2019-11-06introduce -fcallgraph-info optionEric Botcazou18-52/+449
This was first submitted many years ago https://gcc.gnu.org/ml/gcc-patches/2010-10/msg02468.html The command line option -fcallgraph-info is added and makes the compiler generate another output file (xxx.ci) for each compilation unit (or LTO partitoin), which is a valid VCG file (you can launch your favorite VCG viewer on it unmodified) and contains the "final" callgraph of the unit. "final" is a bit of a misnomer as this is actually the callgraph at RTL expansion time, but since most high-level optimizations are done at the Tree level and RTL doesn't usually fiddle with calls, it's final in almost all cases. Moreover, the nodes can be decorated with additional info: -fcallgraph-info=su adds stack usage info and -fcallgraph-info=da dynamic allocation info. for gcc/ChangeLog From Eric Botcazou <ebotcazou@adacore.com>, Alexandre Oliva <oliva@adacore.com> * common.opt (-fcallgraph-info[=]): New option. * doc/invoke.texi (Developer options): Document it. * opts.c (common_handle_option): Handle it. * builtins.c (expand_builtin_alloca): Record allocation if -fcallgraph-info=da. * calls.c (expand_call): If -fcallgraph-info, record the call.

2019-11-06Warn about inconsistent OpenACC nested reduction clausesFrederik Harwath12-4/+2290
OpenACC (cf. OpenACC 2.7, section 2.9.11. "reduction clause"; this was first clarified by OpenACC 2.6) requires that, if a variable is used in reduction clauses on two nested loops, then there must be reduction clauses for that variable on all loops that are nested in between the two loops and all these reduction clauses must use the same operator. This commit introduces a check for that property which reports warnings if it is violated. 2019-11-06 Gergö Barany <gergo@codesourcery.com> Frederik Harwath <frederik@codesourcery.com> Thomas Schwinge <thomas@codesourcery.com> gcc/ * omp-low.c (struct omp_context): New fields local_reduction_clauses, outer_reduction_clauses.

2019-11-05Implement C++20 operator<=>.Jason Merrill56-127/+2653
There are three major pieces to this support: scalar operator<=>, synthesis of comparison operators, and rewritten/reversed overload resolution (e.g. a < b becomes 0 > b <=> a). Unlike other defaulted functions, where we use synthesized_method_walk to semi-simulate what the definition of the function will be like, this patch determines the characteristics of a comparison operator by trying to define it. My handling of non-dependent rewritten operators in templates can still use some work: build_min_non_dep_op_overload can't understand the rewrites and crashes, so I'm avoiding it for now by clearing *overload. This means we'll do name lookup again at instantiation time, which can incorrectly mean a different result. I'll poke at this more in stage 3. I'm leaving out a fourth section ("strong structural equality") even though I've implemented it, because it seems likely to change radically tomorrow. Thanks to Tim van Deurzen and Jakub for implementing lexing of the <=> operator, and Jonathan for the initial <compare> header. gcc/cp/ * cp-tree.h (struct lang_decl_fn): Add maybe_deleted bitfield.

2019-11-05Fix conversions for built-in operator overloading candidates.Jason Merrill5-28/+41
While working on C++20 operator<=>, I noticed that build_new_op_1 was doing too much conversion when a built-in candidate was selected; the standard says it should only perform user-defined conversions, and then leave the normal operator semantics to handle any standard conversions. This is important for operator<=> because a comparison of two different unscoped enums is ill-formed; if we promote the enums to int here, cp_build_binary_op never gets to see the original operand types, so we can't give the error. I'm also disabling -Wmaybe-uninitialized for expmed.c to avoid the bootstrap failure from the last time I applied this patch. * call.c (build_new_op_1): Don't apply any standard conversions to the operands of a built-in operator. Don't suppress conversions in cp_build_unary_op. * typeck.c (cp_build_unary_op): Do integral promotions for enums. PR tree-optimization/91825 * expmed.c: Reduce -Wmaybe-uninitialized to warning.

2019-11-05Use vec instead of raw array for built-in candidates.Jason Merrill2-40/+33
My operator<=> patch wants to split up build_new_op_1, which makes using a tree array as well as the vec inconvenient. build_new_op_1 already has a vec, and build_conditional_expr_1 can release its vec right away, so this doesn't increase garbage at all. * call.c (build_builtin_candidate): Take args in a vec.

2019-11-05Allow libcalls for complex memcpy when optimizing for size.Jim Wilson4-2/+43
The RISC-V backend wants to use a libcall when optimizing for size if more than 6 instructions are needed. Emit_move_complex asks for no libcalls. This case requires 8 insns for rv64 and 16 insns for rv32, so we get fallback code that emits a loop. Commit_one_edge_insertion doesn't allow code inserted for a phi node on an edge to end with a branch, and so this triggers an assertion. This problem goes away if we allow libcalls when optimizing for size, which gives the code the RISC-V backend wants, and avoids triggering the assert. gcc/ PR middle-end/92263 * expr.c (emit_move_complex): Only use BLOCK_OP_NO_LIBCALL when optimize_insn_for_speed_p is true. gcc/testsuite/ PR middle-end/92263 * gcc.dg/pr92263.c: New.
