This is the Ada Backend generating Ada code from the machine code computed
|
|
2
|
from a Lustre file.
|
|

|
|
|
4
|
The backend is split in several files described in this README.
|
|
5
|
|
|
6
|
=> misc_lustre_function.ml
|
|
7
|
Some fonction on pure Lustre machine code, no printers
|
|
8
|
or anything related to Ada. It just compute information from the Machine Code.
|
|
9
|
It contains mostly the unification code used for polymorphic type. It is
|
|
10
|
important since the Arrow node is polymorphic.
|
|
11
|
|
|
12
|
=> misc_printer.ml
|
|
13
|
Some general format printer function, not related at all
|
|
14
|
to Ada but used by this backend.
|
|
15
|
|
|
16
|
=> ada_printer.mli
|
|
17
|
=> ada_printer.ml
|
|
18
|
It contains Type representing some part of Ada syntaxe and printers function
|
|
19
|
to generates it. There is nothing specifics to Lustre in this file. It is
|
|
20
|
mostly printers for the declarative part of Ada. The printer functions takes in
|
|
21
|
general directly printer function build by other files(like ada_backend_common.ml)
|
|
22
|
to print instruction and expression contained in the declaration.
|
|
23
|
For example, the printer for the declaration of a variable will take
|
|
24
|
two printer functions as argument:
|
|
25
|
- pp_type: printing the type
|
|
26
|
- pp_name: printing the variable name
|
|
27
|
The printer will looks like :
|
|
28
|
--
|
|
29
|
let pp_var_decl pp_type pp_name =
|
|
30
|
fprintf fmt "%t : %t" pp_type pp_name
|
|
31
|
--
|
|
32
|
|
|
33
|
=> ada_backend_common.mli
|
|
34
|
=> ada_backend_common.ml
|
|
35
|
It contains function printing Ada code(instruction and exression) from Machine
|
|
36
|
Code. This functions are used or could be used for ads and/or adb and/or
|
|
37
|
wrappers.
|
|
38
|
|
|
39
|
=> ada_backend_ads.ml
|
|
40
|
It contains function printing Ada code(instruction and exression) from Machine
|
|
41
|
Code for the Ads file.
|
|
42
|
|
|
43
|
=> ada_backend_adb.ml
|
|
44
|
It contains function printing Ada code(instruction and exression) from Machine
|
|
45
|
Code for the Adb file.
|
|
46
|
|
|
47
|
=> ada_backend_wrapper.ml
|
|
48
|
It contains function printing Ada code(instruction and exression) from Machine
|
|
49
|
Code for :
|
|
50
|
- an adb file witha main function containg a loop calling step.
|
|
51
|
- a project file
|
|
52
|
- a configuration file
|
|
53
|
|
|
54
|
=> ada_backend.ml
|
|
55
|
It contains the main function of the backend which perform the unification
|
|
56
|
and write all the files using the previsous code.
