PUSHALL/POPALL (PUSHAD/POPAD and flags for both x86 and x64)

On 64bit we dont have the PUSHAD/POPAD instructions so here is hopefully a manual solution. Im new to Purebasic so i welcome any feedback and hope i havent screwed this up!
As PUSHF/POPF are still supported perhaps its better to leave them out of this!

Code: Select all

Macro pushall       ;assumes EnableASM already set
    pushf           ;db 0x9C
  CompilerIf #PB_Compiler_Processor = #PB_Processor_x86
    pushad          ;db 0x60
  CompilerElseIf #PB_Compiler_Processor = #PB_Processor_x64    
    push rax        ;db 0x50
    push rcx        ;db 0x51
    push rdx        ;db 0x52               
    push rbx        ;db 0x53               
    push rbp        ;db 0x55               
    push rsi        ;db 0x56               
    push rdi        ;db 0x57               
    push r8         ;db 0x41,0x50          
    push r9         ;db 0x41,0x51          
    push r10        ;db 0x41,0x52          
    push r11        ;db 0x41,0x53          
    push r12        ;db 0x41,0x54          
    push r13        ;db 0x41,0x55          
    push r14        ;db 0x41,0x56          
    push r15        ;db 0x41,0x57            
  CompilerEndIf
EndMacro

Macro popall        ;assumes EnableASM already set

    pop r10         ;db 0x41,0x5A          
    pop r9          ;db 0x41,0x59          
    pop r8          ;db 0x41,0x58          
    pop rdi         ;db 0x5F

    popad           ;db 0x61
  CompilerEndIf
    popf            ;db 0x9D
