Flat Assembler 1.67.29 (Default branch)
The flat assembler is a fast and efficient self-assembling 80x86 assembler for DOS, Windows, and Linux operating systems. It supports all 8086-80486/Pentium instructions with MMX, SSE, SSE2, SSE3, and 3DNow! extensions and x86-64 (both AMD64 and EM64T) instructions. It can produce output in binary, MZ, PE, COFF, or ELF format. It includes the powerful but easy-to-use macroinstruction support, and does multiple passes to optimize the instruction codes for size. The flat assembler is entirely written in assembly language. License: BSD License (revised) Changes:The optional output of symbolic information was added, and the tools that allow you to extract data from this file and show it in a human-readable form are provided. Several minor fixes and enhancements were applied at the same time.

1. Programming
Hi, folks,
I have a simple program main.c. The program is very simple, just for testing purpose. The program was proven correct by using "gcc".
Now I would compile it step by step from main.c to main.o. Here is what I did:
cpp main.c main.i <This step succeeded>
cc main.i -o... (5 Replies)

getisax - extract valid instruction set extensions SYNOPSIS
#include <sys/auxv.h> uint_t getisax(uint32_t *array, uint_t n); DESCRIPTION
The getisax() function sets the vector array of n 32-bit integers to contain the bits from the AV_xxx_yyy namespace of the given instruc- tion set architecture. Values for AV_xxx_yyy are as follows: SPARC AV_SPARC_MUL32 32x32-bit smul/umul is efficient AV_SPARC_DIV32 32x32-bit sdiv/udiv is efficient AV_SPARC_FSMULD fsmuld instruction is efficient AV_SPARC_V8PLUS V9 instructions available to 32-bit apps AV_SPARC_POPC popc instruction is efficient AV_SPARC_VIS VIS instruction set is supported AV_SPARC_VIS2 IS2 instruction set is supported x86 AV_386_FPU x87-style floating point AV_386_TSC rdtsc instruction AV_386_CX8 cmpxchg8b instruction AV_386_SEP sysenter and sysexit AV_386_AMD_SYSC AMD's syscall and sysret AV_386_CMOV conditional move instructions AV_386_MMX MMX instructions AV_386_AMD_MMX AMD's MMX instructions AV_386_AMD_3DNow AMD's 3Dnow! instructions AV_386_AMD_3DNowx AMD's 3Dnow! extended instructions AV_386_FXSR fxsave and fxrstor AV_386_SSE SSE instructions and regs AV_386_SSE2 SSE2 instructions and regs AV_386_PAUSE use pause instruction (in spin loops) AV_386_SSE3 SSE3 instructions and regs AV_386_MON monitor/mwait instructions RETURN VALUES
The getisax() function returns the number of array elements that contain non-zero values. EXAMPLES
Example 1: Use getisax() to determine if the SSE2 instruction set is present. In the following example, if the message is written, the SSE2 instruction set is present and fully supportred by the operating system. uint_t ui; (void) getisax(&ui, 1); if (ui & AV_386_SSE2) printf("SSE2 instruction set extension is present. "); ATTRIBUTES
