The Flat Assembler docs explain how to work with the
various extended instructions:
From [ http://flatassembler.net/docs.php?article=manual
]:
Chapter 2 - Instruction Set
2.1 The x86 architecture instructions
2.1.1 Data movement instructions
2.1.2 Type conversion instructions
2.1.3 Binary arithmetic instructions
2.1.4 Decimal arithmetic instructions
2.1.5 Logical instructions
2.1.6 Control transfer instructions
2.1.7 I/O instructions
2.1.8 Strings operations
2.1.9 Flag control instructions
2.1.10 Conditional operations
2.1.11 Miscellaneous instructions
2.1.12 System instructions
2.1.13 FPU instructions
2.1.14 MMX instructions
2.1.15 SSE instructions
2.1.16 SSE2 instructions
2.1.17 SSE3 instructions
2.1.18 AMD 3DNow! instructions
2.1.19 The x86-64 long mode instructions
I looked the above over, and it looks like it will do everything
you are looking for. An additional advantage is that you can
easily go from inline assembly to 100% assembly language without
having to re-learn everything.
I also noted that PureBasic has a console mode, which is an
im****tant feature for the kinds of things I do, such as writing
a program that controls an automated assembly line with the only
user interface being a simple status screen.
There are some PureBasic limitations that may bother some folks;
http://www.purebasic.com/do***entation/reference/variables.html
says that PureBasic sup****ts the following data types:
Byte | 8 bit signed fixed | -128 to +127
Character | 8 bit | 65,535 different characters
Unicode Char. | 16 bit | 255 different characters
Word | 16 bit signed fixed | -32,768 to +32,767
Long | 32 bit signed fixed | -2,147,483,648 to +2,147,483,647
Quad | 64 bit signed fixed | -9.22x10^18 to +9.22x10^18
Float | 32 bit IEEE 754 float | 8.43x10^-37 to 3.40x10^38
Double | 64 bit IEEE 754 float | 4.19x10^-307 to 1.79x10^308
String |
Fixed String |
Unless the above URL is wrong, notably lacking are:
8 bit unsigned fixed | 0 to 255
16 bit unsigned fixed | 0 to 65,535
32 bit unsigned fixed | 0 to 4,294,967,295
80 bit IEEE 754 float | 3.4x10^-4932 to 1.2x10^4932
Currency | -9.22x10^14 to +9.22x10^14
Extended-currency | -9.22x10^16 to +9.22x10^16
All of which are available in PowerBASIC, along with more
exotic data types such as Variants and GIUDs.
PowerBASIC, on the other hand, is far more limited in what
you can do with inline assembly. As do***ented in
http://www.powerbasic.com/sup****t/help/pbcc/asm_statement.htm
"PowerBASIC's Inline Assembler sup****ts 8086/8088, 80286, 80386,
80486, Pentium, Floating-Point and MMX instructions." I don't
see any sup****t for SSE of any kind.
FreeBASIC uses GAS/AS (the GCC assembler).
The newest version of the AS/GAS manual I could find (2002) says:
8.12.9 Intel's MMX and AMD's 3DNow! SIMD Operations
as' sup****ts Intel's MMX instruction set (SIMD instructions
for integer data), available on Intel's Pentium MMX processors
and Pentium II processors, AMD's K6 and K6-2 processors, Cyrix'
M2 processor, and probably others. It also sup****ts AMD's 3DNow!
instruction set (SIMD instructions for 32-bit floating point data)
available on AMD's K6-2 processor and possibly others in the
future. Currently, `as' does not sup****t Intel's floating point
SIMD, Katmai (KNI). [Later renamed SSE].
So no SSE/SSE2/SSE3 for FreeBASIC users... :(
One really interesting feature of FreeBASIC is that it is written
in FreeBASIC. This means that a BASIC programmer can extend the
language. fix bugs, and in general participate in the Open Source
development process without having to use C.
My wish list includes a BASIC compiler that lets me enter x86
System Management Mode using inline assembly. <grin>
