2020-02-12Use a non-empty test program to test ability to link.Sandra Loosemore
On bare-metal targets, I/O support is typically provided by a BSP and requires a linker script and/or hosting library to be specified on the linker command line. Linking an empty program with the default linker script may succeed, however, which confuses libstdc++ configuration when programs that probe for the presence of various I/O features fail with link errors. 2020-02-12 Sandra Loosemore <sandra@codesourcery.com> PR libstdc++/79193 PR libstdc++/88999 config/ * no-executables.m4: Use a non-empty program to test for linker support. libgcc/ * configure: Regenerated. libgfortran/ * configure: Regenerated. libiberty/ * configure: Regenerated. libitm/ * configure: Regenerated. libobjc/ * configure: Regenerated. libquadmath/ * configure: Regenerated. libssp/ * configure: Regenerated. libstdc++v-3/ * configure: Regenerated.

Provide means, in the form of a `--with-toolexeclibdir=' configuration option, to override the default installation directory for target libraries, otherwise known as $toolexeclibdir. This is so that it is possible to get newly-built libraries, particularly the shared ones, installed in a common place, so that they can be readily used by the target system as their host libraries, possibly over NFS, without a need to manually copy them over from the currently hardcoded location they would otherwise be installed in.

2018-11-07Update libquadmath fmaq from glibc, fix nanq issues.Joseph Myers
This patch extends update-quadmath.py to update fmaq from glibc. The issue in that function was that quadmath-imp.h had a struct in a union with mant_high and mant_low fields (up to 64-bit) whereas glibc has mantissa0, mantissa1, mantissa2 and mantissa3 (up to 32-bit). The patch changes those fields to be the same as in glibc, moving printf / strtod code that also uses those fields back to closer to the glibc form. This allows fmaq to be updated automatically from glibc (which brings in at least one bug fix from glibc from 2015). nanq was also using the mant_high field name, and had other issues: it only partly initialized the union from which a value was returned, and setting mant_high to 1 meant a signaling NaN would be returned rather than a quiet NaN. This patch fixes those issues as part of updating it to use the changed interfaces (but does not fix the issue of not using the argument). Bootstrapped with no regressions on x86_64-pc-linux-gnu. * quadmath-imp.h (ieee854_float128): Use mantissa0, mantissa1, mantissa2 and mantissa3 fields instead of mant_high and mant_low. Change nan field to ieee_nan. * update-quadmath.py (update_sources): Also update fmaq.c. * math/nanq.c (nanq): Use ieee_nan field of union. Zero-initialize f. Set quiet_nan field. * printf/flt1282mpn.c, printf/printf_fphex.c, strtod/mpn2flt128.c, strtod/strtoflt128.c: Use mantissa0, mantissa1, mantissa2 and mantissa3 fields. Use ieee_nan and quiet_nan field. * math/fmaq.c: Regenerate from glibc sources with update-quadmath.py. From-SVN: r265874
2018-11-05Update most of libquadmath/math/ from glibc, automate update (PR ↵Joseph Myers
libquadmath/68686). libquadmath sources are mostly based on glibc sources at present, but derived from them by a manual editing / substitution process and with subsequent manual merges. The manual effort involved in merges means they are sometimes incomplete and long-delayed. Since libquadmath was first created, glibc's support for this format has undergone significant changes so that it can also be used in glibc to provide *f128 functions for the _Float128 type from TS 18661-3. This makes it significantly easier to use it for libquadmath in a more automated fashion, since glibc has a float128_private.h header that redefines many identifiers as macros as needed for building *f128 functions. Simply using float128_private.h directly in libquadmath, with unmodified glibc sources except for changing function names in that one header to be *q instead of *f128, would be tricky, given its dependence on lots of other glibc-internal headers (whereas libquadmath supports non-glibc systems), and also given how some libm functions in glibc are built from type-generic templates using a further set of macros rather than from separate function implementations for each type. So instead this patch adds a script update-quadmath.py to convert glibc sources into libquadmath ones, and the script reads float128_private.h to identify many of the substitutions it should make. quadmath-imp.h is updated with various new internal definitions, taken from glibc as needed; this is the main place expected to need updating manually when subsequent merges from glibc are done using the script. No attempt is made to make the script output match the details of existing formatting, although the differences are of a size that makes a rough comparison (ignoring whitespace) possible. Two new public interfaces are added to libquadmath, exp2q and issignalingq, at a new QUADMATH_1.2 symbol version, since those interfaces are used internally by some of the glibc sources being merged into libquadmath; although there is a new symbol version, no change however is made to the libtool version in the libtool-version file. Although there are various other interfaces now in glibc libm but not in libquadmath, this patch does nothing to add such interfaces (although adding many of them would in fact be easy to do, given the script). One internal file (not providing any public interfaces), math/isinf_nsq.c, is removed, as no longer used by anything in libquadmath after the merge. Conditionals in individual source files on <fenv.h> availability or features are moved into quadmath-imp.h (providing trivial macro versions of the functions if real implementations aren't available), to simplify the substitutions in individual source files. Note however that I haven't tested for any configurations lacking <fenv.h>, so further changes could well be needed there. Two files in libquadmath/math/ are based on glibc sources but not updated in this patch: fmaq.c and rem_pio2q.c. Both could be updated after further changes to the script (and quadmath-imp.h as needed); in the case of rem_pio2q.c, based on two separate glibc source files, those separate files would naturally be split out into separate libquadmath source files in the process (as done in this patch with expq_table.h and tanq_kernel.c, where previously two glibc source files had been merged into one libquadmath source file). complex.c, nanq.c and sqrtq.c are not based on glibc sources (though four of the (trivial) functions in complex.c could readily be replaced by instead using the four corresponding files from glibc, if desired). libquadmath also has printf/ and strtod/ sources based on glibc, also mostly not updated for a long time. Again the script could no doubt be made to generate those automatically, although that would be a larger change (effectively some completely separate logic in the script, not sharing much if anything with the existing code).
