[PATCH v9 15/19] ld tests for AArch64-specific merge coverage for AEABI Build Attributes
Matthieu Longo
matthieu.longo@arm.com
Mon Sep 1 16:56:22 GMT 2025
Test cases:
- coverage of required subsection 'aeabi_pauthabi'.
- coverage for BTI, PAC, GCS used along GNU properties.
- warn on unknown attributes, and prune them from output.
