2.7 EABI Standard
Embedded application binary interface (EABI) is a set of software conventions. They span areas such
as register usage, stack layout and parameter passing. Examples of EABI conventions are dedicating
register r1 the stack pointer, organizing the stack in frames, and assigning certain general-purpose reg-
isters (gprs) and floating point registers (fprs) as volatile and nonvolatile among function calls. Compiler
and debug tool vendors have adopted EABI conventions for interoperability. Refer to the
Embedded
Application Environments Interface,
