More ld script questions..
2004-01-22 by James Dabbs
In the file <lpc2106-rom.ld>, from the file <lpc2106_gcc.zip> on the
yahoo site..
in the prog output section, there are these entries:
*(.rodata)
*(.rodata*)
I understand that the first means "add the entire contents of the
.rodata input segment into the prog output segment," but what is the
function of that second entry with the asterisk after it?
For reference, I've appended the linker script in its entirety.
Thanks for any guidance.
