aarch64: Don't assert on long sysreg names
This patch fixes an assertion failure on long system register operands in the AArch64 backend. See the new testcase for an input which reproduces the issue. gas/ChangeLog: * config/tc-aarch64.c (parse_sys_reg): Don't assert when parsing a long system register. (parse_sys_ins_reg): Likewise. (sysreg_hash_insert): New. (md_begin): Use sysreg_hash_insert() to ensure all system registers are no longer than the maximum length at startup. * testsuite/gas/aarch64/invalid-sysreg-assert.d: New test. * testsuite/gas/aarch64/invalid-sysreg-assert.l: Error output. * testsuite/gas/aarch64/invalid-sysreg-assert.s: Input. include/ChangeLog: * opcode/aarch64.h (AARCH64_MAX_SYSREG_NAME_LEN): New.
