* math.h: Use GCC builtins for C99 macros where availableCorinna Vinschen2016-03-261-19/+55
| | | | | | | | | | | | | | | | GCCs builtin functions are mostly type agnostic and architecture indepedent. Prefer to use them if available. * libc/include/math.h (fpclassify, isfinite, isinf, isnan, isnormal): Use matching GCC builtin functions if built with GCC 4.4 or later. (signbit): Use matching GCC builtin functions if built with GCC 4.0 or later. (isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered): Use matching GCC builtin functions if built with GCC 2.97 or later. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* finitel: Use correct GCC builtinCorinna Vinschen2016-03-261-1/+1
| | | | | | | | | | __builtin_isinf_sign doesn't reflect the correct return value for NaN to emulate finite function. Use __builtin_isfinite instead whichg is available since GCC 4.4 just as __builtin_isinf_sign. * libm/common/sl_finite.c (finitel): Use __builtin_isfinite.

* strtold: Fix Infinity value.Corinna Vinschen2016-03-261-1/+2
| | | | | | | | | | Infinity returned from strtold is recognized as NaN by GCC builtin functions. The reason is that ULtox is missing to set a bit. * libc/stdlib/strtorx.c (ULtox): Set high bit in second word to create valid Infinity value. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Initializing TTBR0 to inner/outer WBJiong Wang2016-03-261-1/+10
| | | | | | | | | | | | | | | | | | | | | While running tests on internal systems, we identified an issue in the startup code for newlib on AArch32 systems with Multiprocessor Extensions to the architecture. The issue is we were configuring page table flags to be Inner cacheable/Outer non-cacheable, while for at least architectures with Multiprocessor Extension, we'd configure it to Inner/Outer write-back, no write-allocate, and cacheable. The attached patch fixes this, and no regression on arm-none-eabi bare-metal tests. Adopted suggestion given by Richard offline to avoid using jump. libgloss/ * arm/cpu-init/rdimon-aem.S: Set TTBR0 to inner/outer cacheable WB, and no allocate on WB for arch with multiprocessor extension.

* Throughout Cygwin, use u_intN_t or uintN_tCorinna Vinschen2016-03-2416-82/+86
| | | | | | | | | | Don't use u_char, u_short, u_int or u_long in Cygwin, unless it refers to the Winsock types. Use u_intN_t in BSD-based sources, unsigned char where strings are concerned, uintN_t otherwise. Also: * net.cc: Fix comment, we're not using u_long anymore.

* Drop usage of old-age BSD types in generically used Cygwin headersCorinna Vinschen2016-03-247-49/+48
| | | | | | | | | | | | | | | | | | | | | | | | u_char, u_short, u_int, u_long are BSD-only types. Remove them from Cygwin headers which are supposed to be used in a non-BSD scenario. Drop special Cygwin handling of those types in sys/types.h. newlib: * libc/include/sys/types.h (u_char,u_short,u_int,u_long): Drop Cygwin exception. cygwin: * fhandler_socket.cc (fhandler_socket::ioctl): Accommodate change in include/asm/socket.h. Continue using u_long since that's the MS type here. * include/asm/socket.h: Since the type given in _IOR/_IOW macros is only used for its sizeof, replace u_long with equivalent long. * netdb.h (getnetbyaddr): Fix prototype. * netinet/ip.h: Replace old BSD-only types with generically defined old BSD types (u_char -> u_int8_t, etc). * netinet/tcp.h: Ditto. * netinet/udp.h: Ditto.

* Define BSD u_intN_t types indiscriminatelyCorinna Vinschen2016-03-242-34/+14
| | | | | | | | | | | | | | The u_intN_t types are BSD types but sanctioned by POSIX. They are always defined when using Glibc headers so we follow suit. newlib: * libc/include/sys/types.h: Drop outdated __INTTYPES_DEFINED__ macro. Always define u_intN_t types. cygwin: * include/cygwin/types.h: Remove definition of u_intN_t types. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Feature test macros overhaul: C++ TR1Yaakov Selkowitz2016-03-231-5/+5
| | | | | | | | | | | | While C++11 was the first version of the standard to use C99 functionality, TR1 (for C++03) also does, and G++ does not distinguish between C++98 and C++03, or when TR1 is in use. Therefore, while not strictly correct for "pure" C++98, enabling C99 for all C++ usage is the simplest solution (and much better than always using -D_GNU_SOURCE as on Linux).

* Only allow enabled groups as primary groupCorinna Vinschen2016-03-231-6/+45
| | | | | | | | | | | | So far any group in the user's token could be used as primary group. Windows doesn't check if the primary group is enabled or not, it just has no meaning. From a POSIXy point of view it can lead to weird results though. * uinfo.cc (check_token_membership): New static function. (internal_getlogin): Only allow enabled groups as primary group.

* Use 64K buffers for TOKEN_GROUPSCorinna Vinschen2016-03-231-3/+3
| | | | | | | | | | A user token can be up to 64K in size. Using 32K buffers for TOKEN_GROUPS may be insufficient. * uinfo.cc (get_logon_sid): Use 64K buffers for the TOKEN_GROUPS array. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Allocate temporary TOKEN_GROUP arrays using TLSCorinna Vinschen2016-03-231-28/+12
| | | | | | | | | | | | | A user token can be up to 64K in size. The group list might take a lot of that so use tmp_pathbuf allocated space rather than stack space allocted via alloca. In create_token the TOKEN_GROUP was allocated via malloc, but the code is needlessly complicated. Simplify by using tmp_pathbuf as well. * sec_auth.cc (verify_token): Allocate TOKEN_GROUP via tmp_pathbuf. (create_token): Ditto. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* cxx.cc: Disable C++14 warning for new sized delete operatorCorinna Vinschen2016-03-231-0/+4

| | | | | | | | | | When running RTEMS paravirtualized in user space, the cli/sti instructions can't be used. But I can't see why they are needed in either user or supervisor state. Turning the use of them off for RTEMS. This code is unmodified since the beginning of the repository, so I have no insight into why it was done. I may even have been the one to add them. Absolutely no idea except they aren't necessary.
