Hello,
--- quote ---
Is that with the script from Morten or with
#define WINAPI __stdcall __attribute__((__ms_hook_prologue__))
but only compiling user32?
--- quote ---
It should be obvious that I used Morten's script to insert as many NOPs needed
to move the PIC call beyond the 8 instruction barrier (have a look at the
examples I posted).
wine-1.3.24-42-g4ebbd0e unmodified:
kernel32 user32 gdi32 condition (cx < threshold)
--------------------------------------------------------------------
c1: 0x44 0x55 0x50 0x5F
c2: 0x2B 0x41 0x39 0x3C
c3: 0x00 0x00 0x00 0x5A
wine-1.3.24-42-g4ebbd0e with every public export hotpatchable
(__ms_hook_prologue__) in user32:
kernel32 user32 gdi32 condition (cx < threshold)
--------------------------------------------------------------------
c1: 0x44 0x54 0x50 0x5F
c2: 0x2B 0x3F 0x39 0x3C
c3: 0x00 0x00 0x00 0x5A
As already suspected - it doesn't have much effect on overall statistics
because for the majority of user32 exports one additional instruction is not
enough.
Regards
