2016-06-27The code currently generated for the vpermr is (sometimes/always?) wrong inibm/fixvpermrKelvin Nilsen
that the two register inputs are swapped. The translation of gcc-torture/execute/sxcal-to-vec1.c emits vpermr v0,v0,v1,v13 when it should instead emit vpermr v0,v1,v0,v13. This branch provides a worspace to address this problem. git-svn-id: https://gcc.gnu.org/svn/gcc/branches/ibm/fixvpermr@237799 138bc75d-0d04-0410-961f-82ee72b054a4

2016-06-24Call tls_get_addr via GOT for GNU TLS if possibleH.J. Lu
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. They are used to improve register allocation for 32-bit dynamic TLS patterns. gcc/ * configure.ac (calling ___tls_get_addr via GOT): New assembler/linker check. (HAVE_AS_IX86_TLS_GET_ADDR_GOT): New.

2016-06-23Add make autoprofiledbootstrapAndi Kleen
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. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@237733 138bc75d-0d04-0410-961f-82ee72b054a4
2016-06-23Run profile feedback tests with autofdoAndi Kleen
Extend the existing bprob and tree-prof tests to also run with autofdo. The test runtimes are really a bit too short for autofdo, but it's a reasonable sanity check. This only works natively for now. dejagnu doesn't seem to support a wrapper for unix tests, so I had to open code running these tests. That should be ok due to the native run restrictions. gcc/testsuite/: 2016-06-23 Andi Kleen <ak@linux.intel.com> * g++.dg/bprob/bprob.exp: Support autofdo. * g++.dg/tree-prof/tree-prof.exp: dito. * gcc.dg/tree-prof/tree-prof.exp: dito. * gcc.misc-tests/bprob.exp: dito. * gfortran.dg/prof/prof.exp: dito. * lib/profopt.exp: dito. * lib/target-supports.exp: Check for autofdo. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@237732 138bc75d-0d04-0410-961f-82ee72b054a4
2016-06-23Add gcc-auto-profile scriptAndi Kleen
Using autofdo is currently something difficult. It requires using the model specific branches taken event, which differs on different CPUs. The example shown in the manual requires a special patched version of perf that is non standard, and also will likely not work everywhere. This patch adds a new gcc-auto-profile script that figures out the correct event and runs perf. This is needed to actually make use of autofdo in a generic way in the build system and in the test suite. Since maintaining the script would be somewhat tedious (needs changes every time a new CPU comes out) I auto generated it from the online Intel event database. The script to do that is in contrib and can be rerun. Right now there is no test if perf works in configure. This would vary depending on the build and target system, and since it currently doesn't work in virtualization and needs uptodate kernel it may often fail in common distribution build setups. So far the script is not installed. gcc/: 2016-06-23 Andi Kleen <ak@linux.intel.com> * config/i386/gcc-auto-profile: New file. contrib/: 2016-06-23 Andi Kleen <ak@linux.intel.com> * gen_autofdo_event.py: New file to regenerate gcc-auto-profile. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@237731 138bc75d-0d04-0410-961f-82ee72b054a4
