The GNU Compiler Collection is shipped in version 9.
A detailed changelog on what changed in GCC 9 is available at https://gcc.gnu.org/gcc-9/changes.html
The compilers have been added to the SUSE Linux Enterprise Toolchain Module.
To use these compilers, install e.g. gcc9, gcc9-c++ and build with CC=gcc-9 CXX=g++-9 set.
For SUSE Linux Enterprise base products, the libstdc++6, libgcc_s1 and other compiler libraries have been switched from their gcc8 variants to their gcc9 variants.
Security issues fixed:
- CVE-2019-15847: Fixed a miscompilation in the POWER9 back end, that optimized multiple calls of the __builtin_darn intrinsic into a single call. (bsc#1149145) - CVE-2019-14250: Fixed a heap overflow in the LTO linker. (bsc#1142649)
Non-security issues fixed:
- Split out libstdc++ pretty-printers into a separate package supplementing gdb and the installed runtime. (bsc#1135254) - Fixed miscompilation for vector shift on s390. (bsc#1141897)
