There are extensions to x86-64 psABI: https://groups.google.com/forum/#!topic/x86-64-abi/de5_KnLHxtI and i386 psABI: https://groups.google.com/forum/#!topic/ia32-abi/awsRSvJOJfs to call tls_get_addr via GOT. X86 assembler and linker in binutils 2.27 implemented call *__tls_get_addr@GOTPCREL(%rip) in 64-bit and call *___tls_get_addr@GOT(%reg) in 32-bit to access global and local thread loal variables in shared library. We check if 32-bit x86 assembler and linker work with call *___tls_get_addr@GOT(%reg) as 32-bit and 64-bit assembler and linker are enabled togther. In 32-bit, since any integer register except EAX, which is used to pass parameter to ___tls_get_addr, and ESP, can be used as GOT base, a new register class, TLS_GOTBASE_REGS, along with a new constraint, Yb, are added.

Add support for profiledbootstrap with autofdo. Will be useful to get better testing coverage of autofdo. This requires Linux perf and autofdo to be installed, only really for x86_64 linux on Intel so far. Profile the whole build process with perf, then convert the file, and pass it back to the compiler in the feedback stage. The conversion has to be done per language, as only that knows the name of the binary. Currently we only do it for C and C++, as the other languages don't have enough coverage during a normal bootstrap. For lto1 it is also disabled, because it would only be useful during a LTO bootstrap, but right now autofdo and LTO are not working together due to PR66229 For common backend files always the profile output of the C++ compiler is used. In theory multiple inputs could be merged here, but so far that is not implemented. The method is not friendly to partial rebuilds, as only the profile information from the current rebuild is used. So if an error occurs it is best to clean and restart, otherwise the code quality may be worse. This patch is fairly large, but most of it is auto generated from autogen in Makefile.in. for the new stage targets. Passes profiledbootstrap and normal bootstrap on x86_64-linux. autoprofiledbootstrap is currently not working due to PR70427 (but it finishes with that worked around) The autofdo'ed compiler is ~7% faster on insn-recog.i (vs ~11% for profiledfeedback), and ~4% faster for tramp3d-v4 (vs 10% for profiledfeedback) on a Sandy Bridge system. gcc/lto/: 2016-06-23 Andi Kleen <ak@linux.intel.com> * Make-lang.in: Add support for autofdo (disabled for now) gcc/cp/: 2016-06-23 Andi Kleen <ak@linux.intel.com> * Make-lang.in: Add support for autofdo. gcc/: 2016-06-23 Andi Kleen <ak@linux.intel.com> * Makefile.in: Regenerate. * doc/install.texi: Document autoprofiledbootstrap. /: 2016-06-23 Andi Kleen <ak@linux.intel.com> * Makefile.def: Add autoprofiledbootstrap. * Makefile.tpl: Dito. * Makefile.in: Regenerate. gcc/c/: 2016-06-23 Andi Kleen <ak@linux.intel.com> * Make-lang.in: Add support for autofdo.
