...tor symbols look as follows: > > _ZVGQN2v__Z1fd > _ZVGDN2v__Z1ff > _ZVGQN4v__Z1ff Hi Francesco, The ARM AAPCS (A.2.1) says: "For C++ the mangled name for parameters is as though the equivalent type name was used." Clang is already able to mangle NEON vectors of any length (CXXNameMangler::mangleNeonVectorType), you should use that, as this is very likely to be compatible with other compilers as well. cheers, --renato

Hi Renato, The “u”, “v”, “l” mangling of parameters has already been agreed internally at ARM with the gcc team, and as Xinmin has pointed out, this is going to guarantee compa...

Hi Xinmin, I have updated the clang patch using the standard name mangling you suggested - I was not fully aware of the C++ mangling convention “_ZVG”. I am using “D” for 64-bit NEON and “Q” for 128-bit NEON, which makes NEON vector symbols look as follows: _ZVGQN2v__Z1fd _ZVGDN2v__Z1ff _ZVGQN4v__Z1ff Here “Q” means -> NEON 128-bit, “D” means -> NEON 64-bit Please notice that although
