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