We're targeting a new OS with GCC. I've done some of these before, but
I've run into one issue I don't recognize, and a second that I have
obviously messed up. I have looked at "Using and Porting" and "GCC
Internals". The answers may be there, but I did not find them --
pointers welcome.
1. Versions of crtbegin
There are three versions of crtbegin: crtbegin.o, crtbeginS.o,
crtbeginT.o. 'S' is for shared/PIE -- I understand about that. Can
somebody explain what the distinction is between crtbeginT.o and
crtbegin.o?
2. Is there a simple way to configure the compiler so that the default
compilation model (in the absence of command-line directives) is
--static? If not, which of the various specfile macros need to be
updated? I know how to write specfile lines, I just want to make sure
that I don't miss one somewhere.
3. At least on i386, there are GOT sections appearing in
crt{begin,end}.o and libgcc.a. Our target does not have any dynamic
linking/loading support AT ALL. Are these sections fully resolved after
link time?
Thanks
