Topic: Sequence points


  
  Sequence point - Wikipedia, the free encyclopedia
A sequence point in a programming language defines any point in a computer program's execution at which it is guaranteed that all side effects of previous evaluations will have been performed, and no side effects from subsequent evaluations have yet been performed.
They are often mentioned in reference to C and C++, because the result of some expressions can depend on the order of evaluation (adding one or more sequence points is one method of ensuring a consistent result, because this restricts the possible orders of evaluation).
The order in which the arguments are evaluated is not defined, but this sequence point just means that all of their side effects are complete before the function is entered.

 PlanetMath: limit points of sequences
It is worth noting that the set of limit points of a sequence can differ from the set of limit points of the set of elements of the sequence.
Likewise the set of accumulation points of a sequence can differ from the set of accumulation points of the set of elements of the sequence.
This is version 4 of limit points of sequences, born on 2004-09-24, modified 2005-03-02.

Thus, the object 'x' is modified twice between sequence points.
Thus, you have to look for sequence points and this is all: Only at sequence points objects are in a well defined state.
Also, whether the assignment is finished or not is absolutely irrelevant: Modifying an object twice between sequence points is undefined behavior (clearly stated in the DWP).

 Embedded.com - Sequence Points
A sequence point is any point in a program's execution wherein all side effects of previous evaluations are complete and no side effects of subsequent evaluations have started.
Sequence points also appear at the end of the controlling expression of an if or switch statement, the controlling expression of a while or do statement, and each of the expressions of a for statement.
Although the comma operator is a sequence point, the commas that separate the arguments in a function call are not comma operators; they're just punctuation.

Sequence architecture is controlled by two fundamental factors; the water level relative to the depositional surface (which controls accommodation space), and the points or areas of sediment injection (which control how this space is filled in).
Furthermore, injection points are controlled not only by lake level but by the terminus of the glacier: during high lake levels the injection point of the glacier may be underwater at the base of the slope.
Sequences are controlled by two factors; the water level relative to the depositional surface (which controls accommodation space), and the points or areas of sediment injection (which control how this space is filled in) (Vail, 1987) (Fig.

 Side Effects and Sequence Points   (Site not responding. Last check: 2007-10-06)
The actual order in which expressions are evaluated is not specified for most of the operators in C. Because this sequence of evaluation is determined within the compiler depending on context, some unexpected results may occur when using certain operators.
Sequence points are checkpoints in the program at which the compiler ensures that operations in an expression are concluded.
The most important sequence point is the semicolon marking the end of a statement.

Sequence 0 (as numbered below in the section 'Sequence indexing', is the starting move of the scene.
So, as an example: 0x84 means jump to the death sequence if the user moves left, and 0x98 means jump to the next sequence (or end of scene), if the user moves right.

For the sequence query, the doctype DTD is "http://www.biodas.org/dtd/dassequence.dtd".
The request for a named segment may fail because: (1) the reference sequence is not known to the server or (2) the requested region is outside the bounds of the segment.
This situation is complicated by rough draft issues, in which a single rough draft sequence segment may have multiple parents, and some sections of the segment may not belong in the assembly at all.

 Rick Byers : DebuggingModes.IgnoreSymbolStoreSequencePoints
A sequence point is used to mark a spot in the IL code that corresponds to a specific location in the original source.
Since they're only needed for debugging scenarios, the location of sequence points, and their mapping back to source locations, are stored in the PDB file.
Now in addition to the sequence points specified in the PDB file ("explicit sequence points"), the JIT also infers additional sequence points based on the IL code ("implicit sequence points").

It is possible for each entry point to have a substructure, basically a series of subsequences and their starting and ending points.
If a sequence reference ID is provided in the ref argument, the query will return the components of the sequence (its subsequences) rather than the list of top-level entry point sequences.
If the entry points are not "top level", that is, if they were generated by a request for the substructure of a sequence, then the ref attribute will be present and will indicate the ID of the reference sequence.

My suggested way to add debugger support for FeeFee is to have the debugger find all FeeFee ranges in the current method and then add those to the step ranges passed into ICorDebugStepper::Step (that’s how we added it to Cordbg).
