commit 5c372814961ae0db9c68a667827b626fd948aa42 Author: Kito Cheng <[email protected]> Date: Fri Aug 8 09:00:59 2025 +0800 Increase NUM_ABI_IDS to support RISC-V VLS calling convention variants The RISC-V fixed-length vector calling convention introduces multiple ABI variants based on different ABI_VLEN values. Each variant requires a separate ABI ID to maintain proper ABI compatibility tracking in GCC. Increase NUM_ABI_IDS from 8 to 12 to accommodate these additional ABI variants. gcc/ChangeLog: * function-abi.h (NUM_ABI_IDS): Increase from 8 to 12.
