Hi,
Does nobody else has problems with the current egcs in the CVS (i.e.,
not the versions on the branch). On ix86 I get a completely unusable
result since the floating-point handling is horribly broken. This is
what enquire prints:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PROPERTIES OF FLOAT
Base = -2147483648
*** WARNING: Function return or parameter passing faulty? (This is a guess.)
PROPERTIES OF DOUBLE
Base = -2147483648
*** WARNING: Function return or parameter passing faulty? (This is a guess.)
PROPERTIES OF LONG DOUBLE
Base = -2147483648
*** WARNING: Function return or parameter passing faulty? (This is a guess.)
Float expressions are evaluated in a higher precision than double,
using 1 base digits
Double expressions are evaluated in a higher precision than double,
using 1 base digits
Long double expressions are evaluated in a higher precision than double,
using 1 base digits
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Another problem is that `make' went on building the compiler.
Shouldn't enquire report this as a severe problem and stop the
compilation?

i686-pc-linux-gnulibc1.
I'm in the process of doing a merge from gcc2 -> egcs, once that's done
I'll be making a fresh snapshot (from the development tree) so other
folks can look into this problem.

Nope -- at least in the past enquire generated warnings/errors on
many systems due to bugs in their C-libraries. It was decreed that
this should not stop the build process.

Mine looks normal.

The compiler builds fine. What does the generated gcc/include/float.h
contain? Mine is empty.
I'll try to update the gcc source tree of egcs. Maybe some unwanted
change crept in.

I used to get this problem on ix86 on older FSF gcc snapshots, if
BOOT_CFLAGS contained -O2 or higher. This is fixed in the current
snapshot; it is possible that Jeff hasn't merged whatever fixed it
yet.

We found out that it's no problem with -O2 but with -O3. I.e., don't run
make CFLAGS=-O3
in the current version.

I just did a merge with the gcc-2.8 tarball, so if it was fixed at
the FSF sources, it should be OK in the mainline tree now...
I'll be making a snapshot of the mainline tree later today.

I just got a clean -O3 build; so it was probably something that got
fixed when I did the merge from gcc-2.8.
