- Speaking for an Ada vendor, I disagree with Mike Ryer's
- assessment of ASIS. ASIS is not "everything that TeleSoft and
- Rational happen to have in their libraries". The current ASIS
- specification was agreed upon by the ASIS Working Group which
- includes many compiler users and compiler implementers.
- TeleSoft and Rational contributed technology to the ASIS
- standard but many others had a say in what ASIS eventually
- became. The same is true for the future of ASIS and the
- current and future revision of the proposed standard are
- debated by a very active group (at meetings or through email).
- Thus I believe it is unfair to state that TeleSoft and/or
- Rational controlled the definition of the standard to suit
- their particular compiler architectures.
-
- I believe it is also unfair to say that implementing ASIS
- causes compiler to be slower and library to be larger. The
- RISCAda compiler for SPARC has excellent compile time
- performance relative to other SPARC compilers. On many
- benchmarks run by customers, it came on top of all SPARC
- compilers. THis is an ASIS compliant compiler.
- The size of the libraries for RISCAda compiler may be larger
- than for some other compilation systems but I have yet to talk
- to a customer for whom this has been a very significant
- problem.
-
- I think Mike overlooks the most important benefit of the ASIS
- standard. Ever since Ada came onto the scene, the power of the
- language has been locked up in proprietary compilation library
- systems that only compiler vendors could have access to. Thus
- no other CASE tool vendors were able to exploit all the
- benefits of the Ada language. With ASIS, CASE tool vendors can
- develop Ada-smart tools that are not compiler
- vendor-dependent. That fact alone will provide an incentive to
- CASE vendors to build more Ada tools which, in turn, will
- contribute to the growth of our industry. Ada need to open up
- to the rest of the software world and ASIS is one of the
- keys that will allow that (as is A.O.I, the ALSYS interface
- that allows integration of Ada compilation systems at the
- control level).
-
- As far as vendor support, TeleSoft and now the ALSYS Group do
- support ASIS. An ASIS toolkit is available from ALSYS for the
- RISCAda product and an ASIS interface will be available from
- ALSYS for the AdaWorld products in 1993. Also, at the meeting
- of the ASIS Working Group in July in Washington, Steve
- Zeigler, VP Eng. at Verdix, voiced his support for ASIS and
- made the statement that Verdix would support ASIS in the
- future (I am only stating here the position that Steve took at
- the meeting, for more details on Verdix position please talk
- to them :)
-
- ASIS has received enthusiastic support from the users
- community. From our standpoint, it has also been a commercial
- success. I believe that ASIS will be one key contributor to
- growing the Ada market and developin the Ada community beyond its
- traditional boundaries.
-
- The investment to implement ASIS will vary from vendor to
- vendor but I believe the pay-off is well worth it.
