with respect to syscalls. It is detailed and comprehensive but does not offer a way to deal with minor deviations in behaviour from the vanilla kernel sources, either due to running a hacked kernel or running a vanilla kernel with a custom kernel module loaded. This commit adds a flexible way to handle such cases without polluting the vanilla handler syswrap-*.c files or their supporting vki_*.h header files. For each OS, a syswrap-OS-variants.c file is added, containing wrappers for variants of OS. A new command line flag --kernel-variants= carries a comma separated list of variant names that apply to the current run. There are no other changes. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@4873

/* The files syswrap-generic.c, syswrap-linux.c, syswrap-x86-linux.c,
|
|
syswrap-amd64-linux.c and syswrap-ppc32-linux.c, and associated

vki*.h header files, constitute Valgrind's model of how a vanilla

|
Linux kernel behaves with respect to syscalls.
|
|
|
|
On a few occasions, it is useful to run with a kernel that has some
|
|
(minor) extensions to the vanilla model, either due to running on a
|
|
hacked kernel, or using a vanilla kernel which has incorporated a
|
|
custom kernel module. Rather than clutter the standard model, all
|
|
such variant handlers are placed in here.
|
|
|

Unlike the C files for the standard model, this file should also
|
|
contain all constants/types needed for said wrappers. The vki*.h
|
|
headers should not be polluted with non-vanilla info. */
