ifdef(`PIC',

	`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

dnl

dnl  CAUTION: Do not put anything sensible here, like RODATA.  That works with

dnl  some Darwin tool chains, but silently breaks with other.  (Note that

dnl  putting jump tables in the text segment is a really poor idea for PC many

dnl  processors, since they cannot cache the same thing in both L1D and L2I.)

define(`JUMPTABSECT', `.text')

dnl  Usage: JMPENT(targlabel,tablabel)

ifdef(`PIC',

	`.set	$1_tmp, $1-$2

	.long	$1_tmp'

)')

dnl  Target ABI macros.  For Darwin we override IFELF (and leave default for

dnl  IFDOS and 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
