[Vm-dev] gcc -E on the NoDbgRegParms issue

[gettimothy]

In the Cog/src/vm



running the -E option on gcc shows the NoDbgRegParms NOT being replaced in gcc3x-cointerp.c (along with some warnings that may be relevant, I don't know)




gcc -E gcc3x-cointerp.c -I /home/wm/usr/src/smalltalk/CMake.oscog/Cog/platforms/unix/vm -I /home/wm/usr/src/smalltalk/CMake.oscog/Cog/platforms/Cross/vm/ -I /home/wm/usr/src/smalltalk/CMake.oscog/Cog/build.linux32x86/squeak.cog.v3/build.assert/ -I ./ | cat > ~/gcc3x

The same command on cogit.c DOES show the replacement.


The question then becomes why is variable replacement  happening on the one and not the other.


I have been focusing on the preprocessor logic that sets NoDbgRegParms, but is there something else I may be overlooking?


thx.
