Revision as of 15:16, 17 October 2019
| Feature | Status | Description |
|---|---|---|
| Assembly (textual wasm) | working | Pick an assembler utility that's sequence instruction (FPC) friendly
FPC should produce a textual assembly file |
| Basic function calls and local variables | working | Implement direct function calls, with passing basic parameters (that don't require any memory. I.e. int and floats) |
| Verify float-point values | As the float points are being converted from the textual format. it's necessary to make sure that the proper values are generated | |
| Global variables | working | Implement symbol reference to global variables (basic or complex)
Consider linking - as the index of symbols can change. (Wasm binaries are index based ) |
| Stack/Call frame support | working | WebAssembly doesn't have any native stack and/or frame support.
It has to be emulated using global and local variables. |
| Indirect function calls | in progress | WebAssembly has a specific way of indirect calls
Needed for vmt and procedure variables (callback) calls |
| VMT | Support for calls via virtual method table | |
| RTL | not in scope |
Long-term
| Feature | Status | Description |
|---|---|---|
| Internal Writer | The binary wasm format is well defined and could be implemented within FPC | |
| Internal Linker |
