gcc does not reduce the function call to the result if called function is not static when using -O2, only with -O3, clang and msvc do the optimization also with -O2

gcc does not reduce to call result if called function is not static in -O2 (will do with -O2) clang and msvc does it also in -O2 regardless of the function beeing static or not can someone explain to me why the -O2 optimizer is not able(allowed) to reduce this small sample the same way as clang/m

Testsuite integration for devel/coarray_native

Hi, I'm currently trying to put together a testsuite for the shared coarray branch. What I have so far is a directory gcc/testsuite/gfortran.dg/caf-shared which contains the attached dejagnu file plus the test cases This works with the command make check-fortran RUNTESTFLAGS="cas.exp=num_ima
