***Watch out for CCompiler bug(s)***
I'm now willing to claim that the following bugs are fixed in the 14.0 version of CCompiler, but this is left here for documention purposes. --bj, January 11, 1988 11:20:22 am PST
Bug #1: SEQUENCES have bad description routines generated for these data types. What needs to be done is whenever you run CCompiler, you MUST hand edit the file RapunzelDescription.mesa and change all occurances of the string "BASE[p]" into "p".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DescribeSeqCmd: Courier.Description = {
p:
LONG
POINTER
TO Rapunzel.SeqCmd = notes.noteSize[
SIZE[Rapunzel.SeqCmd]];
notes.noteArrayDescriptor[p, SIZE[Rapunzel.Cmd], CARDINAL.LAST];
FOR i:Rapunzel.SeqCmdIndex
IN [0..
LENGTH[p])
DO
notes.noteParameters[@p[i], DescribeCmd];
ENDLOOP;
};
instead of:
notes.noteArrayDescriptor[BASE[p], SIZE[Rapunzel.Cmd], CARDINAL.LAST];
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Bug #2: CHOICES have bad description routines generated for their data types. What needs to be done is whenever you run CCompiler, you MUST hand edit the file RapunzelDescription.mesa and change all occurances of passages which define the sizes of the individual variant type (so that they do include the type word). These passages look like:
sizes:
ARRAY [0..#)
OF
CARDINAL ¬ [
SIZE[type1], SIZE[type2], ...];
they should look like:
SIZE[tag1 variantRecordType], SIZE[tag2 variantRecordType], ...];
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DescribeCmd: Courier.Description = {
p:
LONG
POINTER
TO Rapunzel.Cmd = notes.noteSize[
SIZE[Rapunzel.Cmd]];
sizes:
ARRAY [0..2)
OF
CARDINAL ¬ [
SIZE[Rapunzel.PokeShortCmd], SIZE[Rapunzel.PeekShortCmd]];
notes.noteChoice[p, SIZE[Rapunzel.Cmd], LONG[DESCRIPTOR[sizes]]];
WITH variant: p
SELECT
FROM
pokeShort => notes.noteParameters[@variant.pokeShort, DescribePokeShortCmd];
peekShort => notes.noteParameters[@variant.peekShort, DescribePeekShortCmd];
ENDCASE;
};
instead of:
SIZE[pokeShort Rapunzel.Cmd], SIZE[peekShort Rapunzel.Cmd]];
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Bug #3: Empty Records have bad description routines generated for these data types. What needs to be done is whenever you run CCompiler, you MUST hand edit the file RapunzelDescription.mesa and change all occurances of passages which would invoke a descripton routine for an empty record so that the descrption routine is NIL (so that the runtime won't check it). This passage looks like:
pokeShort => notes.noteParameters[@variant.pokeShort, DescribePokeShortResult];
they should look like:
pokeShort => notes.noteParameters[@variant.pokeShort, NIL];
In addition, the sizes ARRAY is generated wrong; it says:
sizes:
ARRAY [0..2)
OF
CARDINAL ¬ [
SIZE[pokeShort Rapunzel.Cmd], SIZE[peekShort Rapunzel.Cmd]];
but it should say:
sizes:
ARRAY [0..2)
OF
CARDINAL ¬ [
SIZE[pokeShort Rapunzel.Result], SIZE[peekShort Rapunzel.Result]];
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DescribeResult: Courier.Description = {
p:
LONG
POINTER
TO Rapunzel.Result = notes.noteSize[
SIZE[Rapunzel.Result]];
sizes:
ARRAY [0..2)
OF
CARDINAL ¬ [
SIZE[pokeShort Rapunzel.Result], SIZE[peekShort Rapunzel.Result]];
notes.noteChoice[p, SIZE[Rapunzel.Result], LONG[DESCRIPTOR[sizes]]];
WITH variant: p
SELECT
FROM
pokeShort => notes.noteParameters[@variant.pokeShort, NIL];
peekShort => notes.noteParameters[@variant.peekShort, DescribePeekShortResult];
ENDCASE;
};
instead of:
sizes:
ARRAY [0..2)
OF
CARDINAL ¬ [
SIZE[pokeShort Rapunzel.Cmd], SIZE[peekShort Rapunzel.Cmd]];
pokeShort => notes.noteParameters[@variant.pokeShort, DescribePokeShortResult];
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
