2014-12-02erts: Fix finite warning for clangLukas Larsson
clang aka llvm claims to be __GNUC__ and thus we have to explicitly check that it is not used.
2014-11-24erts: Use finite instead of isfinite with gccLukas Larsson
Turns out that isfinite emits a function call and not an instruction in gcc, this makes estone float arith about 50-75% slower. finite emits the instruction so we use that instead.

2014-10-29erts: Fix bug in beam_rangesSverker Eriksson
Symptom: VM on OSX (darwin11.4.2) with +Meamin running sasl tests, crashing when init:reboot() does erlang:purge_module(installer). Problem: Off-by-one bug in beam_ranges:find_range, returning the wrong range if the 'end' of one module is the 'start' of the next. This is only possible if using sys_alloc (+Meamin) as our own allocators always put block headers between allocated payload data.

2014-10-28Use isfinite() instead of finite() when availableAnthony Ramine
OS X Mavericks builds result in a number of warnings about finite() being deprecated, like these: beam/erl_arith.c:451:7: warning: 'finite' is deprecated: first deprecated in OS X 10.9 [-Wdeprecated-declarations] ERTS_FP_ERROR(p, f1.fd, goto badarith); ^ sys/unix/erl_unix_sys.h:319:33: note: expanded from macro 'ERTS_FP_ERROR' ^ sys/unix/erl_unix_sys.h:244:51: note: expanded from macro '__ERTS_FP_ERROR' ^ /usr/include/math.h:718:12: note: 'finite' has been explicitly marked deprecated here extern int finite(double) __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_0, __MAC_10_9, __IPHONE_NA, __IPHONE_NA); Add checks to use isfinite() instead of finite() where available. Verified on OS X Mavericks 10.9.5 and Ubuntu 12.04.

2014-10-21erts: Fix bug when hipe tailcalls trapping BIF that disables GCSverker Eriksson
Symptom: base64_SUITE:roundtrip crashes with hipe compiled stdlib. Problem: HIPE_WRAPPER_BIF_DISABLE_GC pushed a "trap frame", but the frame was only popped if the call was recursive. Solution: Only reserve "trap frame" if BIF call is recursive.
2014-10-21erts: Fix hipe bug when gc-disabling bif traps with gc enabledSverker Eriksson
The trap_frame got pushed twice, first by the wrapper then by hipe_push_beam_trap_frame as it was looking at F_DISABLE_GC.
2014-10-19Fix bug in FreeBSD topology detection codePaul Guyot
Code incorrectly relied on undefined C behavior. Clang and gcc 4.9 do not behave as code expected. This affected cores and processors detection on FreeBSD.
2014-10-17Clarify the use of SIGUSR1 for forcing crash dumpsSteve Vinoski
The crash_dump document mentions indirectly that delivering a SIGUSR1 to a running emulator process can force it to crash dump. Clarify that text to make it clear SIGUSR1 can be used for that purpose, and also add a similar note about using SIGUSR1 to the erl documentation.
2014-10-17Clarify docs for driver_async() return valueSteve Vinoski
The documentation for driver_async() still referred to the return value of the function as a "handle", which is no longer meaningful since driver_async_cancel() was deprecated and removed. Modify the documentation to simply indicate that the driver_async() return value will be -1 if it fails.

2014-10-03erts: Fix bug when delayed deallocated carrier is reused by cpool_fetchSverker Eriksson
The delayed dealloc queue destroyes one word but cpool_fetch() is expected to return healthy carriers. So we restore that overwritten word with a little bit of hackish code.
2014-10-02erts: Mend port_set_data with non-immed data for halfword VMSverker Eriksson
2014-10-02Fix missing field initializer in ERL_NIF_INIT macroSteve Vinoski
In the ERL_NIF_INIT macro, add a missing static initializer for the new options field which was added to the ErlNifEntry struct for 17.3. This fix prevents compile-time errors in NIFs when the compiler is instructed to treat missing field initializers as errors.

Always update prt->data with atomic xchg-op. Check for NULL data to detect racing port terminator. Use NULL, as THE_NON_VALUE can be a valid pointer on debug VM.

hsize field was not set leading to VM crash

2014-09-10erts: Correct dirty scheduler NIF API for WindowsSverker Eriksson
enif_schedule_nif() put LAST of the unconditional functions to keep the order which is vital for ABI compatibility on Windows. The conditional dirty scheduler stuff moved down at the end of the list to keep them out of the way. We don't want them mess things up then they become unconditional some day.
