Is > it correct? Library is not tied to any architecture, we took it from Newlib and merely adapted to eCos by studying the differences between "double" libs.. My standard testing is with Cortex-M3 settings -mcpu=cortex-m3 -mthumb -O2 which is default even for Kinetis (until we switch to gcc-4.6). >If so, should I have something special in eCos config to > build f-tests? Target is TWR-K60N512, Default template, just for practical reasons I'm changing startup type from ROM to SRAM. > Why I ask? All f-tests fail on eCos synthetic target > (d-tests are okay). True some tests fail when the result is supposed to be NaN such as acosf(1.2) The function returns 0 instad of NaN. I wander if it is a setting or the compiler option. The same behavior with both 4.3.2 and 4.6.3. I thought of some work-around but then decided to put it as-is - we need a solution rather than workaround. >Thus, I thought that I missed something in eCos > configuration. Could you provide your ecm-file? There isn't much for ecm file, only startup type. It would be good if you could try with some ARM target. FYI, example tests that fail on my platform are: asinf(x) |x| > 1, acosf(x) |x| > 1, logf(x) x < 0. Pass: tanf(), expf(), cosf(), etc...
