It seems the problem is in the number of actual arguments.
Try to use
emit_callhelper(func);
instead of
emit_callhelper_prof2(func, CORINFO_PRUEBA, from,
to);

I tried with the emit_callhelper_prof2 macro inserting
a call to this function before the JitResult =
compileCEE_CALL();
void insertNativeCall(){
ULONG func = (ULONG) jitInfo->getHelperFtn
(CORINFO_PRUEBA);
UINT_PTR from = 0;
UINT_PTR to = 0;
emit_callhelper_prof2(func, CORINFO_PRUEBA, from,
to);
}
Where CORINFO_PRUEBA is a new helper I added in
CorInfoHelpFunc (corinfo.h) and is registered in
VMHELPDEF hlpFuncTable[] with the
JITHELPER(CORINFO_PRUEBA, prueba) macro.
the method prueba is declared as follows:
static void __stdcall Prueba();
and it only contains a printf.
I think everithing is right, however when I execute
buildall I get an Assert Failure several times with
the following message "ESP not correct on method exit.
Did you forget a leave?" in file fjitdef.h (method
void HELPER_CALL check_stack(int frameSize, BYTE* fp,
BYTE* sp{..}). If I select Retry and finish the build
process and execute clix I get the same Assert Failure
just after the method prueba has executed (just after
the printf message has appeared on the console). I
hope someone can tell me why this happens or what I am
doing wrong.
Thank you
