I have a ARM920T (without fpu, kernel OABI)
I have (always in linux) a fpcrossarm compiler version 2.1.4 and one 2.3.1
(I don't know release).
I can compile with 2.1.4 with and without softfloat but 2.3.1 only without
softfloat.
I have compiled floattest with :
a) ppcrossarm 2.1.4 without CfSOFT --> result 0.150
b) ppcrossarm 2.1.4 with CfSOFT --> result 0.000
c) ppcrossarm 2.3.1 without CfSOFT --> result 0.150
but I can run datetostr_test without error.
