--- Comment #16 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > Created attachment 33733 [details] > patch to fix darwin bootstrap > > With pseudo GOT register we don't need to set GOT register after any jump, > and therefore don't need "nonlocal_goto_receiver" and > "builtin_setjmp_receiver" > for i386. > > Please try attached patch (just removing "nonlocal_goto_receiver" and > "builtin_setjmp_receiver" from i386.md).
