## Additions
|
||||
|
||||
- LTO support: Allow using LTO/IPO by setting `FSFW_ENABLE_LTO=1`. CMake is able to detect whether
|
||||
the user compiler supports IPO/LPO. LTO is on by default now. Most modern compilers support it,
|
||||
can make good use of it and it usually makes the code faster and/or smaller.
|
||||
After some more research:
|
||||
Enabling LTO will actually cause the compiler to only produce thin LTO by adding
|
||||
`-flto -fno-fat-lto-objects` to the compiler options. I am not sure this is an ideal choice
|
||||
because if an application linking against the FSFW does not use LTO, there can be compile
|
||||
issues (e.g. observed when compiling the FSFW tests without LTO). This is a known issue as
|
||||
can be seen in the multiple CMake issues for it:
|
||||
- https://gitlab.kitware.com/cmake/cmake/-/issues/22913,
|
||||
- https://gitlab.kitware.com/cmake/cmake/-/issues/16808,
|
||||
- https://gitlab.kitware.com/cmake/cmake/-/issues/21696
|
||||
Easiest solution for now: Keep this option OFF by default.

- Linux HAL: Add wiretapping option for I2C. Enabled with `FSFW_HAL_I2C_WIRETAPPING` defined to 1

||||
- Dedicated Version class and constant `fsfw::FSFW_VERSION` containing version information
|
||||
inside `fsfw/version.h`
