMP t4, Constant:i8<0> t4: i8 = AssertZext t2, ValueType:ch:i1 t2: i8,ch = CopyFromReg t0, Register:i8 %vreg375 t1: i8 = Register %vreg375 t5: i8 = Constant<0> t35: i8 = X86ISD::SETCC Constant:i8<4>, t34:1 t31: i8 = Constant<4> t34: i32,i32 = X86ISD::SUB t9, Constant:i32<101> t9: i32,ch = CopyFromReg t0, Register:i32 %vreg378 t8: i32 = Register %vreg378 t11: i32 = Constant<101> t51: i1 = truncate t50 t50: i8 = or t32, t38 t32: i8 = X86ISD::SETCC Constant:i8<4>, t30 t31: i8 = Constant<4> t30: i32 = X86ISD::CMP t4, Constant:i8<0> t4: i8 = AssertZext t2, ValueType:ch:i1 t2: i8,ch = CopyFromReg t0, Register:i8 %vreg375 t1: i8 = Register %vreg375 t5: i8 = Constant<0> t38: i8 = X86ISD::SETCC Constant:i8<9>, t37:1 t25: i8 = Constant<9> t37: i32,i32 = X86ISD::SUB t9, Constant:i32<112> t9: i32,ch = CopyFromReg t0, Register:i32 %vreg378 t8: i32 = Register %vreg378 t14: i32 = Constant<112> In function: __vfwscanf So all is not well yet for -march=skylake. I will investigate further, but maybe complete Skylake support is something that has to wait for clang 3.9.0.
