GCC 13.1 Released (UPDATED)

The GCC developers are proud to announce a new major GCC release, 13.1.

This release integrates a frontend for the Modula-2 language which

was previously available separately and lays foundation for a

frontend for the Rust language which will be available in a future

release.

Support for emitting the STABS debugging format was removed. GCC

supports DWARF in almost all configurations.

The C frontend got support for several C23 features, the C++ frontend

for C++23 features. The C++ standard library experimental support for

C++20 and C++23 was enhanced. For the C family of languages you can now

use -fstrict-flex-arrays[=level] to control the behavior for the various

legacy forms of specifying flexible array members.

GCCs static analyzer has been greatly improved with 20 new diagnostic

kinds.

Link-time optimization now makes automatic use of GNU makes jobserver

when that supports named pipes which it does starting with version 4.4.

It is no longer required to alter makefiles.

Support for new CPU features in the ARM, x86 family, RISC-V and LoongArch

were added. Notably RISC-V supports vector intrinsics as specified in

the 0.11 specification and OpenMP/OpenACC offloading to AMD Instinct MI200

series devices has been added.

Some code that compiled successfully with older GCC versions might require

source changes, see http://gcc.gnu.org/gcc-13/porting_to.html for

details.

Driving a leading free software project such as GCC would not be possible

without support from its many contributors.

Not only its developers, but especially its regular testers and users which

contribute to its high quality. The list of individuals

is too large to thank individually!
