sqrt should be 0.5ulp precise, but the current implementation is less precise than that. The following patch uses the soft-fp code (like e.g. glibc for x86) for it if possible. I didn't want to replicate the libgcc infrastructure for choosing the right sfp-machine.h, so the patch just uses a single generic implementation. As the code is used solely for the finite positive arguments, it shouldn't generate NaNs (so the exact form of canonical QNaN/SNaN is irrelevant), and sqrt for these shouldn't produce underflows/overflows either, for < 1.0 arguments it always returns larger values than the argument and for > 1.0 smaller values than the argument. 2024-04-09 Jakub Jelinek <jakub@redhat.com> PR libquadmath/114623 * sfp-machine.h: New file. * math/sqrtq.c: Include from libgcc/soft-fp also soft-fp.h and quad.h if possible.

2024-04-03libquadmath: Don't assume the storage for __float128 arguments is aligned ↵Jakub Jelinek2-2/+3
[PR114533] With the register_printf_type/register_printf_modifier/register_printf_specifier APIs the C library is just told the size of the argument and is provided with a callback to fetch the argument from va_list using va_arg into C library provided memory. The C library isn't told what alignment requirement it has, but we were using direct load of a __float128 value from that memory which assumes __alignof (__float128) alignment. The following patch fixes that by using memcpy instead. I haven't been able to reproduce an actual crash, tried #include <quadmath.h> #include <stdlib.h> #include <stdio.h> int main () { __float128 r; int prec = 20; int width = 46; char buf[128]; r = 2.0q; r = sqrtq (r); int n = quadmath_snprintf (buf, sizeof buf, "%+-#*.20Qe", width, r); if ((size_t) n < sizeof buf) printf ("%s\n", buf); /* Prints: +1.41421356237309504880e+00 */ quadmath_snprintf (buf, sizeof buf, "%Qa", r); if ((size_t) n < sizeof buf) printf ("%s\n", buf); /* Prints: 0x1.6a09e667f3bcc908b2fb1366ea96p+0 */ n = quadmath_snprintf (NULL, 0, "%+-#46.*Qe", prec, r); if (n > -1) { char *str = malloc (n + 1); if (str) { quadmath_snprintf (str, n + 1, "%+-#46.*Qe", prec, r); printf ("%s\n", str); /* Prints: +1.41421356237309504880e+00 */ } free (str); } printf ("%+-#*.20Qe\n", width, r); printf ("%Qa\n", r); printf ("%+-#46.*Qe\n", prec, r); printf ("%d %Qe %d %Qe %d %Qe\n", 1, r, 2, r, 3, r); return 0; } In any case, I think memcpy for loading from it is right. 2024-04-03 Simon Chopin <simon.chopin@canonical.com> Jakub Jelinek <jakub@redhat.com> PR libquadmath/114533 * printf/printf_fp.c (__quadmath_printf_fp): Use memcpy to copy __float128 out of args. * printf/printf_fphex.c (__quadmath_printf_fphex): Likewise.

While investigating possible race conditions in the GCC testsuites caused by bufferization issues, I wanted to investigate workarounds similar to GDB's READ1 [1], and I noticed it was not always possible to override EXPECT when running 'make check'.

I was not able to test the patch for all the libraries updated here, but I confirmed it works as intended/needed for libstdc++. libatomic, libitm, libgomp already work as intended because their Makefiles do not have: MAKEOVERRIDES= Tested on (native) aarch64-linux-gnu, confirmed the patch introduces the behaviour I want in gcc, g++, gfortran and libstdc++.

2023-12-12libquadmath: Restore linking against -lm on most targets [PR112963]Jakub Jelinek3-2/+32
The r14-4825 change added AC_CHECK_LIBM to libquadmath configure.ac and replaced unconditional linking with -lm with linking with $(LIBM) determined by that. Unfortunately that broke bare metal targets because AC_CHECK_LIBM attempts to link against -lm and this was after (unconditional) GCC_NO_EXECUTABLES. Then r14-4863 partially reverted that change (no longer AC_CHECK_LIBM), but didn't revert the Makefile.am change of -lm to $(LIBM), which had the effect that libquadmath is not linked against -lm on any arch. That is a serious problem though e.g. on Linux, because libquadmath calls a few libm entrypoints and e.g. on powerpc64le the underlinking can cause crashes in IFUNC resolvers of libm. Instead of adding further reversion of the r14-4825 commit and use -lm unconditionally again, this patch adds an AC_CHECK_LIBM like substitutions with the *-ncr-sysv4.3* target handling removed (I think we don't support such targets, especially not in libquadmath) and with the default case replaced by simple using -lm. That is something in between using -lm unconditionally and what AC_CHECK_LIBM does if it would work on bare metal - we know from GCC 13 and earlier that we can link -lm on all targets libquadmath is built for, and just white list a couple of targets which we know don't have separate -lm and don't want to link against that (like Darwin, Cygwin, ...). 2023-12-12 Jakub Jelinek <jakub@redhat.com> PR libquadmath/112963 * configure.ac (LIBM): Readd AC_CHECK_LIBM-like check without doing AC_CHECK_LIB in it. * configure: Regenerated. * Makefile.in: Regenerated.

2023-10-22Config,Darwin: Allow for configuring Darwin to use embedded runpath.Iain Sandoe4-7/+226
Recent Darwin versions place contraints on the use of run paths specified in environment variables. This breaks some assumptions in the GCC build. This change allows the user to configure a Darwin build to use '@rpath/libraryname.dylib' in library names and then to add an embedded runpath to executables (and libraries with dependents). The embedded runpath is added by default unless the user adds '-nodefaultrpaths' to the link line. For an installed compiler, it means that any executable built with that compiler will reference the runtimes installed with the compiler (equivalent to hard-coding the library path into the name of the library). During build-time configurations any "-B" entries will be added to the runpath thus the newly-built libraries will be found by exes. Since the install name is set in libtool, that decision needs to be available here (but might also cause dependent ones in Makefiles, so we need to export a conditional). This facility is not available for Darwin 8 or earlier, however the existing environment variable runpath does work there. We default this on for systems where the external DYLD_LIBRARY_PATH does not work and off for Darwin 8 or earlier. For systems that can use either method, if the value is unset, we use the default (which is currently DYLD_LIBRARY_PATH). ChangeLog: * configure: Regenerate. * configure.ac: Do not add default runpaths to GCC exes when we are building -static-libstdc++/-static-libgcc (the default). * libtool.m4: Add 'enable-darwin-at-runpath'.

2023-08-07libtool.m4: fix the NM="/nm/over/here -B/option/with/path" caseNick Alcock1-7/+13
My previous nm patch handled all cases but one -- if the user set NM in the environment to a path which contained an option, libtool's nm detection tries to run nm against a copy of nm with the options in it: e.g. if NM was set to "nm --blargle", and nm was found in /usr/bin, the test would try to run "/usr/bin/nm --blargle /usr/bin/nm --blargle". This is unlikely to be desirable: in this case we should run "/usr/bin/nm --blargle /usr/bin/nm". Furthermore, as part of this nm has to detect when the passed-in $NM contains a path, and in that case avoid doing a path search itself. This too was thrown off if an option contained something that looked like a path, e.g. NM="nm -B../prev-gcc"; libtool then tries to run "nm -B../prev-gcc nm" which rarely works well (and indeed it looks to see whether that nm exists, finds it doesn't, and wrongly concludes that nm -p or whatever does not work). Fix all of these by clipping all options (defined as everything including and after the first " -") before deciding whether nm contains a path (but not using the clipped value for anything else), and then removing all options from the path-modified nm before looking to see whether that nm existed. NM=my-nm now does a path search and runs e.g. /usr/bin/my-nm -B /usr/bin/my-nm NM=/usr/bin/my-nm now avoids a path search and runs e.g. /usr/bin/my-nm -B /usr/bin/my-nm NM="my-nm -p../wombat" now does a path search and runs e.g. /usr/bin/my-nm -p../wombat -B /usr/bin/my-nm NM="../prev-binutils/new-nm -B../prev-gcc" now avoids a path search: ../prev-binutils/my-nm -B../prev-gcc -B ../prev-binutils/my-nm This seems to be all combinations, including those used by GCC bootstrap (which, before this commit, fails to bootstrap when configured --with-build-config=bootstrap-lto, because the lto plugin is now using --export-symbols-regex, which requires libtool to find a working nm, while also using -B../prev-gcc to point at the lto plugin associated with the GCC just built.)

2023-08-07libtool.m4: fix nm BSD flag detectionNick Alcock1-44/+45
Libtool needs to get BSD-format (or MS-format) output out of the system nm, so that it can scan generated object files for symbol names for -export-symbols-regex support. Some nms need specific flags to turn on BSD-formatted output, so libtool checks for this in its AC_PATH_NM. Unfortunately the code to do this has a pair of interlocking flaws: - it runs the test by doing an nm of /dev/null. Some platforms reasonably refuse to do an nm on a device file, but before now this has only been worked around by assuming that the error message has a specific textual form emitted by Tru64 nm, and that getting this error means this is Tru64 nm and that nm -B would work to produce BSD-format output, even though the test never actually got anything but an error message out of nm -B. This is fixable by nm'ing *nm itself* (since we necessarily have a path to it). - the test is entirely skipped if NM is set in the environment, on the grounds that the user has overridden the test: but the user cannot reasonably be expected to know that libtool wants not only nm but also flags forcing BSD-format output. Worse yet, one such "user" is the top-level Cygnus configure script, which neither tests for nor specifies any BSD-format flags. So platforms needing BSD-format flags always fail to set them when run in a Cygnus tree, breaking -export-symbols-regex on such platforms. Libtool also needs to augment $LD on some platforms, but this is done unconditionally, augmenting whatever the user specified: the nm check should do the same. One wrinkle: if the user has overridden $NM, a path might have been provided: so we use the user-specified path if there was one, and otherwise do the path search as usual. (If the nm specified doesn't work, this might lead to a few extra pointless path searches -- but the test is going to fail anyway, so that's not a problem.) (Tested with NM unset, and set to nm, /usr/bin/nm, my-nm where my-nm is a symlink to /usr/bin/nm on the PATH, and /not-on-the-path/my-nm where *that* is a symlink to /usr/bin/nm.) ChangeLog: * libtool.m4 (LT_PATH_NM): Try BSDization flags with a user-provided NM, if there is one. Run nm on itself, not on /dev/null, to avoid errors from nms that refuse to work on non-regular files. Remove other workarounds for this problem.
