linked in addition to libc rather than instead of libc.
Ideally, "-pthread" would now be equivalent to adding "-lc_r" to the
end of the link command. But it is slightly different in this
implementation. Adding "-lc_r" to the link command would produce a
"ld" command line containing this:
... -lc_r /usr/lib/libgcc.a -lc /usr/lib/libgcc.a ...
but this implementation of the "-pthread" option produces this:
... /usr/lib/libgcc.a -lc_r -lc /usr/lib/libgcc.a ...
It would be possible to make them identical, but that doesn't fit
as nicely into GCC's way of doing things. I don't think the ordering
change will make any difference in practice.
This directory contains machine-specific files for the GNU C compiler. It has a subdirectory for each basic CPU type. The only files in this directory itself are some .h files that pertain to particular operating systems and are used for more than one CPU type.
