After the Go 1.13 Beta 1 import, mainline bootstrap failed on Solaris as described in https://gcc.gnu.org/ml/gcc-patches/2019-09/msg00464.html. With the patch posted there, I managed to restore bootstrap. However, one libgo testcase regressed on both sparc and x86: go1: internal compiler error: in bind_field_or_method, at go/gofrontend/types.cc:11878 0x8b68e73 Type::bind_field_or_method(Gogo*, Type const*, Expression*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, Location) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/types.cc:11878 0x8ae942c Expression::lower(Gogo*, Named_object*, Statement_inserter*, int) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/expressions.h:929 0x8ae942c Lower_parse_tree::expression(Expression**) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:3090 0x8aaaffc Expression::traverse(Expression**, Traverse*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/expressions.cc:45 0x8ab63de Call_expression::do_traverse(Traverse*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/expressions.cc:10716 0x8ae93e6 Lower_parse_tree::expression(Expression**) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:3084 0x8aea784 Gogo::lower_expression(Named_object*, Statement_inserter*, Expression**) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:3158 0x8aeb368 Variable::lower_init_expression(Gogo*, Named_object*, Statement_inserter*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:7449 0x8b33647 Variable_declaration_statement::do_lower(Gogo*, Named_object*, Block*, Statement_inserter*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/statements.cc:304 0x8ae9abb Statement::lower(Gogo*, Named_object*, Block*, Statement_inserter*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/statements.h:310 0x8ae9abb Lower_parse_tree::statement(Block*, unsigned int*, Statement*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:3056 0x8ae9abb Lower_parse_tree::statement(Block*, unsigned int*, Statement*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:3033 0x8b34826 Statement::traverse(Block*, unsigned int*, Traverse*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/statements.cc:46 0x8aeba06 Block::traverse(Traverse*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:6879 0x8ae9a53 Lower_parse_tree::statement(Block*, unsigned int*, Statement*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:3045 0x8ae9a53 Lower_parse_tree::statement(Block*, unsigned int*, Statement*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:3033 0x8b34826 Statement::traverse(Block*, unsigned int*, Traverse*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/statements.cc:46 0x8aeba06 Block::traverse(Traverse*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:6879 0x8aeba06 Block::traverse(Traverse*) /vol/gcc/src/hg/trunk/local/gcc/go/gofrontend/gogo.cc:5779
Should be fixed by SVN revision 275648 (I forgot to add the PR reference to the commit message).
