Subject: * target.h (init_libfuncs): New hook. * target-def.h:
Default TARGET_INIT_BUILTINS and TARGET_INIT_LIBFUNCS to
hook_void_void. Add TARGET_INIT_LIBFUNCS to TARGET_INITIALIZER. *
builtins.c (default_init_builtins): Delete. * expr.h
(default_init_builtins): Delete prototype. * doc/tm.texi: Document
TARGET_INIT_LIBFUNCS and US_SOFTWARE_GOFAST. Tweak documentation of
TARGET_FLOAT_LIB_COMPARE_RETURNS_BOOL. Remove documentation of
INIT_TARGET_OPTABS, MULSI3_LIBCALL, DIVSI3_LIBCALL, UDIVSI3_LIBCALL,
MODSI3_LIBCALL, UMODSI3_LIBCALL, MULDI3_LIBCALL, DIVDI3_LIBCALL,
UDIVDI3_LIBCALL, MODDI3_LIBCALL, and UMODDI3_LIBCALL,
* Makefile.in (optabs.o): Depends on target.h.
* defaults.h: Provide default for FLOAT_LIB_COMPARE_RETURNS_BOOL.
* optabs.c: Include target.h.
(prepare_float_lib_cmp): No need for #ifdef around use of
FLOAT_LIB_COMPARE_RETURNS_BOOL.
(set_optab_libfunc): New function.
(init_optabs): Delete use of all *_LIBCALL defines.
Call targetm.init_libfuncs not INIT_TARGET_OPTABS.
* optabs.h: Prototype set_optab_libfunc.
* config.gcc: Remove all references to pa/long_double.h,
ia64/hpux_longdouble.h, and gofast.h.
(mips-*-*): When --enable-gofast, just add US_SOFTWARE_GOFAST
to tm_defines; don't set INIT_SUBTARGET_OPTABS or change tm_file.
* config/alpha/alpha.c, config/c4x/c4x.c, config/cris/cris.c
* config/frv/frv.c, config/h8300/h8300.c, config/i860/i860.c
* config/ia64/ia64.c, config/ip2k/ip2k.c, config/m68hc11/m68hc11.c
* config/mips/mips.c, config/pa/pa.c, config/rs6000/rs6000.c
* config/sparc/sparc.c, config/vax/vax.c:
Provide a definition for TARGET_INIT_LIBFUNCS. Where
necessary, include optabs.h, libfuncs.h, and/or config/gofast.h.
* config/alpha/unicosmk.h, config/alpha/vms.h, config/c4x/c4x.h
* config/avr/avr.h, config/cris/cris.h, config/frv/frv.h
* config/h8300/h8300.h, config/i860/i860.h, config/ip2k/ip2k.h
* config/iq2000/iq2000.h, config/m68hc11/m68hc11.h, config/mips/mips.h
* config/rs6000/aix.h, config/rs6000/sysv4.h, config/sparc/elf.h
* config/sparc/lite.h, config/sparc/netbsd-elf.h, config/sparc/sol2.h
* config/sparc/sparc.h, config/v850/v850.h, config/vax/vax.h
* config/vax/elf.h: Don't define or use INIT_TARGET_OPTABS,
INIT_SUBTARGET_OPTABS, or any *_LIBCALL macros.
* config/ia64/hpux.h: Redefine INTEL_EXTENDED_IEEE_FORMAT to 0.
Set TARGET_INIT_LIBFUNCS and FLOAT_LIB_COMPARE_RETURNS_BOOL here.
* config/pa/pa-hpux.h: Define LONG_DOUBLE_TYPE_SIZE,
HPUX_LONG_DOUBLE_LIBRARY, and FLOAT_LIB_COMPARE_RETURNS_BOOL here.
* config/ia64/hpux_longdouble.h, config/pa/long_double.h: Delete.
* config/rs6000/xcoff.h: Don't define RS6000_ITRUNC nor RS6000_UITRUNC.
* config/sparc/sparc.h: Default SUN_CONVERSION_LIBFUNCS and
SUN_INTEGER_MULTIPLY_64 to 0.
* config/sparc/sol2.h: Redefine SUN_CONVERSION_LIBFUNCS and
SUN_INTEGER_MULTIPLY_64 to 1.
* config/sparc/elf.h: Redefine SUN_CONVERSION_LIBFUNCS and
SUN_INTEGER_MULTIPLY_64 to 0.
* config/sparc/lite.h, config/sparc/liteelf.h, config/sparc/sp86x-elf.h:
Define US_SOFTWARE_GOFAST.
* config/vax/vax.h: Default TARGET_ELF to 0.
* config/vax/elf.h: Redefine TARGET_ELF to 1.
* config/gofast.h: Don't define any macros here. Provide one
static function, gofast_maybe_init_libfuncs, which does what
INIT_GOFAST_LIBFUNCS used to do but only if US_SOFTWARE_GOFAST
is already defined. Do not clear negation libfuncs. Do
not mess with HFmode, XFmode, or TFmode libfuncs.
* config/avr/avr.c (avr_init_once): #if 0 out; mark FIXME.
