The three files libavr's consumers carry, in the leaf-application shape: nothing vendors this repo, so .clangd names the one build tree an editor should read (build/atmega328p-generated) beside the stand-ins clang needs for GCC's AVR dialect; .vscode/settings.json passes --query-driver and names the toolchain prefix for the window that opens this folder. The libavr pin advances to the editor-audit fixes. One residue stays red and is the documented frontend divergence, not a defect: thermistor.hpp's consteval Beta-equation table folds __builtin_log under GCC, which clang refuses to fold in a constant expression -- the same class as libavr's breathe example and its __builtin_cos.

Add:

|
# clang has no 24-bit integer and GCC's are keywords, not macros, so the
|
|
# editor needs a stand-in for avr::uint24_t. The next width up is the only
|
|
# one available — clang rejects _BitInt(24) on this target.

|
# clangd forwards the driver's system includes but not its own header
|
|
# directory, so <stdint.h> resolves to avr-libc's, which still gates the

Remove:
|
|
# The build promotes warnings for the compiler that has to be right about

# colour reserved for things that do not compile.

Suppress:

# clang's AVR `signal` attribute takes no arguments and it knows none of

# progmem, naked or OS_main. A misspelling is what the build is for.
