2016-04-29erl_process: Restore R18 HiPE PCB offsetsMagnus Lång
It was recently observed that the LLVM backend for HiPE was broken, generating code that crashes the VM. It turns out that this was caused by LLVM hard-coding an offset into the Erlang PCB, which became incorrect as of commit 3ac08f9b, that introduced a new member into the PCB before the HiPE-specific state, changing its offsets. For now, until a proper fix is implemented, we move this new member to after the HiPE-specific state, allowing the LLVM backend to work once more.

2016-04-26matherr() must not fake an FP exceptionMikael Pettersson
When FP exceptions are used, matherr() forces a fake FP exception, which is interpreted as an error by the checking code after a math routine call. This is wrong for several reasons: - it's not necessary for error checking: when FP exceptions aren't used, matherr() is a stub and no information is derived from it being called - it's not necessary for FPU maintenance: the FPU only needs to be reprogrammed after an actual FP exception - it causes false negatives: matherr() may be called even though Erlang doesn't consider the case to be an error (exp() and pow() underflows on Solaris for instance); with FP exceptions enabled they are incorrectly considered errors The fix is to remove all FP exception related code from matherr().

2016-04-25Print heap pointers for garbing processes during crashdumpSimon Cornish
In an SMP emulator, print_garb_info doesn't do anything because the heap pointers could be invalid. However, when crashdumping there are no schedulers running so it's ok to print this additional information which could be useful when examining a core file.
