To place C library code, specify the library path and library name as the module selector. You can use wildcard characters if required. For example:

LR1 0x0
{
    ROM1 0
    {
        * (InRoot$$Sections)
        * (+RO)
    }
    ROM2 0x1000
    {
        *armlib/c_* (+RO)                   ; all Arm-supplied C library functions
    }
    RAM1 0x3000
    {
        *armlib* (+RO)                      ; all other Arm-supplied library code
                                            ; for example, floating-point libraries
    }
    RAM2 0x4000
    {
        * (+RW, +ZI)
    }
}

The name armlib indicates the Arm^® C library files that are located in the directory install_directory\lib\armlib.
