swp{b} use is deprecated for this architecture

[Christoph Lipka]

when building 3rd party C++ software on the Pi (in this case, POV-Ray 3.7.0.RC6), I get lots of warnings from the assembler like the following:

g++ -DHAVE_CONFIG_H -I. -I../.. -I../.. -I../../source -I../../source -I../../source/base -I../../unix -I../../vfe -I../../vfe/unix -pthread -I/usr/include/OpenEXR -pthread -I/usr/include -pipe -Wno-multichar -Wno-write-strings -fno-enforce-eh-specs -s -O3 -ffast-math -pthread -MT sphsweep.o -MD -MP -MF .deps/sphsweep.Tpo -c -o sphsweep.o `test -f 'shape/sphsweep.cpp' || echo './'`shape/sphsweep.cpp

{standard input}:5248: Warning: swp{b} use is deprecated for this architecture

I guess this indicates some misunderstanding between the compiler and the assembler as to which instructions should be issued on the Pi and which shouldn't - something the 3rd party developers probably have no influence on, so these warnings should somehow be either fixed or suppressed.

Does this issue still occur? And with which version of the compiler?

Can you give a detailed step-by-step instruction on how to reproduce this?

This happened to me on Raspbian wheezy when building kodi. I have since upgraded to Raspbian jessie and the problem does not happen when building on jessie. I am not sure of the version of the compiler, I can research it if you need more info.
