I wrote a simple hello.c

#include <stdio.h>

main()
{
    printf("Hello World!\n");
}

And compiled it with gcc-2.7.2 , egcs-1.0.1(haifa enabled) and
egcs-1.02-980309-prerelease(haifa disabled)

The following are the file sizes and the output of size -f

----------------------------------------------------------------------
gcc-2.7.2
Size:			5440 bytes
% size -f foo

17(.interp) + 300(.hash) + 672(.dynsym) + 188(.dynstr) +
32(.SUNW_version) + 12(.rela.bss) + 48(.rela.plt) + 352(.text) +
20(.init) + 20(.fini) + 22(.rodata) + 12(.got) + 152(.dynamic) +
100(.plt) + 0(.data) + 8(.ctors) + 8(.dtors) + 4(.bss) = 1967

----------------------------------------------------------------------
egcs-1.0.1
Size:			24952 bytes
% size -f foo


17(.interp) + 460(.hash) + 960(.dynsym) + 391(.dynstr) +
32(.SUNW_version) + 12(.rela.bss) + 144(.rela.plt) + 3344(.text) +
28(.init) + 20(.fini) + 35(.rodata) + 36(.got) + 152(.dynamic) +
196(.plt) + 8(.data) + 8(.ctors) + 8(.dtors) + 424(.eh_frame) +
32(.bss) = 6307

----------------------------------------------------------------------
egcs-1.0.2-980308-prerelease
Size:			25016 bytes
% size -f foo

17(.interp) + 460(.hash) + 960(.dynsym) + 391(.dynstr) +
32(.SUNW_version) + 12(.rela.bss) + 144(.rela.plt) + 3376(.text) +
28(.init) + 20(.fini) + 35(.rodata) + 36(.got) + 152(.dynamic) +
196(.plt) + 8(.data) + 8(.ctors) + 8(.dtors) + 424(.eh_frame) +
32(.bss) = 6339

Compile command was gcc -o foo foo.c

Is this expected behaviour. Why is there such an increase in
executable code size. I have not looked at other platforms yet

Cheers, Yusuf

In http://www.cygnus.com/ml/egcs/1998-Mar/0391.html , Jason Merril
<jason@cygnus.com> suggested using GNU ld. 

I compiled binutils-2.9 with a patch from Ian Taylor <ian@cygnus.com>
posted on gnu.utils.bug to prevent strip from dumping core and then
compiled egcs-1.0.2 with --with-gnu-as and --with-gnu-ld and
--enable-haifa. The results are around the same as using egcs-1.0.2
with the native assembler and linker. Compared to gcc-2.7.2.3, the
code size increase for Hello World is 4x.

gcc version egcs-2.90.27 980315 (egcs-1.0.2 release) on
sparc-sun-solaris2.6 

I haven't checked if this problem has been solved in the recent
snapshots. Can somebody who has the recent snapshots on
sparc-sun-solaris2.6 let us know ? 

Here's the test program

#include <stdio.h>

int main(int argc, char *argv[])
{
    printf("Hello World!\n");
         return 0;
}

Thanks, Yusuf

Oops, forgot to mention that the platform is sparc-sun-solaris2.6,
specifically I am using an Ultrasparc-1

Cheers, Yusuf
