950361c6ca Patches for (two forms of) optional dynamic execution profiling -- 
i.e., counting opcode frequencies, or (with DXPAIRS defined) opcode
pair frequencies.  Define DYNAMIC_EXECUTION_PROFILE on the command
line (for this file and for sysmodule.c) to enable.

8c5df06ec7 Change the control flow for error handling in the function prelude to 
jump to the "Kill locals" section at the end.  Add #ifdef macintosh
bandaid to make sure we call sigcheck() on the Mac.

43f1b8d6e4 Added optional interface for dynamic execution profile (to be gathered 
in ceval.c).

b3f515af64 Get the line number from PyCode_Addr2Line instead of believing 
tb_lineno.  Store it in tb_lineno for the user.

da4eb5c3b5 Instead of emitting SET_LINENO instructions, generate a line number 
table which is incorporated in the code object.  This way, the runtime
overhead to keep track of line numbers is only incurred when an
exception has to be reported.

a4240132ec Kill all local variables on function return. This closes a gigantic 
leak of memory and file descriptors (thanks for Roj for reporting
that!).  Alas, the speed goes down by 5%. :-(

70d44787a3 Only call sigcheck() at the ticker code if we don't have true signals. 
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 ;-).

1aa14838d2 Cleanup: 
- 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

768360243a Changes for frame object speedup: 
- get fastlocals differently
- call newframeobject() with fewer arguments
- toss getowner(), which was unused anyway

7b89b6a660 Intern all names and varnames in newcodeobject(), plus those string 
literals that look like identifiers.  Also intern all strings used as
names during the compilation.

3dfd53b4c8 Add "if (x != NULL) continue;" (or similar for err==0) before the 
break to most cases, as suggested by Tim Peters.  This gives another
8-10% speedup.

62f7d15d0b Use the stack size from the code object and the CO_MAXBLOCKS constant 
from compile.h.  Remove all eval stack overflow checks.
 1997-01-17 21:05:28 +00:00
Guido van Rossum
8b993a98db Add co_stacksize field to codeobject structure, and stacksize argument 
to PyCode_New() argument list.  Move MAXBLOCKS constant to conpile.h.

Added accurate calculation of the actual stack size needed by the
generated code.

Also commented out all fprintf statements (except for a new one to
diagnose stack underflow, and one in #ifdef'ed out code), and added
some new TO DO suggestions (now that the stacksize is taken of the TO
DO list).

0aa9ee65ab Moved the raise logic out of the main interpreter loop to a separate function. 
The raise logic has one additional feature: if you raise <class>,
<value> where <value> is not an instance, it will construct an
instance using <value> as argument.  If <value> is None, <class> is
instantiated without arguments.  If <value> is a tuple, it is used as
the argument list.

This feature is intended to make it easier to upgrade code from using
string exceptions to using class exceptions; without this feature,
you'd have to change every raise statement from ``raise X'' to ``raise
X()'' and from ``raise X, y'' to ``raise X(y)''.  The latter is still
the recommended form (because it has no ambiguities about the number
of arguments), but this change makes the transition less painful.

base class is special it gets invoked.

b0c168cbe8 Tentative changes to make this work better on 64-bit machines. 
A plain int that doesn't fit in 32 bits will be marshalled using a new
type.  32 bits machines can't handle this and will issue a warning.

Guido van Rossum
e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should 
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
