| Subject: [PATCH] compiler.m4: do not remove -g flag |
| |
| A sed expression such as 's/-g//' not only removes the -g |
| debugging-related flag, but also turns more specific flags such as |
| -mfloat-gprs=double into -mfloatprs=double, which is no longer a valid |
| flag. |
| |
| However, it turns out that removing -g is not necessary: having -g0 |
| after -g negates the -g, and having -ggdb after -g is enough to produce |
| debugging information for GDB. |
