GCC exception handling flavours and plain C code?

+1 vote
118 views
  1. GCC is available in several variations (SJLJ, DW2, SEH). When compiling plain C code (therefore either assuming or explicitly specifying -fno-exceptions), does it make any difference which GCC variation is used?

  2. Further I assume, that if my plain C code was to link to a C++ library which may throw exceptions, then it would matter which GCC variation I use. In that case, I should use the GCC variation that matches with the C++ code exception flavour, I should enable -fexceptions when compiling my plain C code, and the exceptions could
    then propagate over the C code?

My current compiler settings are

arm-none-eabi-gcc -Wall -mfpu=fpv4-sp-d16 -mfloat-abi=softfp -fshort-double-mcpu=cortex-m4 -mthumb -Qn -Os -finstrument-functions -mlong-calls -c temp.c -o temp.o
so on for temp1, temp2... Etc

I am compiling multiple C files. and linker settings are

ld -r temp.o -o one.o
so on for temp1, temp2... Etc

I am linking multiple .O files. Also I am using linker script i.e link.txt (invoked externally as below)

ld -cref -Map map.txt -S -T link.txt -temp.o -lm -lc -lgcc
arm-none-eabi-gcc -Wall sample.o -O Firmware.abs

Now, At output I get .abs file of 140KB.

My Questions are
1. How to optimize (reduce size of .abs) by using compiler or linker specific options?
2. There are Number of NOT used global variables and Blank Function Calls in my C files (NO Dead Code!!!!). Is it possible to perform some link time optimization.
3. Please Elaborate as I am new to this, I have referred sites, gcc help and tried some "lto" options but NO reduction is size.
4. I also tried using -fdata-sections -ffunction-sections
But It has INCREASED my firmware.abs file size from KB to MB (yes it is MB!!!!) I also wondered WHY?
I am using codesourcery arm toolchain evaluation. It has gcc version 4.5.2

struct xx
{
 int x;
 struct yy *p;
 struct
 {
 int s;
 };
 struct
 {
 int s;
 };    
};

int main()
{    
 struct xx xyz;
 printf("%d",sizeof(xyz));
 return 0;
}

the above code compile well without any warning. Here my question is
1. How can I distinguish two 's' variable.
2. What is use case.
