The revision history of the FSF version of GCC between the EGCS split and the merge was retained on premerge-fsf-branch. That lets me see that this change was committed by Richard Kenner on 1998-10-04.
Thanks Ian. I contacted Richard but unfortunately he had no evidence of communicating with me back then. I'm considering porting the GCC 3.4.6 i370 to GCC 2.8.1 to give the new build process a more thorough workout, and also produce an executable for DOS/VS and z/VSE that doesn't exceed the system limitations so that it can be made relocatable. And also see what the memory requirements for a compile are, to see if it can fit into the approx 11 MB region that MVS 3.8j and DOS/VS allow. With 2.8.1 done, I would then forward port the build process to GCC 3.2.3 which is the most stable version. Then I should have all the i370 changes necessary, so it can come back to 3.4.6. Then I can make another attempt to get it into GCC 4.x. Last time I tried the cross-compiler went into a loop. So like before, it may require Dave Pitts to get the compiler proper working first before I add in my changes. BFN. Paul.
