hi, i've got some more things to note. first, the issue is not related to x86_64 being the host machine - it also happens on i686/linux. next, i think (one of) the problem(s) is the use of [HOST_]WORDS_BIG_ENDIAN instead of [HOST_]FLOAT_WORDS_BIG_ENDIAN in llvm-convert.cpp (see patch below). this fixes single precision floating point but breaks double precision. for arm-softfloat-linux-gnu, FLOAT_WORDS_BIG_ENDIAN is true while WORDS_BIG_ENDIAN is false. as far as i've seen, there's only a single...

hi, i'm trying to make some experiments with the ARM backend (llvm 2.1) and therefore built an arm-softfloat-linux-gnu toolchain on x86_64 linux. however, the llvm-gcc frontend seems to cause troubles with single precision floating point values, i.e., they are not converted correctly to the particular target format (double precision works as expected). it seems the problem is related to
