From b957a465f65c8eba449a68d5a98f69452ac7eb7e Mon Sep 17 00:00:00 2001 From: Peter Tatrai Date: Mon, 27 Oct 2025 11:29:00 +0100 Subject: [PATCH] oeqa/selftest/rust: strip debug symbols from test binaries Strip debug symbols from test binaries using RUSTFLAGS='-C strip=debuginfo' to reduce binary sizes from 300+ MB to ~140 MB. This is especially critical for PowerPC mac99 which has a hardcoded 768MB RAM limit in QEMU. Without stripping, test binaries uploaded to /tmp (tmpfs) cause 'No space left on device' errors during test execution. The size reduction also benefits all other architectures by reducing memory pressure and upload times during testing.
