aarch64: Fix MOVPRFX markup for bf16 conversions
bfcvt converts a .S input to a .H output, so any predicated movprfx
needs to operate on .S rather than .H. In common with SVE2 narrowing
top operations, bfcvtnt doesn't accept movprfx.
2020-01-31 Richard Sandiford <richard.sandiford@arm.com>
opcodes/
* aarch64-tbl.h (aarch64_opcode): Set C_MAX_ELEM for SVE bfcvt.
Remove C_SCAN_MOVPRFX for SVE bfcvtnt.
gas/
* testsuite/gas/aarch64/sve-bfloat-movprfx.s: Use .h rather than
.s for the movprfx.
* testsuite/gas/aarch64/sve-bfloat-movprfx.d: Update accordingly.
* testsuite/gas/aarch64/sve-movprfx_28.d,
* testsuite/gas/aarch64/sve-movprfx_28.l,
* testsuite/gas/aarch64/sve-movprfx_28.s: New test.
