Bootstrap broken on sparc-linux trunk between 145310:145425 because of new genattrtab.c va_arg (p, HOST_WIDE_INT) warning

[Laurent GUERBY <laurent at guerby dot net>]

Hi,

On sparc-linux gcc54 I get at rev 145425:

/home/guerby/build/./prev-gcc/xgcc -B/home/guerby/build/./prev-gcc/ -B/n/54/guerby/install-trunk/sparc64-unknown-linux-gnu/bin/ -c  -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-p\

make[1]: *** [stage2-bubble] Error 2

make: *** [bootstrap] Error 2

Both warnings are on the same type of code:

HOST_WIDE_INT arg0 = va_arg (p, HOST_WIDE_INT);

va_arg (p, HOST_WIDE_INT)

It was working at rev 145310, lots of change so hard to guess which
one caused the failure.

I'm thinking of changing my auto tester to report a broken bootstrap
(the first time a bootstrap fails), is there a normalized way to
report such failures to gcc-testresults@ or gcc@?

+
+	* loop-iv.c (suitable_set_for_replacement): Renamed from
+	simplify_using_assignment; changed to return bool and to accept new
+	args DEST and SRC.  Return true iff we find a source/destination pair
+	that can be used to make a replacement, and fill SRC and DEST if so.
+	Remove arg ALTERED.  Don't deal with altered regs here.  All callers
+	changed.
+	(simplify_using_initial_values): Deal with altered regs here and track
+	more precisely the effect they have on the validity of our expression.
+
+	* loop-iv.c (simplify_using_condition): A condition of the form
+	(EQ REG CONST) can be used to simply make a substitution.

+
+	* loop-iv.c (determine_max_iter): New arg OLD_NITER.  All callers
+	changed.  Use this when trying to improve the upper bound.
+	Generate the comparison by using simplify_gen_relational.
