# Build and install PTOAS in editable mode against an existing LLVM/MLIR
# build. The persistent build directory can subsequently be used with Ninja,
# for example: ninja -C build check-pto.
#
# Usage: quick_install.sh [-v]
#   -v   verbose: trace commands and pass -v to every pip invocation.
#
# Optional env:
#   LLVM_BUILD_DIR   - default: <repo-parent>/llvm-project/build-shared
#   PTO_BUILD_DIR    - default: <repo>/build
#   PYTHON_BIN       - default: python
