Subject: [PATCH] cgcc: check sparse options fmax-errors and fmax-warnings
Date: Tue, 3 Sep 2024 08:12:57 +0200 [thread overview]
Message-ID: <20240903061257.648402-1-dmitrii.golovanov@intel.com> (raw)
Recognize sparse command-line options `-fmax-errors` and `-fmax-warnings`
as "check" options:
`-fmax-warnings` - dont pass it to CC neither with integer value,
nor as 'unlimited'.
`-fmax-errors` - only as 'unlimited' value to avoid 'unrecognized
command-line option' GCC error which also accepts it as numeric.
