A test with an empty main compiled using gcc-4 under cygwin-1.7.0-63
has a size of 6.5K. After downgrading to 1.7.0-62, without changing
anything else, the size goes down to 5.0K.
$ cat test.c
int main(void)
{
return 0;
}
$ gcc test.c -Os -s
Looking at objdump differences, both code and data size have gone up:
< SizeOfCode 00000800
< SizeOfInitializedData 00001000
---
> SizeOfCode 00000e00
> SizeOfInitializedData 00001600
And we're pulling in a bunch of additional functions from cygwin1.dll
and kernel32.dll:
> 515c 666 abort
> 5170 788 cygwin_create_path
> 51b0 812 dll_dllcrt0
> 51d4 1221 memcpy
> 51ec 1620 strlen
> 51f8 1742 vsnprintf
> 5238 336 GetModuleFileNameW
> 5274 388 GetStdHandle
> 5284 798 VirtualProtect
> 5296 801 VirtualQuery
> 52a6 827 WriteFile
Obviously 1.5K isn't much of a concern, but is this expected?
