GCC 8 Release Series Changes, New Features, and Fixes This page is a "brief" summary of some of the huge number of improvements in GCC 8. You may also want to check out our Porting to GCC 8 page and the full GCC documentation. Caveats Support for the obsolete SDB/coff debug info format has been removed. The option -gcoff no longer does anything. The Cilk+ extensions to the C and C++ languages have

3.11 Options That Control Optimization ¶ These options control various sorts of optimizations. Without any optimization option, the compiler’s goal is to reduce the cost of compilation and to make debugging produce the expected results. Statements are independent: if you stop the program with a breakpoint between statements, you can then assign a new value to any variable or change the program cou

6.50.2 Extended Asm - Assembler Instructions with C Expression Operands ¶ With extended asm you can read and write C variables from assembler and perform jumps from assembler code to C labels. Extended asm syntax uses colons (‘:’) to delimit the operand parameters after the assembler template: asm asm-qualifiers ( AssemblerTemplate : OutputOperands [ : InputOperands [ : Clobbers ] ]) asm asm-quali

3.12 Program Instrumentation Options ¶ GCC supports a number of command-line options that control adding run-time instrumentation to the code it normally generates. For example, one purpose of instrumentation is collect profiling statistics for use in finding program hot spots, code coverage analysis, or profile-guided optimizations. Another class of program instrumentation is adding run-time chec

GCC supports different dialects of C++, corresponding to the multiple published ISO standards. Which standard it implements can be selected using the -std= command-line option.

The GOMP project consists of implementation of OpenMP and OpenACC to permit annotating the source code to permit running it concurrently with thread parallelization and on offloading devices (accelerators such as GPUs), including the associated run-time library and API routines. Both OpenMP and OpenACC are supported with GCC's C, C++ and Fortran compilers. Content Usage Documentation History and P

3.19.1 AArch64 Options ¶ These options are defined for AArch64 implementations: -mabi=name ¶ Generate code for the specified data model. Permissible values are ‘ilp32’ for SysV-like data model where int, long int and pointers are 32 bits, and ‘lp64’ for SysV-like data model where int is 32 bits, but long int and pointers are 64 bits. The default depends on the specific target configuration. Note t

GCC 5 Release Series Changes, New Features, and Fixes Caveats The default mode for C is now -std=gnu11 instead of -std=gnu89. The C++ runtime library (libstdc++) uses a new ABI by default (see below). The Graphite framework for loop optimizations no longer requires the CLooG library, only ISL version 0.14 (recommended) or 0.12.2. The installation manual contains more information about requirements

gfortran — the GNU Fortran compiler, part of GCC Gfortran is the name of the GNU Fortran project, developing a free Fortran 95/2003/2008/2018 compiler for GCC, the GNU Compiler Collection. The gfortran development effort uses an open development environment in order to attract a larger team of developers and to ensure that gfortran can work on multiple architectures and diverse environments.

Support for the standard ISO/IEC 9899:2011 (C11) in GCC (draft n1570, PDF) GCC 4.9 Changes: “ISO C11 support is now at a similar level of completeness to ISO C99 support: substantially complete modulo bugs, extended identifiers (supported except for corner cases when -fextended-identifiers is used), floating-point issues (mainly but not entirely relating to optional C99 features from Annexes F and

Prerequisites for GCC GCC requires that various tools and packages be available for use in the build procedure. Modifying GCC sources requires additional tools described below. Tools/packages necessary for building GCC ISO C++11 compiler Necessary to bootstrap GCC. GCC 4.8.3 or newer has sufficient support for used C++11 features. Versions of GCC prior to 11 also allow bootstrapping with an ISO C+

6 Extensions to the C Language Family ¶ GNU C provides several language features not found in ISO standard C. (The -pedantic option directs GCC to print a warning message if any of these features is used.) To test for the availability of these features in conditional compilation, check for a predefined macro __GNUC__, which is always defined under GCC. These extensions are available in C and Objec

3.8 Options to Request or Suppress Warnings ¶ Warnings are diagnostic messages that report constructions that are not inherently erroneous but that are risky or suggest there may have been an error. The following language-independent options do not enable specific warnings but control the kinds of diagnostics produced by GCC. -fsyntax-only ¶ Check the code for syntax errors, but don’t do anything

3.7.2 Common Predefined Macros ¶ The common predefined macros are GNU C extensions. They are available with the same meanings regardless of the machine or operating system on which you are using GNU C or GNU Fortran. Their names all start with double underscores. __COUNTER__ This macro expands to sequential integral values starting from 0. In conjunction with the ## operator, this provides a conve

GCC, the GNU Compiler Collection The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Ada, Go, D and Modula-2 as well as libraries for these languages (libstdc++,...). GCC was originally written as the compiler for the GNU operating system. The GNU system was developed to be 100% free software, free in the sense that it respects the user's freedom. We strive to provide
