manual: Avoid name collision in libm ULP table [BZ #28956]
The 32-bit and 64-bit variants of RISC-V share the same name - "RISC-V" - when generating the libm error table for the info pages. This collision, and the way how the table is generated, mean that the values in the final table for "RISC-V" may be either for the 32- or 64-bit variant, with no indication as to which. As an additional side-effect, this makes the build non-reproducible, as the error table generated is dependent upon the host filesystem implementation. To solve this issue, the libm-test-ulps-name files for both variants have been modified to include their word size, so as to remove the collision and provide more accurate information in the table. An alternative proposed was to merge the two variants' ULP values into a single file, but this would mean that information about error values is lost, as the two variants are not identical. Some differences are considerable, notably the values for the exp() function are large. Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com> |

Update copyright dates with scripts/update-copyrights
I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah.

math: Remove inline math tests
With mathinline removal there is no need to keep building and testing
inline math tests.
The gen-libm-tests.py support to generate ULP_I_* is removed and all
libm-test-ulps files are updated to longer have the
i{float,double,ldouble} entries. The support for no-test-inline is
also removed from both gen-auto-libm-tests and the
auto-libm-test-out-* were regenerated.
Checked on x86_64-linux-gnu and i686-linux-gnu.

RISC-V: Update LP64D libm-test-ulps.
With this patch applied, I get 13 glibc testsuite failures using TIMEOUTFACTOR=4 on a HiFive Unleashed running Fedora Core 29, using top of tree binutils and gcc. 5 of those failures are due to a kernel bug. Without the patch, there are over a hundred failures. This patch is incidentally similar to the powerpc-nofpu ulps update that Joseph Myers added a few days ago. * sysdeps/riscv/rv64/rvd/libm-test-ulps: Update. |

Remove unnecessary math_private.h includes.
After my changes to move various macros, inlines and other content from math_private.h to more specific headers, many files including math_private.h no longer need to do so. Furthermore, since the optimized inlines of various functions have been moved to include/fenv.h or replaced by use of function names GCC inlines automatically, a missing math_private.h include where one is appropriate will reliably cause a build failure rather than possibly causing code to be less well optimized while still building successfully. Thus, this patch removes includes of math_private.h that are now unnecessary. In the case of two RISC-V files, the include is replaced by one of stdbool.h because the files in question were relying on math_private.h to get a definition of bool. Tested for x86_64 and x86, and with build-many-glibcs.py. * math/fromfp.h: Do not include <math_private.h>. * math/s_cacosh_template.c: Likewise. * math/s_casin_template.c: Likewise. * math/s_casinh_template.c: Likewise. * math/s_ccos_template.c: Likewise. * math/s_cproj_template.c: Likewise. * math/s_fdim_template.c: Likewise. * math/s_fmaxmag_template.c: Likewise. * math/s_fminmag_template.c: Likewise. * math/s_iseqsig_template.c: Likewise. * math/s_ldexp_template.c: Likewise. * math/s_nextdown_template.c: Likewise. * math/w_log1p_template.c: Likewise. * math/w_scalbln_template.c: Likewise. * sysdeps/aarch64/fpu/feholdexcpt.c: Likewise. * sysdeps/aarch64/fpu/fesetround.c: Likewise. * sysdeps/aarch64/fpu/fgetexcptflg.c: Likewise. * sysdeps/aarch64/fpu/ftestexcept.c: Likewise. * sysdeps/aarch64/fpu/s_llrint.c: Likewise. * sysdeps/aarch64/fpu/s_llrintf.c: Likewise. * sysdeps/aarch64/fpu/s_lrint.c: Likewise. * sysdeps/aarch64/fpu/s_lrintf.c: Likewise. * sysdeps/i386/fpu/s_atanl.c: Likewise. * sysdeps/i386/fpu/s_f32xaddf64.c: Likewise. * sysdeps/i386/fpu/s_f32xsubf64.c: Likewise. * sysdeps/i386/fpu/s_fdim.c: Likewise. * sysdeps/i386/fpu/s_logbl.c: Likewise. * sysdeps/i386/fpu/s_rintl.c: Likewise. * sysdeps/i386/fpu/s_significandl.c: Likewise. * sysdeps/ia64/fpu/s_matherrf.c: Likewise. * sysdeps/ia64/fpu/s_matherrl.c: Likewise. * sysdeps/ieee754/dbl-64/s_atan.c: Likewise. * sysdeps/ieee754/dbl-64/s_cbrt.c: Likewise. * sysdeps/ieee754/dbl-64/s_fma.c: Likewise. * sysdeps/ieee754/dbl-64/s_fmaf.c: Likewise. * sysdeps/ieee754/flt-32/s_cbrtf.c: Likewise. * sysdeps/ieee754/k_standardf.c: Likewise. * sysdeps/ieee754/k_standardl.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_copysignl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_finitel.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_fpclassifyl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_isinfl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_isnanl.c: Likewise. * sysdeps/ieee754/ldbl-64-128/s_signbitl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_cbrtl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fma.c: Likewise. * sysdeps/ieee754/ldbl-96/s_fmal.c: Likewise. * sysdeps/ieee754/s_signgam.c: Likewise. * sysdeps/powerpc/power5+/fpu/s_modf.c: Likewise. * sysdeps/powerpc/power5+/fpu/s_modff.c: Likewise. * sysdeps/powerpc/power7/fpu/s_logbf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_ceil.c: Likewise. * sysdeps/riscv/rv64/rvd/s_floor.c: Likewise. * sysdeps/riscv/rv64/rvd/s_nearbyint.c: Likewise. * sysdeps/riscv/rv64/rvd/s_round.c: Likewise. * sysdeps/riscv/rv64/rvd/s_roundeven.c: Likewise. * sysdeps/riscv/rv64/rvd/s_trunc.c: Likewise. * sysdeps/riscv/rvd/s_finite.c: Likewise. * sysdeps/riscv/rvd/s_fmax.c: Likewise. * sysdeps/riscv/rvd/s_fmin.c: Likewise. * sysdeps/riscv/rvd/s_fpclassify.c: Likewise. * sysdeps/riscv/rvd/s_isinf.c: Likewise. * sysdeps/riscv/rvd/s_isnan.c: Likewise. * sysdeps/riscv/rvd/s_issignaling.c: Likewise. * sysdeps/riscv/rvf/fegetround.c: Likewise. * sysdeps/riscv/rvf/feholdexcpt.c: Likewise. * sysdeps/riscv/rvf/fesetenv.c: Likewise. * sysdeps/riscv/rvf/fesetround.c: Likewise. * sysdeps/riscv/rvf/feupdateenv.c: Likewise. * sysdeps/riscv/rvf/fgetexcptflg.c: Likewise. * sysdeps/riscv/rvf/ftestexcept.c: Likewise. * sysdeps/riscv/rvf/s_ceilf.c: Likewise. * sysdeps/riscv/rvf/s_finitef.c: Likewise. * sysdeps/riscv/rvf/s_floorf.c: Likewise. * sysdeps/riscv/rvf/s_fmaxf.c: Likewise. * sysdeps/riscv/rvf/s_fminf.c: Likewise. * sysdeps/riscv/rvf/s_fpclassifyf.c: Likewise. * sysdeps/riscv/rvf/s_isinff.c: Likewise. * sysdeps/riscv/rvf/s_isnanf.c: Likewise. * sysdeps/riscv/rvf/s_issignalingf.c: Likewise. * sysdeps/riscv/rvf/s_nearbyintf.c: Likewise. * sysdeps/riscv/rvf/s_roundevenf.c: Likewise. * sysdeps/riscv/rvf/s_roundf.c: Likewise. * sysdeps/riscv/rvf/s_truncf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_rint.c: Include <stdbool.h> instead of <math_private.h>. * sysdeps/riscv/rvf/s_rintf.c: Likewise. |

Use round functions not __round functions in glibc libm.
Continuing the move to use, within libm, public names for libm functions that can be inlined as built-in functions on many architectures, this patch moves calls to __round functions to call the corresponding round names instead, with asm redirection to __round when the calls are not inlined. An additional complication arises in sysdeps/ieee754/ldbl-128ibm/e_expl.c, where a call to roundl, with the result converted to int, gets converted by the compiler to call lroundl in the case of 32-bit long, so resulting in localplt test failures. It's logically correct to let the compiler make such an optimization; an appropriate asm redirection of lroundl to __lroundl is thus added to that file (it's not needed anywhere else). Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (round): Redirect using MATH_REDIRECT. * sysdeps/aarch64/fpu/s_round.c: Define NO_MATH_REDIRECT before header inclusion. * sysdeps/aarch64/fpu/s_roundf.c: Likewise. * sysdeps/ieee754/dbl-64/s_round.c: Likewise. * sysdeps/ieee754/dbl-64/wordsize-64/s_round.c: Likewise. * sysdeps/ieee754/float128/s_roundf128.c: Likewise. * sysdeps/ieee754/flt-32/s_roundf.c: Likewise. * sysdeps/ieee754/ldbl-128/s_roundl.c: Likewise. * sysdeps/ieee754/ldbl-96/s_roundl.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_round.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_roundf.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_round.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_roundf.c: Likewise. * sysdeps/riscv/rv64/rvd/s_round.c: Likewise. * sysdeps/riscv/rvf/s_roundf.c: Likewise. * sysdeps/ieee754/ldbl-128ibm/s_roundl.c: Likewise.

Use floor functions not __floor functions in glibc libm.
Similar to the changes that were made to call sqrt functions directly in glibc, instead of __ieee754_sqrt variants, so that the compiler could inline them automatically without needing special inline definitions in lots of math_private.h headers, this patch makes libm code call floor functions directly instead of __floor variants, removing the inlines / macros for x86_64 (SSE4.1) and powerpc (POWER5). The redirection used to ensure that __ieee754_sqrt does still get called when the compiler doesn't inline a built-in function expansion is refactored so it can be applied to other functions; the refactoring is arranged so it's not limited to unary functions either (it would be reasonable to use this mechanism for copysign - removing the inline in math_private_calls.h but also eliminating unnecessary local PLT entry use in the cases (powerpc soft-float and e500v1, for IBM long double) where copysign calls don't get inlined). The point of this change is that more architectures can get floor calls inlined where they weren't previously (AArch64, for example), without needing special inline definitions in their math_private.h, and existing such definitions in math_private.h headers can be removed. Note that it's possible that in some cases an inline may be used where an IFUNC call was previously used - this is the case on x86_64, for example. I think the direct calls to floor are still appropriate; if there's any significant performance cost from inline SSE2 floor instead of an IFUNC call ending up with SSE4.1 floor, that indicates that either the function should be doing something else that's faster than using floor at all, or it should itself have IFUNC variants, or that the compiler choice of inlining for generic tuning should change to allow for the possibility that, by not inlining, an SSE4.1 IFUNC might be called at runtime - but not that glibc should avoid calling floor internally. (After all, all the same considerations would apply to any user program calling floor, where it might either be inlined or left as an out-of-line call allowing for a possible IFUNC.) Tested for x86_64, and with build-many-glibcs.py. * include/math.h [!_ISOMAC && !(__FINITE_MATH_ONLY__ && __FINITE_MATH_ONLY__ > 0) && !NO_MATH_REDIRECT] (MATH_REDIRECT): New macro.

Do not include fenv_private.h in math_private.h.
Continuing the clean-up related to the catch-all math_private.h header, this patch stops math_private.h from including fenv_private.h. Instead, fenv_private.h is included directly from those users of math_private.h that also used interfaces from fenv_private.h. No attempt is made to remove unused includes of math_private.h, but that is a natural followup. (However, since math_private.h sometimes defines optimized versions of math.h interfaces or __* variants thereof, as well as defining its own interfaces, I think it might make sense to get all those optimized versions included from include/math.h, not requiring a separate header at all, before eliminating unused math_private.h includes - that avoids a file quietly becoming less-optimized if someone adds a call to one of those interfaces without restoring a math_private.h include to that file.) There is still a pitfall that if code uses plain fe* and __fe* interfaces, but only includes fenv.h and not fenv_private.h or (before this patch) math_private.h, it will compile on platforms with exceptions and rounding modes but not get the optimized versions (and possibly not compile) on platforms without exception and rounding mode support, so making it easy to break the build for such platforms accidentally. I think it would be most natural to move the inlines / macros for fe* and __fe* in the case of no exceptions and rounding modes into include/fenv.h, so that all code including fenv.h with _ISOMAC not defined automatically gets them. Then fenv_private.h would be purely the header for the libc_fe*, SET_RESTORE_ROUND etc. internal interfaces and the risk of breaking the build on other platforms than the one you tested on because of a missing fenv_private.h include would be much reduced (and there would be some unused fenv_private.h includes to remove along with unused math_private.h includes). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/generic/math_private.h: Do not include <fenv_private.h>.

RISC-V: Build Infastructure
This patch lays out the top-level orginazition of the RISC-V port. It
contains all the Implies files as well as various other fragments of
build infastructure for the RISC-V port. This contains the only change
to a shared file: config.h.in.
RISC-V is a family of base ISAs with optional extensions. The base ISAs
are RV32I and RV64I, which are 32-bit and 64-bit integer-only ISAs, but
this port currently only supports RV64I based systems. Support for
RISC-V lives in in sysdeps/riscv. In addition to these ISAs, our glibc
port supports most of the currently-defined extensions: the A extension
for atomics, the M extension for multiplication, the C extension for
compressed instructions, and the F/D extensions for single/double
precision IEEE floating-point. Most of these extensions are handled by
GCC, but glibc defines various floating-point wrappers and emulation
routines as well as some atomic wrappers.
We support running glibc-based programs on Linux, the support for which
lives in sysdeps/unix/sysv/linux/riscv.

RISC-V: Hard Float Support
This patch contains hardware floating-point support for the RISC-V ISA.
While we currently only support hard-float systems with both the F and D
extensions, I've left the F-specific code split out into seperate
folders in order to ease adding support for F-only and RV32I-based
systems in the future. I gave this a quick once-over and believe I've
removed all the code that implements RV32IF, RV32IFD, and RV64IF
targets.
