One indirect edge may have multiple speculative direct edge, the indirect edge must
be out of the loop after all direct edges are cloned.  Added comments in code.

This seems a bit tricky for me.  ipa-icf runs after ipa-profile, the reason why 
remove <common_target_id, common_target_probability> is they are never used in
later passes during previous discussion.

I added a new variable target_prob to save it in direct edge when calling
make_speculative, since the target_prob is assigned in ipa-profile, so no
need to stream out and in through LTO like speculative_id.

Even though, scaling in ipa-icf with multiple direct edges is more complicate then
single direct edge, need double circulation to find each src to dst edge map and do
scaling one by one. 

BTW, the breaking patch r279373 "Fix merging of common traget info." only mentioned
firefox but doesn't include a testcase, I tried to construct some test
cases, but fail to cover all the circumstance (I just implemented the N:N map yet, 
please refer to the code in below patch.), do you have cases other than firefox to
cover it?  Or how to test it as r279373 required?  As this piece of code is not quite
related to this patch, can we just leave it for future refine?  Thanks :)

Other changes are pasted as below patch. Thank you!

v7:
 1. Remove GTY for summaries, replace ggc vec with auto_vec, remove
    is_empty.  Add comment for speculative_id.
 2. Create and duplicate all speculative direct edge's call summary
    in ipa-fnsummary.c.
 3. ipa_merge_profiles update with target_prob.  target_prob is
    generated in ipa-profile, so no need stream out and in through LTO.
 4. Bootstrap passed and no SPEC2017 regression on power8le.

This patch aims to fix PR69678 caused by PGO indirect call profiling
performance issues.
The bug that profiling data is never working was fixed by Martin's pull
back of topN patches, performance got GEOMEAN ~1% improvement(+24% for
511.povray_r specifically).
Still, currently the default profile only generates SINGLE indirect target
that called more than 75%.  This patch leverages MULTIPLE indirect
targets use in LTO-WPA and LTO-LTRANS stage, as a result, function
specialization, profiling, partial devirtualization, inlining and
cloning could be done successfully based on it.
Performance can get improved from 0.70 sec to 0.38 sec on simple tests.
Details are:
  1.  PGO with topn is enabled by default now, but only one indirect
  target edge will be generated in ipa-profile pass, so add variables to enable
  multiple speculative edges through passes, speculative_id will record the
  direct edge index bind to the indirect edge, indirect_call_targets length
  records how many direct edges owned by the indirect edge, postpone gimple_ic
  to ipa-profile like default as inline pass will decide whether it is benefit
  to transform indirect call.
  2.  Use speculative_id to track and search the reference node matched
  with the direct edge's callee for multiple targets.  Actually, it is the
  caller's responsibility to handle the direct edges mapped to same indirect
  edge.  speculative_call_info will return one of the direct edge specified,
  this will leverage current IPA edge process framework mostly.
  3.  Enable LTO WPA/LTRANS stage multiple indirect call targets analysis for
  profile full support in ipa passes and cgraph_edge functions.  speculative_id
  can be set by make_speculative id when multiple targets are binded to
  one indirect edge, and cloned if new edge is cloned.  speculative_id
  is streamed out and stream int by lto like lto_stmt_uid.
  4.  Add 1 in module testcase and 2 cross module testcases.
  5.  Bootstrap and regression test passed on Power8-LE.  No function
  and performance regression for SPEC2017.

There is also merging done from lto-symtab.  If you have COMDAT inline
which is late inlined at -fprofile-generate time you will end up with
multiple profiles for it and they needs to be merged.  This is done
before IPA passes including ipa-profile.

You need testcase with a comdat that is used & inlined in two units,
contains indirect call and build with -fno-early-inlining.

However we can handle this incrementally.

OK. You will need to do the obvious updates for Martin's patch
which turned some member functions into static functions.

Thanks a lot!  Rebased & updated, will commit below patch shortly when git push is ready.


v8:
 1. Rebase to master with Martin's static function (r280043) comments merge.
    Boostrap/testsuite/SPEC2017 tested pass on Power8-LE.
 2. TODO:
    2.1. C++ devirt for multiple speculative call targets.
    2.2. ipa-icf ipa_merge_profiles refine with COMDAT inline testcase.


This patch aims to fix PR69678 caused by PGO indirect call profiling
performance issues.
The bug that profiling data is never working was fixed by Martin's pull
back of topN patches, performance got GEOMEAN ~1% improvement(+24% for
511.povray_r specifically).
Still, currently the default profile only generates SINGLE indirect target
that called more than 75%.  This patch leverages MULTIPLE indirect
targets use in LTO-WPA and LTO-LTRANS stage, as a result, function
specialization, profiling, partial devirtualization, inlining and
cloning could be done successfully based on it.
Performance can get improved from 0.70 sec to 0.38 sec on simple tests.
Details are:
  1.  PGO with topn is enabled by default now, but only one indirect
  target edge will be generated in ipa-profile pass, so add variables to enable
  multiple speculative edges through passes, speculative_id will record the
  direct edge index bind to the indirect edge, indirect_call_targets length
  records how many direct edges owned by the indirect edge, postpone gimple_ic
  to ipa-profile like default as inline pass will decide whether it is benefit
  to transform indirect call.
  2.  Use speculative_id to track and search the reference node matched
  with the direct edge's callee for multiple targets.  Actually, it is the
  caller's responsibility to handle the direct edges mapped to same indirect
  edge.  speculative_call_info will return one of the direct edge specified,
  this will leverage current IPA edge process framework mostly.
  3.  Enable LTO WPA/LTRANS stage multiple indirect call targets analysis for
  profile full support in ipa passes and cgraph_edge functions.  speculative_id
  can be set by make_speculative id when multiple targets are binded to
  one indirect edge, and cloned if new edge is cloned.  speculative_id
  is streamed out and stream int by lto like lto_stmt_uid.
  4.  Create and duplicate all speculative direct edge's call summary
  in ipa-fnsummary.c with auto_vec.
  5.  Add 1 in module testcase and 2 cross module testcases.
  6.  Bootstrap and regression test passed on Power8-LE.  No function
  and performance regression for SPEC2017.

Hello.

I'm pretty sure the patch contains failure of the following tests:

FAIL: gcc.dg/tree-prof/crossmodule-indir-call-topn-1.c scan-pgo-wpa-ipa-dump profile_estimate "2 \\(200.00%\\) speculations produced."
FAIL: gcc.dg/tree-prof/crossmodule-indir-call-topn-2.c scan-pgo-wpa-ipa-dump profile_estimate "2 \\(200.00%\\) speculations produced."
FAIL: gcc.dg/tree-prof/crossmodule-indircall-1.c execution,    -fprofile-use -D_PROFILE_USE

Can you please take a look?
Thanks,
Martin

Thanks for reporting.
This seems fails only on some platforms.  I tested it before commit and
just verified it again on my Power8-LE with gcc.sum andd log attached. 
I suppose you are trying on x86 platforms and sorry that I don't have one
at hand, these failures should be easy to fix, If not, I will investigate
it after returning from Chinese New Year vacation.

Unfortunately, this assertion is failing for most of the testcases in
jit.dg, reducing the number of PASS results in jit.sum from 10473 down
to 3254 in my builds.


Counter-intuitively, "jit" is not in --enable-languages=all (as it also
needs --enable-host-shared at configure time, which slows down the
built compiler code).


The jit code expects to be able to invoke the compiler code more than
once within the same process, purging all state.

It looks like this "call_sums" state needs deleting and resetting to
NULL after the compiler has run (or else we'll likely get an ICE due to
using old symtab/call summaries in subsequent in-process runs of the
compiler).

Is there a natural place to do that within the IPA hooks?  


Alternatively the following patch seems to fix things (not yet fully
tested though); hopefully it seems sane.

gcc/ChangeLog:
        * ipa-profile.c (ipa_profile_c_finalize): New function.
        * toplev.c (toplev::finalize): Call it.
        * toplev.h (ipa_profile_c_finalize): New decl.

Hi.

I know the root cause of the failure and will send a patch soon
to the mailing list.

There's an obvious patch that I'm going to install. Note that
order of function call evaluation in a function call is undefined.
It's a similar issue we had some time ago in IPA VRP streaming.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Thanks,
Martin

David, this may be interesting case for analyzer/warning. This surfaced
in LTO stremaing for second time quite recently and leads to hard to
find bugs. 

While day before yesterday in pub I argued that warning for nested
function calls is not a good way since it would warn too often, perhaps
we want to have some way to annotate streamer functions to make it clear
that we do not want them to appear inside function call parameters where
evaluation order is undefined.

Maybe one can always warn if you call the same function twice (and the
function appears to have side-effects)?  Might fire too often for tree checking
functions tho.

Yep warning always when function calls appear within different
parameters of a function calls seems like something we would not be able
to enable by default...
