Hi Mathieu, Thanks for the review and testing. Here is the current status: - gn build failure with musl: fixed. - libgfortran QA failure (libcaf_shmem.a): fixed. - elfutils ptest failures (run-strip-nothing.sh, run-strip-g.sh): fixed. - libc-test static test failures (musl only): fixed. We also ran into a GCC 16 ICE during testing (extract_insn during IRA pass with UNSPEC_IEEE_MAX on i386 with -ffloat-store) and have reported it upstream:  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=125308 Still looking into the remaining failures. Will keep this thread updated and send v2 once everything is sorted. Thanks, Hemanth Kumar M D
