Hello, I write code for Tiny13 embedded applications using 'C' to improve maintainability. Due to some small issues I decided to update my entire toolchain to the latest (greatest?) versions. Upon going back to some old projects I notice that re-compiling makes the code grow quite horribly. In one case the 'main' function has increased from it's original 0x10c Bytes to 0x15c Bytes (ca. 30%). This was especially apparent because the code would no longer fit in the target device (1024 Bytes). On inspection I find that the compiler has 'in-lined' at least 3 function calls that I had written as a function to achieve compactness. Is there any way I can stop this, or is this a bug?
I am using: avr-gcc compiled from gcc-core-4.3.2 binutils-2.19 avr-libc-1.6.4 My Makefile: PRG = ES04 OBJ = $(PRG).o MCU_TARGET = attiny13 OPTIMIZE = -Os DEFS = LIBS = CC = avr-gcc override CFLAGS = -g -Wall -Wno-main $(OPTIMIZE) -mmcu=$(MCU_TARGET) $(DEFS) override LDFLAGS = -Wl,-Map,$(PRG).map -Wl,--section-start=.testparms=0x880 <snip> I would appreciate any thoughts before I think about returning to the old compiler (whose version I have, of course, forgotten). I imagine there will be quite a few people interested in small devices who also will get bitten here.
