33 | // !!! For a structure with a series of bit fields and used as a storage in vfr file, and if the bit fields do not add up to the size of the defined type.\r | |
34 | // In the C code use sizeof() to get the size the strucure, the results may vary form the compiler(VS,GCC...).\r | |
35 | // But the size of the storage calculated by VfrCompiler is fixed (calculate with alignment).\r | |
36 | // To avoid above case, we need to make the total bit width in the structure aligned with the size of the defined type for these bit fields. We can:\r | |
37 | // 1. Add bit field (with/without name) with remianing with for padding.\r | |
38 | // 2. Add unnamed bit field with 0 for padding, the amount of padding is determined by the alignment characteristics of the members of the structure.\r | |
