- Subject: RFA: Patch: Change FRV 'mdrotli' instruction to accept a signedimmediate
Hi Dave,
Any objections to my applying the patch below ? It changes the
mdrotli instruction for the FRV port so that it accepts a signed
immediate value instead of an unsigned one. According to Fujitsu
this is the correct behaviour. (See Issue #23199 for more
details). I could not find an FRV ISA anywhere on the web to
confirm this, but I assume that they are correct.
Cheers
Nick
