config/tc-aarch64.c: Avoid trying to parse a vector mov as immediate.
Parsing a vector mov instruction currently leads to a phantom undefined symbol being added to the symbol table. e.g.: .text mov x0, v0.D[0] Produces an undefined symbol called "v0.D". gas/ChangeLog: 2013-11-05 Will Newton <will.newton@linaro.org> PR gas/16103 * config/tc-aarch64.c (parse_operands): Avoid trying to parse a vector register as an immediate. gas/testsuite/ChangeLog: 2013-11-05 Will Newton <will.newton@linaro.org> * gas/aarch64/advsimd-mov-bad.d: New file. * gas/aarch64/advsimd-mov-bad.s: Likewise.
