Refactor long double information into bits/long-double.h.
Information about whether the ABI of long double is the same as that of double is split between bits/mathdef.h and bits/wordsize.h. When the ABIs are the same, bits/mathdef.h defines __NO_LONG_DOUBLE_MATH. In addition, in the case where the same glibc binary supports both -mlong-double-64 and -mlong-double-128, bits/wordsize.h defines __LONG_DOUBLE_MATH_OPTIONAL, along with __NO_LONG_DOUBLE_MATH if this particular compilation is with -mlong-double-64. As part of the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, this patch puts all that information in a single header, bits/long-double.h. It is included from sys/cdefs.h alongside the include of bits/wordsize.h, so other headers generally do not need to include bits/long-double.h directly. Previously, various bits/mathdef.h headers and bits/wordsize.h headers had this long double information (including implicitly in some bits/mathdef.h headers through not having the defines present in the default version). After the patch, it's all in six bits/long-double.h headers. Furthermore, most of those new headers are not architecture-specific. Architectures with optional long double all use the ldbl-opt sysdeps directory, either in the order (ldbl-64-128, ldbl-opt, ldbl-128) or (ldbl-128ibm, ldbl-opt). Thus a generic header for the case where long double = double, and headers in ldbl-128, ldbl-96 and ldbl-opt, suffices to cover every architecture except for cases where long double properties vary between different ABIs sharing a set of installed headers; fortunately all the ldbl-opt cases share a single compiler-predefined macro __LONG_DOUBLE_128__ that can be used to tell whether this compilation is -mlong-double-64 or -mlong-double-128. The two cases where a set of headers is shared between ABIs with different long double properties, MIPS (o32 has long double = double, other ABIs use ldbl-128) and SPARC (32-bit has optional long double, 64-bit has required long double), need their own bits/long-double.h headers. As with bits/wordsize.h, multiple-include protection for this header is generally implicit through the include guards on sys/cdefs.h, and multiple inclusion is harmless in any case. There is one subtlety: the header must not define __LONG_DOUBLE_MATH_OPTIONAL if __NO_LONG_DOUBLE_MATH was defined before its inclusion, because doing so breaks how sysdeps/ieee754/ldbl-opt/nldbl-compat.h defines __NO_LONG_DOUBLE_MATH itself before including system headers. Subject to keeping that working, it would be reasonable to move these macros from defined/undefined #ifdef to always-defined 1/0 #if semantics, but this patch does not attempt to do so, just rearranges where the macros are defined. After this patch, the only use of bits/mathdef.h is the alpha one for modifying complex function ABIs for old GCC. Thus, all versions of the header other than the default and alpha versions are removed, as is the include from math.h. Tested for x86_64 and x86.

Fix arg used as litteral suffix in tst-strfrom.h
The macro ENTRY in tst-strfrom.h is used to generate the input values for each floating-point type (float, double, long double). It should append the parameter LSUF (Literal suffix) to the floating-point number, but is using CSUF (C function suffix). This patch fixes it. Tested for powerpc64le and x86_64. |

support: Introduce new subdirectory for test infrastructure
The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected. |

Ignore -Wmaybe-uninitialized in stdlib/bug-getcontext.c.
Doing all-ABIs compile testing produces a compiler warning in
stdlib/bug-getcontext.c on nios2 and tilepro (with GCC 5 branch):
bug-getcontext.c: In function 'do_test':
bug-getcontext.c:53:6: error: 'except_mask' may be used uninitialized in this function [-Werror=maybe-uninitialized]
if (mask != except_mask)
^
This warning appears nonsensical; except_mask is initialized where
it's declared. I think what must be happening here is that the
compiler is confused by the returns-twice nature of getcontext: if
there were a call to setcontext, local variables could indeed have
lost their values on the second return from getcontext. This patch
duly uses the DIAG_* macros to disable the warning here.
Tested for nios2 and tilepro (compilation only; after this patch all
the tests compile, though there are other failures) and x86_64 (full
testsuite run).
* stdlib/bug-getcontext.c: Include <libc-internal.h>.
(do_test): Disable -Wmaybe-uninitialized around uses of
except_mask.

Make strtod raise "inexact" exceptions (bug 19380).
The strtod function should raise the "inexact" exception when its result is inexact, but fails to do so except in the case of underflow or overflow. This patch fixes it to do so for all inexact results. tst-strtod-round is extended to test for this exception; the generator is fixed to properly mark inexact results as such in the case where the inexactness is from the mpfr_subnormalize step. Tested for x86_64, x86 and powerpc. [BZ #19380] * stdlib/strtod_l.c (round_and_return): Force "inexact" exception for inexact results. * stdlib/gen-tst-strtod-round.c (string_to_fp): Return indication of inexact result where mpfr_subnormalize is the only inexact step. * stdlib/tst-strtod-round-data.h: Regenerated. * stdlib/tst-strtod-round-skeleton.c [!FE_INEXACT] (FE_INEXACT): Define to 0. (GEN_ONE_TEST): Test inexact exceptions raised are as expected. |

Add <stdint.h> integer width macros.
TS 18661-1 defines macros for the width of integer types, intended for use with the fromfp functions to convert from floating-point types to integer types of any width, in any rounding mode and with control over whether "inexact" is raised.

Having previously added the <limits.h> macros, this patch adds the <stdint.h> ones.

libio: Implement vtable verification [BZ #20191]
This commit puts all libio vtables in a dedicated, read-only ELF section, so that they are consecutive in memory. Before any indirect jump, the vtable pointer is checked against the section boundaries, and the process is terminated if the vtable pointer does not fall into the special ELF section. To enable backwards compatibility, a special flag variable (_IO_accept_foreign_vtables), protected by the pointer guard, avoids process termination if libio stream object constructor functions have been called earlier. Such constructor functions are called by the GCC 2.95 libstdc++ library, and this mechanism ensures compatibility with old binaries. Existing callers inside glibc of these functions are adjusted to call the original functions, not the wrappers which enable vtable compatiblity. The compatibility mechanism is used to enable passing FILE * objects across a static dlopen boundary, too. |

quick_exit tests: Do not use C++ headers
If C++ headers such as <cstdlib> or <thread> are used, GCC 6 will include /usr/include/stdlib.h (instead of stdlib/stdlib.h in the glibc source directory), and this turns up as a make dependency. An implicit rule will kick in and make will try to install stdlib/stdlib.h as /usr/include/stdlib.h because the target is out of date. This commit switches to <stdlib.h> and <pthread.h> instead of <cstdlib> and <thread>. |

Bug 20198: quick_exit should not call destructors.
In C++11 18.5.12 says "Objects shall not be destroyed as a result of calling quick_exit." In C11 quick_exit is silent about thread object destruction. Therefore to make glibc C++ compliant we do not call any thread local destructors. A new regression test verifies the fix. I will note that C++11 18.5.3 makes it clear that C++ defines additional requirements for _Exit() to prevent it from executing destructors. Given that the point of _Exit() is to terminate the process immediately it makes sense the C and C++ should line up and avoid calling destructors. No failures. New regtest passes. |

Fix nan functions handling of payload strings (bug 16961, bug 16962).
The nan, nanf and nanl functions handle payload strings by doing e.g.:
if (tagp[0] != '\0')
{
char buf[6 + strlen (tagp)];
sprintf (buf, "NAN(%s)", tagp);
return strtod (buf, NULL);
}
This is an unbounded stack allocation based on the length of the
argument. Furthermore, if the argument starts with an n-char-sequence
followed by ')', that n-char-sequence is wrongly treated as
significant for determining the payload of the resulting NaN, when ISO
C says the call should be equivalent to strtod ("NAN", NULL), without
being affected by that initial n-char-sequence. This patch fixes both
those problems by using the __strtod_nan etc. functions recently
factored out of strtod etc. for that purpose, with those functions
being exported from libc at version GLIBC_PRIVATE.
Tested for x86_64, x86, mips64 and powerpc.

Refactor strtod parsing of NaN payloads.
The nan* functions handle their string argument by constructing a NAN(...) string on the stack as a VLA and passing it to strtod functions. This approach has problems discussed in bug 16961 and bug 16962: the stack usage is unbounded, and it gives incorrect results in certain cases where the argument is not a valid n-char-sequence. The natural fix for both issues is to refactor the NaN payload parsing out of strtod into a separate function that the nan* functions can call directly, so that no temporary string needs constructing on the stack at all. This patch does that refactoring in preparation for fixing those bugs (but without actually using the new functions from nan* - which will also require exporting them from libc at version GLIBC_PRIVATE). This patch is not intended to change any user-visible behavior, so no tests are added (fixes for the above bugs will of course add tests for them). This patch builds on my recent fixes for strtol and strtod issues in Turkish locales. Given those fixes, the parsing of NaN payloads is locale-independent; thus, the new functions do not need to take a locale_t argument.

Fix strtod ("NAN(I)") in Turkish locales (bug 19266).
The implementations of strtod and related functions use locale-specific conversions to lower case when parsing the contents of a string NAN(n-char-sequence_opt). This has the consequence that NAN(I) is not treated as being of that form (only the initial NAN part is accepted). The syntax of n-char-sequence directly maps to the ASCII letters, digits and underscore as in identifiers, so it is unambiguous that all ASCII letters must be accepted in all locales. This patch, relative to a tree with <https://sourceware.org/ml/libc-alpha/2015-11/msg00258.html> (pending review) applied and depending on that patch, fixes this problem by checking directly for ASCII letters. This will have the side effect of no longer accepting 'İ' (dotted 'I') inside NAN() in Turkish locales, which seems appropriate (that letter wouldn't have been interpreted as having any meaning in the NaN payload anyway, as not acceptable to strtoull). Tested for x86_64 and x86.

Fix strtol in Turkish locales (bug 19242).
The implementations of strtol and related functions use locale-specific conversions to upper case before determining whether a character is a valid letter in the argument. This means that in Turkish locales such as tr_TR.UTF-8 and tr_TR.ISO-8859-9, "i" is interpreted as not being a valid number, when if the base passed to strtol is 19 or more it should be interpreted as the number 18. ISO C explicitly says "The letters from a (or A) through z (or Z) are ascribed the values 10 through 35", so clearly intends the standard ASCII letters (otherwise you wouldn't generally have exactly 26 letters to ascribe such values) (whereas white-space must be identified according to the locale). In particular, 'i' and 'I' must be understood to be in that sequence. This patch makes the code do the case conversions and classification in the C locale; the user's locale remains used for whitespace testing (explicitly correct according to ISO C). Note that the way the code worked, the only non-ASCII letter that would previously have been accepted would have been the Turkish 'ı' (dotless 'i'), because the uppercase version of that in Turkish locales is 'I'. This patch means that will no longer be accepted, which seems appropriate. Tested for x86_64 and x86. [BZ #19242] * stdlib/strtol_l.c (ISALPHA): Use _nl_C_locobj_ptr for locale.

Remove GCC version conditionals on -Wmaybe-uninitialized pragmas.
One common case of __GNUC_PREREQ (4, 7) conditionals is use of diagnostic control pragmas for -Wmaybe-uninitialized, an option introduced in GCC 4.7 where older GCC needed -Wuninitialized to be controlled instead if the warning appeared with older GCC. This patch removes such conditionals. (There remain several older uses of -Wno-uninitialized in makefiles that still need to be converted to diagnostic control pragmas if the issue is still present with current sources and supported GCC versions, and it's likely that in most cases those pragmas also will end up controlling -Wmaybe-uninitialized.) Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch, except for libresolv since res_send.c contains assertions whose line numbers are changed by the patch). * resolv/res_send.c (send_vc) [__GNUC_PREREQ (4, 7)]: Make code unconditional. * soft-fp/fmadf4.c [__GNUC_PREREQ (4, 7)]: Likewise.

Convert miscellaneous function definitions to prototype style.
This patch converts various miscellaneous functions definitions in glibc, found with grep and not covered by my previous scripted conversions, from old-style K&R to prototype-style. These changes were made manually. This is not necessarily exhaustive as formatting variants may have prevented my grep from finding some such definitions. Regarding the changes to files from GMP, they may originally have been omitted when removing __STDC__ conditionals because of the files coming from another package, but (a) GMP no longer has __STDC__ conditionals there anyway and (b) we don't try to keep these files verbatim in sync with GMP (and there are licensing differences), so making the change to them in glibc seems reasonable.

Convert 113 more function definitions to prototype style (files with assertions).
This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.

Convert 69 more function definitions to prototype style (line wrap cases).
This automatically-generated patch converts 69 function definitions in glibc from old-style K&R to prototype-style. This patch, covering both sysdeps and non-sysdeps files, deals with cases where the prototype needed to be wrapped over more than one line. Otherwise, exclusions and caveats are as for <https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00599.html>.

Convert 703 function definitions to prototype style.
This automatically-generated patch converts 703 function definitions in glibc from old-style K&R to prototype-style. This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.

Refactor code forcing underflow exceptions.
Various floating-point functions have code to force underflow exceptions if a tiny result was computed in a way that might not have resulted in such exceptions even though the result is inexact. This typically uses math_force_eval to ensure that the underflowing expression is evaluated, but sometimes uses volatile. This patch refactors such code to use three new macros math_check_force_underflow, math_check_force_underflow_nonneg and math_check_force_underflow_complex (which in turn use math_force_eval). In the limited number of cases not suited to a simple conversion to these macros, existing uses of volatile are changed to use math_force_eval instead. The converted code does not always execute exactly the same sequence of operations as the original code, but the overall effects should be the same.

Use math_narrow_eval more consistently.
Where glibc code needs to avoid excess range and precision in floating-point arithmetic, code variously uses either asms or volatile to force the results of that arithmetic to memory; mostly this is conditional on FLT_EVAL_METHOD, but in the case of lrint / llrint functions some use of volatile is unconditional (and is present unnecessarily in versions for long double). This patch make such code use the recently-added math_narrow_eval macro consistently, removing the unnecessary uses of volatile in long double lrint / llrint implementations completely.
