Alan Modra 2a50b40146 Fix tight loop on recursively-defined symbols ... This patch fixes a bug in GAS where the assembler enters a tight loop when attempting to resolve recursively-defined symbols, e.g. when trying to assemble "a=a". This is a regression introduced between binutils 2.32 and 2.33, by commit 1903f1385b * symbols.c (struct local_symbol): Update comment. (resolve_symbol_value): For resolved symbols equated to other symbols, verify that the referenced symbol is not a local_symbol before accessing sy_value. Don't leave symbol loops during finalize_syms resolution. * testsuite/gas/all/assign-bad-recursive.d: New test. * testsuite/gas/all/assign-bad-recursive.l: Error output for test. * testsuite/gas/all/assign-bad-recursive.s: Assembly for test. * testsuite/gas/all/gas.exp: Run it.		2020-05-15 18:21:07 +09:30
