Unlike floating point integer can easily expanded. Most CPU's have a so called "Carry" flag for integer expasion. This comes from way back 8bit times where integer expansion was esential. Of corse a 12 bit type on a 32 bit CPU will only be 12 bit in a packed array - Thurs, Nov 25 2004 9:47 am 1 message, 1 author http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/d32116f6f91c319f test with task - 3 new ---------------------- ...foo.adb:10:40 "dummy" is not a visible entity of "bar" - Thurs, Nov 25 2004 2:52 am 3 messages, 3 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/f8ae7c8799572552 resources_on_ada.html - 1 new ----------------------------- resources_on_ada.html updated: lots of red "NEW"s and another quote of the day ;-) any suggestions for improvement are welcome! - Thurs, Nov 25 2004 11:15 am 1 message, 1 author http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/9f0b6bcc60c3b134 Moving from Ada 83 to Ada 95 - 2 new ------------------------------------ ...If the original was well written (i.e. with portability in mind) then it should be very straight forward. I had the misfortune to try with some very badly written code - 'with'-ing in package System into every other package and using the non-standard items in it! Other things that needed changing - Thurs, Nov 25 2004 11:28 am 2 messages, 2 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/87dcbc853960d3bd Offical Ada FAQ - 14 new ------------------------ ...I think a whole section of FAQs about SPARK would be very useful... we'll try to come up with some soon! - Rod - Thurs, Nov 25 2004 5:03 am 14 messages, 8 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/7833d36bbd0d6fcd ANNOUNCE: XIA 0.20 now available - 1 new ---------------------------------------- ...URL: [link] - Thurs, Nov 25 2004 1:17 pm 1 message, 1 author http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/68050e1f9ef103bd Generic,procedure and visibility. - 5 new ----------------------------------------- sorry for the italian-naming :) package Generico is generic with procedure Lavora; package Nascosto is procedure Inizia; end Nascosto; end Generico; package body Generico is package body Nascosto is procedure Inizia is begin Lavora; end Inizia; end Nascosto; begin lavora; --error:"lavora" in not visibile - Thurs, Nov 25 2004 8:36 am 5 messages, 4 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/ef0a2057d81387f4 Possible Memory Leak - 1 new ---------------------------- ...Thank you. With AI-147 in mind, I will assume that for the type of problem in my orginal posting: 1) Where a compiler uses a temporary for assignment, then Adjust and Finalize are applied so that the target variable is adjusted and no memory leaks occur. 2) It is not necessary to introduce an aliased component just to - Thurs, Nov 25 2004 5:49 pm 1 message, 1 author http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/5799fe4f91b50de GNAT Ada.Streams Bug? - 3 new ----------------------------- This is on gnat-3.14p on debian (debian's package library doesn't seem to provide 3.15p), so this may be fixed by now: I am running into a Ada.Streams problem with 24 bit values (3 bytes). For example, if you use Ada.Streams to read in a partition table, defined as follows, with 3.14p, you'll read more bytes than needed - Thurs, Nov 25 2004 12:41 pm 3 messages, 3 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/1ea59bb198e88f9f Windows Ada database support. - 2 new ------------------------------------- ...APQ Plug: The good news is that you do have "choice". I have been dragging my feet in getting the latest version of APQ out, but the published version supports PostgreSQL and MySQL in OO form. The version to be released (pending install scripts), supports PostgreSQL, MySQL and SYBASE (I have been distracted with another fun and absorbing project lately). - Thurs, Nov 25 2004 12:50 pm 2 messages, 2 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/bf02c238a92156a3 Would You Fly an Airplane with a Linux-Based Control System? - 3 new -------------------------------------------------------------------- ...A small but, I think, important correction. The hardware at the center of the failure was apparently built around the Motorola 68020/68881 chips, not the MIL-STD-1750. The "Operand Error" that triggered the failure is a hardware exception generated by the FPU when, among other conditions, a float-to- integer conversion exceeds - Thurs, Nov 25 2004 10:28 am 3 messages, 3 authors http://groups-beta.google.com/group/comp.lang.ada/browse_thread/thread/ac9405996d0dcb7f [Announce] AVR-Ada V0.2.1 released - 1 new ------------------------------------------ It's been available for almost three weeks now, but I was away on a business trip without good internet access.
