23 | Tektronix Hex Format handling |

116c20d2 | 25 | DESCRIPTION |

252b5132 RH |
27 | Tek Hex records can hold symbols and data, but not |
28 | relocations. Their main application is communication with | |
29 | devices like PROM programmers and ICE equipment. | |
5bff4f56 | 30 | |
7dee875e | 31 | It seems that the sections are described as being really big, |
252b5132 RH |
32 | the example I have says that the text section is 0..ffffffff. |
33 | BFD would barf with this, many apps would try to alloc 4GB to | |
34 | read in the file. | |
35 | ||
36 | Tex Hex may contain many sections, but the data which comes in | |
37 | has no tag saying which section it belongs to, so we create | |
38 | one section for each block of data, called "blknnnn" which we | |
39 | stick all the data into. | |
40 | ||
41 | TekHex may come out of order and there is no header, so an | |
42 | initial scan is required to discover the minimum and maximum | |
43 | addresses used to create the vma and size of the sections we | |
44 | create. | |
45 | We read in the data into pages of CHUNK_MASK+1 size and read | |
46 | them out from that whenever we need to. | |
47 | ||
48 | Any number of sections may be created for output, we save them | |
49 | up and output them when it's time to close the bfd. | |
50 | ||
252b5132 | 51 | A TekHex record looks like: |

116c20d2 | 55 | DESCRIPTION |
252b5132 RH |
56 | Where |
57 | o length | |
58 | is the number of bytes in the record not including the % sign. | |
59 | o type | |
60 | is one of: | |
61 | 3) symbol record | |
62 | 6) data record | |
63 | 8) termination record | |
252b5132 | 64 | |
116c20d2 NC |
65 | The data can come out of order, and may be discontigous. This is a |
66 | serial protocol, so big files are unlikely, so we keep a list of 8k chunks. */ | |
