kinke <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from kinke <[email protected]> --- This is specific to DMD and should be an issue with -m32mscoff too. As you said, the MSVC `long double` type is a (for C++, differently mangled than double) 64-bit double (IIRC, Microsoft outright forbids X87 usage in kernel code), while DMD goes with 80-bit X87 reals for those targets (so printf and scanf etc. from the MS runtime cannot be used without converting to lower precision first). LDC uses 64-bit reals for MSVC targets, so this works. The deprecation wrt. double is IMO valid, as `%Lg` with a double isn't portable and just happens to work for targets with 64-bit reals, but this deprecation should IMO be host-agnostic, i.e., not suddenly popping up when targeting AArch64 or Posix x86. --
