2025-05-27libgcc: Add DPD support + fix big-endian support of _BitInt <-> dfp conversionsJakub Jelinek20-28/+654
The following patch fixes FAIL: gcc.dg/dfp/bitint-1.c (test for excess errors) FAIL: gcc.dg/dfp/bitint-2.c (test for excess errors) FAIL: gcc.dg/dfp/bitint-3.c (test for excess errors) FAIL: gcc.dg/dfp/bitint-4.c (test for excess errors) FAIL: gcc.dg/dfp/bitint-5.c (test for excess errors) FAIL: gcc.dg/dfp/bitint-6.c (test for excess errors) FAIL: gcc.dg/dfp/bitint-8.c (test for excess errors) FAIL: gcc.dg/dfp/int128-1.c (test for excess errors) FAIL: gcc.dg/dfp/int128-2.c (test for excess errors) FAIL: gcc.dg/dfp/int128-4.c (test for excess errors) on s390x-linux (with the 3 not yet posted patches). The patch does multiple things: 1) the routines were written for the DFP BID (binary integer decimal) format which is used on all arches but powerpc*/s390* (those use DPD - densely packed decimal format); as most of the code is actually the same for both BID and DPD formats, I haven't copied the sources + slightly modified them, but added the DPD support directly, + renaming of the exported symbols from __bid_* prefixed to __dpd_* prefixed that GCC expects on the DPD targets 2) while testing that I've found some big-endian issues in the existing support 3) testing also revealed that in some cases __builtin_clzll (~msb) was called with msb set to all ones, so invoking UB; apparently on aarch64 and x86 we were lucky and got some value that happened to work well, but that wasn't the case on s390x For 1), the patch uses two ~ 2KB tables to speed up the decoding/encoding. I haven't found such tables in what is added into libgcc.a, though they are in libdecnumber/bid/bid2dpd_dpd2bid.h, but there they are just huge and next to other huge tables - there is d2b which is like __dpd_d2bbitint in the patch but it uses 64-bit entries rather than 16-bit, then there is d2b2 with 64-bit entries like in d2b all multiplied by 1000, then d2b3 similarly multiplied by 1000000, then d2b4 similarly multiplied by 1000000000, then d2b5 similarly multiplied by 1000000000000ULL and d2b6 similarly multipled by 1000000000000000ULL. Arguably it can save some of the multiplications, but on the other side accesses memory which is unlikely in the caches, and the 2048 bytes in the patch vs. 24 times more for d2b is IMHO significant. For b2d, libdecnumber/bid/bid2dpd_dpd2bid.h has again b2d table like __dpd_b2dbitint in the patch, except that it has 64-bit entries rather than 16-bit (this time 1000 entries), but then has b2d2 which has the same entries shifted left by 10, then b2d3 shifted left by 20, b2d4 shifted left by 30 and b2d5 shifted left by 40. I can understand for d2b paying memory cost to speed up multiplications, but don't understand paying extra 4 * 8 * 1000 bytes (+ 6 * 1000 bytes for b2d not using ushort) just to avoid shifts. 2025-05-27 Jakub Jelinek <jakub@redhat.com> * config/t-softfp (softfp_bid_list): Don't guard with $(enable_decimal_float) == bid. * soft-fp/bitint.h (__bid_pow10bitint): For !defined(ENABLE_DECIMAL_BID_FORMAT) redefine to __dpd_pow10bitint.

2025-05-20libgcc: Small bitint_reduce_prec big-endian fixesJakub Jelinek1-5/+5
The big-endian _BitInt support in libgcc was written without any testing and so I haven't discovered I've made one mistake in it (in multiple places). The bitint_reduce_prec function attempts to optimize inputs which have some larger precision but at runtime they are found to need smaller number of limbs. For little-endian that is handled just by returning smaller precision (or negative precision for signed), but for big-endian we need to adjust the passed in limb pointer so that when it returns smaller precision the argument still contains the least significant limbs for the returned precision. 2025-05-20 Jakub Jelinek <jakub@redhat.com> * libgcc2.c (bitint_reduce_prec): For big endian __LIBGCC_BITINT_ORDER__ use ++*p and --*p instead of ++p and --p. * soft-fp/bitint.h (bitint_reduce_prec): Likewise.

2024-02-13libgcc: Fix UB in FP_FROM_BITINTJakub Jelinek1-1/+5
As I wrote earlier, I was seeing FAIL: gcc.dg/torture/bitint-24.c -O0 execution test FAIL: gcc.dg/torture/bitint-24.c -O2 execution test with the ia32 _BitInt enablement patch on i686-linux. I thought floatbitintxf.c was miscompiled with -O2 -march=i686 -mtune=generic, but it turned out to be UB in it. If a signed _BitInt to be converted to binary floating point has (after sign extension from possible partial limb to full limb) one or more most significant limbs equal to all ones and then in the limb below (the most significant non-~(UBILtype)0 limb) has the most significant limb cleared, like for 32-bit limbs 0x81582c05U, 0x0a8b01e4U, 0xc1b8b18fU, 0x2aac2a08U, -1U, -1U then bitint_reduce_prec can't reduce it to that 0x2aac2a08U limb, so msb is all ones and precision is negative (so it reduced precision from 161 to 192 bits down to 160 bits, in theory could go as low as 129 bits but that wouldn't change anything on the following behavior). But still iprec is negative, -160 here. For that case (i.e. where we are dealing with an negative input), the code was using 65 - __builtin_clzll (~msb) to compute how many relevant bits we have from the msb. Unfortunately that invokes UB for msb all ones. The right number of relevant bits in that case is 1 though (like for -2 it is 2 and -4 or -3 3 as already computed) - all we care about from that is that the most significant bit is set (i.e. the number is negative) and the bits below that should be supplied from the limbs below. So, the following patch fixes it by special casing it not to invoke UB. For msb 0 we already have a special case from before (but that is also different because msb 0 implies the whole number is 0 given the way bitint_reduce_prec works - even if we have limbs like ..., 0x80000000U, 0U the reduction can skip the most significant limb and msb then would be the one below it), so if iprec > 0, we already don't call __builtin_clzll on 0. 2024-02-13 Jakub Jelinek <jakub@redhat.com> * soft-fp/bitint.h (FP_FROM_BITINT): If iprec < 0 and msb is all ones, just set n to 1 instead of using __builtin_clzll (~msb).
2024-02-10libgcc: Fix a bug in _BitInt -> dfp conversionsJakub Jelinek3-3/+3
The ia32 _BitInt support revealed a bug in floatbitint?d.c. As can be even guessed from how the code is written in the loop, the intention was to set inexact to non-zero whenever the remainder after division wasn't zero, but I've ended up just checking whether the 2 least significant limbs of the remainder were non-zero. Now, in the dfp/bitint-4.c test in one case the remainder happens to have least significant 64 bits zero and then the higher limbs are non-zero; with 32-bit limbs that means 2 least significant limbs are zero and so the code acted as if it was exactly divisible. Fixed thusly. 2024-02-10 Jakub Jelinek <jakub@redhat.com> * soft-fp/floatbitintdd.c (__bid_floatbitintdd): Or in all remainder limbs into inexact rather than just first two. * soft-fp/floatbitintsd.c (__bid_floatbitintsd): Likewise. * soft-fp/floatbitinttd.c (__bid_floatbitinttd): Likewise.

2023-11-09libgcc: Add {unsigned ,}__int128 <-> _Decimal{32,64,128} conversion support ↵Jakub Jelinek12-0/+636
[PR65833] The following patch adds the missing {unsigned ,}__int128 <-> _Decimal{32,64,128} conversion support into libgcc.a on top of the _BitInt support (doing it without that would be larger amount of code and I hope all the targets which support __int128 will eventually support _BitInt, after all it is a required part of C23) and because it is in libgcc.a only, it doesn't hurt that much if it is added for some architectures only in GCC 15. Initially I thought about doing this on the compiler side, but doing it on the library side seems to be easier and more -Os friendly. The tests currently require bitint effective target, that can be removed when all the int128 targets support bitint. 2023-11-09 Jakub Jelinek <jakub@redhat.com> PR libgcc/65833 libgcc/ * config/t-softfp (softfp_bid_list): Add {U,}TItype <-> _Decimal{32,64,128} conversions. * soft-fp/floattisd.c: New file. * soft-fp/floattidd.c: New file. * soft-fp/floattitd.c: New file. * soft-fp/floatuntisd.c: New file. * soft-fp/floatuntidd.c: New file. * soft-fp/floatuntitd.c: New file. * soft-fp/fixsdti.c: New file. * soft-fp/fixddti.c: New file. * soft-fp/fixtdti.c: New file. * soft-fp/fixunssdti.c: New file. * soft-fp/fixunsddti.c: New file. * soft-fp/fixunstdti.c: New file. gcc/testsuite/ * gcc.dg/dfp/int128-1.c: New test. * gcc.dg/dfp/int128-2.c: New test. * gcc.dg/dfp/int128-3.c: New test. * gcc.dg/dfp/int128-4.c: New test.

2023-09-06libgcc _BitInt support [PR102989]Jakub Jelinek19-3/+2595
This patch adds the library helpers for multiplication, division + modulo and casts from and to floating point (both binary and decimal). As described in the intro, the first step is try to reduce further the passed in precision by skipping over most significant limbs with just zeros or sign bit copies. For multiplication and division I've implemented a simple algorithm, using something smarter like Karatsuba or Toom N-Way might be faster for very large _BitInts (which we don't support right now anyway), but could mean more code in libgcc, which maybe isn't what people are willing to accept. For the to/from floating point conversions the patch uses soft-fp, because it already has tons of handy macros which can be used for that. In theory it could be implemented using {,unsigned} long long or {,unsigned} __int128 to/from floating point conversions with some frexp before/after, but at that point we already need to force it into integer registers and analyze it anyway. Plus, for 32-bit arches there is no __int128 that could be used for XF/TF mode stuff. I know that soft-fp is owned by glibc and I think the op-common.h change should be propagated there, but the bitint stuff is really GCC specific and IMHO doesn't belong into the glibc copy. 2023-09-06 Jakub Jelinek <jakub@redhat.com> PR c/102989 libgcc/ * config/aarch64/t-softfp (softfp_extras): Use += rather than :=. * config/i386/64/t-softfp (softfp_extras): Likewise. * config/i386/libgcc-glibc.ver (GCC_14.0.0): Export _BitInt support routines. * config/i386/t-softfp (softfp_extras): Add fixxfbitint and bf, hf and xf mode floatbitint.

2023-03-10libgcc, i386: Add __fix{,uns}bfti and __float{,un}tibf [PR107703]Jakub Jelinek2-0/+90
While DI <-> BF conversions can be handled (and are) through DI <-> XF <-> BF and for narrower integral modes even sometimes through DF or SF, because XFmode has 64-bit mantissa and so all the DImode values are exactly representable in XFmode. That is not the case for TImode, and while e.g. the HF -> TI conversions are IMHO useless in libgcc, because HFmode has -65504.0f16, 65504.0f16 range, all the integers will be already representable in SImode (or even HImode for unsigned) and so I think HF -> DI -> TI conversions are faster and valid, BFmode has roughly the same range as SFmode and so we absolutely need the TI -> BF conversions to avoid double rounding. As for BF -> TI conversions, they can be either also implemented in libgcc, or they can be implemented (as done in this commit) as BF -> SF -> TI conversions with the same code generation used elsewhere, just doing the 16-bit left shift of the bits - I think we don't need to handle sNaNs during the BF -> SF part because SF -> TI (which is already a libcall too) will handle that too.

2023-03-06PR target/107299: Fix build issue when long double is IEEE 128-bitMichael Meissner1-0/+2
This patch updates the IEEE 128-bit types used in libgcc. At the moment, we cannot build GCC when the target uses IEEE 128-bit long doubles, such as building the compiler for a native Fedora 36 system. The build dies when it is trying to build the _mulkc3.c and _divkc3 modules. This patch changes libgcc to use long double for the IEEE 128-bit base type if long double is IEEE 128-bit, and it uses _Float128 otherwise. The built-in functions are adjusted to be the correct version based on the IEEE 128-bit base type used. While it is desirable to ultimately have __float128 and _Float128 use the same internal type and mode within GCC, at present if you use the option -mabi=ieeelongdouble, the __float128 type will use the long double type and not the _Float128 type. We get an internal compiler error if we combine the signbitf128 built-in with a long double type. I've gone through several iterations of trying to fix this within GCC, and there are various problems that have come up. I developed this alternative patch that changes libgcc so that it does not tickle the issue. I hope we can fix the compiler at some point, but right now, this is preventing people on Fedora 36 systems from building compilers where the default long double is IEEE 128-bit. 2023-03-06 Michael Meissner <meissner@linux.ibm.com> libgcc/ PR target/107299 * config/rs6000/_divkc3.c (COPYSIGN): Use the correct built-in based on whether long double is IBM or IEEE.

2022-10-14middle-end, c++, i386, libgcc: std::bfloat16_t and __bf16 arithmetic supportJakub Jelinek8-0/+558
Here is a complete patch to add std::bfloat16_t support on x86 (AArch64 and ARM left for later). Almost no BFmode optabs are added by the patch, so for binops/unops it extends to SFmode first and then truncates back to BFmode. For {HF,SF,DF,XF,TF}mode -> BFmode conversions libgcc has implementations of all those conversions so that we avoid double rounding, for BFmode -> {DF,XF,TF}mode conversions to avoid growing libgcc too much it emits BFmode -> SFmode conversion first and then converts to the even wider mode, neither step should be imprecise. For BFmode -> HFmode, it first emits a precise BFmode -> SFmode conversion and then SFmode -> HFmode, because neither format is subset or superset of the other, while SFmode is superset of both. expr.cc then contains a -ffast-math optimization of the BF -> SF and SF -> BF conversions if we don't optimize for space (and for the latter if -frounding-math isn't enabled either). For x86, perhaps truncsfbf2 optab could be defined for TARGET_AVX512BF16 but IMNSHO should FAIL if !flag_finite_math || flag_rounding_math || !flag_unsafe_math_optimizations, because I think the insn doesn't raise on sNaNs, hardcodes round to nearest and flushes denormals to zero. By default (unless x86 -fexcess-precision=16) we use float excess precision for BFmode, so truncate only on explicit casts and assignments. The patch introduces a single __bf16 builtin - __builtin_nansf16b, because (__bf16) __builtin_nansf ("") will drop the sNaN into qNaN, and uses f16b suffix instead of bf16 because there would be ambiguity on log vs. logb - __builtin_logbf16 could be either log with bf16 suffix or logb with f16 suffix. In other cases libstdc++ should mostly use __builtin_*f for std::bfloat16_t overloads (we have a problem with std::nextafter though but that one we have also for std::float16_t). 2022-10-14 Jakub Jelinek <jakub@redhat.com> gcc/ * tree-core.h (enum tree_index): Add TI_BFLOAT16_TYPE. * tree.h (bfloat16_type_node): Define. * tree.cc (excess_precision_type): Promote bfloat16_type_mode like float16_type_mode.

2015-09-28Update soft-fp from glibc.Joseph Myers81-136/+503
This patch updates the soft-fp code in libgcc from glibc. There are no changes here of significance to the use of soft-fp in GCC (and so no testsuite additions); it's simply an update to bring in the latest soft-fp version (which will also hopefully go into Linux 4.4 to replace the 15-year-old copy currently in Linux).
