CVS commit: src/sys/lib/libsa

Module Name:    src
Committed By:   rin
Date:           Wed Apr 27 11:48:26 UTC 2022

Modified Files:
        src/sys/lib/libsa: ext2fs.c minixfs3.c stand.h ufs.c

Log Message:
Introduce SA_HARDCODED_SECSIZE hack, by which hardcoded DEV_BSIZE is
used instead of secsize obtained by SAIOSECSIZE ioctl.

This hack avoids divdi3 and friends from being linked, in order to
support variable secsize.

This is useful for amiga/boot(8); it is loaded by firmware into
unpredictable address, and therefore all symbols should be
addressable by PC relative mode with only 16-bit displacements.

See sys/arch/amiga/stand/bootblock/{boot/bbstart.s,elf2bb,txlt} for
more details.
