This change enables the use of PC-relative addressing with the -mcmodel=large option for PowerPC processors, including Power10 and Power11. Previously, PC-relative addressing was only supported for the -mcmodel=medium option. This update allows for greater flexibility in code generation for large models on these architectures.
