2019-10-28[C++ PATCH] simplify deferred parsing lexerNathan Sidwell3-56/+63
https://gcc.gnu.org/ml/gcc-patches/2019-10/msg01962.html We use an eof_token global variable as a sentinel on a deferred parse (such as in-class function definitions, or default args). This complicates retrieving the next token in certain places. As such deferred parses always nest properly and completely before resuming the outer lexer, we can simply morph the token after the deferred buffer into a CPP_EOF token and restore it afterwards. I finally got around to implementing it with this patch. One complication is that we have to change the discriminator for when the token's value is a tree. We can't look at the token's type because it might have been overwritten. I add a bool flag to the token (there's several spare bits), and use that. This does simplify the discriminator because we just check a single bit, rather than a set of token types. * parser.h (struct cp_token): Drop {ENUM,BOOL}_BITFIELD C-ism. Add tree_check_p flag, use as nested union discriminator. (struct cp_lexer): Add saved_type & saved_keyword fields. * parser.c (eof_token): Delete.

2019-10-28Move jump threading before reloadIlya Leoshkevich6-11/+66
r266734 has introduced a new instance of jump threading pass in order to take advantage of opportunities that combine opens up. It was perceived back then that it was beneficial to delay it after reload, since that might produce even more such opportunities. Unfortunately jump threading interferes with hot/cold partitioning. In the code from PR92007, it converts the following +-------------------------- 2/HOT ------------------------+ | | v v 3/HOT --> 5/HOT --> 8/HOT --> 11/COLD --> 6/HOT --EH--> 16/HOT | ^ | | +-------------------------------+ into the following: +---------------------- 2/HOT ------------------+ | | v v 3/HOT --> 8/HOT --> 11/COLD --> 6/COLD --EH--> 16/HOT This makes hot bb 6 dominated by cold bb 11, and because of this fixup_partitions makes bb 6 cold as well, which in turn makes EH edge 6->16 a crossing one. Not only can't we have crossing EH edges, we are also not allowed to introduce new crossing edges after reload in general, since it might require extra registers on some targets. Therefore, move the jump threading pass between combine and hot/cold partitioning. Building SPEC 2006 and SPEC 2017 with the old and the new code indicates that: * When doing jump threading right after reload, 3889 edges are threaded. * When doing jump threading right after combine, 3918 edges are threaded. This means this change will not introduce performance regressions. gcc/ChangeLog: 2019-10-28 Ilya Leoshkevich <iii@linux.ibm.com> PR rtl-optimization/92007 * cfgcleanup.c (thread_jump): Add an assertion that we don't call it after reload if hot/cold partitioning has been done.

2019-10-28rs6000: Enable limited unrolling at -O2Jiufu Guo13-6/+70
In PR88760, there are a few disscussion about improve or tune unroller for targets. And we would agree to enable unroller for small loops at O2 first. And we could see performance improvement(~10%) for below code: ``` subroutine foo (i, i1, block) integer :: i, i1 integer :: block(9, 9, 9) block(i:9,1,i1) = block(i:9,1,i1) - 10 end subroutine foo ``` This kind of code occurs a few times in exchange2 benchmark. Similar C code: ``` for (i = 0; i < n; i++) arr[i] = arr[i] - 10; ``` On powerpcle, for O2 , enable -funroll-loops and limit PARAM_MAX_UNROLL_TIMES=2 and PARAM_MAX_UNROLLED_INSNS=20, we can see >2% overall improvement for SPEC2017.

2019-10-25Use implicitly-defined copy operations for test iteratorsJonathan Wakely2-50/+47
All of these special member functions do exactly what the compiler would do anyway. By defining them as defaulted for C++11 and later we prevent move constructors and move assignment operators being defined (which is consistent with the previous semantics). Also move default init of the input_iterator_wrapper members from the derived constructor to the protected base constructor. * testsuite/util/testsuite_iterators.h (output_iterator_wrapper) (input_iterator_wrapper, forward_iterator_wrapper) bidirectional_iterator_wrapper, random_access_iterator_wrapper): Remove user-provided copy constructors and copy assignment operators so they are defined implicitly. (input_iterator_wrapper): Initialize members in default constructor. (forward_iterator_wrapper): Remove assignments to members of base. From-SVN: r277459
2019-10-25Fix compilation with ClangJonathan Wakely3-1/+36

2019-10-25Fix reductions for fully-masked loopsRichard Sandiford19-60/+144
Now that vectorizable_operation vectorises most loop stmts involved in a reduction, it needs to be aware of reductions in fully-masked loops. The LOOP_VINFO_CAN_FULLY_MASK_P parts of vectorizable_reduction now only apply to cases that use vect_transform_reduction. This new way of doing things is definitely an improvement for SVE though, since it means we can lift the old restriction of not using fully-masked loops for reduction chains. 2019-10-25 Richard Sandiford <richard.sandiford@arm.com> gcc/ * tree-vect-loop.c (vectorizable_reduction): Restrict the LOOP_VINFO_CAN_FULLY_MASK_P handling to cases that will be handled by vect_transform_reduction.
