Irmen de Jong 1f8b42fae5 make user docs and some code comments less convoluted 2026-10-05 20:00:32 +02:00
Irmen de Jong f086918e6f add union types: structs where every field is at offset 0, thus saving memory 2026-09-23 00:07:44 +02:00
Irmen de Jong ef64e2f9a4 fix typed pointer arithmetic p2-p1 to yield the number of elements. fixes #244 2026-09-18 21:22:07 +02:00
Irmen de Jong 7ba2ee9857 added named struct field initializers 2026-09-14 00:56:22 +02:00
Irmen de Jong 9621552056 add 'arena' allocator library 
6502 targets use uword sizes with no alignment overhead; m68k/virtual use
long sizes with even-address alignment. Updated the six pointer examples that used to have their own arena implementation.

Irmen de Jong c55b16f4cb todo 2026-09-09 01:01:16 +02:00
Irmen de Jong 9bf8318b1c Support arrays of struct instances 
- Parser: parse `StructType[N] var` via elementToArray() for
  STRUCT_INSTANCE (Prog8ANTLR.g4, Antlr2KotlinVisitor)
- Desugar: struct-instance bases via addressOfStructInstance(),
  whole-struct `a[i]=a[j]` -> sys.memcopy, inferred `[[...]]`
  and explicit `Struct : [...]` (without ^^) for value arrays;
  reject `^^Struct : [...]` in instance arrays
- 6502: computeStructArrayElementAddress() with 16-bit
  index*structSize scaling (AssignmentAsmGen, AsmGen)
- IR/VM/m68k/new6502: STRUCTDEFS round-trip, loaders, gens
- AstChecker/IdentifiersChecker: reject struct fields that are
  arrays of structs; fix isArray guards
- Docs: structpointers.rst/variables.rst, todo.rst, examples/test.p8
- Tests: TestArraysOfStructs (pointer vs value init, IR round-trip,
  16-bit strides)

Irmen de Jong 94822b8662 Add arrays of struct instances (StructType[N] vars) 
Parser: accept `Type[N] name` between type and identifier
(Prog8ANTLR.g4, Antlr2KotlinVisitor) via elementToArray()
for STRUCT_INSTANCE; CodeDesugarer: handle struct-instance
bases, addressOfStructInstance(), whole-struct memcopy
(points[a]=points[b]), and fix variable-index 16-bit scaling
in 6502 AssignmentAsmGen.computeStructArrayElementAddress();
IR: preserve STRUCTDEFS round-trip, VM loader support;
m68k/new6502/intermediate backends; docs + todo updated.
Limitations: not as struct fields (AstChecker/
AstIdentifiersChecker error) nor as sub params.

Irmen de Jong 014a82a1ee always put all struct types as .struct in asm code to make them all accessible for size and offsets 2025-12-10 21:39:44 +01:00
Irmen de Jong 3e1386a987 remove the -dontsplitarrays compiler option 
it was still there for backward compatibility reasons with really old prog8 code. If you need a word array to be not split, just use @nosplit on the array.
