<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>
