That will break existing code and be incompatible with delphi. >> Things like the objects unit and FreeVision >> will then be unusable, without the compiler being able to warn/error you >> for that. > > Why ? Are these special ? They have special routines to call local procedures and therefor expect that the framepointer is the first parameter. >> Also generating code for cdecl on x86 will become more complex: >> >> push para1 >> .. >> push paraX >> if isoprocvar.framepointer<>nil then >> push parentfp >> call proc >> dec stack,parasize_on_the_stack-sizeof(parentfp) >> if isoprocvar.framepointer<>nil then >> dec stack sizeof(parentfp) > > But cdecl does not allow local functions at all, no ? > > You dont have local functions in C, no ? The compiler and also delphi accepts it and generates correct code. A quick 'fix' for this will then be to disallow cdecl in macpas mode. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
