24 | Tektronix Hex Format handling | |
25 | ||
26 | DESCRIPTION | |
27 | ||
28 | Tek Hex records can hold symbols and data, but not | |
29 | relocations. Their main application is communication with | |
30 | devices like PROM programmers and ICE equipment. | |
31 | ||
32 | It seems that the sections are descibed as being really big, | |
33 | the example I have says that the text section is 0..ffffffff. | |
34 | BFD would barf with this, many apps would try to alloc 4GB to | |
35 | read in the file. | |
36 | ||
37 | Tex Hex may contain many sections, but the data which comes in | |
38 | has no tag saying which section it belongs to, so we create | |
39 | one section for each block of data, called "blknnnn" which we | |
40 | stick all the data into. | |
41 | ||
42 | TekHex may come out of order and there is no header, so an | |
43 | initial scan is required to discover the minimum and maximum | |
44 | addresses used to create the vma and size of the sections we | |
45 | create. | |
46 | We read in the data into pages of CHUNK_MASK+1 size and read | |
47 | them out from that whenever we need to. | |
48 | ||
49 | Any number of sections may be created for output, we save them | |
50 | up and output them when it's time to close the bfd. | |
51 | ||
52 | ||
53 | A TekHex record looks like: | |
54 | EXAMPLE | |
55 | %<block length><type><checksum><stuff><cr> | |
56 | ||
57 | DESCRIPTION | |
58 | Where | |
59 | o length | |
60 | is the number of bytes in the record not including the % sign. | |
61 | o type | |
62 | is one of: | |
63 | 3) symbol record | |
64 | 6) data record | |
65 | 8) termination record | |
66 | ||
67 | ||
68 | The data can come out of order, and may be discontigous. This is a | |
69 | serial protocol, so big files are unlikely, so we keep a list of 8k chunks | |
