+<p>llvm treats calls to some functions with names and arguments that match the
+standard C library as being the C library functions, and may perform
+optimizations or generate code for them under that assumption.  These
+functions currently include:
+acos, asin, atan, atan2, ceil, cos, cosf, cosh, exp, fabs, floor, fmod, log,
+log10, malloc, pow, sin, sinh, sqrt, sqrtf, sin, sinf, tan, tanh.</p>
