Creating section symbols using the -objsym command
Example using block symbols in the assembly source
S5U1C33000C MANUAL
(C COMPILER PACKAGE FOR S1C33 FAMILY) (Ver. 4)
When the -objsym command is written in a command file, the lk33 generates the following symbols for
each section in each input file to indicate section information after relocation:
_ _ START_<File name>_<Section>
_ _ END_<File name>_<Section>
_ _ SIZEOF_<File name>_<Section> Defines the size (in bytes) of a relocated section.
Example: If the input file name is "test.o", the start address of the CODE section is 0x0c00000, and the size
The path and extension of <File name> are cut irrespective of how they are written in a command file. The
start address and size defined to a symbol are the same as the contents output to the link map file (real data
address), and the end address is determined by the "start address" + "size".
Example: When transferring the OBJ1 block to virtual block "CACHE1"
