I'm trying to compile a simple project for cortex-m55, the project right now is pretty simple, just the main and CMSIS DSP and NN.
If I enable float-abi, no matter if hard, soft or softfp, I get the following compilation error:
../src/CMSIS/NN/Source/SoftmaxFunctions/arm_softmax_s8.c: In function 'arm_exp_on_negative_values_mve_32x4':
../src/CMSIS/NN/Source/SoftmaxFunctions/arm_softmax_s8.c:74:1: internal compiler error: in trunc_int_for_mode, at explow.cc:59
Hello, if you can find the compile command that's failing and add the -save-temps option, you should get a pre-processed .i file. Please can you upload that file along with the complete compile command that's failing?
Hi Alex,the command is this one (I'm using Embedded Eclipse)
arm-none-eabi-g++ -mthumb -mlittle-endian -mfloat-abi=hard -march=armv8.1-m.main+mve.fp+fp.dp -flax-vector-conversions -save-temps -Ofast -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections -g3 -Xlinker --gc-sections -Wl,-Map,"test.map" --specs=rdimon.specs -Wl,--start-group -lgcc -lc -lc -lm -lrdimon -Wl,--end-group -o "test.elf" $(OBJS) $(USER_OBJS) $(LIBS)
Hmm, that looks like a link step rather than a compile step. If you re-compile (and trigger the internal compiler error) you should get an arm_softmax_s8.i file. It would be useful if you could upload/attach that file (ideally with the failing command). Thanks
