21 | /* Parse a C expression from text in a string, | |
22 | and return the result as a struct expression pointer. | |
23 | That structure contains arithmetic operations in reverse polish, | |
24 | with constants represented by operations that are followed by special data. | |
25 | See expression.h for the details of the format. | |
26 | What is important here is that it can be built up sequentially | |
27 | during the process of parsing; the lower levels of the tree always | |
28 | come first in the result. | |
29 | ||
30 | Note that malloc's and realloc's in this file are transformed to | |
31 | xmalloc and xrealloc respectively by the same sed command in the | |
32 | makefile that remaps any other malloc/realloc inserted by the parser | |
33 | generator. Doing this with #defines and trying to control the interaction | |
34 | with include files (<malloc.h> and <stdlib.h> for example) just became | |
35 | too messy, particularly when such includes can be inserted at random | |
36 | times by the parser generator. */ | |
