Add scripts/slint-dev-fast.sh: a DEBUG (non-release) build for quick visual iteration — opt-level 0 so the giant Slint-generated module skips the heavy LLVM passes, plus the mold linker, no debuginfo, and the nightly parallel frontend. It builds into target/debug, separate from the release cache. slint-dev.sh (release, kept for perf measurement) gains the mold linker and bumps the frontend threads 8 -> 16 — both only cut compile time, the optimised binary is unchanged. cc

# QBZ Slint — FAST dev build/run (DEBUG, *not* release).
|
|
#
|
|
# ADDITION to ./slint-dev.sh, NOT a replacement. Use this for quick, purely
|
|
# visual / layout iteration where runtime performance does NOT matter — it is
|
|
# dramatically faster to compile than the release build because:
|
|
# - debug profile (opt-level 0) → the giant Slint-generated module skips the
|
|
# heavy LLVM optimisation passes that dominate the release build,
|
|
# - the `mold` linker (much faster than the default `ld`),
|
|
# - NO debuginfo (`-C debuginfo=0`) → less to generate AND less to link,
|
|
# - the nightly PARALLEL FRONTEND (`-Z threads`) across cores.
|
|
# Debug builds live in target/debug, separate from the release target/release,
|
|
# so the two scripts don't invalidate each other's cache.
|
|
#
|
|
# DO NOT use this to judge performance — the binary is unoptimised. Always do a
|
|
# final pass with ./slint-dev.sh (release) before trusting runtime behaviour.

# RUSTFLAGS overrides .cargo/config.toml, so the AES-NI/SSSE3 features are
|
|
# re-listed here (keep in sync with slint-dev.sh / .cargo/config.toml).
