Abstract (in Japanese) (See Japanese page) 
(in English) This article presents a method of accelerating regression test of compilers by merging programs in test suites. Testing of compilers needs a large amount of computation time, since test suites of compilers usually consist of a huge number of test programs. Especially, in the early stages of compiler development, acceleration of test is an important issue, for bug fixes and regression test are alternately repeated for many times. The proposed method attempts to merge test programs in the test suites into longer programs so as to reduce the time for file open/close. During the merging, conflicts among the names of global variables, functions, and "typedef" declarations, as well as header file inclusion and separate compilation, are carefully handled so that the semantics of the original programs are maintained. In an experiment where about 9,000 test programs in \textit{testgen} test suite were merged into 117 programs, computation time was reduced into 1/44.2 on Windows Cygwin and into 1/7.7 on Linux (Ubuntu) on 2.53GHz Core i5 with 2GB memory.
