ARM Compiler armlink User Guide : --bpabi


Creates a Base Platform Application Binary Interface (BPABI) ELF file for passing to a platform-specific post-linker.


Not supported for AArch64 state.


The BPABI model defines a standard-memory model that enables interoperability of BPABI-compliant files across toolchains. When you specify this option:

  • Procedure Linkage Table (PLT) and Global Offset Table (GOT) generation is supported.

  • The default value of the --pltgot option is direct.

  • dynamically linked library (DLL) placed on the command-line can define symbols.


The BPAPI model does not support scatter-loading. However, scatter-loading is supported in the Base Platform model.

Weak references in the dynamic symbol table are permitted only if the symbol is defined by a DLL placed on the command-line. You cannot place an unresolved weak reference in the dynamic symbol table with the IMPORT steering file command.
