The previous try was reverted because it just broke a bunch of tests, hiding the problem. - musttail behaves differently than tailcall at -O0. Some of the test run at -O0, so add separate effective target tests for musttail. - New effective target tests need to use unique file names to make dejagnu caching work - Change the tests to use new targets - Add a external_musttail test to check for target's ability to do tail calls between translation units. This covers some powerpc ABIs. gcc/testsuite/ChangeLog: PR testsuite/116080 * c-c++-common/musttail1.c: Use musttail target. * c-c++-common/musttail12.c: Use struct_musttail target. * c-c++-common/musttail2.c: Use musttail target. * c-c++-common/musttail3.c: Likewise. * c-c++-common/musttail4.c: Likewise. * c-c++-common/musttail7.c: Likewise. * c-c++-common/musttail8.c: Likewise. * g++.dg/musttail10.C: Likewise.
