Add optimization flags for internal lapack #45

Closed nakatamaho closed 2 years ago

nakatamaho commented 2 years ago

Add optimization flags for internal lapack. Currently, we compile with the -O0 flag. To take benchmarks as the reference LAPACK, we should add some flags.

We reduced the optimization flag on mingw64.

Since LAPACK tests dump core as follows. make[5]: Leaving directory '/home/docker/mplapack/external/lapack/work/internal/lapack-3.9.1/TESTING/LIN' Testing COMPLEX16 LAPACK linear equation routines wine64 ./LIN/xlintstz.exe < ztest.in > ztest.out 2>&1 make[4]: *** [Makefile:179: ztest.out] Error 253 make[4]: Leaving directory '/home/docker/mplapack/external/lapack/work/internal/lapack-3.9.1/TESTING'
