++ * A qnx4 directory entry is an inode entry or link info |
5430 |
++ * depending on the status field in the last byte. The |
5431 |
++ * first byte is where the name start either way, and a |
5432 |
++ * zero means it's empty. |
5433 |
++ * |
5434 |
++ * Also, due to a bug in gcc, we don't want to use the |
5435 |
++ * real (differently sized) name arrays in the inode and |
5436 |
++ * link entries, but always the 'de_name[]' one in the |
5437 |
++ * fake struct entry. |
5438 |
++ * |
5439 |
++ * See |
5440 |
++ * |
5441 |
++ * https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99578#c6 |
5442 |
++ * |
5443 |
++ * for details, but basically gcc will take the size of the |
5444 |
++ * 'name' array from one of the used union entries randomly. |
5445 |
++ * |
5446 |
++ * This use of 'de_name[]' (48 bytes) avoids the false positive |
5447 |
++ * warnings that would happen if gcc decides to use 'inode.di_name' |
5448 |
++ * (16 bytes) even when the pointer and size were to come from |
5449 |
++ * 'link.dl_name' (48 bytes). |
5450 |
++ * |
5451 |
++ * In all cases the actual name pointer itself is the same, it's |
5452 |
++ * only the gcc internal 'what is the size of this field' logic |
5453 |
++ * that can get confused. |
