Hello,
I am getting a hard exception fault when doing a divide on a int64_t on
a cortex-m3. Looking at the lss file, the compiler is doing the int64
divide using __aeabi_ldivmod which uses the instruction movlt. movlt is
not supported by the cortex-m3. How do I get gcc to use the right
version of __aeabi_ldivmod?
CFLAGS = -MMD -MP -march=armv7-m -mcpu=cortex-m3 -mfix-cortex-m3-ldrd
-mthumb -Wall -O3
LDFLAG = -march=armv7-m -mcpu=cortex-m3 -mfix-cortex-m3-ldrd -mthumb
-nostartfiles -Wl,--no-warn-mismatch -Wl,-dT sam3n.ld
I'm using arm-none-eabi-gcc v5.3.1
Jon
