cspec File Values and GCC?

[VGKintsugi]

I'm trying to debug a calling convention issue in my Sega Saturn (SH-1/SH-2) processor module. I have a gcc build chain (https://github.com/SaturnSDK/Saturn-SDK-GCC-SH2) and was able to successfully compile code for SH-2.

Given that I built gcc from source, is there any easy way to obtain the values (pointer sizes, calling convention, etc) directly from the gcc source tree itself? Thanks in advance.
