Bug 26390 – Add strip-unsupported-flags function to flag-o-matic eutils

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Douglas Russell (RETIRED) 2003-08-11 03:05:54 UTC]

Not all flags are supported by all versions of gcc. When an ebuild changes
cflags it is possible flags won't be recognised by an older version of gcc. This
function tests all cflags against current gcc and strips unsupported flags.

This may also be useful outside of this eclass to allow cflags to be
automatically checked against current gcc, say in a CFLAG equivalent of the ufed
program.

Patch for flag-o-matic eclass adding strip-unsupported-flags

we already have `gcc2-flags` ... why not make a `gcc3-flags` and a wrapper 
function named `strip-incompat-flags` or whatever, like you have 

[Comment 3 Douglas Russell (RETIRED) 2003-08-11 05:26:19 UTC]

Well. I could do that, but I thought this was a good method as it does not rely on having a list of compatible flags and will work with all versions of gcc present and probably future without updating...

Sorry if I've misunderstood your thinking here.

nah, i assumed your function worked in a manner similar to the other function 
 
i like your implementation ;)
