* Initialize the ob_type field of PyAST_Type dynamically (inGuido van Rossum1997-01-231-3/+7
| | | | | | | | | initparser()) instead of statically (in the initializer). The static initialization, using the address of an object in a different DLL, is too much for the Microsoft VC++ compiler, and we want to be able to build this module as a separate DLL (it's nice to have but we don't want to increase the core DLL's size by 25K). This same trick has been applied to a number of modules, e.g. NumPy and _tkinter.

| | | | | | | | | | - -mt option for Solaris threads with Solaris compiler - make clean when switching static link status for Linux - DEC alpha --with-dec-threads option - SunOS removed unnecessary warnings, mention -Xa for SunPro - Setup.local file - warn to try make clean after changing readline option - mention --with-threads as alias for --with-thread

* Only call sigcheck() at the ticker code if we don't have true signals.Guido van Rossum1997-01-211-2/+6
| | | | | | | This is safe now that both intrcheck() and signalmodule.c schedule a sigcheck() call via Py_AddPendingCall(). This gives another 7% speedup (never run such a test twice ;-).
* Arrange for PyErr_CheckSignals() to be called via Py_AddPendingCall().Guido van Rossum1997-01-211-1/+3
| | | | | This avoids having to call sigcheck() (the same routine by its old name :-) in the ticker code in ceval.c's main interpreter loop.
* In the Unix version, arrange for sigcheck() to be called viaGuido van Rossum1997-01-211-0/+3

* Cleanup:Guido van Rossum1997-01-211-222/+10
| | | | | | | | | | - fix bug in Py_MakePendingCalls() with threading - fix return type of do_raise - remove build_slice (same as PySlice_New) - remove code inside #if 0 - remove code inside #ifdef CHECK_STACK - remove code inside #ifdef SUPPORT_OBSOLETE_ACCESS - comment about newimp.py should refer to ni.py

|
* Changes for frame object speedup:Guido van Rossum1997-01-201-14/+2
| | | | | | - get fastlocals differently - call newframeobject() with fewer arguments - toss getowner(), which was unused anyway
* Changes that appear to give another 12% speedup.Guido van Rossum1997-01-201-87/+55
| | | | | | | | | | | | Rather than allocating a list object for the fast locals and another (extensible one) for the value stack and allocating the block stack dynamically, allocate the block stack with a fixed size (CO_MAXBLOCKS from compile.h), and stick the locals and value stack at the end of the object (this is now possible since the stack size is known beforehand). Get rid of the owner field and the nvalues argument -- it is available in the code object, like nlocals. This requires small changes in ceval.c only.
* New lay-out of frame object, for fewer mallocs.Guido van Rossum1997-01-201-9/+8

* Two speedup hacks. Caching the hash saves recalculation of a string'sGuido van Rossum1997-01-181-3/+23
| | | | | | | | | | hash value. Interning strings (which requires hash caching) tries to ensure that only one string object with a given value exists, so equality tests are one pointer comparison. Together, these can speed the interpreter up by as much as 20%. Each costs the size of a long or pointer per string object. In addition, interned strings live until the end of times. If you are concerned about memory footprint, simply comment the #define out here (and rebuild everything!).
* Add "if (x != NULL) continue;" (or similar for err==0) before theGuido van Rossum1997-01-181-18/+60
