2011-04-05support new SDKs in find_redist.sh and fallback to $ERL_TOP as last resortDave Cottlehuber
find_redist.sh searches for the matching MS VC++ redistributable runtime in likely places. Patch adds support for MS Windows SDK 7.0 and 7.1, used in VS2008 and VS2010. Also supports putting vcredist_x86.exe in $ERL_TOP/.. or $ERL_TOP

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.

2011-03-24add support for checking if an ERL_NIF_TERM is an exceptionSteve Vinoski
Add the enif_is_exception function to allow callers to determine whether an ERL_NIF_TERM represents an exception. (Currently the only supported exception is badarg since only enif_make_badarg exists, but this will likely be expanded in future releases.) This allows NIF code to call other NIF functions that return ERL_NIF_TERM and properly check to see if the returned terms are exceptions. Without the enif_is_exception function, developers have to create their own means of checking whether a function creates an exception, such as returning boolean success/failure indicators or some other special value indicating that an exception is in effect. The declaration of enif_is_exception in erl_nif_api_funcs.h respects the order of declarations required to keep compatibility on Windows. Add a new test to verify the operation of enif_is_exception. Modify the erl_nif man page to add a description of enif_is_exception and also to clarify the requirements of calling the enif_make_badarg function. If code calls enif_make_badarg, the env passed in gets set with exception information and so the return value of the calling function MUST be the badarg term returned from enif_make_badarg. Also clarify that the result of enif_make_badarg may be passed only to enif_is_exception and not to any other NIF API functions.

If not explicitly enabled, hipe is auto-disabled for halfword emulator. Configuration fails if both are explicitly enabled.

2011-03-09Make halfword emulator with valgrind target allocate low memorySverker Eriksson
Limit ERTS_MSEG_FAKE_SEGMENTS (that is otherwise set for valgrind target) to not apply to low memory needed by halfword emulator. This will reduce the fault detection capability of valgrind for low memory. Also correct a bug in the initial mmap and make sure the returned memory region does not reach into high memory.

* sverker/clarify_nif_resource_doc: clarify NIF resource object deallocation documentation
2011-03-09clarify NIF resource object deallocation documentationSteve Vinoski
In the erl_nif documentation, clarify how and when NIF resource objects can be deallocated. Specifically, add focus for the case of calling enif_release_resource immediately after obtaining a resource term from enif_make_resource, since this is likely to be a common approach NIFs use to manage resources. Also fix a couple misspellings in the erl_nif documentation.
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.
