When I configure with --disable-bootstrap and build with:
CFLAGS="-g -O0"
The resultant compiler is built with the specified options. However, if
I --enable-bootstrap, when I build with the same CFLAGS, these options
are not used to build the final compiler. I can get past this by usin
Checks for vector instruction support are spreading throughout the

This snapshot has been generated from the GCC 4.0 SVN branch

Congratulations and thanks for your work. I could not do any GCC
development without it.
Thanks,

Note that configure options beginning with --with and --enable are
passed from the top level configure script to the subdirectory
configure scripts. So the user just uses all the options at the top
level, and the subdirectories will see them.
I did notice this, but it seems to me (maybe I am

No, you shouldn't. Only add them to subdirs that need them.

No if you use only one compiler (i.e. the multilibbed 32-bit compiler).

I just built and locally installed gcc's (infrastructure) tarballs of
gmp-4.2.1 and mpfr-2.2.1 to try to build gcc trunk (as my build
system's versions are too old).
But, I am on a UltraSPARC system so I test build gcc multilibbed
enabled to have both 32 and 64 bit capability.
So, my question is
Hello,
Most options of GCC (like --enable-werror --with-gmp ...) are configure-able
at its toplevel source directory while others ( --enable-mapped-location
) are configure-able with the configure script inside its gcc/ source
subdirectory
Of course, some options are for the whole toplevel.
loop anyway... you C++ people tend to overtax compiler with
optimizations. Is it really necessary to do (i == j) * factor
when (i == j) ? factor : 0 is easier for compiler to grok?
Of course I tried it. It's even slower. Doesn't help the compiler unroll the
loop, and now there's a branch at e
