3 years ago This appears to be a bug in LLVM. Are you able to reproduce this? It would help to attach the llvm ir that is causing the crash. For example, after running the failing command
/usr/bin/python3.8 /home/ubuntu/swift/utils/scale-test --swiftc-binary=/home/ubuntu/build/buildbot_linux/swift-linux-aarch64/bin/swiftc --tmpdir=/home/ubuntu/build/buildbot_linux/swift-linux-aarch64/validation-test-linux-aarch64/compiler_scale/Output/scale_neighbouring_getset.gyb.tmp --sum-multi --begin 5 --end 16 --step 5 --select TypeCheckFunctionBodyRequest /home/ubuntu/swift/validation-test/compiler_scale/scale_neighbouring_getset.gybYou can see the specific compiler command that crashed
['/home/ubuntu/build/buildbot_linux/swift-linux-aarch64/bin/swiftc', '-frontend', '-c', '-o', 'out.o', '-primary-file', 'in3.swift', 'in0.swift', 'in1.swift', 'in2.swift', 'in4.swift', '-stats-output-dir', '/home/ubuntu/build/buildbot_linux/swift-linux-aarch64/validation-test-linux-aarch64/compiler_scale/Output/scale_neighbouring_getset.gyb.tmp/tmpaiusiqwf']We can replace -c -o out.o with -emit-ir -o out.ll
'/home/ubuntu/build/buildbot_linux/swift-linux-aarch64/bin/swiftc' '-frontend' '-emit-ir' '-o' 'out.ll' '-primary-file' 'in3.swift' 'in0.swift' 'in1.swift' 'in2.swift' 'in4.swift' '-stats-output-dir' '/home/ubuntu/build/buildbot_linux/swift-linux-aarch64/validation-test-linux-aarch64/compiler_scale/Output/scale_neighbouring_getset.gyb.tmp/tmpaiusiqwf'And attach the "out.ll" file. You can also verify that this crashes llvm on its own using `llc`. Something like
'/home/ubuntu/build/buildbot_linux/llvm-linux-aarch64/bin/llc' '-O0' '-frontend' '-emit-ir' '-o' 'out.ll'

Issue Description:
Hi,
today I tried to compile Swift on Ubuntu 20.04 on an AWS c6g instance. (c6g is using Amazon's Arm-based AWS Graviton2 processors). The build succeeded, but four tests failed on main. (swift-DEVELOPMENT-SNAPSHOT-2020-09-23-a)
The test failure log is attached.
