gdc - A GCC-based compiler for the D language
gdc [-c] [-g] [-pg] [-Olevel] [-Idir...] [-Ldir...] [-o outfile] infile... For any given input file, the file name suffix determines what kind of compilation is done: file.d D source files. file.di D interface files. file.o Object files to link in. file.a Library files to link in
The gdc command is a frontend to gcc and supports many of the same options. This manual only documents the options specific to gdc. Most of these have both positive and negative forms; the negative form of -ffoo would be -fno-foo. This manual documents only one of these two forms, whichever one is not the default. The gdc command may be used to compile D source code into an object file, link a collection of object files together, or do both in sequence. Only the most useful options are listed here; see below for the remainder.
-frelease Compile release version. -funittest Compile in unittest code. -fno-assert Turn off code generation for runtime assert()'s. -fno-invariants Turn off code generation for runtime invariant()'s. -fno-in Turn off code generation for runtime in() contracts. -fno-out Turn off code generation for runtime out() contracts. -fno-bounds-check Turns off array bounds checking for all functions. -fno-builtin Don't recognize built-in functions that do not begin with __builtin_ as prefix. -fno-emit-moduleinfo Turns off generation of module information and related functions. -fd-verbose Print information about D language processing to stdout. -fproperty For D2, enforce @property syntax. -fd-vtls List all variables going into thread local storage. -fignore-unknown-pragmas Ignore unsupported pragmas. -fsplit-dynamic-arrays Split dynamic arrays into length and pointer when passing to functions. -femit-templates Control template emission behaviour. Turning on this option will emit all templates, but make them private to the translation unit. The executable will have multiple copies of code and data. Turning off this option will tell the compiler to not emit templates at all. The default behaviour is to emit templates, but only if the compiler determines that it needs to. -fdebug=opt Compile in debug code into the program. These are supported options: level Compile in debug code <= level. ident Compile in debug code identified by ident. -fdeps=filename Write module dependencies to filename. -fmake-deps=filename Write makefile dependency output to the given file. -fmake-mdeps=filename Like -fmake-deps=filename but ignore system header files. -fonly=filename Process all modules specified on the command line, but only generate code for the module specified by the argument. -fversion=opt Compile in version code into the program. These are the supported options: level Compile in version code >= level. ident Compile in debug code identified by ident. -fintfc Generate D interface files. -fintfc-dir=directory Write D interface files to directory. -fintfc-file=filename Write D interface file to filename. -fdoc Generate documentation. -fdoc-dir=directory Write documentation file in directory. -fdoc-file=filename Write documentation file to filename. -fdoc-inc=filename Include a Ddoc macro file. -fXf=filename Write JSON file to filename. -fdump-source Dump decoded UTF-8 text from source. -Wcast-result Warn about casts that will produce a null or nil result. -Werror Make all warnings into errors. -Wno-deprecated Do not warn about usage of deprecated features. -Wunknown-pragmas Warn when a pragma is encountered that is not understood by GDC.
