Don't you have the same problem with other atoms, e.g. variable names? This sounds like something that should be implemented in the language's runtime library.

...t;: In my case, the CSE does not work, although it does work for the example in 4.3: "ready> def foo(x) sin(x)*sin(x) + cos(x)*cos(x); ready> Read function definition: define double @foo(double %x) { entry: %calltmp = call double @sin(double %x) %calltmp1 = call double @sin(double %x) %multmp = fmul double %calltmp, %calltmp1 %calltmp2 = call double @cos(double %x) %calltmp3 = call double @cos(double %x) %multmp4 = fmul double %calltmp2, %calltmp3 %addtmp = fadd double %multmp, %multmp4 ret double %addtmp...

...m ... I tried setting that right after Function::Create but I still get the same result (though flagged with "readonly") declare double @sin(double) readonly declare double @cos(double) readonly define double @foo(double %x) readonly { entry: %calltmp = call double @sin(double %x) %calltmp1 = call double @sin(double %x) %multmp = fmul double %calltmp, %calltmp1 %calltmp2 = call double @cos(double %x) %calltmp3 = call double @cos(double %x) %multmp4 = fmul double %calltmp2, %calltmp3 %addtmp = fadd double %multmp, %multmp4 ret double %addtmp }
