+strictfp のために fscale 命令ではなく乗算 (fmul 命令) を使うようにした。

+
+マクロ CAUSE_STACKOVERFLOW と NULLEXC_BY_SIGNAL が define されている場合、
+これまで、NullPointerException が StackOverflowError だと解釈されてしまう
+可能性がわずかにあった。この判定を厳密に行うようにした。
+あらゆる FP 演算を強制的に strictfp にした状態で
+SPEC JVM98 の _209_db をデータサイズ 10 以上で実行して発覚。
+(signal.c)

+
+SSE2 に対応させた。
+configure --enable-sse2 とした場合、浮動小数点数の四則演算他に
+x87 命令ではなく SSE2 命令を使うようにした。
+SSE2 で行うようにした処理は次の通り:
+  - 四則演算
+    関係する内部命令を SSE2 命令に対応させた:
+      fadd, fsub, fmul, fdiv, dadd, dsub, dmul, ddiv および、
+      fld, fld4, fload_fld, faload_fld, dld, dld8, dload_dld, daload_dld,
+      fst, fst_fstore, fst_fastore, dst, dst_dstore, dst_dastore
+    また、SSE2 を使う場合は strictfp のための処理をコンパイルしないようにした。
+    strictfp の指定が一致した場合のみ inlining できる、という制約を外した。
+    fld, fst, dld, dst 系内部命令の SSE2 移行に伴い、f2d, d2f の処理も変更。
+  - 平方根 (Math#sqrt())
+  - 32bit 整数から FP への変換 (バイトコード命令 i2f, i2d)
+SSE2 への移行は保留した処理は次の通り:
+  - 64bit 整数からの変換 (バイトコード命令 l2f, l2d)
+    SSE2 だけでは厄介なので、x87 命令で処理。
+  - FP から整数への変換 (バイトコード命令 f2i, f2l, d2i, d2l)
+    面倒なので保留。
+  - FP の比較 (バイトコード命令 fcmpl, fcmpg, dcmpl, dcmpg)
+    面倒なので保留。
+
+バイトコード命令 fneg, dneg で浮動小数点数の符号を反転するために、
+x87 命令 fchs を使うのは止めた。
+xor 命令で直接最上位ビットを反転させるようにした。
+(code.c, compile.c)
+
+[20010625]
+
+configure に --enable-sse2 オプションを追加した。
+(configure.in, config.h.in)
