/* SUBSECTION |
|
Tektronix Hex Format handling |
|
|
|
DESCRIPTION |
|
|
|
Tek Hex records can hold symbols and data, but not |
|
relocations. Their main application is communication with |
|
devices like PROM programmers and ICE equipment. |
|
|
|
It seems that the sections are described as being really big, |
|
the example I have says that the text section is 0..ffffffff. |
|
BFD would barf with this, many apps would try to alloc 4GB to |
|
read in the file. |
|
|
|
Tex Hex may contain many sections, but the data which comes in |
|
has no tag saying which section it belongs to, so we create |
|
one section for each block of data, called "blknnnn" which we |
|
stick all the data into. |
|
|
|
TekHex may come out of order and there is no header, so an |
|
initial scan is required to discover the minimum and maximum |
|
addresses used to create the vma and size of the sections we |
|
create. |
|
We read in the data into pages of CHUNK_MASK+1 size and read |
|
them out from that whenever we need to. |
|
|
|
Any number of sections may be created for output, we save them |
|
up and output them when it's time to close the bfd. |
|
|
|
A TekHex record looks like: |
|
EXAMPLE |
|
%<block length><type><checksum><stuff><cr> |
|
|
|
DESCRIPTION |
|
Where |
|
o length |
|
is the number of bytes in the record not including the % sign. |
|
o type |
|
is one of: |
|
3) symbol record |
|
6) data record |
|
8) termination record |
|
|
|
The data can come out of order, and may be discontigous. This is a |
|
serial protocol, so big files are unlikely, so we keep a list of 8k chunks. */ |
