Hi,
questions...
Is -CfSOFT supported on arm 2.0.5?
Do I need to add/define something when I build the crosscompiler to get
softfloat support?
Is changing system_arm_linux_info.endian to endian_big in
fpc/compiler/systems/i_linux.pas enough? I see in
references to {$if defined(CPUARM) and defined(FPUFPA)} and {$ifdef
FPC_LITTLE_ENDIAN} but no FPUSOFT or FPC_BIG_ENDIAN.
I have successfully made a crosscompiler for big endian arm and it
(ppcarm) compiles without problems and the resultant elf executes on the
arm.
But if I use any floating point it crashes out with...
$ ppcarm -XParm-linux- -Xs -XX -CpARMV5 -CfSOFT -n -B -vewhli \
-Fu~/arm-linux-fpc.i386-linux/lib/fpc/2.0.5/units/arm-linux/rtl \
floattest

b := 2.5;
c := a * b;
writeln(c);
end.
$ ppcarm -i
