I would like to request an official build of the language_server_linux_arm binary that targets a generic AArch64 baseline (ARMv8.0), to support a wider range of ARM servers.
I am attempting to run the Antigravity on an ARMv8.2-A based server environment. However, the current language server binary crashes immediately upon startup.
FATAL ERROR: This binary was compiled with rcpc enabled, but this feature is not available on this processor (go/sigill-fail-fast).
By analyzing the crash dump with GDB, I identified that the instruction causing the crash is LDAPRB (Load-Acquire RCpc Byte).
=> 0x.......: ldaprb w8, [x8]
This instruction belongs to the ARMv8.3 RCPC extension. While newer chips (like Graviton 3 or Apple Silicon) support this, many widely deployed enterprise ARM processors (such as those based on the Neoverse N1 core, e.g., AWS Graviton 2 and others) are strictly ARMv8.2 and do not implement RCPC.
Please consider adding a “Compatibility Build” to your release pipeline.
