static bool shouldAddRequirement ( Module M,
StringRef  Feature,
bool IsRequiresExcludedHack 
)
static

Whether to add the requirement Feature to the module M.

This preserves backwards compatibility for two hacks in the Darwin system module map files:

  1. The use of 'requires excluded' to make headers non-modular, which should really be mapped to 'textual' now that we have this feature. We drop the 'excluded' requirement, and set IsRequiresExcludedHack to true. Later, this bit will be used to map all the headers inside this module to 'textual'.

    This affects Darwin.C.excluded (for assert.h) and Tcl.Private.

  2. Removes a bogus cplusplus requirement from IOKit.avc. This requirement was never correct and causes issues now that we check it, so drop it.
