GCC 4.8 Release Brings Improved C++11, Optimizations
Posted by Michael Larabel on March 22, 2013
GCC 4.8 has been officially released today as the annual major update to the GNU Compiler Collection.
Prominent changes to GCC 4.8 include:
- Migrating the compiler's implementation to C++ rather than C.
- A brand new optimization level.
- ARM performance improvements.
- Initial compiler support for Intel Broadwell architecture and the new instruction set extensions it will present next year.
- CPU support for AMD Steamroller and Jaguar.
- Link-time optimization improvements.
- Runtime library improvements, a.k.a. libstdc++.
- ARM 64-bit / AArch64 support.
- Merging of AddressSanitizer and ThreadSanitizer, features previously found in LLVM that were developed by Google.
- Improved C++11 support and initial support for C++1y, the next C++ standard.
- Other new GCC 4.8 features.
The GCC 4.8 release was announced this morning at GNU.org. There's already been some GCC 4.8 compiler benchmarks at Phoronix, but a new round is forthcoming now that the official release is out in the wild.
