* Fix multido compilation on ARMTamar Christina2017-10-091-2/+2
| | | | | | | | | | | | | The previous multi-build implementation was copying the config.status from the parent multilib directory when building the different semihosting variants. It did so because the configuration doesn't change. However when you use a relative path to configure it turns out that the paths inside the config.status are also relative. To fix this, the srcdir is adjusted from the initial configuration instead of copying it. Tested on aarch64-none-elf and arm-none-eabi. Signed-off-by: Tamar Christina <tamar.christina@arm.com>
* cygwin: initialize variable for stack unwindingMichael Haubenwallner2017-10-091-1/+1
| | | | | | | The third argument of RtlLookupFunctionEntry actually is documented as _Inout_opt_ for both x64 and ARM, although generic doc says _Out_ only. * exceptions.cc (__unwind_single_frame): Initialize hist variable.

* cygwin: workaround GCC 6 changesYaakov Selkowitz2017-09-123-2/+6
| | | | | | | | | | | | | GCC 6 includes a number of new warnings which cause Cygwin to either not compile, or not work properly even if said warnings are ignored: https://cygwin.com/ml/cygwin-developers/2017-09/msg00000.html https://gcc.gnu.org/gcc-6/porting_to.html For now, we use the flags necessary to revert to GCC 5 behaviour until we can fix the code properly.

* Change time_t to 64-bit by defaultSebastian Huber2017-09-077-3/+60
| | | | | | | | | In order to avoid the year 2038 problem, define time_t to a signed integer with at least 64-bits. The type for time_t can be forced to long with the --enable-newlib-long-time_t configure option or with the _USE_LONG_TIME_T system configuration define.

* Remove harmful casts in gmtime_r()Sebastian Huber2017-09-071-2/+2
| | | | | | | | In case time_t is long, then the cast to long is a nop. In case time_t is __int_least64_t, then the cast to long may truncate the value before the division. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Let RTEMS provide clock()Sebastian Huber2017-09-071-1/+1
| | | | | | | | | | | Newlib uses _times_r() in clock(). The problem is that the _times_r() clock frequency is defined by sysconf(_SC_CLK_TCK). The clock frequency of clock() is the constant CLOCKS_PER_SEC. FreeBSD uses getrusage() for clock(). Since RTEMS has only one process, the implementation can be simplified.

* Revert "headers: avoid bareword attributes" for clangEric Blake2017-08-251-14/+16
| | | | | | | | | | | | | | | This reverts most of commit 979d467ff6e39ee5c52cf1aac7a6c9c63058141c. We cannot avoid some bareword attributes until clang is fixed to properly support __-decorated attributes; see this bug: https://bugs.llvm.org/show_bug.cgi?id=34319 The macros in question expand to the empty string under gcc, so only compilation under clang is affected, and since clang has the bug, the obvious solution is to roll back the changes, and document the issue.
