I tested which code generates Delphi3 for stdcall procedures. It is more similar to code wich is generated with non-patched
fpc 1.1 for "default" (declared without any calling-convention-defining keyword) procedures: does not save registers edi, esi, ebx
(that's true also for export procedures). Btw, what is the mean to save these registers? I do'nt exclude that it can be useful but then,
I think, 'stdcall' supported with current FPC 1.1 is a special variant of stdcall which must have anoter name, e.g., fpccall. Or it is a
trick to solve some Win32 callbacks-related problems? Then at least please give a name to 'default anomymous stdcall'!
But please answer to my information: I don't see that you read it. Summary of my previous messages:
1) Is my $calling patch interesting for you?
2) Current 'Stdcall'-declared constructors are buggy (btw, Delphi 3.0 supports only register constructors) and need to be fixed.
3) Inheritance of cdecl methods is also buggy.
4) Evidently declared stdcall procedures/functions are not "pure" stdcalls in reality and differ from "default anonymous stdcalls".
