AGB ABI Library (agbabi)

Quick Start Guide

Link with libagbabi.a via the normal means for your build environment (eg: -Lagbabi for GCC and Clang), and add the include directory via the normal means for your build environment (eg: -Iagbabi/include).

Linking will implicitly activate the armeabi library.

Include the armeabi.h and agbabi.h headers to access the armeabi and agbabi C functions.

#include <aeabi.h>
#include <agbabi.h>
#include <sys/ucontext.h> /* POSIX context switching */

int main() {

    unsigned int a = __aeabi_uidiv(9u, 3u);

    int b = __agbabi_sqrt(25u);

    ucontext_t c;
    getcontext(&c);

    return 0;
}
