Subject: target/arm: Return correct IL bit in merge_syn_data_abort
|
|
|
|
Git-commit: 30d544839e278dc76017b9a42990c41e84a34377
|
|
|
|
The IL bit is set for 32-bit instructions, thus passing false
|
|
with the is_16bit parameter to syn_data_abort_with_iss() makes
|
|
a syn mask that always has the IL bit set.
|
|
|
|
Pass is_16bit as true to make the initial syn mask have IL=0,
|
|
so that the final IL value comes from or'ing template_syn.
