[sdcc-devel] Problem with .cdb file generated by the linker

[Jesus Calvino-F. <Je...@ec...>]

Hi,

There is a problem, a bug if you will, with the aslink generated cdb file 
for the 8051 port.  Suppose I am linking these four files 'a.rel', 'b.rel', 
'c.rel', and 'd.rel', created after compiling the corresponding C files 
with option --debug.  This also creates the corresponding cdb files for 
each module.  Then the linker (called with option --debug too) combines all 
these cdb files and saves them to 'a.cdb'.  The problem is that if the 
files are linked again, say after recompiling any but the first file 
'a.cdb',  the cdb files are recombined and written to 'a.cdb' 
again.  Therefore 'a.cdb' keeps growing and growing, and of course the 
information it contains becomes redundant and likely incorrect.

One solution to this problem would be to recompile 'a.cdb' anytime one of 
the other files is compiled.  Of course that is not very practical.  Other 
solution would be either to change the linker so it writes the linked cdb 
file with a different extension, say 'ldb', or change the assembler so it 
writes the cdb file with a different extension, say 'adb'.

Any other solutions, preferences, opinions?  Thanks in advance,

Jesus
