22 | // OBSOLETE /* Parse a Chill expression from text in a string, | |
23 | // OBSOLETE and return the result as a struct expression pointer. | |
24 | // OBSOLETE That structure contains arithmetic operations in reverse polish, | |
25 | // OBSOLETE with constants represented by operations that are followed by special data. | |
26 | // OBSOLETE See expression.h for the details of the format. | |
27 | // OBSOLETE What is important here is that it can be built up sequentially | |
28 | // OBSOLETE during the process of parsing; the lower levels of the tree always | |
29 | // OBSOLETE come first in the result. | |
30 | // OBSOLETE | |
31 | // OBSOLETE Note that the language accepted by this parser is more liberal | |
32 | // OBSOLETE than the one accepted by an actual Chill compiler. For example, the | |
33 | // OBSOLETE language rule that a simple name string can not be one of the reserved | |
34 | // OBSOLETE simple name strings is not enforced (e.g "case" is not treated as a | |
35 | // OBSOLETE reserved name). Another example is that Chill is a strongly typed | |
36 | // OBSOLETE language, and certain expressions that violate the type constraints | |
37 | // OBSOLETE may still be evaluated if gdb can do so in a meaningful manner, while | |
38 | // OBSOLETE such expressions would be rejected by the compiler. The reason for | |
39 | // OBSOLETE this more liberal behavior is the philosophy that the debugger | |
40 | // OBSOLETE is intended to be a tool that is used by the programmer when things | |
41 | // OBSOLETE go wrong, and as such, it should provide as few artificial barriers | |
42 | // OBSOLETE to it's use as possible. If it can do something meaningful, even | |
43 | // OBSOLETE something that violates language contraints that are enforced by the | |
44 | // OBSOLETE compiler, it should do so without complaint. | |
