The Clang driver and language features are intentionally designed to be as compatible with the GNU GCC compiler as reasonably possible, easing migration from GCC to Clang. In most cases, code “just works”. Clang also provides an alternative driver, clang-cl, that is designed to be compatible with the Visual C++ compiler, cl.exe.
Additionally, Clang is designed to be highly compatible with GCC. Clang's command-line interface is similar to and shares many flags and options with GCC. Clang implements many GNU language extensions and enables them by default. Clang implements many GCC compiler intrinsics purely for compatibility. In fact, The first version of clang was Clang 1.0 and it was released with LLVM 2.6. The next version was Clang C++ which was able to parse GCC 4.2 libstdc, compile itself and function as a working code generator for non-trivial operations. And, Clang implements many GNU language extensions and enables them by default. Clang implements many GCC compiler intrinsics purely for compatibility. For example, even though Clang implements atomic intrinsics which correspond exactly with C11 atomics, it also implements GCC's __sync_* intrinsics for compatibility... In this manner, Some GCC compilation options cause the compiler to generate code that does not conform to the platform’s default ABI. Other options cause different program behavior for implementation-defined features that are not covered by an ABI.

What's the difference between gcc ggdb and gcc-gcc?
It is possible that there is no difference - depends on the OS native format and how portable you want the debugging info to be. See GCC manual Debugging Options. -g produces debugging information in the OS¹s native format (stabs, COFF, XCOFF, or DWARF 2). -ggdb produces debugging information specifically intended for gdb.
Which is the correct compiler gcc or gcc-conda?
Instead of gcc, the executable name of the compiler you use will be something like x86_64-conda_cos6-linux-gnu-gcc 2) Many build tools such as make and CMake search by default for a compiler named simply gcc, so we set environment variables to point these tools to the correct compiler.
What kind of compiler is the gcc compiler?
The GNU Compiler Collection includes front ends for C, C , Objective-C, Fortran, Java, Ada, and Go, as well as libraries for these languages (libstdc , libgcj,. MinGW, a contraction of "Minimalist GNU for Windows", is a port of the GNU Compiler Collection (GCC) ...
Is the gcc compiler the same as the g + + compiler?
In Apple’s version of GCC, both cc and gcc are actually symbolic links to the llvm-gcc compiler. Similarly, c++ and g++ are links to llvm-g++. For more information and examples see the following man pages: $ man gcc $ man make
Is the gcc compiler compatible with iso c90?
This turns off certain features of GCC that are incompatible with ISO C90 (when compiling C code), or of standard C++ (when compiling C++ code), such as the asmand typeofkeywords, and predefined macros such as unixand vaxthat identify the type of system you are using. It also enables the undesirable and rarely used ISO trigraph feature.
Is the arm compiler compatible with gcc source code?
The Arm Compiler includes many powerful space-saving and performance-enhancing optimization techniques, including low-level microarchitecture-specific instruction scheduling, unused section elimination, and aggressive Link-Time Optimization (LTO). Is highly compatible with source code originally written for GCC
Is the c + + library compatible with the gcc compiler?
The C++ library used with a C++ compiler includes the Standard C++ Library, with functionality defined in the C++ Standard, plus language runtime support. The runtime support is included in a C++ ABI, but there is no formal ABI for the Standard C++ Library.
Is there a gcc compatible compiler for clang?
Both a GCC-compatible compiler driver ( clang) and an MSVC-compatible compiler driver ( clang-cl.exe) are provided. You can get and build the source today. Some of the goals for the project include the following: Fast compiles and low memory use Utility and Applications: Modular library based architecture
Is the arm compiler 6 front end compatible with gcc?
The Arm Compiler 6 front-end technology with extended GCC compatibility means that not all legacy code written for Arm Compiler 5 can be directly built by the new toolchain. However, the code migration process is facilitated by a comprehensive Migration and Compatibility Guide and Arm’s expert technical support service.
Is the gcc compiler compatible with the c + + abi?
GCC’s -Wabi switch warns when G++ generates code that is probably not compatible with the C++ ABI. The C++ library used with a C++ compiler includes the Standard C++ Library, with functionality defined in the C++ Standard, plus language runtime support.
Is the gcc compiler compatible with c + + 17?
Version 7.1 has a C++ front end with experimental support for all of the the C++ 17 draft specification. The -std=c++1z and -std=gnu++1z options and the libstdc++ are supported, and the library has most C++17 draft library features implemented. The earlier GCC 6.1 release abided by the C++ 14 standard. [ The art of programming moves rapidly.
Is the llvm compiler system compatible with gcc?
The LLVM compiler system for C and C++ includes the following: Front-ends for C, C++, Objective-C, Fortran, etc based on the GCC 4.2 parsers. They support the ANSI-standard C and C++ languages to the same degree that GCC supports them. Additionally, many GCC extensions are supported.
Is the gcc compiler compatible with apple mac?
The GCC compiler has yet to receive Apple Silicon support, and that's led some to argue that anyone serious about scientific computing should avoid M1-based Mac models until the situation improves. Those behind the R programming language have confirmed the language runs well under emulation but isn't yet available to run natively on Apple ...
Is the oneko project compatible with gcc compiler?
The command below produces oneko executable on the majority of distributions. The same arguments will work with GCC compiler. Read the docs. Patch levels are used for versions compatible with the original oneko. The project will switch to SemVer for versioning after the first feature-breaking change.
Is the gnu compiler collection ( gcc ) compatible with dbx?
On MIPS, Alpha and System V Release 4 systems this option produces stabs debugging output that is not understood by DBX. On System V Release 4 systems this option requires the GNU assembler. Produce debugging information in stabs format (if that is supported), using GNU extensions understood only by the GNU debugger (GDB).
Is the gcc compiler compatible with c + + 98?
GCC implements the majority of C++98 ( export is a notable exception) and most of the changes in C++03. To select this standard in GCC, use one of the options -ansi , -std=c++98, or -std=c++03; to obtain all the diagnostics required by the standard, you should also specify -pedantic...
Is the cuda 10.2 compiler compatible with gcc?
According to the CUDA 10.2 System Requirements, Table 1, the nvcc compiler in CUDA 10 doesn't support the latest versions of GCC and Clang. At the time of writing, Ubuntu 20.04 doesn't appear in that list, but I can confirm nvcc supports the older GCC 8.4 and Clang 8.0 but not the default GCC 9.3 and Clang 9.0.
Is the gcc compiler compatible with constexpr std?
The reason is simple: No compiler so far supports the constexpr std::vector and std::string. In contrast, the GCC and the Microsoft Compiler support the constexpr algorithms of the STL. In my following example, I use instead of a constexpr std::vector a constexpr std::array.
Is the gcc compiler compatible with avx programs?
The problem started When i have updated the compiler up to 4.7 and 4.8.1 versions to support the 16-bit AVX2 intrinsics, which is not supported in gcc 4.6 Currently, the updated gcc version compiles both AVX and AVX2 programs properly.
