2019-10-29Add a simulate_builin_function_decl langhookRichard Sandiford12-18/+118
Although it's possible to define the SVE intrinsics in a normal header file, it's much more convenient to define them directly in the compiler. This also speeds up compilation and gives better error messages. The idea is therefore for arm_sve.h (the main intrinsics header file) to have the pragma: #pragma GCC aarch64 "arm_sve.h" telling GCC to define (almost) everything arm_sve.h needs to define. The target then needs a way of injecting new built-in function declarations during compilation. The main hook for defining built-in functions is add_builtin_function. This is designed for use at start-up, and so has various features that are correct in that context but not for the pragma above: (1) the location is always BUILTINS_LOCATION, whereas for arm_sve.h it ought to be the location of the pragma. (2) the function is only immediately visible if it's in the implementation namespace, whereas the pragma is deliberately injecting functions into the general namespace. (3) there's no attempt to emulate a normal function declaration in C or C++, whereas functions declared by the pragma should be checked in the same way as an open-coded declaration would be. E.g. we should get an error if there was a previous incompatible declaration. (4) in C++, the function is treated as extern "C" and so can't be overloaded, whereas SVE intrinsics do use function overloading. This patch therefore adds a hook that targets can use to inject the equivalent of a source-level function declaration, but bound to a BUILT_IN_MD function. The main SVE intrinsic patch has tests to make sure that we report an error for conflicting definitions that appear either before or after including arm_sve.h. 2019-10-29 Richard Sandiford <richard.sandiford@arm.com> gcc/ * langhooks.h (lang_hooks::simulate_builtin_function_decl): New hook.

2019-10-28gcc/riscv: Add a mechanism to remove some calls to _riscv_save_0Andrew Burgess14-1/+636
When using the -msave-restore flag we end up with calls to _riscv_save_0 and _riscv_restore_0. These functions adjust the stack and save or restore the return address. Due to grouping multiple save/restore stub functions together the save/restore 0 calls actually save s0, s1, s2, and the return address, but only the return address actually matters. Leaf functions don't call the save/restore stubs, so whenever we do see a call to the save/restore stubs, the store of the return address is required. If we look in gcc/config/riscv/riscv.c at the function riscv_expand_prologue and riscv_expand_epilogue we can see that it would be reasonably easy to adjust these functions to avoid the calls to the save/restore stubs for those cases where we are about to call _riscv_save_0 and _riscv_restore_0, however, the actual code size saving this would give is debatable, with linker relaxation, the calls to save/restore are often just 4-bytes, and can sometimes even be 2-bytes, while leaving the stack adjust and return address save inline is always going to be 4-bytes. The interesting case is when we call _riscv_save_0 and _riscv_restore_0, and also have a frame that would (without save/restore) have resulted in a tail call. In this case if we could remove the save/restore calls, and restore the tail call then we would get a real size saving. The problem is that the choice of generating a tail call or not is done during the gimple expand pass, at which point we don't know how many registers we need to save (or restore). The solution presented in this patch offers a partial solution to this problem. By using the TARGET_MACHINE_DEPENDENT_REORG pass to implement a very limited pattern matching we identify functions that call _riscv_save_0 and _riscv_restore_0, and which could be converted to make use of a tail call. These functions are then converted to the non save/restore tail call form. This should result in a code size reduction when compiling with -Os and with the -msave-restore flag. gcc/ChangeLog: * config.gcc: Add riscv-sr.o to extra_objs for riscv. * config/riscv/riscv-sr.c: New file. * config/riscv/riscv.c (riscv_reorg): New function.

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.

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.

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.

2019-10-26rs6000: Fix allocate_stack in a corner case (PR91289)Segher Boessenkool2-4/+15
When we have -fstack-limit-symbol with sysv we can end up with a non- existing instruction (you cannot add an immediate to register 0). Fix this by using register 11 instead. It might be used for something else already though, so save and restore its value around this. In optimizing compiles these extra moves are usually removed again: the restore by cprop_hardreg, and then the save by rtl_dce. PR target/91289 * config/rs6000/rs6000-logue.c (rs6000_emit_allocate_stack): Don't add an immediate to r0; use r11 instead. Save and restore r11 to r0 around this. From-SVN: r277472
