## Create an EBS snapshot or an AMI at this point because the above takes ~30 minutes

## Build Instructions 

## Specify the release you want to build
SWIFT_VERSION=5.8
# SWIFT_VERSION=5.9
./utils/update-checkout --scheme release/$SWIFT_VERSION

## IMPORTANT : to build a version >= 5.9, you must install swift 5.8 and make sure `swift` is in the PATH

## Building 
# simple build
# ./utils/build-script --release-debuginfo --skip-early-swift-driver
# or 
# build and package
./utils/build-script --preset=buildbot_linux,no_assertions,no_test install_destdir=/tmp installable_package=/tmp/swift-${SWIFT_VERSION}-amazonlinux2023.tar.gz

## Cleaning in between builds
rm -rf ../build
rm -rf /tmp/usr
