Hi,
I found that the bare-metal toolchains for aarch64 from Linaro could not seem to link objects to generate executable files successfully.
==================== Toolchain: https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch6...
==================== Testcase:
cat test.c
#include <stdio.h>
int main(int argc, char* argv[]) { printf("Hello World!\n"); return 0; }
aarch64-elf-gcc -o test test.c
Are you missing -specs=rdimon.specs or similar?
Thanks, Kugan

In addition, there was the same bug in 7.4.1-2019.02 version, but not in arm-eabi or armeb-eabi.
Is there anyone fixing this?
