[cfe-dev] Clang, #include <math.h>

<math.h> is part of the C standard library, not part of the compiler headers. Clang does not provide it.

You could look into one of the "standard" standard libraries, such as RedHat Newlib or Glibc, compile that yourself for your target and point Clang at its /include directory.

I'm working on a new llc target and would like to generate .ll code with Clang.

I find that I can't #include <math.h>, if I specify my target, or eg mips, arm, bfin...

What must be done in order to do this?

Thank you,

Jonas Paulsson
