when we build with greenhills compiler, if the exception_common function is put into a separate section: ".text.exception_common", then the address of exception_common function is an even number, for example "0x16a6c", in this case, it will trigger the UsageFaults:INVSTATE error. The reason for this error is that in the GHS compiler, a section declared through the ".section" directive must specify at least the "a" attribute. Otherwise, this section will not be linked into the final file, and this is why the address of exception_common function is invalid. The following is the official explanation in the GHS compiler documentation: "The reason for this error is that in the GHS compiler, a section declared through the .section directive must specify at least the "a" attribute. Otherwise, this section will not be linked into the final file. The following is the official explanation in the documentation: "Sections that are intended be part of the final linked output should have at least the `a` attribute" and for GHS compiler, the .text section is recommended specify the attribute of `ax`.
