Presumably it also went into the gcc GNATS system.

The assembler code appears to be exactly the same on gnat 3.14p, where it works. In fact, I think the whole file is the same. > I don't know why but,,, well the assambler doesn't work. I suspect that support for any assembler code is badly broken, but my knowledge of assembler code in Ada is somewhat flakey. I tried moving the assembler code to me source code, but it stopped working even with gnat 3.14p, which was perviously working. It wouldn't surprise me if the assembler code is working, but for some reason that parameters aren't getting passed to/from the Ada code. At one stage I did look at this using a debugger and viewing the assembler code, but I couldn't see anything that looked obviously wrong. > In the rpm from Ada for Linux Team the version uses interface to > C-functions and that version seems to work. > > > PSIf I've done something wrong by posting this mail, pleas don't Nothing wrong that I am aware of. > hesitate to tell me. Is there a simple solution out there ??? please > tell me. DS Create interfaces to the C-functions? Use gnat 3.14? Sorry, these are the only two solutions I know of (not tested the first one myself). -- Brian May <bam@snoopy.apana.org.au>
