__gccmain

[Dainius]

Hello,

  I made ARM-ELF compiler. I tryed simple source to compile:

  int main()
  {  while (1);
  }

  I compiled it to make ASM code with following line:
  arm-elf-gcc -o test.asm -S test1.c

  And short ASM code was :
...
main:   @ args = 0, pretend = 0, frame = 0
        @ frame_needed = 1, current_function_anonymous_args = 0
        mov     ip, sp
        stmfd   sp!, {fp, ip, lr, pc}
        sub     fp, ip, #4
        bl      __gccmain
.L2:    b       .L2
.Lfe1: .size   main,.Lfe1-main

But after:
  arm-elf-as -o test.o test.asm
  arm-elf-ld -o test.bin -e main test.o

  I got error: test.o<.text+0xc>: undefined reference to '__gccmain'

  What to do, that GCC would not generate __gccmain reference? Or how
to solve it, that linker would understand it?
  After removing this reference manualy (from ASM file), linker
worked. But I hope exists better solutions...

  My used GCC version is 3.0

  Thanks in advance.
