+
+signal handler で、SIGSEGV, SIGBUS だけでなく、
+除算 (idiv, irem, ldiv, lrem) で発生する SIGFPE も扱うようにした。
+0 除算で ArithmeticException を発生させ、
+MIN_VALUE / -1 で結果を MIN_VALUE に、MIN_VALUE % -1 で結果を 0 にする。
+ただし、long 型の MIN_VALUE [/%] -1 については
+ライブラリ関数が適切に扱うことを期待して何もしない。
+(compiler.c, compiler.h, compile.c, code.c, computil.c)
+
+従来のマクロ EXC_BY_SIGNAL を NULLEXC_BY_SIGNAL に変更し、
+ARITHEXC_BY_SIGNAL を新設。
+EXC_BY_SIGNAL はこの 2つの or とした。

+
+構造体 throwentry にメンバ opcode を追加、
+throwtableAdd() にて opcode も登録するようにした。
+(compiler.h, computil.c)
+
+ldiv, lrem のネイティブコードにて、
+%ebp レジスタをスタックに積んで保存するようにした。
+0 除算の際に signal handler が利用する。
+(code.c, compiler.c)

 [19990524]
 
 code.c のコンパイルフラグに -fno-omit-frame-pointer を追加。
