摘要： Disclosed is a compiler apparatus for generating an instruction code composed of instruction sets each including an instruction that designates an m-bit immediate value indicating a location of a data item in a memory area. The compiler apparatus sequentially selects, based on one data attribute, a data item from a group X composed of a plurality of data items; and judges, each time a data item is selected, whether the selected data item is allocatable to an n-byte memory area (n≦2m). When the judgment is negative, the compiler apparatus specifies, based on a different data attribute, a data item out of all the selected data items and excludes the specified data item from the group X, and repeats the selection until all the data items remaining in the group X after excluding specified data items are judged to be allocatable to the memory area.

摘要： The first, second, and third operating units 441 to 443 each perform a predetermined operation according to an instruction before a point of time partway through a clock cycle. When having performed a comparison operation, each operating unit outputs a result value to the condition flag operating unit 51. The condition flag operating unit 51 calculates a new condition flag value by performing a logical operation on either (a) a value that has been read from the condition flag register 46 and the result value or (b) the result values themselves. The condition flag operating unit 51 outputs, before the clock cycle ends, the new condition flag value to one of the first, second, and third gates 451 to 453 that is related to a conditional instruction so as to control nullification of the conditional new condition flag value.
摘要翻译：第一，第二和第三操作单元441至443各自根据在时钟周期的中途的时间点之前的指令执行预定的操作。当执行比较操作时，每个操作单元将结果值输出到条件标志操作单元51。条件标志操作单元51通过对（a）从条件标志寄存器46读取的值和结果值或（b）结果值本身执行逻辑运算来计算新条件标志值。条件标志操作单元51在时钟周期结束之前将新条件标志值输出到与条件指令相关的第一，第二和第三门451至453中的一个，以便控制条件新条件的无效标志值。

摘要： A compiling unit (110) generates indefinite branch information showing that an instruction set to be selected is indefinite, instead of generating a branch instruction. A linking unit (130) generates an appropriate direct addressing branch instruction by judging whether an instruction set used at a branch source and an instruction set used at a branch destination are the same. Also, one reference instruction set is determined. The compiling unit (110) adds a mode adjusting instruction that belongs to the reference instruction set and that is for causing a branch to an instruction placed at a branch destination and for selecting the instruction set that is originally to be selected. The mode adjusting instruction provides an alternative branch destination corresponding to an original branch destination, and the compiling unit (110) generates an indirect addressing branch instruction for causing a branch to the alternative branch destination and for selecting the reference instruction set.
