Thus elsewhere in the code a ``b(INNER1)`` -will cause execution to continue with the instruction after the label directive. - -Defining inline data --------------------- - -The following assembler directives facilitate embedding data in an assembler code block. - -* data(size, d0, d1 .. dn) - -The data directive creates n array of data values in memory. The first argument specifies the -size in bytes of the subsequent arguments. Hence the first statement below will cause the -assembler to put three bytes (with values 2, 3 and 4) into consecutive memory locations -while the second will cause it to emit two four byte words. - -:: - - data(1, 2, 3, 4) - data(4, 2, 100000) - -Data values longer than a single byte are stored in memory in little-endian format. - -* align(nBytes) - -Align the following instruction to an nBytes value. ARM Thumb-2 instructions must be two -byte aligned, hence it's advisable to issue ``align(2)`` after ``data`` directives and -prior to any subsequent code. This ensures that the code will run irrespective of the -size of the data array. |
