2020-06-03c++: constrained nested partial specialization [PR92103]Patrick Palka2-9/+32
When determining the most specialized partial specialization of a primary template that is nested inside a class template, we first tsubst the outer template arguments into the TEMPLATE_DECL of each partial specialization, and then check for satisfaction of each of the new TEMPLATE_DECL's constraints. But tsubst_template_decl does not currently guarantee that constraints from the original DECL_TEMPLATE_RESULT get reattached to the new DECL_TEMPLATE_RESULT. In the testcase below, this leads to the constraints_satisfied_p check in most_specialized_partial_spec to trivially return true for each of the partial specializations. I'm not sure if such a guarantee would be desirable, but in this case we can just check constraints_satisfied_p on the original TEMPLATE_DECL instead of on the tsubsted TEMPLATE_DECL here, which is what this patch does (alongside some reorganizing). gcc/cp/ChangeLog: PR c++/92103 * pt.c (most_specialized_partial_spec): Reorganize the loop over DECL_TEMPLATE_SPECIALIZATIONS. Check constraints_satisfied_p on the original template declaration, not on the tsubsted one. gcc/testsuite/ChangeLog: PR c++/92103 * g++.dg/cpp2a/concepts-partial-spec7.C: New test.
2020-06-03Optimize ODR enum streamingJan Hubicka13-89/+379
it turns out that half of the global decl stream of cc1 LTO build consits TREE_LISTS, identifiers and integer cosntats representing TYPE_VALUES of enums. Those are streamed only to produce ODR warning and used otherwise, so this patch moves the info to a separate section that is represented and streamed more effectively. This also adds place for more info that may be used for ODR diagnostics (i.e. at the moment we do not warn when the declarations differs i.e. by the associated member functions and their types) and the type inheritance graph rather then poluting the global stream. I was bit unsure what enums we want to store into the section. All parsed enums is probably too expensive, only those enums streamed to represent IL is bit hard to get, so I went for those seen by free lang data. As a plus we now get bit more precise warning because also the location of mismatched enum CONST_DECL is streamed. It changes: [WPA] read 4608466 unshared trees [WPA] read 2942094 mergeable SCCs of average size 1.365328 [WPA] 8625389 tree bodies read in total [WPA] tree SCC table: size 524287, 247652 elements, collision ratio: 0.383702 [WPA] tree SCC max chain length 2 (size 1) [WPA] Compared 2694442 SCCs, 228 collisions (0.000085) [WPA] Merged 2694419 SCCs [WPA] Merged 3731982 tree bodies [WPA] Merged 633335 types [WPA] 122077 types prevailed (155548 associated trees) ...

[WPA] Size of mmap'd section odr_types: 29054816 bytes So number of SCCs streamed drops to 38% and the number of unshared trees (that are bit misnamed since it is mostly integer_cst) to 37%. Things speeds up correspondingly, but I did not save time report from previous build. The enum values are still quite surprisingly large. I may take a look into ways getting it smaller incrementally, but it streams reasonably fast: Time variable usr sys wall GGC phase opt and generate : 25.20 ( 68%) 10.88 ( 72%) 36.13 ( 69%) 868060 kB ( 52%) phase stream in : 4.46 ( 12%) 0.90 ( 6%) 5.38 ( 10%) 790724 kB ( 48%) phase stream out : 6.69 ( 18%) 3.32 ( 22%) 10.03 ( 19%) 8 kB ( 0%) ipa lto gimple in : 0.79 ( 2%) 1.86 ( 12%) 2.39 ( 5%) 252612 kB ( 15%) ipa lto gimple out : 2.48 ( 7%) 0.78 ( 5%) 3.26 ( 6%) 0 kB ( 0%) ipa lto decl in : 1.71 ( 5%) 0.46 ( 3%) 2.34 ( 4%) 417883 kB ( 25%) ipa lto decl out : 3.28 ( 9%) 0.07 ( 0%) 3.27 ( 6%) 0 kB ( 0%) whopr wpa I/O : 0.40 ( 1%) 2.24 ( 15%) 2.77 ( 5%) 8 kB ( 0%) lto stream decompression : 1.38 ( 4%) 0.31 ( 2%) 1.36 ( 3%) 0 kB ( 0%) ipa ODR types : 0.18 ( 0%) 0.02 ( 0%) 0.25 ( 0%) 0 kB ( 0%) ipa inlining heuristics : 11.64 ( 31%) 1.45 ( 10%) 13.12 ( 25%) 453160 kB ( 27%) ipa pure const : 1.74 ( 5%) 0.00 ( 0%) 1.76 ( 3%) 0 kB ( 0%) ipa icf : 1.72 ( 5%) 5.33 ( 35%) 7.06 ( 13%) 16593 kB ( 1%) whopr partitioning : 2.22 ( 6%) 0.01 ( 0%) 2.23 ( 4%) 5689 kB ( 0%) TOTAL : 37.17 15.20 52.46 1660886 kB LTO-bootstrapped/regtested x86_64-linux, will comit it shortly. gcc/ChangeLog: 2020-06-03 Jan Hubicka <hubicka@ucw.cz> * ipa-devirt.c: Include data-streamer.h, lto-streamer.h and streamer-hooks.h.

2020-06-02jit: fix __builtin_unreachable [PR 95426]David Malcolm3-1/+511
PR jit/95426 reports a crash deep inside "expand" when using __builtin_unreachable via gcc_jit_context_get_builtin_function, due to BLOCK_FOR_INSN being erroneously used on a barrier within rtl_verify_bb_pointers. The root cause turns out to be that I didn't implement LANG_HOOKS_COMMON_ATTRIBUTE_TABLE and LANG_HOOKS_FORMAT_ATTRIBUTE_TABLE for the jit "frontend". When building a decl for the builtin, the libgccjit frontend generates a chain of attributes names, but when this is passed to decl_attributes and the attributes are looked up by namespace and name within lookup_scoped_attribute_spec, attributes_table is empty. Hence no attributes were being associated with the fndecl, and so ECF_NORETURN was not set on the gimple_call (along with various other flags missing on the decl, etc), and so the call is treated as not terminating its BB, and so the CFG rapidly diverges from the equivalent created by the C frontend. This patch fixes things by implementing these langhooks, copying the minimal attribute-handling code from LTO. I stepped through the creation of the fndecl and verified that with this fix it has the same attributes as the equivalent created by the C frontend. gcc/jit/ChangeLog: PR jit/95426 * dummy-frontend.c: Include "options.h", "stringpool.h", and "attribs.h".

2020-06-02coroutines: Wrap co_await in a target expr where needed [PR95050]Iain Sandoe2-2/+76
Since the co_await expression is mostly opaque to the existing machinery, we were hiding the details of the await_resume return value. If that needs to be wrapped in a target expression, then emulate this with the whole co_await. Similarly, if the await expression we build in response to co_await p.yield_value (e) is wrapped in a target expression, then we need to transfer that wrapper to the resultant CO_YIELD_EXPR (which is, itself, just a proxy for the underlying co_await). gcc/cp/ChangeLog: PR c++/95050 * coroutines.cc (build_co_await): Wrap the co_await expression in a TARGET_EXPR, where needed. (finish_co_yield_expr): Likewise. gcc/testsuite/ChangeLog: PR c++/95050 * g++.dg/coroutines/pr95050.C: New test.
