define(`HOST_DOS64')

dnl  On DOS64 we always generate position-independent-code

dnl

define(`PIC')

define(`LEA',`

	lea	$1(%rip), $2

')

dnl  Usage: CALL(funcname)

dnl

dnl  Simply override the definition in x86_64-defs.m4.

define(`CALL',`call	GSYM_PREFIX`'$1')

dnl  Usage: JUMPTABSECT

define(`JUMPTABSECT', `RODATA')

dnl  Usage: JMPENT(targlabel,tablabel)

define(`JMPENT', `.long	$1-$2')

dnl  Usage: FUNC_ENTRY(nregparmas)

dnl  Usage: FUNC_EXIT()

dnl  FUNC_ENTRY and FUNC_EXIT provide an easy path for adoption of standard

dnl  ABI assembly to the DOS64 ABI.

define(`FUNC_ENTRY',

	`push	%rdi

	push	%rsi

	mov	%rcx, %rdi

ifelse(eval($1>=2),1,`dnl

	mov	%rdx, %rsi

ifelse(eval($1>=3),1,`dnl

	mov	%r8, %rdx

ifelse(eval($1>=4),1,`dnl

	mov	%r9, %rcx

')')')')

define(`FUNC_EXIT',

	`pop	%rsi

	pop	%rdi')

dnl  Target ABI macros.  For DOS64 we override the defaults.

define(`IFDOS',   `$1')

define(`IFSTD',   `')

define(`IFELF',   `')

dnl  Usage: PROTECT(symbol)

dnl

dnl  Used for private GMP symbols that should never be overridden by users.

dnl  This can save reloc entries and improve shlib sharing as well as

dnl  application startup times
