If you have AVX CPU and want to start learning AVX programming, then BASELIB offers various utilites to do just that via prnymm, dumpymm, clearymm and sse_flags routines. They are accessible in both binaries mode and source mode supplied in the attachment (Revision 2.4) in the above post.

Sample demo code (via binaries BASE3.DLL on 32-bit Windows with AVX support, using GCC as the linker)
Code: [Select]
;--------------------
;nasm -f win this.asm
;gcc -m32 this.obj base3.dll -s -o this.exe
;--------------------
global _WinMain@16

extern _clearymm
extern _dumpymm
extern _prnline

section .data align=32
w dq 10.23,11.43,12.54,17.95
x dq 89.54,98.14,55.16,19.11
y dq 45.12,65.22,14.17,29.16
z dq 56.33,51.01,54.86,28.54
a dq 00.00,05.00,00.00,00.00

section .text
_WinMain@16:
        push    ebp             ;C's standard prologue
        mov     ebp,esp
        call    _clearymm       ;YMMs are dirty
        vmovapd ymm4,[w]        ;data population
        vmovapd ymm5,[x]
        vmovapd ymm6,[y]
        vmovapd ymm7,[z]
        vmovapd ymm0,[a]
        mov     eax,1           ;option to view as packed quads
        call    _dumpymm        ;See initial population
        call    _prnline
        vdivpd  ymm1,ymm4,ymm0  ;perform an AVX packed division. YMM1 = YMM4 / YMM0
        mov     eax,1           ;See the result after division
        call    _dumpymm
        pop     ebp             ;Epilogue
        ret

The code above produces the following output
Code: [Select]
YMM0: 0.0|0.0|5.0|0.0   ;the YMM registers after data population
YMM1: 0.0|0.0|0.0|0.0
YMM2: 0.0|0.0|0.0|0.0
YMM3: 0.0|0.0|0.0|0.0
YMM4: 17.95|12.54|11.43|10.23
YMM5: 19.11|55.16|98.14|89.54
YMM6: 29.16|14.17|65.22|45.12
YMM7: 28.54|54.86|51.01|56.33

YMM0: 0.0|0.0|5.0|0.0   ;the YMM registers after packed divisions on four REAL8 data
YMM1: #|#|2.286|#
YMM2: 0.0|0.0|0.0|0.0
YMM3: 0.0|0.0|0.0|0.0
YMM4: 17.95|12.54|11.43|10.23
YMM5: 19.11|55.16|98.14|89.54
YMM6: 29.16|14.17|65.22|45.12
YMM7: 28.54|54.86|51.01|56.33

EDIT: Added the equivalent code for Linux32. Using BASE3.O and GCC as linker. Your CPU must have AVX support.
Code: [Select]
;--------------------
; nasm -f elf this.asm
; gcc -m32 this.o base3.o -s -o this
; ./this
;--------------------
global main

extern clearymm
extern dumpymm
extern prnline

section .data align=32
w dq 10.23,11.43,12.54,17.95
x dq 89.54,98.14,55.16,19.11
y dq 45.12,65.22,14.17,29.16
z dq 56.33,51.01,54.86,28.54
a dq 00.00,05.00,00.00,00.00

section .text
main:
push ebp ;C's standard prologue
mov ebp,esp
call clearymm ;YMMs are dirty
vmovapd ymm4,[w] ;data population
vmovapd ymm5,[x]
vmovapd ymm6,[y]
vmovapd ymm7,[z]
vmovapd ymm0,[a]
mov eax,1 ;option to view as packed quads
call dumpymm ;See initial population
call prnline

This example below demonstrates how one safely probe the system's kernel on Linux for any valuable information returned. Example, in accessing MMAP and MUNMAP, with dumpreg as the helper to verify values returned in RAX. dumpreg routine is accesible from base6.o

Code: [Select]
;-------------------------
;nasm -f elf64 this.asm
;ld this.o base6.o -o this (base6.o is from BASELIB)
;./this
;-------------------------
global _start

extern dumpreg ;from base6.o

section .text
_start:
mov r9,0 ;unsigned long off
mov r8,-1 ;unsigned long fd
mov r10,0x21 ;unsigned long flags
mov rdx,0x3 ;unsigned long prot
mov rsi,0x1000 ;unsigned long size
mov rdi,0 ;unsigned long addr
mov rax,9 ;mmap()
syscall
call dumpreg ;confirm return value in RAX (This is your new allocated area)

dealloc:
mov rsi,0x1000
mov rdi,rax
mov rax,11 ;munmap()
syscall
call dumpreg ;success RAX = 0

exit: xor edi,edi
mov eax,60
syscall

;Equates (from <sys/mmap.h>)
;MAP_SHARED equ 0x1
;MAP_ANONYMOUS  equ 0x20
;PROT_READ  equ 0x1
;PROT_WRITE equ 0x2

Once you are satisfied with all the information returned, then you can delete / disable the calls to base6.o (dumpreg). Output from the 2 dumpregs used above:

Code: [Select]
RAX|00007FE9C14D5000 RBX|0000000000000000 RCX|00000000004000D9  ;RAX points to new area allocated by MMAP.
RDX|0000000000000003 RSI|0000000000001000 RDI|0000000000000000
R8 |FFFFFFFFFFFFFFFF R9 |0000000000000000 R10|0000000000000021
R11|0000000000000202 R12|0000000000000000 R13|0000000000000000
R14|0000000000000000 R15|0000000000000000 RBP|0000000000000000
RSP|00007FFFF4343390 RIP|00000000004000D9 [UHex]

RAX|0000000000000000 RBX|0000000000000000 RCX|00000000004000ED  ;RAX indicates MUNMAP is successful. Memory allocated is returned.
RDX|0000000000000003 RSI|0000000000001000 RDI|00007FE9C14D5000
R8 |FFFFFFFFFFFFFFFF R9 |0000000000000000 R10|0000000000000021
R11|0000000000000206 R12|0000000000000000 R13|0000000000000000
R14|0000000000000000 R15|0000000000000000 RBP|0000000000000000
RSP|00007FFFF4343390 RIP|00000000004000ED [UHex]

You can further verify the newly allocated area using other advanced routines from BASELIB such as memview and memview2 by importing them via externs.

You can download BASELIB from the post above (revision 2.4) or from sourceforge

REVISION 2.7
Nov 19th, 2017

[1]Minor fixes to "sort_byte". Now sort signed bytes only
[2]Minor fixes to "sort_int" stack versions - One volatile register not saved
[3]"memview2" is switched with "memview" (64-bit)
[4]"memview2" is dropped - replaced by "memview" (32-bit)
[5]Minor fixes to mem_alloc/mem_free(Win64)

Introducing "cpulib.zip" - A partially ABI-compliant version of BASELIB. Callable from C. This is not compatible with BASELIB. For Win and Linux.

Download BASELIB. Or download directly below (revision 2.7)
