    • Type: Bug
    • Resolution: Unresolved
    • Priority: Low

      The attached test case is a simple program with two C files that each #include <math.h>.

      A minimal build works fine ...

      % tiarmclang -mcpu=cortex-m0 main.c test_func.c -Wl,-c

      Add the option -std=c89 ...

      % tiarmclang -mcpu=cortex-m0 -std=c89 main.c test_func.c -Wl,-c

      A similar result is seen with -std=c90 or -std=gnu90.
