| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many m68k libm functions use their own system to share code between different types and functions, involving defining macros before including code for another function (for example, s_atan.c also acts as a template that can define other functions). Thes files serving as templates generate function aliases directly with e.g. "weak_alias (__CONCATX(__,FUNC), FUNC)" in s_atan.c. To be prepared to generate _Float32, _Float64 and _Float32x function aliases, this needs changing so that the libm_alias_* macros get used instead. As the macro to use varies depending on the type, that would mean additional macros to define in several different places to get the appropriate alias-generation macro used in each case. Rather than adding to the m68k-specific mechanisms, this patch converts the functions in question to use something closer to the math/ type-generic template mechanism. After this patch, these functions have m68k-specific templates such as s_atan_template.c, but those templates use all the same macros as in the math/ templates, such as FLOAT, M_DECL_FUNC, M_SUF and declare_mgen_alias. There is no automatic generation of the files such as s_atan.c that include the appropriate math-type-macros-*.h header and the template file (the existing automatic generation logic is only applicable for the fixed set of templates listed in math/ - and sysdeps sources always override files generated that way), so those files are still checked in, but they are all the obvious two-line files (with one additional definition in the case of the expm1 implementations), rather than making e.g. s_atan.c special. Functions are only converted where they should have aliases for _FloatN / _FloatNx types. Those m68k functions that do not generate public names (those that only generate __ieee754_*, with wrappers generating the public names, and classification functions that only exist once per format not once per type so don't get aliases) are unchanged. However, log1p (public names generated by wrapper) and significand (not provided for new types so no new aliases needed) needed changing because they previously included the atan implementations. Now, s_significand.c is the main implementation for functions with that prototype and using the old implementation approach, while log1p includes it in place of atan. Any further cleanups in this area (which preserve the proper set of functions getting aliases defined by libm_alias_float and libm_alias_double) are of course welcome, just not needed for the goals of this patch.

* Use libm_alias macros in m68k llrint functions.Joseph Myers2017-11-303-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most m68k libm functions share code via sources for one function including those for another function or type, in a way that will require significant changes to create function aliases in a way friendly to adding _FloatN / _FloatNx aliases. The llrint function implementations, however, use a conventional separate implementation for each floating-point type. Thus preparing them for _FloatN / _FloatNx aliases is just a matter of changing them to include the appropriate headers and use the appropriate macros, which this patch does. The llrintl changes aren't strictly required, since m68k long double does not meet the criteria for a _FloatN / _FloatNx type, but are included anyway to keep consistency between the implementations for the three types.

* x86: Make a space in jmpbuf for shadow stack pointerH.J. Lu2017-11-305-0/+156
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support Shadow Stack (SHSTK) in Intel Control-flow Enforcement Technology (CET) in setjmp/longjmp, we need to save shadow stack pointer in jmp_buf. The __saved_mask field in jmp_buf has type of __sigset_t. On Linux, __sigset_t is defined as #define _SIGSET_NWORDS (1024 / (8 * sizeof (unsigned long int))) typedef struct { unsigned long int __val[_SIGSET_NWORDS]; } __sigset_t; which is much bigger than expected by the __sigprocmask system call, which has typedef struct { unsigned long sig[_NSIG_WORDS]; } sigset_t; For Linux/x86, we can shrink __sigset_t used by __saved_mask in jmp_buf to add paddings for shadow stack pointer. As long as the new __sigset_t is not smaller than sigset_t expected by the __sigprocmask system call, it should work correctly. This patch adds an internal header file, <setjmpP.h>, to define __jmp_buf_sigset_t for __saved_mask in jmp_buf for Linux/x86 with a space to store shadow stack pointer. It verifies __jmp_buf_sigset_t has the suitable size for the __sigprocmask system call. A run-time test, tst-saved_mask-1.c, is added to verify that size of __jmp_buf_sigset_t is sufficient.

* Remove SPARC lllrint aliases.Joseph Myers2017-11-302-6/+0
| | | | | | | | | | | | | | | | | | | The sparc32/sparcv9/fpu/multiarch implementations of llrint / llrintf have aliases lllrint / lllrintf. No such function is exported from or used in libm and these aliases should not be there; I expect they arose accidentally in the course of converting a 64-bit implementation (where lrint and llrint can be aliases) to a 32-bit llrint implementation. This patch removes those spurious aliases. Tested (compilation only) with build-many-glibcs.py for sparcv9-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_llrint.S (__lllrint): Remove alias.

* Fix missing sparcv9 --disable-multi-arch fabsl compat symbol (bug 22229).Joseph Myers2017-11-291-0/+4
| | | | | | | | | | | | | | | | | | The --disable-multi-arch case of sparcv9 libm is missing a fabsl compat symbol for when long double had the same ABI as double. This patch adds the missing compat symbol to this implementation. As my fix for other instances of this missing compat symbol postdates the last release, I'm considering this as being part of bug 22229 that was missing from my previous fix rather than as a separate issue, and so as not needing a new bug report in Bugzilla. Tested (compilation only) with build-many-glibcs.py for sparcv9-linux-gnu --disable-multi-arch. [BZ #22229] * sysdeps/sparc/sparc32/sparcv9/fpu/s_fabs.S: Include <math_ldbl_opt.h>. (fabsl): Define as compat symbol at version GLIBC_2_0 for libm.

* Add _Float64x function aliases.Joseph Myers2017-11-2736-8/+1381
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues filling out TS 18661-3 support by adding *f64x function aliases on platforms with _Float64x support. (It so happens the set of such platforms is exactly the same as the set of platforms with _Float128 support, although on x86_64, x86 and ia32 the _Float64x format is Intel extended rather than binary128.) The API provided corresponds exactly to that provided for _Float128, mostly coming from TS 18661-3. As these functions always alias those for another type (long double, _Float128 or both), __* function names are not provided, as in other cases of alias types. Given the preparation done in previous patches, this one just enables the feature via Makeconfig and bits/floatn.h, adds symbol versions, and updates documentation and ABI baselines. The symbol versions are present unconditionally as GLIBC_2.27 in the relevant Versions files, as it's OK for those to specify versions for functions that may not be present in some configurations; no additional complexity is needed unless in future some configuration gains support for this type that didn't have such support in 2.27. The Makeconfig additions for ia64 and x86 aren't strictly needed, as those configurations also get float64x-alias-fcts definitions from sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given that _Float64x is not _Float128 for those configurations. A libm-test-ulps update for x86 is included. This is because bits/mathinline.h does not have _Float64x support added and for two functions the use of out-of-line functions results in increased ulps (ifloat64x shares ulps with ildouble / ifloat128 as appropriate). Given that we'd like generally to eliminate bits/mathinline.h optimizations, preferring to have such optimizations in GCC instead, it seems reasonable not to add such support there for new types. GCC support for _FloatN / _FloatNx built-in functions is limited, but has been improved in GCC 8, and at some point I hope the full set of libm built-in functions in GCC, and other optimizations with per-floating-type aspects, will be enabled for all _FloatN / _FloatNx types.
