Ada: Add LoongArch support to libgnat's object file reader
GCC's Ada library now supports reading object files for the LoongArch architecture.
The GNU Ada compiler’s runtime library (libgnat) has been updated to include support for the LoongArch architecture in its object file reader. This enables libgnat to correctly process and interpret object files generated for LoongArch, facilitating the use of Ada on this new platform.
In Details
The s-objrea.ads and s-objrea.adb files within GCC's libgnat component now recognize the EM_LOONGARCH ELF machine type. This involves updating the Object_Arch enumeration and handling LoongArch's specific address reading conventions in the Read_Address function, as well as integrating it into the ELF_Ops.Initialize logic. This expands libgnat's cross-architecture capabilities for object file introspection.
