include/gdb is for building gcc and gdb, not for building target
programs. Consider a cross-compiler + cross-debugger + simulator:
host=i686-pc-linux-gnu, target=rs6000-unknown-whatever. So that
directory is right out.
gcc should be installing altivec.h with the other target include files.
AldyH would know about that.
Perhaps you are testing out of a build directory, rather than an install
directory, and the dejagnu machinery is not producing enough -I flags?
(I am studying this area right now because I'm working on Petr's
f77/f95 patch).
Suggestion:
I did a find in the gcc source:
% find * -name '*altivec*' -print
gcc/config/rs6000/altivec.h
gcc/config/rs6000/altivec-defs.h
gcc/config/rs6000/eabialtivec.h
gcc/config/rs6000/linuxaltivec.h
gcc/testsuite/gcc.dg/altivec-1.c
gcc/testsuite/gcc.dg/altivec-2.c
gcc/testsuite/gcc.dg/altivec-3.c
gcc/testsuite/gcc.dg/altivec-4.c
gcc/testsuite/gcc.dg/altivec-5.c
gcc/testsuite/gcc.dg/altivec-7.c
gcc/testsuite/gcc.dg/altivec-8.c
Most of the altivec-*.c test files do not use altivec.h. They simply
use builtin keywords directly. Have a look at altivec-4.c.
You could write the tests like that.
