Revision 1.38, Tue Dec 7 22:17:02 2021 UTC (2 years, 6 months ago) by guenther
Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, OPENBSD_7_4_BASE, OPENBSD_7_4, OPENBSD_7_3_BASE, OPENBSD_7_3, OPENBSD_7_2_BASE, OPENBSD_7_2, OPENBSD_7_1_BASE, OPENBSD_7_1, HEAD Changes since 1.37: +1 -3 lines
Delete the last emulation callbacks: we're Just ELF, so declare
exec_elf_fixup() and coredump_elf() in <sys/exec_elf.h> and call
them and the MD setregs() directly in kern_exec.c and kern_sig.c
Also delete e_name[] (only used by sysctl), e_errno (unused), and
e_syscallnames[] (only used by SYSCALL_DEBUG) and constipate
syscallnames to 'const char *const[]'
