Raw Normal View History

Make a bunch of backward-compatible changes to the boot blocks which allow size to be reduced substantially. (backward compatibility verified by compiling one of the alpha boot blocks which uses all of the code before and after, diffing the object files, and manually verifying that the differences were 'correct'. some differences were "unavoidable," it wanting to avoid a double-commit, because e.g. local variables which were previously used were no longer used.) a README which describes supported options (or at least the ones mentioned below) is forthcoming. add support for the preprocessor macro LIBSA_NO_TWIDDLE, which causes calls to twiddle() to be omitted if it's defined. add support for the preprocessor macros: LIBSA_NO_FS_CLOSE LIBSA_NO_FS_WRITE LIBSA_NO_FS_SEEK which, if defined, cause the corresponding file system operations in the individual file system implementations to be omitted. (note that all of those macros are not supported by all file systems at this point. comments were added to individual file system files to indicate lack of support, and should be cleaned up later. Backward compatibility options e.g. UFS_NOCLOSE, etc., are supported.) add support for the preprocessor macro LIBSA_NO_FS_SYMLINK, which removes support for symbolic links from the file system support functions. (same notes as for the macros above apply.) add support for the preprocessor macro LIBSA_FS_SINGLECOMPONENT which removes all subdirectory and symlink support from the file system support functions. (same notes as for the macros above apply.) add support for the preprocessor macro LIBSA_NO_FD_CHECKING, which causes code relating to libsa file descriptor checks (e.g. range checking and checking that a file descriptor is valid) to be omitted if it's defined. add support for the preprocessor macro LIBSA_NO_RAW_ACCESS, which causes code relating to raw device access to be omitted if it's defined. change some structure copies to use bcopy() instead. that way use of bcopy vs. memcpy() can easily be selected by LIBSA_USE_MEMCPY. (without changes like these, you could end up having both bcopy() and memcpy() included. eventually, all calls to bcopy should be changed to calls to memcpy() or memmove() as appropriate -- hopefully never the latter -- with an option to use bcopy instead.) add support for the preprocessor macro LIBSA_NO_DISKLABEL_MSGS, which causes disklabel() to return '1' as msg rather than a string. Can be used if the boot blocks don't care about the string, and need to save the space. add support for the preprocessor macro LIBSA_SINGLE_FILESYSTEM, which if defined causes all of the file system switch code to be removed. Its value should be the name of the file system supported by the boot block, e.g. "ufs" for the FFS file system. calls to the file system functions open, close, etc., which were previously done through a function switch are then done via direct invocation of <fs>_open, <fs>_close, etc. (e.g. ufs_open, ...). add support for the preprocessor macro LIBSA_SINGLE_DEVICE, which does the equivalent of LIBSA_SINGLE_FILESYSTEM but for the device switch table. Device entry pointes are expected to be named <dev>foo, e.g. the 'strategy' routine used when LIBSA_SINGLE_DEVICE is set to 'disk' is diskstrategy. make ufs.c f_nindir array be unsigned ints. the fact that it was signed caused ufs.c to require signed division routines (which were otherwise unnecessary for a small boot block).

__dead void panic __P((const char *, ...)) __attribute__((noreturn));
Some files containing more than one function are split. This reduces the size of the resulting loader. The read_inode() function now returns the result of the strategy function instead of success in all cases (ufs.c). Fixes pr#1817

__dead void _rtt __P((void)) __attribute__((noreturn));
Another round of clean up, including fixes presented by Matthias Drochner (PR#1404).
