Hi, I am trying to get FP support working in a backend. This raised several questions which were promptly answered and after digging deeper I found the culprit. GCC is generating a call to floatunsihf when it needs to convert an unsigned integer to a float. And this call is being generated because I am compiling to a 16bit target, where floats are 32, meaning floats are HFmode.
Now, I read in http://gcc.gnu.org/wiki/Software_floating_point that soft-fp doesn't support 16bit targets, but (even if slow) does fp-bit support 16bit target? I just need a rudimentary floating point support (speed is not important) and I am trying to avoid assembler. Would I be able to get it working with fp-bit or maybe setting the FLOAT_TYPE_SIZE to something different than 32? -- PMatos
