-; Test that fast math lib call simplification of double math function to float
-; equivalent doesn't occur when the calling function matches the float
-; equivalent math function. Otherwise this can cause the generation of infinite
-; loops when compiled with -O2/3 and fast math.
-
-; Test case C source:
-;
-;   extern double exp(double x);
-;   inline float expf(float x) { return (float) exp((double) x); }
-;   float fn(float f) { return expf(f); }
-;

-;   clang -cc1 -O2 -ffast-math -emit-llvm -disable-llvm-passes -triple x86_64-unknown-unknown -o - <srcfile>
