--- Comment #3 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- Not reproduceable here with r245913. Is it gone with a recent Gcc? Gcc configured with --with-arch=zEC12 and compiled without explicit options: $ ~/src/gcc/install-master/bin/gcc ~/src/gcc/gcc/testsuite/gcc.target/mips/call-saved-7.c -march=zEC12 -S (Complains about missing main function without "-S")
