iOS platform definition (and where to get all os and cpu arch supported)

[mratsim]

I'm curious what defines the iOS constant (if it's actually defined).

In platform.nim I see no mention of it even though osMacosx and osAndroid are defined there:

Nim/compiler/platform.nim

Lines 19 to 25 in af0c497

	type
	TSystemOS* = enum # Also add OS in initialization section and alias
	# conditionals to condsyms (end of module).
	osNone, osDos, osWindows, osOs2, osLinux, osMorphos, osSkyos, osSolaris,
	osIrix, osNetbsd, osFreebsd, osOpenbsd, osDragonfly, osAix, osPalmos, osQnx,
	osAmiga, osAtari, osNetware, osMacos, osMacosx, osHaiku, osAndroid, osVxworks
	osGenode, osJS, osNimVM, osStandalone, osNintendoSwitch

Searching for iOS in the code shows that it's used in 2 places:

Nim/lib/pure/includes/osenv.nim

Line 61 in 72e15ff

useNSGetEnviron = (defined(macosx) and not defined(ios)) or defined(nimscript)

Nim/lib/system/syslocks.nim

Lines 141 to 144 in 72e15ff

	when defined(ios):
	# iOS will behave badly if sync primitives are moved in memory. In order
	# to prevent this once and for all, we're doing an extra malloc when
	# initializing the primitive.

Are there other places than platform.nim that defines compile-time target specific constants?

Pinging @yglukhov once more. (I would like to close this)

I use --os:macosx -d:ios to compile to ios.

Well the question was answered.
