Make soft-fp symbols into compat symbols for powerpc*-*-linux*.
Continuing preparations for implementing
TARGET_ATOMIC_ASSIGN_EXPAND_FENV for powerpc*-*-linux* soft-float and
e500, this patch makes soft-fp symbols used for those targets into
compat symbols when building with glibc >= 2.19, so that they are only
in shared libgcc for existing binaries requiring them, not in static
libgcc and not available for new links using shared libgcc. Instead,
new links will get the symbols from libc, which has exported all of
them since 2.19. (Actually all the symbols were exported from glibc
since 2.4, but some of them were exported by glibc as compat symbols
only - because of a confusion between deliberately present soft-fp
symbols and old accidental reexports of libgcc functions from glibc
2.0 - until 2.19.)
This allows user floating-point arithmetic to interoperate properly
with the state handled by <fenv.h> functions, whether software state
(for soft-float; TLS variables that don't form a public part of
glibc's ABI, so can only be accessed directly by functions within
glibc) or hardware state (for e500 - the copies of the soft-fp
functions in glibc being built to interoperate with the hardware state
whereas those in libgcc aren't). Previously only glibc's own
functions, and those operations done in hardware on e500, properly
worked with that state, not direct floating-point arithmetic
operations that were implemented in software.
The intended next step is the actual TARGET_ATOMIC_ASSIGN_EXPAND_FENV
implementation.
The test of glibc >= 2.19 uses the same --with-glibc-version configure
option as in the gcc/ directory (but differently implemented; in gcc/
the fallback is to examine headers to find the version, while in
libgcc/ we can use compile for the target and so use AC_COMPUTE_INT).
The TARGET_ATOMIC_ASSIGN_EXPAND_FENV implementation will also only do
anything for glibc >= 2.19, as it will depend on generating calls to
functions __atomic_feholdexcept __atomic_feclearexcept
__atomic_feupdateenv that were added in 2.19 for that purpose (even
for e500, inline code is not readily possible because of the need to
make prctl syscalls from the implementation of these functions).
In order to make symbols compat symbols, the soft-fp files need
wrapping with generated wrappers including asm .symver directives,
which need to name the symbol version in question. This is extracted
by an awk script from an intermediate stage of generating the .map
file for linking libgcc (that .map itself depends on the objects that
go into the library, so can't be used for this purpose as that would
mean a circular dependency); the extraction is not fully general
regarding the features available in .map generation, but suffices for
the present purpose.
It would make sense for hardfp.c symbols to be compat symbols as well
(in the cases where hardfp.c gets used, the functions in question
should not be used for new links), but this isn't required for the
present purpose, which is only concerned with ensuring that where
functions that should be affected by rounding modes or exceptions get
used, those functions are actually affected by those rounding modes or
exceptions.
Tested with no regressions with cross to powerpc-linux-gnu
(soft-float); c11-atomic-exec-5.c moves from UNSUPPORTED to FAIL, as
expected, now that floating-point arithmetic in user programs uses the
same state as <fenv.h> functions, so the fenv_exceptions test passes,
but TARGET_ATOMIC_ASSIGN_EXPAND_FENV isn't yet implemented. (For
e500, c11-atomic-exec-5.c was already FAILing, as enough operations
worked with the hardware state for the fenv_exceptions effective
target test to pass.) Also verified that the exported symbols and
versions are unchanged, with the expected symbols becoming compat
symbols at the same versions, and that with --with-glibc-version=2.18
the symbols remain normal rather than compat symbols.

Optimize powerpc*-*-linux* e500 hardfp/soft-fp use.
Continuing the cleanups of libgcc soft-fp configuration for powerpc*-*-linux* in preparation for implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for soft-float and e500, this patch optimizes the choice of which functions to build for the e500 cases. For e500v2, use of hardfp is generally right, except that calls to __unordsf2 and __unorddf2 are actually generated by GCC from __builtin_isunordered and so they need to be implemented with soft-fp to avoid recursively calling themselves. For e500v1, hardfp is right for SFmode (except for __unordsf2) but soft-fp for DFmode (and when using soft-fp, as usual it's best for the conversions between DFmode and integers all to come directly from soft-fp rather than some coming from libgcc2.c). Thus, new variables hardfp_exclusions and softfp_extras are added that configurations using t-hardfp and t-softfp can use to achieve the desired effect of selectively mixing the two sources of functions. Tested with no regressions for crosses to powerpc-linux-gnuspe (both e500v1 and e500v2); also checked that the same set of symbols and versions is exported from shared libgcc before and after the patch. * config/t-hardfp (hardfp_exclusions): Document new variable for user to define. (hardfp_func_list): Exclude functions from $(hardfp_exclusions). * config/t-softfp (softfp_extras): Document new variable for user to define.

Optimize powerpc*-*-linux* 32-bit classic hard/soft float hardfp/soft-fp use.
Continuing the cleanups of libgcc soft-fp configuration for powerpc*-*-linux* in preparation for implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for soft-float and e500, this patch optimizes the choice of which functions to build for the 32-bit classic hard-float and soft-float cases. (e500 will be dealt with in a separate patch which will need to add new features to t-hardfp and t-softfp; this patch keeps the status quo for e500.) For hard-float, while the functions in question are part of the libgcc ABI there is no need for them to contain software floating point code: no newly built code should use them, and if anything does use them it's most efficient (space and speed) for them to pass straight through to floating-point hardware instructions; this case is made to use t-hardfp to achieve that. For soft-float, direct use of soft-fp functions for operations involving DImode or unsigned integers is more efficient than using the libgcc2.c versions of those operations to convert to operations on other types (which then end up calling soft-fp functions for those other types, possibly more than once); this case is thus stopped from using t-softfp-excl. (A future patch will stop the e500 cases from using t-softfp-excl as well.) Tested with no regressions for crosses to powerpc-linux-gnu (soft float and classic hard float); also checked that the same set of symbols and versions is exported from shared libgcc before and after the patch. * configure.ac (ppc_fp_type): Set variable on powerpc*-*-linux*. * configure: Regenerate. * config.host (powerpc*-*-linux*): Use $ppc_fp_type to determine additions to tmake_file. Use t-hardfp-sfdf and t-hardfp instead of soft-fp for 32-bit classic hard float. Do not use t-softfp-excl for soft float. From-SVN: r216687 |

Do not build soft-fp code at all for powerpc64-linux-gnu.
When I added support for using soft-fp in libgcc <https://gcc.gnu.org/ml/gcc-patches/2006-03/msg00689.html>, libgcc configuration was still done in the gcc/ directory, meaning that the variables set in makefile fragments could not depend on the multilib being built. Thus, building the soft-fp code for powerpc64-linux-gnu was disabled in the same way as had been done with fp-bit: the code was built, but with #ifndef __powerpc64__ wrappers around it so that the resulting objects were empty. Now that libgcc configuration is done in the toplevel libgcc directory, such uses of softfp_wrap_start / softfp_wrap_end are better replaced by configure-time conditionals that determine whether to use soft-fp for a given multilib. This patch does so for powerpc*-*-linux*. The same would appear to apply to powerpc*-*-freebsd* (using rs6000/t-freebsd64), but I have not made any changes there. t-ppc64-fp is also used by AIX targets, but they don't use soft-fp anyway so the changes are of no consequence to them. The same principle of replacing softfp_wrap_start / softfp_wrap_end with configure-time conditionals also applies to softfp_exclude_libgcc2, which was intended for cases where soft-fp is being used on hard-float multilibs and so it is desirable on those multilibs for a few functions to come from libgcc2.c rather than soft-fp (but the soft-fp versions would be more efficient on soft-float multilibs). Now we have hardfp.c and t-hardfp, those are better to use in that case, to minimize the size of the bulk of the functions that are only present for ABI compatibility and should never be called by newly compiled code. I intend followup patches to switch 32-bit hard-float multilibs to use t-hardfp as far as possible (for all non-libgcc2.c operations for classic hard float; for all except __unord* for e500v2; for all SFmode operations except __unordsf2 for e500v1). After that will come making the soft-fp operations, in the remaining cases for which they are built because they are actually needed for code compiled by current GCC, into compat symbols when building for glibc 2.19 or later, so that the glibc versions (with exception and rounding mode support) get used instead (2.19 or later is needed for all the functions to be exported from glibc as non-compat symbols). In turn, that is required before implementing TARGET_ATOMIC_ASSIGN_EXPAND_FENV for soft-float and e500, as that can only be properly effective when GCC-compiled code is actually interoperating correctly with the exception and rounding mode state used by <fenv.h> functions. Tested with no regressions with cross to powerpc64-linux-gnu (in addition, verified that stripped libgcc_s.so.1 is identical before and after the patch). * config.host (powerpc*-*-linux*): Only use soft-fp for 32-bit configurations. * config/rs6000/t-ppc64-fp (softfp_wrap_start, softfp_wrap_end): Remove variables.

Remove LIBGCC2_LONG_DOUBLE_TYPE_SIZE target macro.
This patch removes the target macro LIBGCC2_LONG_DOUBLE_TYPE_SIZE. After recent changes, this macro was used in two ways in libgcc: to determine the mode of long double in dfp-bit.h, and to determine whether a particular mode has excess precision for use in complex multiplication. The former is concerned specifically with long double: it relates to use of strtold for converting between decimal and binary floating point. This is replaced by comparing __LDBL_MANT_DIG__ with the appropriate __LIBGCC_*_MANT_DIG__ macro. The latter is replaced __LIBGCC_*_EXCESS_PRECISION__ predefined macros. Remarks: * Comparing (__LDBL_MANT_DIG__ == __LIBGCC_XF_MANT_DIG__) is more fragile than it looks; it's possible for XFmode to have 53-bit mantissa (TARGET_96_ROUND_53_LONG_DOUBLE, on FreeBSD and DragonFlyBSD 32-bit), in which case such a comparison would not distinguish XFmode and DFmode as possible modes for long double. Fortunately, no target supporting that form of XFmode also supports long double = double (but if some target did, we'd need e.g. an additional macro giving the exponent range of each mode). Furthermore, this code doesn't actually get used for x86 (or any other target with XFmode support), because x86 uses BID not DPD and BID has its own conversion code (which handles conversions for both XFmode and TFmode without needing to go via strtold). And FreeBSD and DragonFlyBSD aren't among the targets with DFP support. So while in principle this code is fragile and it's a deficiency that it can't support both XFmode and TFmode at once (something that can't be solved with the string conversion approach without libc having TS 18661 functions such as strtof128), all these issues should not be a problem in practice. * If other cases of excess precision are supported in future, the code for defining __LIBGCC_*_EXCESS_PRECISION__ may need updating. Although the most likely such cases might not actually involve excess precision for any mode used in libgcc - FLT_EVAL_METHOD being 32 to do _Float16 arithmetic on _Float32 should have the effect of _Complex _Float16 arithmetic using __mulsc3 and __divsc3, rather than currently nonexistent __mulhc3 and __divhc3 as in bug 63250 for ARM. * As has been noted in the context of simultaneous support for __float128 and __ibm128 on Power, the semantics of macros such as LONG_DOUBLE_TYPE_SIZE are problematic because they rely on a poorly-defined precision value for floating-point modes (which seems to be intended as the number of significant bits in the representation, e.g. 80 for XFmode which may be either 12 or 16 bytes) uniquely identifying a mode (although defining an arbitrarily different value for one of the modes you wish to distinguish may work as a hack). It would be cleaner to have a target hook that gives a machine mode directly for float, double and long double, rather than going via these precision values. By eliminating all use of these macros (FLOAT_TYPE_SIZE, DOUBLE_TYPE_SIZE, LONG_DOUBLE_TYPE_SIZE) from code built for the target, this patch facilitates such a conversion to a hook (which I suppose would take some suitable enum as an argument to identify which of the three types to return a mode for). (The issue of multiple type support for DFP conversions would apply in that Power case. <https://gcc.gnu.org/ml/gcc-patches/2014-07/msg01084.html> doesn't seem to touch on it, but it would seem reasonable to punt on it initially as hard to fix. There would also be the issue of getting functions such as __powikf2, __mulkc3, __divkc3 defined, but that's rather easier to address.)

Remove LIBGCC2_TF_CEXT target macro.
This patch removes the (undocumented) LIBGCC2_TF_CEXT target macro, replacing it by -fbuilding-libgcc predefines (and thereby gets rid of another LIBGCC2_LONG_DOUBLE_TYPE_SIZE conditional, though some more patches are needed before that target macro can be eliminated). This macro indicated the suffix used on __builtin_huge_val, __builtin_copysign, __builtin_fabs built-in function names to produce the names for a given floating-point mode. Predefines are added for all floating-point modes supported for libgcc, not just TFmode. These are fully accurate for modes corresponding to float, double and long double. For other modes, the suffix for *constants* is determined by the targetm.c.mode_for_suffix hook (the limit to two possible suffixes 'w' and 'q' being hardcoded in various places). This is in fact the suffix for built-in functions as well where such functions exist. * For i386, the *q functions always exist (whether or not TFmode is used for long double). The *w functions never exist (but this doesn't matter for libgcc, since no i386 configuration treats XFmode as a supported scalar mode if long double is TFmode; if __float80 were to be supported for 64-bit Android, properly such functions ought to be added). * For ia64, the *q functions exist for non-HP-UX (under HP-UX, long double is TFmode, so they aren't needed). The *w functions never exist. This is an issue for this libgcc code for the XFmode complex functions in libgcc on HP-UX; as I understand it, right now those will accidentally be using TFmode versions of those three functions, so involving unnecessary conversions, while the sanity check on CEXT accidentally passes because all it tests is the sizes of the types. Because of the lack of 'w' functions, the patch uses 'l' when the constant suffix is 'w', matching what the existing libgcc code would do for IA64 HP-UX in that case. Ideally there would be generic code to create such built-in functions for all supported floating-point types. That may be something to consider if support for TS 18661-3 (standard bindings for IEEE 754-2008, defining names such as _Float128, and function names such as copysignf128) is added in future.

Remove LIBGCC2_HAS_?F_MODE target macros.
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.
