Ada bindings to IEEE Std 1003.1-1990 have recently become a standard (IEEE Std 1003.5), and work is well underway on Ada bindings to Realtime Extensions which will soon amend 1003.1. The NGCR Operating System Standards Working Group needs information on Ada implementations which have incorporated or plan to incorporate some or all of these interfaces into their delivered product, either bundled or as an option. Of academic interest are "wrapper" bindings for target systems which are assumed to be running under control of a POSIX compliant operating system already providing "C" (or some other language) bindings to OS services. But because the NGCR program emphasizes MCCR (Mission Critical Computer Resources) applications, which often utilize embedded processors and have hard realtime deadlines, we are much more interested in the so-called "bare machine" Ada targets. Such Ada implementations typically include a vendor specific realtime OS which supports the Ada Runtime Environment and, in addition, usually supplies an additional set of vendor specific OS services. In the interest of portability (as in the "P" of POSIX), it is desirable that Ada vendors implement a standard set of service interfaces as defined by IEEE Std 1003.5 (and eventually 1003.20 and others). Since it is our goal to determine how much industry support there is for current and future POSIX standards, one aspect of this is the extent to which these "bare machine" Ada RTEs will become POSIX compliant. Therefore, if you are a vendor or user of existing or proposed products which support POSIX Ada bindings (especially "bare machine" target implementations), please contact me with information about these products.
