Add a contrib script for comparing the performance of two sets of
compiler runs.

Usage documentation is in the script.

The script produces output of the form:

$ compare_two_ftime_report_sets "Log0/*perf" "Log3/*perf"

Arithmetic sample for timevar log files
"Log0/*perf"
and selecting lines containing "TOTAL" with desired confidence 95 is
trial count is 4, mean is 443.022 (95% confidence in 440.234 to 445.811),
std.deviation is 1.75264, std.error is 0.876322

Arithmetic sample for timevar log files
"Log3/*perf"
and selecting lines containing "TOTAL" with desired confidence 95 is
trial count is 4, mean is 441.302 (95% confidence in 436.671 to 445.934),
std.deviation is 2.91098, std.error is 1.45549

The first sample appears to be 0.39% larger,
with 60% confidence of being larger.
To reach 95% confidence, you need roughly 14 trials,
assuming the standard deviation is stable, which is iffy.

Tested on x86_64 builds.

Function Multiversioning
========================

Sriraman Tallam, tmsriram@google.com

Overview of the patch which adds support to specify function versions.  This is
only enabled for target i386.

Example:

int foo ();  /* Default version */
int foo () __attribute__ ((target("avx,popcnt")));/*Specialized for avx and popcnt */
int foo () __attribute__ ((target("arch=core2,ssse3")));/*Specialized for core2 and ssse3*/

int main ()
{
 int (*p)() = &foo;
 return foo () + (*p)();
}

int foo ()
{
 return 0;
}

int __attribute__ ((target("avx,popcnt")))
foo ()
{
 return 0;
}

int __attribute__ ((target("arch=core2,ssse3")))
foo ()
{
 return 0;
}

The above example has foo defined 3 times, but all 3 definitions of foo are
different versions of the same function. The call to foo in main, directly and
via a pointer, are calls to the multi-versioned function foo which is dispatched
to the right foo at run-time.

Front-end changes:

The front-end changes are calls at appropriate places to target hooks that
determine the following:

* Determine if two function decls with the same signature are versions.
* Determine the assembler name of a function version.
* Generate the dispatcher function for a set of function versions.
* Compare versions to see if one has a higher priority over the other.

All the implementation happens in the target-specific config/i386/i386.c.

What does the patch do?

* Tracking decls that correspond to function versions of function
name, say "foo":

When the front-end sees more than one decl for "foo", it calls a target hook to
determine if they are versions. To prevent duplicate definition errors with
other versions of "foo", "decls_match" function in cp/decl.c is made to return
false when 2 decls have are deemed versions by the target. This will make all
function versions of "foo" to be added to the overload list of "foo".

* Change the assembler names of the function versions.

For i386, the target changes the assembler names of the function versions by
 suffixing the sorted list of args to "target" to the function name of "foo".
For example, the assembler name of
 "void foo () __attribute__ ((target ("sse4")))" will
become _Z3foov.sse4.  The target hook mangle_decl_assembler_name is used
for this.

* Overload resolution:

 Function "build_over_call" in cp/call.c sees a call to function
"foo", which is multi-versioned. The overload resolution happens in
function "joust" in "cp/call.c". Here, the call to "foo" has all
possible versions of "foo" as candidates. All the candidates of "foo" are
stored in the cgraph side data structure. Each version of foo is chained in a
doubly-linked list with the default function as the first element.  This allows
any pass to access all the semantically identical versions. A call to a
multi-versioned function will be replaced by a call to a dispatcher function,
determined by a target hook, to execute the right function version at run-time.

Optimization to directly call a version when possible:
Also, in joust, where overload resolution happens, a multiversioned function
resolution is made to return the most specialized version.  This is the version
that will be checked for dispatching first and is determined by the target.
Now, if the caller can inline this function version then a direct call is made
to this function version rather than go through the dispatcher. When a direct
call cannot be made, a call to the dispatcher function is created.

* Creating the dispatcher body.

The dispatcher body, called the resolver is made only when there is a call to a
multiversioned function dispatcher or the address of a function is taken. This
is generated during cgraph_analyze_function. This is done by another target hook.

* Dispatch ordering.

The order in which the function versions are checked during dispatch is based
on a priority value assigned for the ISA that is catered. More specialized
versions are checked for dispatching first.  This is to mitigate the ambiguity
that can arise when more than one function version is valid for execution on
a particular platform.  This is not a perfect solution, and in future the user
should be allowed to assign a dispatching priority value to each version.

Function MV in the Intel compiler:

The intel compiler supports function multiversioning and the syntax is
similar to the patch proposed here.  Here is an example of how to
generate multiple function versions with the intel compiler.

/* Create a stub function to specify the various versions of function that
   will be created, using declspec attribute cpu_dispatch.  */
__declspec (cpu_dispatch (core_i7_sse4_2, atom, generic))
void foo () {};

/* Bodies of each function version.  */

/* Intel Corei7 processor + SSE4.2 version.  */
__declspec (cpu_specific(core_i7_sse4_2))
void foo ()
{
  printf ("corei7 + sse4.2");
}

/* Atom processor.  */
__declspec (cpu_specific(atom))
void foo ()
{
  printf ("atom");
}

/* The generic or the default version.  */
__declspec (cpu_specific(generic))
void foo ()
{
  printf ("This is generic");
}

A new function version is generated by defining a new function with the same
signature but with a different cpu_specific declspec attribute string.  The
set of cpu_specific strings that are allowed is the following:

"core_2nd_gen_avx"
"core_aes_pclmulqdq"
"core_i7_sse4_2"
"core_2_duo_sse4_1"
"core_2_duo_ssse3"
"atom"
"pentium_4_sse3"
"pentium_4"
"pentium_m"
"pentium_iii"
"generic"

Comparison with the GCC MV implementation in this patch:

* Version creation syntax:

The implementation in this patch also has a similar syntax to specify function
versions. The first stub function is not needed.  Here is the code to generate
the function versions with this patch:

/* Intel Corei7 processor + SSE4.2 version.  */
__attribute__ ((target ("arch=corei7, sse4.2")))
void foo ()
{
  printf ("corei7 + sse4.2");
}

/* Atom processor.  */
__attribute__ ((target ("arch=atom")))
void foo ()
{
  printf ("atom");
}

void foo ()
{
}

The target attribute can have one of the following arch names:

"amd"
"intel"
"atom"
"core2"
"corei7"
"nehalem"
"westmere"
"sandybridge"
"amdfam10h"
"barcelona"
"shanghai"
"istanbul"
"amdfam15h"
"bdver1"
"bdver2"

and any number of the following ISA names:

"cmov"
"mmx"
"popcnt"
"sse"
"sse2"
"sse3"
"ssse3"
"sse4.1"
"sse4.2"
"avx"
"avx2"
