shuffle bits around. separate conversion conversion functions and tables from the code that uses them, just as I previously separated out the OSF/1 definitions and structures from the code that translates to and from them. 1999-05-01 06:57:08 +04:00			`#include <compat/osf1/osf1_cvt.h>`
do special OSF/1-specific ECOFF recognition (not yet complete), and implement a copyargs function to do special argument copying for emulated processes. 1999-04-27 05:45:03 +04:00

restructure struct emul and execsw, in preparation to make emulations LKMable: * move all exec-type specific information from struct emul to execsw[] and provide single struct emul per emulation * elf: - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry per emulation and contains pointer to respective probe function - interp is allocated via MALLOC() rather than on stack - elf_args structure is allocated via MALLOC() rather than malloc() * ecoff: the per-emulation hooks moved from alpha and mips specific code to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per emulation supporting ecoff with appropriate probe function * the makecmds/probe functions don't set emulation, pointer to emulation is part of appropriate execsw[] entry * constify couple of structures 2000-11-21 03:37:49 +03:00			`const struct emul emul_osf1 = {`

add e_path (emulation path) to struct emul, which replaces emulation-specific _emul_path variables change macros CHECK_ALT_{CREAT\|EXIST} to use that, 'root' doesn't need to be passed explicitly any more and _CHECK_ALT_{CREAT\|EXIST} are removed change explicit emul_find() calls in probe functions to get the emulation path from the checked exec switch entry's emulation remove no longer needed header files add e_flags and e_syscall to struct emul; these are unsed and empty for now 2000-12-01 15:28:30 +03:00			`"/emul/osf1",`

Introduce 2 new flags in types.h: * __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by e_syscall_intern, which is called at key places in the kernel. This can be used to set a MD syscall handler pointer. This obsoletes and replaces the _HAS_SEPARATED_SYSCALL flags. __HAVE_MINIMAL_EMUL.
