Subject: [PATCH 150/217] build: Fix '-Wall' and '-O2' warnings
|
|
|
2eb93d |
|
|
|
2eb93d |
Stop specifying '-Wall and '-O2' in cc_flags, and rely on the buildtype
|
|
|
2eb93d |
and warning_level options. Fixup the '-D_FORTIFY_SOURCE=2' option to
|
|
|
2eb93d |
optionally be enabled for optimizated builds rather then forcing -O2.
