Heh, having the time to do that would be nice. A cursory look at
the .diff files doesn't reveal anything blatantly obvious. Only
three potential candidates:
+2002-10-04 Roger Sayle <roger@eyesopen.com>
+
+ * config/i386/i386.h (processor_costs): Add new fields fadd,
+ fmul, fdiv, fabs, fchs and fsqrt to costs structure.
+ (RTX_COSTS): Use these fields to determine the RTX costs
+ of floating point addition/subtraction, multiplication,
+ division, fabs, negation and square root respectively.
+ * config/i386/i386.c (size_cost): Provide instruction sizes
+ for these new fields.
+ (i386_cost, i486_cost, pentium_cost, pentiumpro_cost,
+ k6_cost, athlon_cost, pentium4_cost): Provide typical cycle
+ counts for these new fields for all x86 processor variants.
+
+2002-10-04 Richard Henderson <rth@redhat.com>
+
+ * real.h (SIGNIFICAND_BITS): Add one more word.
+ (CONST_DOUBLE_FORMAT): Accomodate 6 words.
+ * real.c (times_pten): New.
+ (real_to_decimal, real_from_string): Use it.
+ (sticky_rshift_significand): Use & to find modulus.
+ (rshift_significand, lshift_significand): Likewise.
+ (do_divide): Apply sticky bit after normalization.
+ (real_to_decimal, real_to_hexadecimal): Fix sign of Inf and NaN.
+
+2002-10-04 David Edelsohn <edelsohn@gnu.org>
+
+ * unroll.c (copy_loop_body): Remove REG_EQUAL note attached to
+ copied instruction if the note is not loop invariant.
+
But neither should have had any effects on SPECint. Anyway, I'll
start undoing patches as time permits.
Diego.
