[PATCH] D109950: [Clang] Enable IC/IF mode for __ibm128

[Elizabeth Andrews via Phabricator via cfe-commits]

eandrews added a comment.

This has changed the behavior for -

  // Define __complex128 type corresponding to __float128 (as in GCC headers).
  typedef _Complex float __attribute__((mode(TC))) __complex128;
  
  void check() {
  // CHECK: alloca { fp128, fp128 }   <----- Fails because alloca { x86_fp80, x86_fp80 } is generated instead
  __complex128 tmp;
  }

In TargetInfo.cpp, we used to check long double format to decide whether to return LongDouble or Float128. This patch doesn't, and so the return value has changed from FloatModeKind::Float128 to clang::FloatModeKind::LongDouble (ExplicitType).  Should we be checking the format?
