Hello,

Just tried to use 'saveregisters' flag in DLL library's function.

this code is generated at the end of that function: popl %ebx
popl %esi
popl %edi
movl %eax,28(%esp)
popal
nop
leave
ret

This is obviously incorrect since popal will destroy result in %eax. Also, some optimisation could be made if saveregisters declared: those 3 push/pops are not really needed.

Along with this I've encountered some problems using DLL calls in Delphi methods... Seems to be, Delphi needs all registers to be preserved during call or else afterwards some pointers are destroyed and normal accessing object's vars is impossible (it traps in fact). As a temporary measure I've used something like that:

asm pushad end; DLLCall(); asm popad end;

Of course, with 'saveregisters' this problem can be solved if the code generated for it was correct.

BTW, maybe it is possible to add implicit pushad/popad calls in exported DLL funcs/procedures? If not, then I dunno why you've included those implicit 3 push/pops...

Best regards,
Aleksey
