Passing -auxbase to cc1 thru gcc

[Clifford Wolf]

Hi,

I'm using gcc 3.4.2 and I have the following problem with it:

Usually the -auxbase option to cc1 is autogenerated from the specs file. So
e.g. the gcc call "gcc-34 -v -fprofile-arcs demo.c" results in something
such as:

/usr/libexec/gcc/i386-unknown-linux-gnu/3.4.2/cc1 -quiet -v demo.c -quiet \
  -dumpbase demo.c -auxbase demo -version -fprofile-arcs -o /tmp/ccTzVYVe.s

The "-auxbase demo" is added from the specs file:

%{c|S:%{o*:-auxbase-strip %*}%{!o*:-auxbase %b}}%{!c:%{!S:-auxbase %b}}

So I want to set my own auxbase using something like:

	gcc-34 -v -auxbase /tmp/myprofile/demo -fprofile-arcs demo.c

But this is then converted by gcc to:

gcc-34: /tmp/myprofile/demo: No such file or directory

/usr/libexec/gcc/i386-unknown-linux-gnu/3.4.2/cc1 -quiet -v demo.c -quiet \
-dumpbase demo.c -auxbase -auxbase demo -version-fprofile-arcs -o /tmp/ccezahKk.s

So, because gcc doesn't know -auxbase it just passes it thru to cc1. But
since it doesn't know that -auxbase takes an argument, it simply thinks
that /tmp/myprofile/demo is just another source file..

Should setting -auxbase from the gcc command line be supported? (I've found
the option from reading the gcc sources - there seams to be no
documentation about it.)

Am I doing something wrong or is that a bug in gcc?

yours,
 - clifford
