Conventions (used elsewhere as well): ; - _rm - real-mode function suffix. ; - _r86 - common real and virtual 8086 mode suffix. ; - _p16 - common 16-bit protected mode suffix. ; - _p32 - common 32-bit protected mode suffix. ; - _p64 - common 64-bit long mode suffix. ; - _pe16 - 16-bit unpaged protected mode suffix. ; - _pe32 - 32-bit unpaged protected mode suffix. ; - _pev86 - v8086 unpaged protected mode suffix. ; - _pp16 - 16-bit paged protected mode suffix. ; - _pp32 - 32-bit paged protected mode suffix. ; - _ppv86 - v8086 paged protected mode suffix. ; - _pae16 - 16-bit pae protected mode suffix. ; - _pae32 - 32-bit pae protected mode suffix. ; - _paev86- v8086 pae protected mode suffix. ; - _lm16 - 16-bit long mode suffix. ; - _lm32 - 32-bit long mode suffix. ; - _lm64 - 64-bit long mode suffix. ; ; The routines uses a custom register based calling convention for all cpu ; modes so that the users can template multi mode code. To make life easy for ; the programmer all registers are preserved with the exception of rflags and ; any return registers that may be used. Routines that does not return ; anything will only clobber eflags. ; ; The parameter register allocation order: ; rax, rdx, rcx, rbx, rsi, rdi(, r8, r9, r10, r11) ; ; When pointers are passed by 16-bit code, segments registers are allocated in ; the following order: ; ds, es, fs, gs. ; ; The return register allocations are: ; - edx:eax for 64-bit values in 16 and 32-bit mode, ; - eax for 32-bit, ; - ax for 16-bit, ; - al for 8-bit. ; ; Routines may use other calling convensions will be named differently. ; ; ; Copyright (C) 2007-2020 Oracle Corporation ; ; This file is part of VirtualBox Open Source Edition (OSE), as ; available from http://www.virtualbox.org.
