aCC option to load all the symbols during linking
|
|
|
Hi,
Is there any option for aCC compiler to load all the symbols during
linking (with +O2 option enable)?
When I create an executable with +O2 option, it is not loading all the
functions into the executable (Not loading functions that are not
called in the execution).
But I want to have all the functions(symbols) loaded during the
creation of the executable.
Thanks,
Bujji |

No: aCC doesn't *do* linking; the system linker does that.

Presumably you are linking with archive libraries, and you want
the equivalent of the GNU-ld --whole-archive ...
AFAICT, there is no matching HP ld flag.
One way to achive that is to list all symbols you want to be included
in the link with '-u sym1 -u sym2 ...'
Another option is to "blow up" the archive:
mkdir tmp.$$ && cd tmp.$$ &&
ar x /path/to/archive.a &&
cd .. && aCC -o foo.exe main.o tmp.$$/*.o &&
rm -rf tmp.$$

There is +[no]forceload for IPF and PA64. And -Fl for PA32.

Yes.
