Eugene Rozenfeld ba125745d9 AutoFDO: Don't try to promote indirect calls that result in recursive direct calls
AutoFDO tries to promote and inline all indirect calls that were promoted
and inlined in the original binary and that are still hot. In the included
test case, the promotion results in a direct call that is a recursive call.
inline_call and optimize_inline_calls can't handle recursive calls at this stage.
Currently, inline_call fails with a segmentation fault.

This change leaves the indirect call alone if promotion will result in a recursive call.

Tested on x86_64-pc-linux-gnu.

gcc/ChangeLog:
	* auto-profile.cc (afdo_indirect_call): Don't attempt to promote indirect calls
	that will result in direct recursive calls.

gcc/testsuite/ChangeLog:
	* g++.dg/tree-prof/indir-call-recursive-inlining.C : New test.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
