armclang crashes when build debug version firmware

Oscar Huang

We have a firmware project, which can be built with DS-5. When building with DS-Gold (v2020.0), armclang crashes with debug configuration:

1. <eof> parser at end of file
2. Code generation
3. Running pass 'Function Pass Manager' on module '../HAL/PCIe/Serdes/plat/sys_timer.c'.
4. Running pass 'Legalizer' on function '@sys_timer_freq_get'
