The dante configure script has some logic to remove the -g flag from CFLAGS, but this logic is flawed and also removed -g in -mfloat-gprs=double, turning it into the invalid -mfloatprs=double, causing a build failure. This commit adds a patch that gets rid of this -g removal logic, since it is in fact unnecessary.

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.
