// Test overriding warnings about complex range.
// range.c tests the settings of -complex-range=, and this test covers
// all warnings related to complex range.

// Clang options related to complex range are as follows:
//   -f[no-]fast-math
//   -f[no-]cx-limited-range
//   -f[no-]cx-fortran-rules
//   -fcomplex-arithmetic=[full|improved|promoted|basic]
//   -ffp-model=[strict|precise|fast|aggressive]

// Emit warnings about overriding when options implying different
// complex ranges are specified. However, warnings are not emitted in
// the following cases:
// (a) When the positive/negative form or a different value of the same
//     option is specified. 
//       Example: 
//          `-ffast-math -fno-fast-math`
//          `-fcx-limited-range -fno-cx-limited-range`
//          `-fcx-fortran-rules -fno-cx-fortran-rules`
//          `-fcomplex-arithmetic=full -fcomplex-arithmetic=improved`
//          `-ffp-model=strict -ffp-model=aggressive`
//
// (b) When -ffp-model= is overridden by -f[no-]fast-math. 
//       Example:
//          `-ffp-model=fast -fno-fast-math`
//          `-ffp-model=strict -ffast-math`
