Add a Rust make helper that collects crate input files, and use it for the Rust hello and slint examples. This makes the generated Rust static libraries depend on the crate sources, manifests, build scripts. Hook the libraries into both context and all, so re-running make after editing Rust inputs rebuilds the crate. Signed-off-by: Shoji Tokunaga <toku@mac.com>

# Generate Rust target triple based on LLVM architecture configuration
|
|
#
|
|
# Uses the following LLVM variables directly:
|
|
# - LLVM_ARCHTYPE: Architecture type (e.g. thumbv7m, riscv32)
|
|
# - LLVM_ABITYPE: ABI type (e.g. eabi, eabihf)
|
|
# - LLVM_CPUTYPE: CPU type (e.g. cortex-m23, sifive-e20)
|
|
#
|
|
# Supported architectures and their target triples:
|
|
# - x86: i686-unknown-nuttx
|
|
# - x86_64: x86_64-unknown-nuttx
|
|
# - armv7a: armv7a-nuttx-eabi, armv7a-nuttx-eabihf
|
|
# - thumbv6m: thumbv6m-nuttx-eabi
|
|
# - thumbv7a: thumbv7a-nuttx-eabi, thumbv7a-nuttx-eabihf
|
|
# - thumbv7m: thumbv7m-nuttx-eabi
|
|
# - thumbv7em: thumbv7em-nuttx-eabihf
|
|
# - thumbv8m.main: thumbv8m.main-nuttx-eabi, thumbv8m.main-nuttx-eabihf
|
|
# - thumbv8m.base: thumbv8m.base-nuttx-eabi, thumbv8m.base-nuttx-eabihf
|
|
# - riscv32: riscv32imc/imac/imafc-unknown-nuttx-elf
|
|
# - riscv64: riscv64imac/imafdc-unknown-nuttx-elf
|
|
# - aarch64: aarch64-unknown-nuttx-macho for sim on macOS,
|
|
# aarch64-unknown-nuttx otherwise
|
|
#
|
|
# Usage: $(call RUST_TARGET_TRIPLE)
