However, the assembler lacked support for marking + objects as using the VFP floating point format, and the + compiler was no properly passing the flag indicating "soft-VFP" + to the assembler. + + Unfortunately, this means that the linker will now consider + old (i.e. not marked "softvfp") NetBSD ARM ELF objects to be + incompatible with new (properly marked) objects. + + The problem will only manifest itself if you attempt to compile + a new program using the fixed toolchain, and link that program + against old libraries which do not have the proper "softvfp" + markings. ALL OF YOUR EXISTING BINARIES AND SHARED LIBRARIES + WILL CONTINUE TO WORK PROPERLY. + + The only work-around for the problem is to recompile all of + the libraries on the system. The easiest way to do this for + system libraries is to install a binary snapshot; there are + generally available on releng.netbsd.org.
