[swift-evolution] [Draft] Expanding Build Configuration Tests for Simulator and Device targets

[Alex Martini]

The reference for build configuration statements[1] has a list of platforms and operating systems.  If that list is out of date, it's a documentation bug — so thanks for pointing that out!

<rdar://problem/25244216> TSPL: Build configuration statements is missing Windows, FreeBSD, powerpc64, and powerpc64le

If you want to look in source, the list in lib/Basic/LangOptions.cpp reads as follows:

static const StringRef SupportedConditionalCompilationOSs[] = {
  "OSX",
  "tvOS",
  "watchOS",
  "iOS",
  "Linux",
  "FreeBSD",
  "Windows"
};

static const StringRef SupportedConditionalCompilationArches[] = {
  "arm",
  "arm64",
  "i386",
  "x86_64",
  "powerpc64",
  "powerpc64le"
};
