This software is:



 *  d7avx - a helper (gcc frontend) for using SSE/AVX instructions with Delphi compilers not supporting SSE/AVX instructions

	uses MinGW GCC/ObjectDump to compile .c to .s and .s to .o with disassembly customized for delphi inclusion in asm statements

	tested only with MinGW GCC/ObjectDump

	c code - is compiled with GCC as a way to study generated assembly code with various optimization levels including SSE/AVX

	assembly code - is compiled, disassembled and customized for delphi inclusion as db statements (for when the instructions are unrecognized)


example of compiled, disassembled and customized assembly code for direct delphi inclusion:

    db      $c5,$fc,$10,$09           // vmovups ymm1,YMMWORD PTR [ecx]
    db      $c5,$fc,$10,$12           // vmovups ymm2,YMMWORD PTR [edx]
    db      $c5,$fc,$28,$d9           // vmovaps ymm3,ymm1
    db      $c5,$e4,$59,$da           // vmulps ymm3,ymm3,ymm2
    db      $c5,$fd,$70,$e3,$f5       // vpshufd ymm4,ymm3,0xf5
    db      $c5,$e4,$5c,$dc           // vsubps ymm3,ymm3,ymm4
    db      $c5,$e4,$54,$dd           // vandps ymm3,ymm3,ymm5
    db      $c5,$fd,$70,$d2,$b1       // vpshufd ymm2,ymm2,0xb1
    db      $c5,$ec,$59,$d1           // vmulps ymm2,ymm2,ymm1
    db      $c5,$fd,$70,$e2,$a0       // vpshufd ymm4,ymm2,0xa0
    db      $c5,$dc,$58,$e2           // vaddps ymm4,ymm4,ymm2
    db      $c5,$dc,$54,$e6           // vandps ymm4,ymm4,ymm6
    db      $c5,$dc,$56,$e3           // vorps ymm4,ymm4,ymm3
    db      $c5,$fc,$11,$20           // vmovups YMMWORD PTR [eax],ymm4
	

	the included .ini file holds the paths and commands used with gcc and objdump

 *  dbgavx - a helper for debugging XMM/YMM registers content with debuggers not supporting XMM/YMM registers

        used with any debugger for XMM/YMM and also MM/ST and general registers content inspection
	when the main debugger is on a breakpoint a thread in the debugee process can be suspended and a context extracted containing the register state for inspection
