dart compile exe doesn't work for 32-bit SDK

[nex3]

If I download the 32-bit Linux Dart SDK (version 2.14.1) and run dart compile exe, it prints:

Could not find /tmp/dart-sdk/bin/snapshots/gen_kernel.dart.snapshot. Have you built the full Dart SDK?

I haven't tested on Windows or Mac OS, but I've verified that this doesn't happen on the 64-bit SDK.

Currently, AOT compilation is not supported when targeting 32-bit Intel (only x64, 32-bit ARM and 64-bit ARM architectures are supported). We should probably print a better error message when dart compile exe or dart compile aot-snapshot are used on IA32.

To be clear, dart compile aot-snapshot does work.

@nex3 Are you sure you're using a 32-bit SDK for dart compile aot-snapshot?

On a fresh checkout:

$ tools/build.py -a ia32 -m release create_sdk

$ out/ReleaseIA32/dart-sdk/bin/dart compile exe test_hello.dart 
Could not find /...skipped.../out/ReleaseIA32/dart-sdk/bin/snapshots/gen_kernel.dart.snapshot. Have you built the full Dart SDK?

$ out/ReleaseIA32/dart-sdk/bin/dart compile aot-snapshot test_hello.dart 
Could not find /...skipped.../out/ReleaseIA32/dart-sdk/bin/snapshots/gen_kernel.dart.snapshot. Have you built the full Dart SDK?

$ out/ReleaseIA32/dart-sdk/bin/dart --version
Dart SDK version: 2.15.0-edge.8c9dcc92f594e8e4f7238aa6f41257e320f95454 (be) (Mon Sep 13 18:02:09 2021 +0000) on "linux_ia32"

[nex3]

You're right, I was testing against the wrong SDK.

[nex3]

This is still an issue. See for example this build, where the failure message is still

Could not find /system/lib/dart/bin/snapshots/gen_kernel_aot.dart.snapshot. Have you built the full Dart SDK?

Fix for the incorrect error message is up for review here. dart compile exe and dart compile aot-snapshot will both continue to be unsupported for the foreseeable future as we don't have AOT support for IA32.
