2013-05-31asn1_constructed_per: Optimize decoding of CHOICEBjörn Gustavsson
Optimize the decoding of CHOICE. Most important is to inline decoding of the extension bit (if present) and decoding of the choice index to give the BEAM compiler more opportunities for optimization. We will also change the structure of the generated code. The current code uses a flattened case for both the root and extension alternatives: case Choice + NumRootChoices * Ext of %% Root alternatives. 0 - ...; : LastRootAlternative -> ...; %% Extension alternatives. LastRootAlternative+1 -> ...; : %% Unknown extension. _ -> ...; end We will instead generate nested cases: case Ext of 0 -> case Choice of %% Root alternatives. 0 - ...; : LastRootAlternative -> ... end; 1 -> %% Extension alternatives. <Decode the open type here> case Choice of 0 -> ...; : LastExtensionAlternative -> ...; %% Unknown extension. _ -> ...; end end Nested cases should be slightly faster. For decoding of the extensions, it also makes it possible to hoist the decoding of the open type up from each case to before the case switching on the extension index, thus reducing the size of the generated code. We will also do another change to the structure. Currently, the big flat clase is wrapped in code that repackages the return values: {Alt,{Value,RemainingEncodedData}} = case Choice + NumRootChoices * Ext of : end, {{Value,Alt},RemainingEncodedData}. We still need to do the repackaging, but we can push it down to the case arm for decoding each alternative. In many cases, that will give the BEAM compiler the opportunity to avoid building the temporary tuples.

2010-03-11asn1 tests: Don't refer to $ERL_TOP in compiler optionsBjörn Gustavsson
On Windows, $ERL_TOP contains a cygwin-style pathname that can be used in Makefiles to (for instance) include other Makefiles, but must not be passed to non-cygwin programs such as "erlc". Therefore, using compiler options such as "-I $(ERL_TOP)/lib/test_server/include" will not work on Windows. Fix this problem by include "test_server.hrl" using -include_lib() instead of -include(). That works because -include_lib() searches for include files in the code path without the need for any -I options.
