* Revert "Use allocation granularity as the 'page_size' in /proc/<pid>/status ↵Corinna Vinschen2018-08-171-1/+1
| | | | | | | | | | | as well, for consistency with /proc/<pid>/statm" This reverts commit 8a32c24a7bdb0f3d80daa8f267cc63d15edcf771. Replacing page_size() with allocation_granularity() was incorrect. The values returned by get_mem_values() are # of pages of size page_size(). Multiplying with allocation_granularity() here results in values 16 times too big.

* Fix strtof ("-nan") returns positive NaNMasamichi Hosoda2018-08-161-2/+2
| | | | | | | | | | | | strtof ("-nan") returned positive NaN instead of negative NaN. strtod ("-nan") and strtold ("-nan") return negative NaN. Linux glibc has been fixed that strto{f|d|ld} ("-nan") returns negative NaN. https://sourceware.org/bugzilla/show_bug.cgi?id=23007 This commit makes strtof preserves the negative sign bit when parsing "-nan" like glibc.
* Remove unused NaN's integer representation definitionsMasamichi Hosoda2018-08-166-93/+8
| | | | | | | | By previous commit, strto{d|ld} ("nan") does not use the definition of NaN. There is no other function that uses the definitions. This commit remove the definitions.
* Fix strtod ("nan") and strtold ("nan") returns wrong negative NaNMasamichi Hosoda2018-08-162-9/+2
| | | | | | | | | | | | | | The definition of qNaN for x86_64 and i386 was wrong. strto{d|ld} ("nan") returned wrong negative NaN instead of correct positive NaN since it used the wrong definition. On the other hand, strtof ("nan") returns correct positive NaN since it uses nanf ("") instead of the wrong definition. This commit makes strto{d|ld} ("nan") uses {nan|nanl} ("") like strtof ("nan") using. So strto{d|ld} ("nan") returns positive NaN.

* Keep the denormal-operand exception masked; modify FE_ALL_EXCEPT accordingly.J.H. van de Water2018-08-152-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By excluding the denormal-operand exception from FE_ALL_EXCEPT, it will not be possible anymore to UNmask this exception by means of the API defined by /usr/include/fenv.h Note: terminology has changed since IEEE Std 854-1987; denormalized numbers are called subnormal numbers nowadays. This modification has basically been motivated by the fact that it is also not possible on Linux to manipulate the denormal-operand exception by means of the interface as defined by /usr/include/fenv.h. This has been the state of affairs on Linux since 2001 (Andreas Jaeger). The exceptions required by the standard (IEEE Std 754), in case they can be supported by the implementation, are: FE_INEXACT, FE_UNDERFLOW, FE_OVERFLOW, FE_DIVBYZERO and FE_INVALID. Although it is allowed to define additional exceptions, there is no reason to support the "denormal-operand exception" in this case (fenv.h), because the subnormal numbers can be handled almost as fast the normalized numbers by the hardware of the x86/x86_64 architecture. Said differently, a reason to trap on the input of subnormal numbers does not exist. At least that is what William Kahan and others at Intel asserted around 2000. (that is William Kahan of the K-C-S draft, the precursor to the standard) This commit modifies winsup/cygwin/include/fenv.h as follows: - redefines FE_ALL_EXCEPT from 0x3f to 0x3d - removes the definition for FE_DENORMAL - introduces __FE_DENORM (0x2) (enum in Linux also uses __FE_DENORM) - introduces FE_ALL_EXCEPT_X86 (0x3f), i.e. ALL x86/x86_64 FP exceptions

* Cygwin: fegetenv() should not disable exceptionsJ.H. van de Water2018-08-031-1/+5
| | | | | | | | | | | | | | | fnstenv MUST be followed by fldenv in fegetenv(), as the former disables all exceptions in the x87 FPU, which is not appropriate here (fegetenv() ). fldenv after fnstenv should reload the x87 FPU w/ the configuration that was saved by fnstenv, i.e. a configuration that might have exceptions enabled. Note: x86_64 uses SSE for floating-point, not the x87 FPU. However, because feraiseexcept() attempts to provoke an exception using the x87 FPU, the bug in fegetenv() will make this attempt futile here (x86_64). Note: WoW uses the x87 FPU for floating-point, not SSE. Here anything that would normally result in triggering an exception, not only feraiseexcept(), will not be able to, as result of the bug in fegetenv().

* Define a new __alloc_size2 attribute to complement the exiting support.pfg2018-07-301-0/+2
| | | | | | | | | | | | | At least on GCC7 calling __alloc_size(x) twice is not equivalent to calling using the attribute once with two arguments. The later is the documented use in GCC documentation so add a new alloc_size(n, x) alternative to cover for the few places where it is used: basically: calloc(3), reallocarray(3) and mallocarray(9).

* sys: further adoption of SPDX licensing ID tags.pfg2018-07-301-0/+2
| | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.
* Make _Static_assert() work with GCC in older C++ standards.ed@FreeBSD.org2018-07-301-1/+1
| | | | | | | | | | | GCC only activates C11 keywords in C mode, not C++ mode. This means that when targeting an older C++ standard, we cannot fall back to using _Static_assert(). In this case, do define _Static_assert() as a macro that uses a typedef'ed array. Discussed in: r322875 commit thread Reported by: Mark MIllard MFC after: 1 month

* ctype: Fix integer type for caseconv_entry::deltaSebastian Huber2018-07-301-1/+1
| | | | | | | | | | | | | | | The commit 46ba1675c457324b0eeef4670a09101ef3f34c50 accidently changed a bit-field from signed to unsigned. The caseconv_entry::delta must be a signed integer, see also "newlib/libc/ctype/caseconv.t". Unfortunately, a standard GCC/Newlib build is done without -Wsign-conversion. Using this warning option would have helped to avoid this bug: caseconv.t:2:22: warning: unsigned conversion from 'int' to 'unsigned int:17' changes value from '-32' to '131040' [-Wsign-conversion] {0x0061, 25, TOUP, -32}, Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

* POSIX Asynchronous I/O support: other filesMark Geisert2018-07-2510-26/+44
| | | | | | Updates to misc files to integrate AIO into the Cygwin source tree. Much of it has to be done when adding any new syscalls. There are some updates to limits.h for AIO-specific limits. And some doc mods.
* POSIX Asynchronous I/O support: fhandler filesMark Geisert2018-07-254-34/+83
| | | | | | | | | | | This code is where the AIO implementation is wired into existing Cygwin mechanisms for file and device I/O: the fhandler* functions. It makes use of an existing internal routine prw_open to supply a "shadow fd" that permits asynchronous operations on a file the user app accesses via its own fd. This allows AIO to read or write at arbitrary locations within a file without disturbing the app's file pointer. (This was already the case with normal pread|pwrite; we're just adding "async" to the mix.)
* POSIX Asynchronous I/O support: aio filesMark Geisert2018-07-252-0/+1087
| | | | | | This is the core of the AIO implementation: aio.cc and aio.h. The latter is used within the Cygwin DLL by aio.cc and the fhandler* modules, as well as by user programs wanting the AIO functionality.
