The text of this diagnostic was unnecessarily specific to the current ARM implementation of validateConstraintModifier, and it gave a potentially confusing suggestion for fixing the problem. The ARM-specific issue is not a big deal since that is the only target that currently does any checking of asm operand modifiers, but until my change in 183172 it was still wrong for output operands in the way that it referred to the value being truncated when put into a register, since output operands are retrieved from the registers instead of being put into them. The bigger problem is that its suggestion to "use a modifier" is wrong and confusing in the case where a "q" modifier is incorrectly used with an "r" constraint. In that case, the solution might well be to remove the modifier or perhaps change the constraint. It's better to just leave the diagnostic message more generic. llvm-svn: 183209 |
