* i386: Compile rtld-*.os with -mno-sse -mno-mmx -mfpmath=387H.J. Lu2016-07-181-2/+5
| | | | | | | | | | | | | Compile i386 rtld-*.os with -mno-sse -mno-mmx -mfpmath=387 so that no code in ld.so uses mm/xmm/ymm/zmm registers on i386 since the first 3 mm/xmm/ymm/zmm registers are used to pass vector parameters which must be preserved. * sysdeps/i386/Makefile (rtld-CFLAGS): New. [subdir == elf] (CFLAGS-.os): Replace -mno-sse -mno-mmx -mfpmath=387 with $(rtld-CFLAGS). [subdir != elf] (CFLAGS-.os): Compile rtld-*.os with $(rtld-CFLAGS).

* Avoid "inexact" exceptions in i386/x86_64 trunc functions (bug 15479).Joseph Myers2016-06-273-18/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed in <https://sourceware.org/ml/libc-alpha/2016-05/msg00577.html>, TS 18661-1 disallows ceil, floor, round and trunc functions from raising the "inexact" exception, in accordance with general IEEE 754 semantics for when that exception is raised. Fixing this for x87 floating point is more complicated than for the other versions of these functions, because they use the frndint instruction that raises "inexact" and this can only be avoided by saving and restoring the whole floating-point environment. As I noted in <https://sourceware.org/ml/libc-alpha/2016-06/msg00128.html>, I have now implemented a GCC option -fno-fp-int-builtin-inexact for GCC 7, such that GCC will inline these functions on x86, without caring about "inexact", when the default -ffp-int-builtin-inexact is in effect. This allows users to get optimized code depending on the options they pass to the compiler, while making the out-of-line functions follow TS 18661-1 semantics and avoid "inexact". This patch duly fixes the out-of-line trunc function implementations to avoid "inexact", in the same way as the nearbyint implementations. I do not know how the performance of implementations such as these based on saving the environment and changing the rounding mode temporarily compares to that of the C versions or SSE 4.1 versions (of course, for 32-bit x86 SSE implementations still need to get the return value in an x87 register); it's entirely possible other implementations could be faster in some cases.

* Fix i386/x86_64 scalbl with sNaN input (bug 20296).Joseph Myers2016-06-231-13/+3
| | | | | | | | | | | | | | | | | The x86_64 and i386 versions of scalbl return sNaN for some cases of sNaN input and are missing "invalid" exceptions for other cases. This results from overly complicated code that either returns a NaN input, or discards both inputs when one is NaN and loads a NaN from memory. This patch fixes this by simplifying the code to add the arguments when either one is NaN. Tested for x86_64 and x86. [BZ #20296] * sysdeps/i386/fpu/e_scalbl.S (__ieee754_scalbl): Add arguments when either argument is a NaN. * sysdeps/x86_64/fpu/e_scalbl.S (__ieee754_scalbl): Likewise. * math/libm-test.inc (scalb_test_data): Add sNaN tests.
* Simplify x86 nearbyint functions.Joseph Myers2016-06-223-12/+0
| | | | | | | | | | | | | | | | | | | | The i386 implementations of nearbyint functions, and x86_64 nearbyintl, contain code to mask the "inexact" exception. However, the fnstenv instruction has the effect of masking all exceptions, so this masking code has been redundant since fnstenv was added to those implementations (by commit 846d9a4a3acdb4939ca7bf6aed48f9f6f26911be; commit 71d1b0166b4ace0d804af2993b3815758b852efc added the test math/test-nearbyint-except-2.c that verifies these functions do work when called with "inexact" traps enabled); this patch removes the redundant code.

* Fix i386 fdim double rounding (bug 20255).Joseph Myers2016-06-141-0/+50
| | | | | | | | | | | | | | | | | | | fdim suffers from double rounding on i386 because subtracting two double values can produce an inexact long double value exactly half way between two double values. This patch fixes this by creating an i386-specific version of fdim - C, based on the generic version, unlike the previous .S version - which sets the x87 precision control to double precision for the subtraction and then restores it afterwards. As noted in the comment added, there are no issues of double rounding for subnormals (a case that setting precision control does not address) because subtraction cannot produce an inexact result in the subnormal range. Tested for x86_64 and x86. [BZ #20255] * sysdeps/i386/fpu/s_fdim.c: New file. Based on math/s_fdim.c. * math/libm-test.inc (fdim_test_data): Add another test.
* Use generic fdim on more architectures (bug 6796, bug 20255, bug 20256).Joseph Myers2016-06-146-282/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some architectures have their own versions of fdim functions, which are missing errno setting (bug 6796) and may also return sNaN instead of qNaN for sNaN input, in the case of the x86 / x86_64 long double versions (bug 20256). These versions are not actually doing anything that a compiler couldn't generate, just straightforward comparisons / arithmetic (and, in the x86 / x86_64 case, testing for NaNs with fxam, which isn't actually needed once you use an unordered comparison and let the NaNs pass through the same subtraction as non-NaN inputs). This patch removes the x86 / x86_64 / powerpc versions, so that those architectures use the generic C versions, which correctly handle setting errno and deal properly with sNaN inputs. This seems better than dealing with setting errno in lots of .S versions. The i386 versions also return results with excess range and precision, which is not appropriate for a function exactly defined by reference to IEEE operations. For errno setting to work correctly on overflow, it's necessary to remove excess range with math_narrow_eval, which this patch duly does in the float and double versions so that the tests can reliably pass on x86. For float, this avoids any double rounding issues as the long double precision is more than twice that of float. For double, double rounding issues will need to be addressed separately, so this patch does not fully fix bug 20255. Tested for x86_64, x86 and powerpc.

* Improve generic strcspn performanceWilco Dijkstra2016-04-011-18/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve strcspn performance using a much faster algorithm. It is kept simple so it works well on most targets. It is generally at least 10 times faster than the existing implementation on bench-strcspn on a few AArch64 implementations, and for some tests 100 times as fast (repeatedly calling strchr on a small string is extremely slow...). In fact the string/bits/string2.h inlines make no longer sense, as GCC already uses strlen if reject is an empty string, strchrnul is 5 times as fast as __strcspn_c1, while __strcspn_c2 and __strcspn_c3 are slower than the strcspn main loop for large strings (though reject length 2-4 could be special cased in the future to gain even more performance).

* Fix x86_64 / x86 powl inaccuracy for integer exponents (bug 19848).Joseph Myers2016-03-242-9/+9
| | | | | | | | | | | | | | | | | | | | | | | Bug 19848 reports cases where powl on x86 / x86_64 has error accumulation, for small integer exponents, larger than permitted by glibc's accuracy goals, at least in some rounding modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Various math_private.h headers are guarded by "#ifndef _MATH_PRIVATE_H", but never define the macro. Nothing else defines the macro either (the generic math_private.h that they include defines a different macro, _MATH_PRIVATE_H_), so those guards are ineffective. With the recent inclusion of s_sin.c in s_sincos.c, this breaks the build for MIPS, since the build of s_sincos.c ends up including <math_private.h> twice and the MIPS version defines inline functions such as libc_feholdexcept_mips, without a separate fenv_private.h header with its own guards such as some architectures have. This patch fixes all the problem headers to use architecture-specific guard macro names, and to define those macros in the headers they guard, just as some architectures already do.

* Handle more state in i386/x86_64 fesetenv (bug 16068).Joseph Myers2015-10-281-10/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fenv_t should include architecture-specific floating-point modes and status flags. i386 and x86_64 fesetenv limit which bits they use from the x87 status and control words, when using saved state, and limit which parts of the state they set to fixed values, when using FE_DFL_ENV / FE_NOMASK_ENV. The following should be included but are excluded in at least some cases: status and masking for the "denormal operand" exception (which isn't part of FE_ALL_EXCEPT); precision control (explicitly mentioned in Annex F as something that counts as part of the floating-point environment); MXCSR FZ and DAZ bits (for FE_DFL_ENV and FE_NOMASK_ENV). This patch arranges for this extra state to be handled by fesetenv (and thereby by feupdateenv, which calls fesetenv). (Note that glibc functions using floating point are not generally expected to work correctly with non-default values of this state, especially precision control, but it is still logically part of the floating-point environment and should be handled as such by fesetenv. Changes to the state relating to subnormals ought generally to work with libm functions when the arguments aren't subnormal and neither are the expected results; that's a consequence of functions avoiding spurious internal underflows.) A question arising from this is whether FE_NOMASK_ENV should or should not mask the "denormal operand" exception. I decided it should mask that exception. This is the status quo - previously that exception could only be unmasked by direct manipulation of control registers (possibly via <fpu_control.h>). In addition, it means that use of FE_NOMASK_ENV leaves a floating-point environment the same as could be obtained by fesetenv (FE_DFL_ENV); feenableexcept (FE_ALL_EXCEPT);, rather than an environment in which an exception is unmasked that could only be masked again by using fesetenv with FE_DFL_ENV (or a previously saved environment) - this exception not being usable with other <fenv.h> functions because it's outside FE_ALL_EXCEPT. Tested for x86_64 and x86. [BZ #16068] * sysdeps/i386/fpu/fesetenv.c: Include <fpu_control.h>. (FE_ALL_EXCEPT_X86): New macro.

* Fix i386 / x86_64 nearbyint exception clearing (bug 15491).Joseph Myers2015-10-223-42/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The implementations of nearbyint functions using x87 floating point (i386 all versions, x86_64 long double only) use the fclex instruction, which clears any exceptions that were raised before the function was called. These functions must not clear exceptions that were raised before they were called. This patch fixes these functions to save and restore the whole floating-point environment (fnstenv / fldenv) as the way of avoiding raising "inexact" (recall that there isn't an x87 instruction for loading just the status word, so the whole environment has to be saved and loaded instead - the code already saved and loaded the control word, which is now obtained from the saved environment after this patch, to disable traps on "inexact"). In the case of the long double functions, any "invalid" exception from frndint (applied to a signaling NaN) needs merging into the saved state; this issue doesn't apply to the float and double functions because that exception would have been raised when the argument is loaded, before the environment is saved.
