- Introduced VG_SYSNUM_STRING and VG_SYSNUM_STRING_EXTRA which factor out differences in the way syscall numbers are printed on different platforms. This gets rid of seven "DDD" fixme-style comments. - This also meant that Darwin syscall numbers are now printed in a non-ambiguous way -- previously Unix, machine-dependent and diagnostic syscalls were all printed the same way, even though their numbers overlap. Now each number is prefixed with "unix", "mdep", etc. And Mach trap numbers aren't printed as negative numbers now that they have a "mach" prefix. - Split each of pub_core_vkiscnums.h and pub_tool_vkiscnums.h into two parts, one suitable for inclusion in asm files, one suitable for inclusion in C files; in both cases the latter includes the former. This makes this module more like other modules that have asm-only components (eg. m_transtab); it also allows the hacky VG_IN_ASSEMBLY_SOURCE macros and tests to be removed. - Removed some of the VG_DARWIN_SYSNO_* macros that were no longer needed, and renamed some of the existing ones to make their meanings clearer. - Added comments on the encoding of Darwin syscall numbers so it's possible for mortals to understand without reading the kernel code.. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10218

//--------------------------------------------------------------------
|
|
// PURPOSE: This module holds all the syscall numbers, and a handful of
|
|
// operations relating to them.
|
|
//
|
|
// 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
|
|
// encoded using various macros. 32- and 64-bit Darwin share a common
|
|
// "implementation" also.
|
|
//
|
|
// Note that most of the actual code for this module is in include/vki/, but
|
|
// you should not directly #include any file in include/vki; instead #include
|
|
// only one of pub_{core,tool}_vkiscnums{,_asm}.h.
