A small utility for decoding aarch64 ESR register values.
This is not an officially supported Google product.
Install a Debian package from the
latest release, install with
cargo install aarch64-esr-decoder, or
try the web version.
For the command-line version, just pass the ESR value you're interested in as a parameter, in decimal or hexadecimal:
``` $ aarch64-esr-decoder 0x96000050 ESR 0x00000000000000000000000096000050:
