Series [PULL,01/25] target/arm: Allow setting the FPCR.EBF bit for FEAT_EBF16 | expand

Commit Message

Peter Maydell Sept. 5, 2024, 1 p.m. UTC 
To implement the FEAT_EBF16 semantics, we are going to need
the CPUARMState env pointer in every helper function which calls
bfdotadd().

Pass the env pointer through from generated code to the sme_bfmopa
helper. (We'll add the code that uses it when we've adjusted
all the helpers to have access to the env pointer.)
