2014-09-12Remove LIBGCC2_HAS_?F_MODE target macros.Joseph Myers4-34/+47
This patch removes the LIBGCC2_HAS_{SF,DF,XF,TF}_MODE target macros, replacing them by predefines with -fbuilding-libgcc, together with a target hook that can influence those predefines when needed. The new default is that a floating-point mode is supported in libgcc if (a) it passes the scalar_mode_supported_p hook (otherwise it's not plausible for it to be supported in libgcc) and (b) it's one of those four modes (since those are the modes for which libgcc hardcodes the possibility of support). The target hook can override the default choice (in either direction) for modes that pass scalar_mode_supported_p (although overriding in the direction of returning true when the default would return false only makes sense if all relevant functions are specially defined in libgcc for that particular target). The previous default settings depended on various settings such as LIBGCC2_LONG_DOUBLE_TYPE_SIZE, as well as targets defining the above target macros if the default wasn't correct. The default scalar_mode_supported_p only declares a floating-point mode to be supported if it matches one of float / double / long double. This means that in most cases where a mode is only supported conditionally in libgcc (TFmode only supported if it's the mode of long double, most commonly), the default gets things right. Overrides were needed in the following cases: * SFmode would always have been supported in libgcc (the condition was BITS_PER_UNIT == 8, true for all current targets), but pdp11 defaults to 64-bit float, and in that case SFmode would fail scalar_mode_supported_p. I don't know if libgcc actually built for pdp11 (and the port may well no longer be being used), but this patch adds a scalar_mode_supported_p hook to it to ensure SFmode is treated as supported. * Certain i386 and ia64 targets need the new hook to match the existing cases for when XFmode or TFmode support is present in libgcc. For i386, the hook can always declare XFmode to be supported - the cases where it's not are the cases where long double is TFmode, in which case XFmode fails scalar_mode_supported_p[*] - but TFmode support needs to be conditional. (And of the targets not defining LIBGCC2_HAS_TF_MODE before this patch, some defined LONG_DOUBLE_TYPE_SIZE to 64, so ensuring LIBGCC2_HAS_TF_MODE would always be false, while others did not define it, so allowing it to be true in the -mlong-double-128 case. This patch matches that logic, although I suspect all the latter targets would have been broken if you tried to enable -mlong-double-128 by default, for lack of the soft-fp TFmode support in libgcc, which is separately configured.) [*] I don't know if it's deliberate not to support __float80 at all with -mlong-double-128. In order to implement the default version of the new hook, insn-modes.h was made to contain macros such as HAVE_TFmode for each machine mode, so the default hook can contain conditionals on whether XFmode and TFmode exist (to match the hardcoding of a list of modes in libgcc). This is also used in fortran/trans-types.c; previously it had a conditional on defined(LIBGCC2_HAS_TF_MODE) (a bit dubious, since it ignored the value of the macro), which is replaced by testing defined(HAVE_TFmode), in conjunction with requiring targetm.libgcc_floating_mode_supported_p. (Fortran is testing something stronger than that hook: not only is libgcc support required, but also libm or equivalent. Thus, it has a test for ENABLE_LIBQUADMATH_SUPPORT in the case that the mode is TFmode and that's not the same as any of the three standard types. The old and new tests are intended to accept exactly the same set of modes for all targets.) Apart from the four target macros eliminated by this patch, it gets us closer to eliminating LIBGCC2_LONG_DOUBLE_TYPE_SIZE as well, though a few more places using that macro need changing first. Bootstrapped with no regressions on x86_64-unknown-linux-gnu; also built cc1 for crosses to ia64-elf and pdp11-none as a minimal test of changes for those targets. gcc: * target.def (libgcc_floating_mode_supported_p): New hook. * targhooks.c (default_libgcc_floating_mode_supported_p): New function. * targhooks.h (default_libgcc_floating_mode_supported_p): Declare. * doc/tm.texi.in (LIBGCC2_HAS_DF_MODE, LIBGCC2_HAS_XF_MODE) (LIBGCC2_HAS_TF_MODE): Remove.
