From 0fb57034770aa20adced4d176f34ca611c2945bf Mon Sep 17 00:00:00 2001 From: Iain Buclaw Date: Sun, 5 Dec 2021 17:11:12 +0100 Subject: d: Merge upstream dmd 568496d5b, druntime 178c44ff, phobos 574bf883b. D front-end changes: - Import dmd v2.098.0 - New ImportC module for compiling preprocessed C11 code into D. - New -ftransition=in switch. - Improved handling of new 'noreturn' type. Druntime changes: - Import druntime v2.098.0 - Fix broken import in core.sys.linux.perf_event module (PR103558). Phobos changes: - Import phobos v2.098.0 - All sources are now compiled with -fpreview=fieldwise. gcc/d/ChangeLog: * dmd/MERGE: Merge upstream dmd 568496d5b. * Make-lang.in (D_FRONTEND_OBJS): Add d/common-file.o, d/common-outbuffer.o, d/common-string.o, d/file_manager.o, d/importc.o. Remove d/root-outbuffer.o. (d/common-%.o): New recipe. * d-builtins.cc (build_frontend_type): Update for new front-end interface. (d_build_d_type_nodes): Set noreturn_type_node. * d-codegen.cc (d_build_call): Don't call function if one of the arguments is type 'noreturn'. (build_vthis_function): Propagate TYPE_QUAL_VOLATILE from original function type. * d-frontend.cc (eval_builtin): Update signature. (getTypeInfoType): Likewise. (toObjFile): New function. * d-gimplify.cc (d_gimplify_call_expr): Always evaluate arguments from left to right. * d-lang.cc (d_handle_option): Handle OPT_ftransition_in. (d_parse_file): Don't generate D main if it is declared in user code. * d-tree.h (CALL_EXPR_ARGS_ORDERED): Remove. (enum d_tree_index): Add DTI_BOTTOM_TYPE. (noreturn_type_node): New. * decl.cc (apply_pragma_crt): Remove. (DeclVisitor::visit): Update for new front-end interface. (DeclVisitor::visit (PragmaDeclaration *)): Don't handle crt_constructor and crt_destructor pragmas. (DeclVisitor::visit (VarDeclaration *)): Don't generate declarations of type 'noreturn'. (DeclVisitor::visit (FuncDeclaration *)): Stop adding parameters when 'noreturn' type has been encountered. (get_symbol_decl): Set DECL_STATIC_CONSTRUCTOR and DECL_STATIC_DESTRUCTOR on decl node if requested. (aggregate_initializer_decl): Update for new front-end interface. * expr.cc (ExprVisitor::visit (CallExp *)): Always use the 'this' object as the result of calling any constructor function. (ExprVisitor::visit): Update for new front-end interface. * gdc.texi (Runtime Options): Document -fmain and -ftransition=in. * lang.opt (ftransition=in): New option. * modules.cc (get_internal_fn): Update for new front-end interface. * types.cc (TypeVisitor::visit): Likewise. (TypeVisitor::visit (TypeNoreturn *)): Return noreturn_type_node. (TypeVisitor::visit (TypeFunction *)): Stop adding parameters when 'notreturn' type has been encountered. Qualify function types that return 'noreturn' as TYPE_QUAL_VOLATILE. libphobos/ChangeLog: PR d/103558 * libdruntime/MERGE: Merge upstream druntime 178c44ff. * libdruntime/Makefile.am (DRUNTIME_DSOURCES_LINUX): Add core/sys/linux/syscalls.d. (DRUNTIME_DSOURCES_OPENBSD): Add core/sys/openbsd/pthread_np.d. * libdruntime/Makefile.in: Regenerate. * src/MERGE: Merge upstream phobos 574bf883b. * src/Makefile.am (D_EXTRA_DFLAGS): Add -fpreview=fieldwise. * src/Makefile.in: Regenerate. * testsuite/libphobos.exceptions/assert_fail.d: Update test. * testsuite/libphobos.betterc/test22336.d: New test. --- gcc/d/dmd/common/outbuffer.h | 77 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 gcc/d/dmd/common/outbuffer.h (limited to 'gcc/d/dmd/common/outbuffer.h') diff --git a/gcc/d/dmd/common/outbuffer.h b/gcc/d/dmd/common/outbuffer.h new file mode 100644 index 0000000..a5e3f9c --- /dev/null +++ b/gcc/d/dmd/common/outbuffer.h @@ -0,0 +1,77 @@ + +/* Copyright (C) 1999-2021 by The D Language Foundation, All Rights Reserved + * written by Walter Bright + * http://www.digitalmars.com + * Distributed under the Boost Software License, Version 1.0. + * http://www.boost.org/LICENSE_1_0.txt + * https://github.com/dlang/dmd/blob/master/src/dmd/common/outbuffer.h + */ + +#pragma once + +#include "../root/dsystem.h" +#include "../root/dcompat.h" +#include "../root/rmem.h" + +class RootObject; + +struct OutBuffer +{ + // IMPORTANT: PLEASE KEEP STATE AND DESTRUCTOR IN SYNC WITH DEFINITION IN ./outbuffer.d. +private: + DArray data; + d_size_t offset; + bool notlinehead; + void *fileMapping; // pointer to a file mapping object not used on the C++ side +public: + bool doindent; + bool spaces; + int level; + + OutBuffer() + { + data = DArray(); + offset = 0; + + doindent = 0; + level = 0; + notlinehead = 0; + fileMapping = 0; + } + ~OutBuffer() + { + mem.xfree(data.ptr); + } + d_size_t length() const { return offset; } + char *extractData(); + void destroy(); + + void reserve(d_size_t nbytes); + void setsize(d_size_t size); + void reset(); + void write(const void *data, size_t nbytes); + void writestring(const char *string); + void prependstring(const char *string); + void writenl(); // write newline + void writeByte(unsigned b); + void writeUTF8(unsigned b); + void prependbyte(unsigned b); + void writewchar(unsigned w); + void writeword(unsigned w); + void writeUTF16(unsigned w); + void write4(unsigned w); + void write(const OutBuffer *buf); + void write(RootObject *obj); + void fill0(d_size_t nbytes); + void vprintf(const char *format, va_list args); + void printf(const char *format, ...); + void bracket(char left, char right); + d_size_t bracket(d_size_t i, const char *left, d_size_t j, const char *right); + void spread(d_size_t offset, d_size_t nbytes); + d_size_t insert(d_size_t offset, const void *data, d_size_t nbytes); + void remove(d_size_t offset, d_size_t nbytes); + // Append terminating null if necessary and get view of internal buffer + char *peekChars(); + // Append terminating null if necessary and take ownership of data + char *extractChars(); +}; -- cgit v1.1
