14 Vendors, 87 Compilers on Major Systems
When the Ada Joint Program Office (AJPO) first considered the transition to Ada 95, it concluded that it was vital for the most widely used platforms to get validated support as early as possible.
To a significant extent, that was accomplished last year. By the spring of 1996, five vendors had validated 14 compilers -- covering the Patriot missile system, and major platforms from Digital Equipment Corp., Silicon Graphics, Inc., Hewlett-Packard, Windows NT and 95, and the IBM RS/6000.
Since then, those five vendors and 9 others coming on board have been working to spread the range of hosts and targets, and to increase the choices available for important platforms.
By the summer of 1997, the number of vendors had grown to 14, and they were offering 87 validated compilers. The vendors are listed in Table 1; as you can see in Table 2, much of the increase reflects a greater range of options in popular host platform families, with 18 compilers for PC/80x86 platforms and 34 for Sun platforms. Additionally, there is now a validated compiler hosted on the Macintosh.
Coverage has also increased for targets (Table 3): supported platforms now include Motorola MVME chips, Lockheed Martin RAD 6000, Siemens Nixdorf RM 200 processors, and a number of simulators.
The nonvalidated world
Strictly speaking, compiler validation is necessary only for producing the executable code that will be fielded in a DOD project. For those of you doing work on your own, or preliminary work prior to producing fielded code, there's always been the freely available GNU Ada 95 Translator (the GNAT compiler) and it has been ported to several platforms. (See Table 4 for list of GNAT's known ports.)
Also, the Public Ada Library includes the AVLAda9X Ada 95 compiler for MS-DOS. The Ada Information Clearinghouse -- 800/232-4211 -- can give you information on obtaining these compilers.
