Subject: [Qemu-devel] Should configure --enable-debug add -Og to CFLAGS?
Date: Thu, 27 Jun 2019 17:43:30 +0200 [thread overview]
Message-ID: <87tvcbc9ul.fsf@dusky.pond.sub.org> (raw)
The fine manual advises:
'-O0'
Reduce compilation time and make debugging produce the expected
results. This is the default.
[...]
'-Og'
Optimize debugging experience. '-Og' should be the optimization
level of choice for the standard edit-compile-debug cycle, offering
a reasonable level of optimization while maintaining fast
compilation and a good debugging experience. It is a better choice
than '-O0' for producing debuggable code because some compiler
passes that collect debug information are disabled at '-O0'.
Our configure --enable-debug effectively picks -O0. Should it pick -Og
instead?
