<div>
<pre>llvm-mc rejected LDC and STC instruction for coprocessors P10 and P11
in generic coprocessor form:
LDC p10, ...
STC p11, ...
that used in open source libraries to enable VFP instruction
compilation for more targets.
Library may be compiled without VFP support enabled.
gcc compile this generic coprocessor form.
Problem in ARMAsmParser.cpp
P10 and P11 rejected in
static int MatchCoprocessorOperandName(StringRef Name, char CoprocOp)
// p10 and p11 are invalid for coproc instructions (reserved for FP/NEON)</pre>
