I tried using 'svn merge' to do the merge but it did a terrible job and there were bazillions of conflicts. So instead I just took the diff between the branch and trunk at r10155, applied the diff to the trunk, 'svn add'ed the added files (no files needed to be 'svn remove'd) and committed. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10156

/* This file defines the system call numbers.
|
|
|
|
On Linux they are a bunch of #define'd constants of the form
|
|
__NR_name, and this file must contain nothing else, since it will
|
|
be included in assembly code (m_trampoline.S).
|
|
|
|
On AIX the __NR_name consts are renamings of global variables which
|
|
tell us the number for each syscall. This elaboration is necessary
|
|
because on AIX the syscall numbers are not constant; they can be
|
|
different for each process (in principle; in practice they rarely
|
|
change). 32- and 64-bit AIX5 share a common "implementation".
|
|
|
|
On Darwin the __NR_name consts are #define'd constants which are
|
|
computed using various macros. 32- and 64-bit Darwin share a common
|
|
"implementation" also.
|
|
|
|
This file is merely a top-level "steering" file, which pulls in the
|
|
correct bits for the relevant platform. You should not directly
|
|
#include any file in include/vki; instead #include only this one or
|
|
pub_core_vkiscnums.h.
