GCC, the GNU Compiler Collection, supports a number of languages. This port installs the C, C++, and Fortran front ends as gcc15, g++15, and gfortran15, respectively. This is the first snapshot from trunk with the GCC 15 designation. It largely is a copy of lang/gcc14-devel.

Since the vDSO shared librares on Linux and FreeBSD are called
|
|
differently, the initialization order check fails on FreeBSD.
|
|
This patch fixes it by ignoring [vdso] instead of linux-vdso.so.
|
|
|
|
GCC gets the original file from the LLVM Project, so this patch should
|
|
probably be upstreamed directly to the LLVM Project rather than to GCC.
