--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Sadly, neither of those regressions is fixed on i686-linux. Still the same /home/jakub/src/gcc/gcc/testsuite/gcc.dg/cast-function-1.c:49:1: error: non-trivial conversion in 'ssa_name' struct str_t int {} = arg_32; during GIMPLE pass: einline /home/jakub/src/gcc/gcc/testsuite/gcc.dg/cast-function-1.c:49:1: internal compiler error: verify_gimple failed 0x8ab2e63 verify_gimple_in_cfg(function*, bool) ../../gcc/tree-cfg.c:5427 0x8986378 execute_function_todo ../../gcc/passes.c:1983 0x89872ae do_per_function ../../gcc/passes.c:1638 0x89872ae execute_todo ../../gcc/passes.c:2037 for the cast-function-1.c one. But, you should be able to test it easily even on x86_64-linux, make check-gcc RUNTESTFLAGS='--target_board=unix\{-m32,-m64\} dg.exp=cast-function-1.c' still FAILs there too.
