"guarantee" seems rather strong given the various known issues with (lack of) Annex F support in GCC. Do you have any actual configuration in mind it would affect, MIPS-specific or otherwise? For non-architecture-specific things, -std= options for C standards conformance are meant to enable whatever options are required (e.g. they disable the default -ffp-contract=fast), without affecting things not required by the standards by default (so they don't enable -frounding-math or -fsignaling-nans, for example). -- Joseph S.
