The lint target is implemented, but the source tree is not lint-free yet. 322). It is too much of a change to "clean-up" this directory at the time 33 of stand and stand.i386 merge. So, let's use the following rule for 34 the benefit of all. 35 Each time you check in a new version of a file, please try to 36 a). lint that file individually 37 b). cstyle that file 383). Please avoid using the following fragments in the common/ directory 39 #ifdef i386 40 #ifdef sparc 414). The following fragment is non-ideal for the merge (promif) source base 42 #ifdef I386BOOT 43 It should be removed, re-org'ed after a good understanding of the 44 pieces involved and with suitable testing. 455). If you change "common" source files including Makefiles, you have 46 to build [ and test ] for all platforms. 476). The following list should be addressed and eliminated as we continue 48 to separate the PSM code out of shared common (PIM) code 49 a). nfs_readsize for sun4 and i386. 50 b). lib/fs/nfs_inet/netaddr.h: MAX_PKT_SIZE different between i386 and sparc 51 c). lib/fs/nfs_inet/nfsops.c: boot_nfs_read() uses local buffer for i386 case 52 d). all #ifdef sparc caused by prom_getversion() calls 53 54Commonly asked questions and brief answers: 55 56Q: Why is inetboot packaged differently? 57A: inetboot is loaded by PROM code, especially old PROMs. They load 58 to certain specific address and can only recognize a.out header. 59 Thus, inetboot has to be packaged accordingly. Note that the bootblk 60 for sparc has the same constraints. These historical reasons do 61 not apply for i386 architecture. 62
