Hello Today I tried to recompile an old project for a pic16f690 and the thing was suddenly too big too fit in the pic : error: no target memory available for section "code_happyhourjuhe"
As I changed some of the code I tried to reduce the size, but I had to remove the complete main function (half of the code) to make it compile. After some drinking I had the idea to try the old compiler version I was using back in 2011. Here's a comparison of the estimated file sizes for different sdcc versions. SDCC : pic16/pic14 3.4.0/*rc1*/ #8960 (Mar 10 2014) bin/obj/EEPROM.asm ; 22+ 12 = 34 instructions ( 92 byte) bin/obj/Globals_DEF.asm ; 0+ 0 = 0 instructions ( 0 byte) bin/obj/I2C_adapter.asm ; 1061+ 355 = 1416 instructions ( 3542 byte) bin/obj/I2C_slave.asm ; 164+ 61 = 225 instructions ( 572 byte) bin/obj/IncSwitch.asm ; 23+ 7 = 30 instructions ( 74 byte) bin/obj/main.asm ; 1060+ 371 = 1431 instructions ( 3604 byte) bin/obj/ServoFunctions.asm ; 102+ 32 = 134 instructions ( 332 byte) bin/obj/StoreLoadValues.asm ; 231+ 73 = 304 instructions ( 754 byte) SDCC 3.0.1 release in/obj/EEPROM.asm ; 22+ 12 = 34 instructions ( 92 byte) bin/obj/Globals_DEF.asm ; 0+ 0 = 0 instructions ( 0 byte) bin/obj/I2C_adapter.asm ; 917+ 313 = 1230 instructions ( 3086 byte) bin/obj/I2C_slave.asm ; 155+ 60 = 215 instructions ( 550 byte) bin/obj/IncSwitch.asm ; 23+ 7 = 30 instructions ( 74 byte) bin/obj/main.asm ; 1041+ 352 = 1393 instructions ( 3490 byte) bin/obj/ServoFunctions.asm ; 102+ 32 = 134 instructions ( 332 byte) bin/obj/StoreLoadValues.asm ; 240+ 73 = 313 instructions ( 772 byte) SDCC 3.0.0 release bin/obj/EEPROM.asm ; 22+ 12 = 34 instructions ( 92 byte) bin/obj/Globals_DEF.asm ; 0+ 0 = 0 instructions ( 0 byte) bin/obj/I2C_adapter.asm ; 916+ 175 = 1091 instructions ( 2532 byte) bin/obj/I2C_slave.asm ; 155+ 54 = 209 instructions ( 526 byte) bin/obj/IncSwitch.asm ; 23+ 7 = 30 instructions ( 74 byte) bin/obj/main.asm ; 1030+ 201 = 1231 instructions ( 2864 byte) bin/obj/ServoFunctions.asm ; 100+ 28 = 128 instructions ( 312 byte) bin/obj/StoreLoadValues.asm ; 242+ 41 = 283 instructions ( 648 byte) As you can see, the estimated file size of main.asm for example increases by ~20% from version 3.0.0 (2.8 kb) to version 3.0.1 (3.4kb) and another ~3% from version 3.0.1 to the version I last pulled from svn (3.6 kB). Did you introduce some new optimisation switches since version 3.0.0 or changed default libraries or stuff? The commandline I'm currently using looks like this : sdcc -o bin/obj/main.o -mpic14 -p16f690 -D__16F690__ --use-non-free --opt-code-speed -I./src -I../../lib/16F690 -c -c src/main.c (the opt-code-speed or size switch does the same as ever, nothing) The code compiles fine with version 3.0.0.
