2011-03-29Fix duplicate entries in stacktraces after calling certain BIFsBjörn Gustavsson
Calling a BIF thaf is called as a function (such as process_info/{1,2}) would leave a non-zero value in c_p->cp, which would lead to duplicate entries in the stacktrace.
2011-03-29BEAM loader: Simplify handling of the func_info/3 instructionBjörn Gustavsson
For some historical reason, the transformation of a func_info/3 instruction to the internal i_func_info/4 instruction is more involved than it needs to be. Remove the gen_func_info() function in the loader and use a simple transformation.

* sverker/valgrind-new-suppressions: Make halfword emulator with valgrind target allocate low memory Add erts_alloc_permanent_cache_aligned to supress valgrind
2011-03-09Fix 18 exabyte memory allocation failureBjörn Gustavsson
The new_binary() function takes a size argument that is an int. In the 64-bit emulator (sizeof(int) == 4, sizeof(Uint) == 8), any sizes >= 0x8000000 become 0xffffffff80000000 and above and triggers a memory allocation failure. Change the type of the size argument to Uint, and change any callers that cast the argument to an int. Correction-by: Jon Meredith

2011-03-04erts: Initialize register that may be referenced by garbage collectionBjörn Gustavsson
The call_fun() function in the BEAM emulator is supposed to to put the fun term in the x register following the actual arguments and environment for the fun. But if the fun is not loaded and a call to the error_handler:undefined_lambda/3 function is set up, the x(3) register will not be initialized. The lack of initialization is very unlikely to cause a problem in practice, because all of the following things must happen: 1) An unloaded fun must be called (i.e. the fun must have been received from another node or from a file or dets table). 2) The process must be scheduled out before the call to the error_handler:undefined_lambda/3 function can take place. 3) The process must be garbage collected before the process is scheduled in. 4) The x(3) register must contain a stale cons or box pointer that happens to point into the the heap of the currently executing process. (Because of the literal pool, the GC will never copy anything that is outside of the heap.) I was not able to write a test case that would force an emulator crash.

2011-02-23beam_emu: Remove unnecessary decrement of I in "case_end r"Björn Gustavsson
It is not necessary to decrement I, because an exception is about to be generated. Furthermore, I pointing *before* the instruction that caused the exception may cause problems in the future.
