This makes attribute cleanup code work the same as gcc and also makes bound checking a very little bit faster. tcc.h: Add save_return_reg(CType *) and restore_return_reg(CType *) Change gfunc_epilog() to gfunc_epilog(Sym *) arm-gen.c: arm64-gen.c: c67-gen.c: i386-gen.c: il-gen.c: riscv64-gen.c: x86_64-gen.c: Move save and restore register around bound_local_delete call to save_return_reg and restore_return_reg. Pass func_type from gfunc_epilog to gen_bounds_epilog. tccgen.c: Call save_return_reg/restore_return_reg in try_call_scope_cleanup when RETURN is found. tccrun.c: Fix warning when bound checking not used. tests/tests2/101_cleanup.c tests/tests2/101_cleanup.expect Extra checks attribute cleanup save/restore registers. tests/tests2/Makefile: Fix when bound checking not used.
