Comparing the fre dump file shows no obvious change of the segment fault function proves it to be a target issue. frame_pointer_needed is set to true in reload pass setup_can_eliminate, but regs_ever_live[31] is false, pro_and_epilogue uses it without live check causing CPU2006 465.tonto segment fault of loading from invalid addresses due to r31 not saved/restored.

2020-04-26c++: Explicit constructor called in copy-initialization [PR90320]Marek Polacek5-5/+66
This test is rejected with a bogus "use of deleted function" error starting with r225705 whereby convert_like_real/ck_base no longer sets LOOKUP_ONLYCONVERTING for user_conv_p conversions. This does not seem to be always correct. To recap, when we have something like T t = x where T is a class type and the type of x is not T or derived from T, we perform copy-initialization, something like: 1. choose a user-defined conversion to convert x to T, the result is a prvalue, 2. use this prvalue to direct-initialize t. In the second step, explicit constructors should be considered, since we're direct-initializing. This is what r225705 fixed. In this PR we are dealing with the first step, I think, where explicit constructors should be skipped. [over.match.copy] says "The converting constructors of T are candidate functions" which clearly eliminates explicit constructors. But we also have to copy-initialize the argument we are passing to such a converting constructor, and here we should disregard explicit constructors too. In this testcase we have V v = m; and we choose V::V(M) to convert m to V. But we wrongly choose the explicit M::M<M&>(M&) to copy-initialize the argument; it's a better match for a non-const lvalue than the implicit M::M(const M&) but because it's explicit, we shouldn't use it. When convert_like is processing the ck_user conversion -- the convfn is V::V(M) -- it can see that cand->flags contains LOOKUP_ONLYCONVERTING, but then when we're in build_over_call for this convfn, we have no way to pass the flag to convert_like for the argument 'm', because convert_like doesn't take flags. Fixed by creating a new conversion flag, copy_init_p, set in ck_base/ck_rvalue to signal that explicit constructors should be skipped. LOOKUP_COPY_PARM looks relevant, but again, it's a LOOKUP_* flag, so can't pass it to convert_like. DR 899 also seemed related, but that deals with direct-init contexts only.

Fix a problem with the libffi testsuite using a method to determine the compiler to use resulting in the tool being different from one the library has been built with, and causing a catastrophic failure from the inability to actually choose any compiler at all in a cross-compilation configuration.

2020-04-25cselim: Don't assume it is safe to cstore replace a store to a local ↵Jakub Jelinek8-6/+89
variable with unknown offset [PR94734] As the new testcase shows, it is not safe to assume we can optimize a conditional store into an automatic non-addressable var, we can do it only if we can prove that the unconditional load or store actually will not be outside of the boundaries of the variable. If the offset and size are constant, we can, but this is already all checked in !tree_could_trap_p, otherwise we really need to check for a dominating unconditional store, or for the specific case of automatic non-addressable variables, it is enough if there is a dominating load (that is what those 4 testcases have). tree-ssa-phiopt.c has some infrastructure for this already, see the add_or_mark_expr method etc., but right now it handles only MEM_REFs with SSA_NAME first operand and some integral offset. So, I think it can be for GCC11 extended to handle other memory references, possibly up to just doing get_inner_reference and hasing based on the base, offset expressions and bit_offset and bit_size, and have also a special case that for !TREE_ADDRESSABLE automatic variables it could ignore whether something is a load or store because the local stack should be always writable. But it feels way too dangerous to do this this late for GCC10, so this patch just restricts the optimization to the safe case (where lhs doesn't trap), and on Richi's request also ignores TREE_ADDRESSABLE bit if flag_store_data_races, because my understanding the reason for TREE_ADDRESSABLE check is that we want to avoid introducing store data races (if address of an automatic var escapes, some other thread could be accessing it concurrently). 2020-04-25 Jakub Jelinek <jakub@redhat.com> Richard Biener <rguenther@suse.de> PR tree-optimization/94734 PR tree-optimization/89430 * tree-ssa-phiopt.c: Include tree-eh.h.

2020-04-24aarch64: Add an extra comment to arm_sve.hRichard Sandiford2-0/+9
I've had a couple of conversations now in which the shortness of arm_sve.h was causing confusion, with people thinking that the types and intrinsics were missing. It seems worth adding a comment to explain what's going on. 2020-04-24 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/arm_sve.h: Add a comment.
2020-04-24rtl combine should consider NaNs when generate fp min/max [PR94708]Haijian Zhang4-1/+28
As discussed on PR94708, it's unsafe for rtl combine to generate fp min/max under -funsafe-math-optimizations, considering NaNs. In addition to flag_unsafe_math_optimizations check, we also need to do extra mode feature testing here: && !HONOR_NANS (mode) && !HONOR_SIGNED_ZEROS (mode) 2020-04-24 Haijian Zhang <z.zhanghaijian@huawei.com> gcc/ PR rtl-optimization/94708 * combine.c (simplify_if_then_else): Add check for !HONOR_NANS (mode) && !HONOR_SIGNED_ZEROS (mode). gcc/testsuite/ PR fortran/94708 * gfortran.dg/pr94708.f90: New test.

2020-04-23gotest: increase the test timeouteric fang2-2/+2
The default test timeout duration of the gc compiler is 10 minutes, and the current default timeout duration of gofrontend is 240 seconds, which is not long enough for some big tests. This CL changes it to 600s, so that all tests have enough time to complete. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/229657

2020-04-24libstdc++: Fix constructor constraints for std::any (PR 90415)Jonathan Wakely6-71/+255
This removes a non-standard extension to std::any which causes errors for valid code, due to recursive instantiation of a trait that isn't supposed to be in the constraints. It also removes some incorrect constraints on the in_place_type<T> constructors and emplace members, which were preventing creating a std::any object with another std::any as the contained value. 2020-04-24 Kamlesh Kumar <kamleshbhalui@gmail.com> Jonathan Wakely <jwakely@redhat.com> PR libstdc++/90415 PR libstdc++/92156 * include/std/any (any): Rename template parameters for consistency with the standard.
