openblas strips off -O1-O3 for certain source files, but forgets to handle -Os, -Og and -O. This means that the intended effect of 'no optimization' is not always reached. Signed-off-by: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

Subject: [PATCH] Makefile: also consider -O, -Og and -Os when stripping flags
|
|
|
|
gcc also supports -O, -Og and -Os as optimization flags.
|
|
They may be given on the make command-line by users.
|
|
|
|
For the calculation of LAPACK_NOOPT, all such flags should be considered.
