Implement the asan:stack statement

2026-04-08T14:04:12Z

This statement allows programmers to reserve a memory range for the stack. This is useful to reserve a memory region which is not attached to any variable, and: 1. It is a way to safely reserve space on the $0100 page. 2. The --stats/--write-info flags will be able to add up the memory space reserved for the stack. 3. Future tooling might be able to use this value as a way to detect stack overflows. Signed-off-by: Miquel Sabaté Solà

asan: don't complain on arithmetic with addresses

2026-02-06T13:05:37Z

This was already the case for plain addresses, but it was not being considered in the case of an arithmetic operation. Signed-off-by: Miquel Sabaté Solà

asan: Add fixes on absolute/indirect addressing

2025-09-03T21:16:54Z

The check was not being applied on certain conditions. Signed-off-by: Miquel Sabaté Solà

Apply asan:ignore also when bundling

2025-09-03T20:40:38Z

This way instructions which might make use of bare memory numbers can freely ignore the address sanitizer when it actually makes sense. Signed-off-by: Miquel Sabaté Solà

Validate that memory access is done via variables

2025-09-03T18:45:54Z

The address sanitizer is now able to detect whenever in an instruction a memory access is done without using variables. This is now detected for all instructions except for branching, which falls outside of this scope. Moreover, simple arithmetics is allowed and bounds are checked for simple cases. That being said, more involved bound checks should be done with other tools (e.g. emulators). Signed-off-by: Miquel Sabaté Solà
