From c3a2ba10b272fd9581560604284da2a6283bcde0 Mon Sep 17 00:00:00 2001 From: Iain Buclaw Date: Sun, 7 Jun 2020 16:50:46 +0200 Subject: [PATCH] d: Merge upstream dmd b0df0e982 Adds a struct ParameterList to encapulate parameter and vararg information in the front-end. Reviewed-on: https://github.com/dlang/dmd/pull/11226 gcc/d/ChangeLog: * dmd/MERGE: Merge upstream dmd b0df0e982. * d-builtins.cc (build_frontend_type): Use VarArg for varargs_p. * d-codegen.cc (declaration_type): Call TypeFunction::create with argument VARARGnone. (parameter_type): Likewise. (d_build_call): Use new field names and member functions. * d-target.cc (Target::cppParameterType): Call TypeFunction::create with argument VARARGnone. * types.cc (TypeVisitor::visit (TypeFunction *): Use new field names and member functions. --- gcc/d/d-builtins.cc | 6 +- gcc/d/d-codegen.cc | 12 ++-- gcc/d/d-target.cc | 2 +- gcc/d/dmd/MERGE | 2 +- gcc/d/dmd/arrayop.c | 2 +- gcc/d/dmd/clone.c | 22 +++---- gcc/d/dmd/cond.c | 2 +- gcc/d/dmd/cppmangle.c | 6 +- gcc/d/dmd/dcast.c | 12 ++-- gcc/d/dmd/dclass.c | 2 +- gcc/d/dmd/declaration.h | 6 +- gcc/d/dmd/delegatize.c | 2 +- gcc/d/dmd/dinterpret.c | 8 +-- gcc/d/dmd/dmangle.c | 4 +- gcc/d/dmd/doc.c | 11 ++-- gcc/d/dmd/dstruct.c | 2 +- gcc/d/dmd/dtemplate.c | 84 ++++++++++++------------ gcc/d/dmd/escape.c | 18 +++--- gcc/d/dmd/expression.c | 32 +++++----- gcc/d/dmd/expressionsem.c | 22 +++---- gcc/d/dmd/func.c | 99 ++++++++++++++-------------- gcc/d/dmd/hdrgen.c | 10 +-- gcc/d/dmd/hdrgen.h | 2 +- gcc/d/dmd/initsem.c | 3 +- gcc/d/dmd/json.c | 2 +- gcc/d/dmd/mtype.c | 131 +++++++++++++++++++++++--------------- gcc/d/dmd/mtype.h | 80 +++++++++++++---------- gcc/d/dmd/opover.c | 10 +-- gcc/d/dmd/optimize.c | 2 +- gcc/d/dmd/parse.c | 36 ++++++----- gcc/d/dmd/parse.h | 2 +- gcc/d/dmd/statementsem.c | 23 +++---- gcc/d/dmd/traits.c | 18 +++--- gcc/d/types.cc | 17 ++--- 34 files changed, 369 insertions(+), 323 deletions(-) diff --git a/gcc/d/d-builtins.cc b/gcc/d/d-builtins.cc index bd7e3eb15d7..33221ea3229 100644 --- a/gcc/d/d-builtins.cc +++ b/gcc/d/d-builtins.cc @@ -282,7 +282,7 @@ build_frontend_type (tree type) if (dtype) { tree parms = TYPE_ARG_TYPES (type);
