[PATCH] D29804: Fully qualify (preprend ::) calls to math functions from libc

[Mehdi AMINI via Phabricator via cfe-commits]

mehdi_amini created this revision.

This can cause a compile failure in cases like:

double log(double);
namespace foo {

  namespace log {}

}
using namespace foo;
void bar(int i) {

  log((double)i);

}
