5dca1b261b dyxlat: new interface for building xlat tables dynamically
xlat tables are usually generated at build time.

printxval is suitable for printing struct nlmsghdr.nlmsg_type for
NETLINK_GENERIC protocol.  However, the corresponding xlat table
cannot be defined at build time because the values are registered
by the kernel at run time.

This change introduces dyxlat functions for building xlat tables
dynamically.  The primary use case is decoding nlmsg_type but this
interface can be used for other purposes.

* defs.h (struct dyxlat): New opaque data type.
(dyxlat_alloc, dyxlat_free, dyxlat_add_pair): New function declarations.
* dyxlat.c: New file.
* Makefile.am (strace_SOURCES): Add it.

a3da3c32c1 Makefile.am: don't confuse CFLAGS and CFLAGS_FOR_BUILD
Commit dc427d50d9 enabled a number of extra
warning flags through configure.ac.  The configure script will determine
dynamically if CC supports these flags before adding them to WARN_CFLAGS.

ioctlsort is compiled with CC_FOR_BUILD, rather than CC.  Nevertheless,
the flags passed to this compilation also include WARN_CFLAGS (through
AM_CFLAGS).  This is incorrect: in a cross-compilation use case, CC
and CC_FOR_BUILD are not the same.  The former is the cross-compiler,
the latter is the host compiler.  Both may be of different versions
and support different warning flags.

In particular, this posed a problem when cross-compiling with a host
compiler gcc 4.1, which does not support all the new flags:

    /usr/bin/gcc -DHAVE_CONFIG_H   -I./linux/arm -I./linux/arm -I./linux
    -I./linux -I. -I. -I/host-sysroot/usr/include -Wall -Wempty-body

Do not assume that some syscalls do not generate syscall-exit-stops.

a8fce09e34 mpers: add support of conditionally compiled printers
We used to declare and define all printers marked with
MPERS_PRINTER_DECL, including ifdef'ed ones.  That approach left us
no way to conditionally compile mpersified printers, which was not
a problem until btrfs ioctls appeared on the horizon.

With this change, those mpersified printers that are not going
to be compiled are also won't be declared and won't be added to
struct_printers.

This is implemented by filtering all source files containing
MPERS_PRINTER_DECL markers through CPP.  As a nice side effect, this
also lifts an ugly requirement of writing all MPERS_PRINTER_DECL
declarations in a single line.

* README-mpers: Update description of MPERS_PRINTER_DECL syntax.
* defs.h [IN_MPERS_BOOTSTRAP] (MPERS_PRINTER_DECL): Turn into
a recursive variadic macro.
[!IN_MPERS_BOOTSTRAP] (MPERS_PRINTER_DECL): Turn into a variadic macro.

Before this change, all files that exist since 20th century had

It doesn't mean that copyright headers became maintained.  In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.

have ARCH_PC_PEEK_ADDR defined there, and the common code in syscall.c

5cb45b25a3 mpers: skip xlat struct definitions in mpers mode
Avoid duplicate definitions of xlat structures in files
compiled in mpers mode.

Each xlat file defines the corresponding xlat struct with
either global or local visibility using the following rules:

- if xlat struct declaration is available in defs.h,
  a global definition is provided in regular mode,
  and nothing is provided in mpers mode;
- otherwise, if xlat file is included by a mpers source file,
  a global definition is provided in regular mode
  (unless no mpers mode is supported on this architecture,
  in that case, a local definition is provided instead),
  and a declaration is provided in mpers mode;
- otherwise, a local definition is provided in regular mode,
  and an error message is printed in mpers mode.

Fallback definitions of constants provided by xlat files
remain available in all modes.

* bootstrap: Invoke generate_mpers_am.sh before xlat/gen.sh.
* defs.h (adjtimex_modes, adjtimex_status, sigev_value): Remove.
* generate_mpers_am.sh: Generate mpers_xlat.h.
* Makefile.am (EXTRA_DIST): Add mpers_xlat.h.
* print_sigevent.c: Include "xlat/sigev_value.h" unconditionally.
* print_timex.c: Include "xlat/adjtimex_modes.h" and
"xlat/adjtimex_status.h" unconditionally.

(gen_header): Check also mpers_xlat.h for global declarations
of xlat structures.
Process input file twice, first time print directives
only, second time print everything.
Wrap struct xlat into #ifdef IN_MPERS ... #else ... #endif.
* xlat/getrandom_flags.in: Cleanup.

ad25c74f4b Fix make -j builds
In files generated by mpers scripts, includes directives are taken from
original files where the type definition was done.  This causes to
include defs.h in multiple files.  defs.h includes printers.h header,
which is a generated header.

This patch add an explicit dependency to printers.h for the mpers
scripts.

* Makefile.am (mpers-m%.stamp): Add printers.h to order-only

092942206c Add mpers support
Add a subsystem for semi-automatical definition of how parsers should
work with personality-dependent (mpers) types of tracee's data.  Create
auxiliary libraries containing mpers syscall parsers and printer
functions, one library for each possible nonnative target personality.

Currently some parsers do not handle differences in definitions of data
types between personalities, namely LP64 and ILP32.  When
this is the case, long integers, pointers, and all compound
types containing long and pointer members may be printed incorrectly,
because of differences in sizes, offsets and alignments.

Since in most cases these are the only differences in desired behaviour
of parsers and printers for different personalities, a correct way
would be to compile one source code into multiple parsers, differing
only in definitions of mpers types.

To get a definition of a given type for nonnative personality
a very basic .c file containing a declaration of a variable of this type
is being compiled for this personality (using -m32 or -mx32 compiler
flag).  Information about the type is then being extracted from
this binary's DWARF debug info with an awk script and put
into a corresponding header file.  Resulting headers are being used to
compile mpers variations of syscall parsers and printer functions.

In addition to syscall parsers, there can occur a need to create mpers
printing functions, which then can be called from many places
in the code (for example, printsiginfo_at).  Such functions (printers)
are marked in a special manner.

For each possible nonnative target personality a library is being
created, containing mpers variations of syscall parsers and printers.
Only syscall parsers from files marked in a special manner and specially
marked functions from such files are being recompiled and included
in these libraries.

generate_mpers_am.sh is called by bootstrap to find the files
from strace_SOURCES which include MPERS_DEFS.  During compilation,
these files are being inspected for inclusions of DEF_MPERS_TYPE,
and nonnative variations of each included type are being generated
by an awk script.

Mpers parser names are being modified during inclusions of syscallent
headers for nonnative personalities.  Pointers to printers are
being stored in structs struct_printers, and a master
pointer printers is being updated on every set_personality.

bd8dd776db Add support for Altera's Nios-II softcore architecture
This commit adds strace support for Altera's Nios-II.  The architecture
is supported by Linux since v3.19, and it implements the generic syscall
ABI.

* configure.ac: Add nios2 support.
* cacheflush.c [NIOS2] (sys_cacheflush): New function.
* linux/nios2/*: New Nios-II specific files.
* Makefile.am (EXTRA_DIST): Add them.

df4dd8b540 sparc: delete personality 1
Personality 1 for sparc and sparc64 appears to be an old attempt
to support stracing Solaris binaries.

It stalled after the only syscall, solaris_open, was covered:
all other solaris_foo's are printargs.

This change deletes personality 1. Now sparc is an one-personality
arch, and sparc64 is a two-personality one.

For clarity, pure renaming of personality 2 files to personality 1 for sparc64
is performed in the next commit - this prevents a state where syscallent1.h
seems to indergo a lot of changes, where in fact in is deleted, and then
replaced by syscallent2.h

Therefore, tree at this commit will not build.
