Inline Assembler Abilities

[Steve Hutchesson]

Kevin,

The problem with giving a complete listing of Intel mnemonics is one
of duplication, the Intel PIII manuals are exhaustive in the instruction
set definitions and as Intel are the processor manufacturer, these are
the correct manuals to use as reference for the mnemonics.
http://support.intel.com/design/pentiumiii/manuals/

The range is in the PBDLL60 manual under ASM with the following,

========================================================================
Identify an assembly-language statement. PowerBASIC's Inline Assembler
supports 8086/8088, 80286, 80386, 80486, Pentium, Floating-Point and MMX
opcodes.
========================================================================

This in fact says it all and answers both your question and Paul's.

Most of the instructions that are not available are those that require
lower than ring3 access privileges. About 2 years ago, Greg Turgeon
demonstrated a technique using,

! db <hex_opcode>

that allows the compiler to assemble an unsupported opcode. The hex
opcodes can be got from the Intel manuals.

To build the device drivers you appear to be interested in, Microsoft have
the various DDK's avaliable which are designed to do exactly what you
need.

Best of luck, its a really fun area.

Thanks Paul that is exactly what I was looking for.

Kevin,
The following is a list of opcodes etc. that I found PBCC1.0 recognises and a list of unimplemented standard Intel opcodes which don't work. I suspect the list is the same for PBDLL.

This list may be incomplete but I figured them out for myself. I hope it is of some use to you.

Paul.

Unimplemented op-codes? These need to be verified:
CMPXCHG8B,JCXZ (use JECXZ),LGDT,SGDT,LLDT,SLDT,LTR,STR,LIDT,SIDT,MOV (SYSTEM)?,LMSW,SMSW,
MOV (DEBUG)?,INVD,WBINVD,INVLPG,RSM,RDMSR,WRMSR,RDTSC,XOR,RET (USE RETN & RETF),FPREMI,FCOMI,
FUCOMI,FCOMIP,FUCOMIP

Implemented opcodes:
AAA,AAD,AAM,AAS,ADC,ADD,,AND,ARPL,BOUND,,BSF,BSR,BSWAP,BT,BTC,BTR,BTS,BYTE,CALL,CBW,CDQ,CH,CL,

Steve is correct - unfortunately PB/DLL cannot produce LE files (VxD / Kernal mode drivers). If you have to write a Ring-0 app you'll probably need to use VC or similar.

Kevin,

The compiler will handle all of the Intel mnemonics you mentioned but I
don't think you can write ring0 access software with it. The win 95 VxD
device drivers are in LE format while the compiler creates PE files. From
the documentation, it says it will handle all asm instructions including
MMX and FP. I don't know about some of the very late PII & PIII specific
ones.

I am not up to date on the later device drivers but they may be different
as they are not from memory, LE format files.

Perhaps one of the PowerBASIC technical people could help you with this
capacity but I doubt if it can be done.

Regards & good luck.

Does anyone know which assembly instructions the PB/DLL 6.0 compiler supports and which ones it does not.
i.e.
MOV
MOVSB
ADD
SUB
POPA
OUT
IN
OUTSB
OUTSW


Is it possible to use(In Ring 0):
LGDT -Load Global Descriptor Table
SGDT -Store Global Descriptor Table
With the PB/DLL compiler.


Thanks a bunch
Kevin
