Missing .vectors section

Open kovmir opened this issue 1 month ago • 0 comments

Compiling with the first provided command does place .vectors atop:

$ arm-none-eabi-gcc -T link.ld -nostdlib main.o -o firmware.elf
$ arm-none-eabi-objdump -h firmware.elf | grep vectors
  0 .vectors      000001ac  08000000  08000000  00001000  2**2

Compiling with Makefile build command does not:

$ make
arm-none-eabi-gcc main.c -W -Wall -Wextra -Werror -Wundef -Wshadow -Wdouble-promotion -Wformat-truncation -fno-common -Wconversion -g3 -Os -ffunction-sections -fdata-sections -I. -mcpu=cortex-m4 -mthumb -mfloat-abi=hard -mfpu=fpv4-sp-d16  -Tlink.ld -nostartfiles -nostdlib --specs nano.specs -lc -lgcc -Wl,--gc-sections -Wl,-Map=firmware.elf.map -o firmware.elf
$ arm-none-eabi-objdump -h firmware.elf | grep vectors

Why?
