This is Intel i386 or higher asm code version of ntdll.dll
The minium cpu req by reactos are : 486.
The asm src in this folder need nasm to be compile with.
1. Rename reactos/lib/ntdll/makefile to reactos/lib/ntdll/makefile.c
or make a backup up of it.
(it contain the C code version of ntdll makefile)
2. Copy reactos/lib/ntdll/nasm/makefile-asm to reactos/lib/ntdll/makefile
(it contain the asm verison of ntdll makefile, I need to change some
part to get the asm version be in use insted of the c version)
3. Now run reactos/make so u get the asm version of ntdll
Hope everyone like this asm optimze version.
but for momment are only thing optimze are
ntdll/rtl/mem.c
-----------------------------------------
RtlCompareMemory
RtlCompareMemoryUlong
RtlFillMemoryUlong
RtlMoveMemory
RtlZeroMemory
RtlFillMemory
(can make it lite faster not maxium optimze yet)
ntdll/rtl/RtlRandom.c
-----------------------------------------
RtlRandom
RtlUniform
SavedValue
info about ntdll/nasm/fixasm.bat
-----------------------------------------
delete all file that are not src or bat file
in the folder ntdll/nasm/
