rtems-ra supports converting an elf archive file into a rap archive file.
It also support add, replace and delete rap files from the rap archive
file.
|
|
1. Automatically place object files in archive files into a ra file,
using new option --runtime-lib
2. Add a new option --one-file to decide whether the collected
object files should be merged into the rap file or not.

Add an exit label that is called when removing an application.
Change the "applicatiion" to "elf_application" and add a custom
format called the RAP format for applications.

Added support for an RTEMS RAP format application file. The format is:
<header>
<LZ77>
<Application Script>
<[1..n] ELF Object files>
</LZ77>
Where the header is a text string of fields delimited by ',' and terminated
with a line feed (\n). It is variable length:
RTEMS-APP,0000000,01.00.00,LZ77,00000000\n\0
where:
RTEMS-APP : file tag for quick acceptance and rejection
Length : the length of the application in bytes including the
: header
Version : Version of the application format.
Compress : The compression format.
Checksum : CCITT CRC32 checksum.
Following the header is a nul ('\0') character then an LZ77 container
with the application loader script followed by the ELF object files.
Note, the script format will be documented else where.
Note, the final version may add a 32bit length field before each part
in the compressed container to delimit the size of the file to be
read. This is currently not in this version.

If an object on the command line depends on another object the output
code wrote the object files and then the dependent files and a
command line object file that is dependent ended up in the object
and dependent lists. A simple merge and unique fixed it.
Also moved the script generation code into a separate function
that can be used in a application container.
