As I was checking news about GCC 8, I saw that they added support for the 2017 version of the C language (not C++17, really C17). But I can't find any information about it on Internet.
Is it a new ISO version like C11, or just a codename used by the GCC team for some corrections in their compiler ?
C17 is a “bugfix release” of the C standard how "M.S Chaudhari" noticed. However, there is very useful information prepared by Jens Gustedt the author of "Modern C" book.
He identified the following list of changes in C17 compared to C11:
atomics: initialization (7.17.2, 7.31.8), coherence requirements (5.1.2.4), fences (7.17.3 p11), functions or macros (7.17.1 p6), lockfree depends on type (7.17.5 p3), compare exchange compares memory and not value (7.17.7.3), atomic_flag (7.17.18).
threads: spurious failures (7.26.3.5 p2, 7.26.3.6 p2, 7.26.4.5 p3), synchronization (7.26.4 p1), thread specific storage (
tss_t) and thread exit (7.26.5 p3, 7.26.5.5, 7.26.6)alignment: fundamental alignment (6.2.8),
_Alignas(6.7.5),aligned_alloc(7.22.3.1)sequence points: full expressions (6.8 p4), full declarators (6.7..6 p3)
infinite loops (6.8.5 p6)
reserved identifiers (7.1.3)
domain or range errors (7.12.1),
