ICE on ARM

[<pl...@pi...>]

Hi,

I'm trying to cross-compile gnuplot with maverick crunch fpu on ARM.

I have it building without the fpu code generation but it falls at the 
first hurdle if I use the FPU.

CFLAGS="-O2 -mcpu=ep9312 -mfpu=maverick -mfloat-abi=softfp" 
CXXFLAGS="-O2 -mcpu=ep9312 " ./configure --host=arm --prefix=/rar/root 
--without-x --without-pdf --without-cairo --without-documentation 
--disable-wxwidgets --without-lua --without-tutorial 
--disable-volatile-data  --disable-objects

make

Please submit a full bug report,


gen_tics seems to make heavy use of floats , is there any areas that may 
be a bit flakey on an unusual arch?

Clearly this is a major problem with the compiler itself but I'm 
wondering if there's anything likely to trip it up.

Thanks for any suggestions, Peter.
