commit 602b575a88ed4ce12358837daa4d0608a08e03c0 Author: Warner Losh <[email protected]> AuthorDate: 2023-04-21 05:05:30 +0000 Commit: Warner Losh <[email protected]> CommitDate: 2023-04-21 05:39:23 +0000 syscall.master: Remove stray 4.2 Back in 4.3BSD, the system call table wasn't generated, and there was an entry: "4.2 sigreturn", /* 139 = old 4.2 sigreturn */ This got converted to 139 OBSOL 0 4.2 sigreturn in 4.3 RENO. Since it was obsolete, nothing bad happened. In fact, there was code in makeyscalls.sh to cope: { comment = $4 for (i = 5; i <= NF; i++) comment = comment " " $i if (NF < 5) $5 = $4 } so the generated comment in syscalls.c was almost correct: "obs_4.2", /* 139 = obsolete 4.2 sigreturn */ a bug that we have to this very day, despite makesyscalls.sh being rewritten in lua. However, this historical wart is the only place in our current syscalls.master file where we have an extra field for the 'not generated' class of system calls. Remove the historical wart so that the re-write of makesyscalls.lua can be simpler (so, I hope, qemu's bsd-user can large swathes of code automatically generated too). This should help make things more understandable (changes to simplify makesyscalls.lue aren't quite debugged, so have to wait for another day). There's 3 different obsolete sigreturns (but only 1 that was ever in FreeBSD 2.x and newer).
