there was no response to the above, so i've put together a script that
attempts to extract this information from the .rel files for our 8051
project.
the output of my script looks like this:
$ tools/sdcc_sizes

-- totals (no libraries) --------
code: 29522
const: 4679
xdata: 798
data: 52
bits: 9
the .mem file for this build says:
Other memory:
Name Start End Size Max
---------------- -------- -------- -------- --------
PAGED EXT. RAM 0 256
EXTERNAL RAM 0xf400 0xf773 884 2048
ROM/EPROM/FLASH 0x0000 0x9454 37973 62464
the difference between the ROM/EPROM/FLASH value of 37973 and
my code+const value of 29522+4679 ( == 34201) is 3772. does
that seem like a reasonable size for the library code? i think
printf_large is roughly 1K, so maybe it's about right.
the script i'm using is attached. comments/corrections welcome, of course.
