gas/config/tc-arm.c: Fix parsing of NEON load/store element sizes.
The existing code would accept VLD2.64 and similar undefined
instructions.
gas/ChangeLog:
2013-09-16 Will Newton <will.newton@linaro.org>
* config/tc-arm.c (do_neon_ld_st_interleave): Add constraint
disallowing element size 64 with interleave other than 1.
gas/testsuite/ChangeLog:
2013-09-16 Will Newton <will.newton@linaro.org>
* gas/arm/neon-ldst-es.d: Add VLD1.64 instructions.
* gas/arm/neon-ldst-es.s: Likewise.
* testsuite/gas/arm/neon-ldst-es-bad.d: New file.
* testsuite/gas/arm/neon-ldst-es-bad.l: Likewise.
* testsuite/gas/arm/neon-ldst-es-bad.s: Likewise.
