This patch updates contrib/download_prerequisites to download newer versions (the latest) of GMP, MPFR and MPC.
Main reason is a newer MPFR that provides C23 functions, additionally, the usual bug fixes or the new "away from zero" rounding in MPC might turn out to be useful. GMP also claims better support for some newer archs. Current GCC mainline already uses the MPFR 4.2+ functions for (a)sinpi, (a)cospi, (a)tanpi, and atan2pi, where (e.g.) 'sinpi(n) == sin(n*pi)': In the middle end as C23 builtin and additionally in the gfortran FE as those are also F2023 functions. There are additional C23 functions that will profit from MPFR support, but still have to be added. See PR 118592 (esp. comment 2) for the list - and below for the list of new MPFR functions 4.2+ brings. Note: ISL (0.24, latest 0.27) and gettext (0.22, latest 0.26) have not been updated; that's deferred to a future patch (soon, if deemed useful, or eventually). See below for some details. * * * Remarks: * download_prerequisites uses http://gcc.gnu.org/pub/gcc/infrastructure/ i.e. before the commit, the new files have to be placed there. * download_prerequisites is just a convenience script; users could freely use a newer or older version of the libraries (or none for optional ones like ISL) - what counts is: https://gcc.gnu.org/install/prerequisites.html Still, it makes sense that it works for most or all out of the box, esp. on older, non-standard systems. * Newer ISL versions require C++17, such that a build will fail with older compiler like, e.g., GCC-10.5 fails (albeit some older ones work with -std=c++1y). - GCC currently requires an ISO C++14 compiler (>= GCC 5.4). As there are no ISL changes that seem to be extremely important, an update does not seem to be sensible. * Newer gettext version: Gettext 0.26 (released Jul 20, 2025) contains a long-overdue update of the gcc-internal-format and gfc-internal-format checkings, useful to avoid argument bugs in the .po translation. Thus, there is some merit in doing an update, but not in this patch - and some more testing/checking seems to be sensible before doing it. * For GMP, I see that for Fedora, a C23 patch exists for 'configure', but for SUSE not. It also seems to build fine with GCC 15 here, i.e. the patch does not seem to be required and the old, currently downloaded GMP has the same configure check, unsurprisingly. There are a few other changes to GMP in the distros, but none seem to be really affected by 6.2 → 6.3, but I might have missed something. MPFR and MPC do not seem to have any changes in distros. [As all libraries are out for a while, the hope is that serious build errors would have lead to a new minor release, but that's just a hope.] * * * The GMP, MPFR, MPC version, used for the patch and to be added to http://gcc.gnu.org/pub/gcc/infrastructure/ are: * GMP 6.3.0 (2023-07-30, latest) [currently: 6.2.0] - https://gmplib.org/ - For better compatibility, not the .xz file but the .bz2 file has been used → https://gmplib.org/download/gmp/ * MPFR 4.2.2 (2025-03-20, latest) [currently: 4.1.0]: - https://www.mpfr.org/mpfr-current/ * MPC 1.3.1 (December 2022, latest) [currently: 1.2.1]: - https://www.multiprecision.org/mpc/download.html - Requires GMP 5.0.0+ and MPFR 4.1.0+ * * * Testing: An in-tree bootstrap GCC mainline with only the three libraries suggested has been done on: * x86-64 GNU Linux with a GCC 15 system compiler + running the testsuite (which hopefully picked up the just build libraries and not the system's ones). * on cfarm13 5.10.0-32-amd64 with GCC 10.2.1 (Debian 11/bullseye) + a partial testsuite run * on cfarm70 4.9.0-19-amd64 (Debian 9.13 (stretch); gcc 6.3.0) successfully building the stage1 compiler but stopping half-way through stage1 library build. (Slow system!) Otherwise, on #gcc IRC on Tue Jul 15 2025: - Iain pointed out to the ISL issue and remarked: "AFAIK the other pre-reqs build fine in-tree (I've been using gmp-6.3, mpfr 4.2.1, mpc-1.2.1 and gettext-0.22.5) - but sure I tried mpc-1.3.1 on at least one system." * * * OK for mainline? (Requires a prior update of 'infrastructure'). * * * Tobias PS: CHANGES from the respective NEW files. I additionally note that MPFR's configure now uses '#include "gmp.c"' instead of '#include <gmp.h>' which together with other configure changes (see below) might actually improve the build experience. GMP 6.2.0 to 6.3.1 - from the NEWS file: BUGS FIXED * A possible overflow of type int is avoided for mpz_cmp on huge operands. * A possible error condition when a malformed file is read with mpz_inp_raw is now correctly handled. FEATURES * New public function mpz_prevprime, companion of the existing mpz_nextprime. * New documented pointer types mpz_ptr, mpz_srcptr, and similar for other GMP types. Refer to the manual for full list and suggested usage. These types have been present in gmp.h at least since GMP-4.0, but previously not advertised to users. * Support for 64-bit Arm under Macos. * Support for the loongarch64 CPU family. * Support for building with LTO, link-time optimisations. SPEEDUPS * New special code for base = 2 in mpz_powm reduces the average time for the functions that test primality. * Speedup for the function mpz_nextprime on large operands. * Speedup for multiplications (some sizes only) thanks to new internal functions to compute small negacyclic products. * Special assembly code for IBM z13 and later "mainframe" CPUs, resulting in a huge speedup. * Improved assembly for several 64-bit x86 CPUs, Risc-V, 64-bit Arm. MPFR 4.1.0 to 4.2.2 - from the NEWS file: - In order to resolve a portability issue with the _Float128 fallback to __float128 for binary128 support (e.g. with Clang and glibc 2.41), the prototypes of the corresponding conversion functions had to be changed, with _Float128 replaced by mpfr_float128, where mpfr_float128 is a macro defined as _Float128 by default. This changes neither the ABI nor the API (except that the end user of MPFR would need to define mpfr_float128 as the actual type for the binary128 format if this is not the standard _Float128 type). - Other bug fixes (see <https://www.mpfr.org/mpfr-4.2.1/#fixed> and/or the ChangeLog file). In particular, the formatted output functions behaved incorrectly with %c on the value 0; such a use is uncommon, but this bug may have security implications. - Improved MPFR manual. - Detect the use of GMP's buggy vsnprintf replacement at configure time. With it, the tests of "%a" will be disabled to avoid an assertion failure in the MPFR testsuite. A warning will be displayed in the configure output in such a case. - Bug fixes (see <https://www.mpfr.org/mpfr-4.2.0/#fixed> and/or the ChangeLog file). - Improved MPFR manual. - Configure tests: replaced the test of the link with GMP, in order to avoid the use of a function without a prototype (Autoconf issue), as this is obsolescent in ISO C. The new test should be more robust. - The "fondue savoyarde" release. - Binary compatible with MPFR 4.0.* and 4.1.*, though some minor changes in the behavior of the formatted output functions may be visible, regarded as underspecified behavior or bug fixes (see below). - New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu, mpfr_atanu and mpfr_atan2u. - New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi, mpfr_atanpi and mpfr_atan2pi. - New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and mpfr_compound_si. - New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for mpfr_pow_sj). - Bug fixes. In particular, for the formatted output functions (mpfr_printf, etc.), the case where the precision consists only of a period has been fixed to be like ".0" as specified in the ISO C standard, and the manual has been corrected and clarified. The macros of the custom interface have also been fixed: they now behave like functions (except a minor limitation for mpfr_custom_init_set). MPC 1.2.1 to 1.3.1 - from the NEWS file: - Bug fix: It is again possible to include mpc.h without including stdio.h. - New function: mpc_agm - New rounding modes "away from zero", indicated by the letter "A" and corresponding to MPFR_RNDA on the designated real or imaginary part. - New experimental ball arithmetic. - New experimental function: mpc_eta_fund - Bug fixes: - mpc_asin for asin(z) with small |Re(z)| and tiny |Im(z)| - mpc_pow_fr: sign of zero part of result when the base has up to sign the same real and imaginary part, and the exponent is an even positive integer - mpc_fma: the returned 'int' value was incorrect in some cases (indicating whether the rounded real/imaginary parts were smaller/equal/greater than the exact values), but the computed complex value was correct. - Remove the unmaintained Makefile.vc; build files for Visual Studio can be found at https://github.com/BrianGladman/mpc .
