Fields§
§instance: Instance<'tcx>
§mir: &'tcx Body<'tcx>
§debug_context: Option<FunctionDebugContext<'tcx, Bx::DIScope, Bx::DILocation>>
§llfn: Bx::Function
§cx: &'a Bx::CodegenCx
§fn_abi: &'tcx FnAbi<'tcx, Ty<'tcx>>
§personality_slot: Option<PlaceRef<'tcx, Bx::Value>>
When unwinding is initiated, we have to store this personality value somewhere so that we can load it and re-use it in the resume instruction. The personality is (afaik) some kind of value used for C++ unwinding, which must filter by type: we don’t really care about it very much. Anyway, this value contains an alloca into which the personality is stored and then later loaded when generating the DIVERGE_BLOCK.
cached_llbbs: IndexVec<BasicBlock, CachedLlbb<Bx::BasicBlock>>
A backend BasicBlock
for each MIR BasicBlock
, created lazily
as-needed (e.g. RPO reaching it or another block branching to it).
cleanup_kinds: Option<IndexVec<BasicBlock, CleanupKind>>
The funclet status of each basic block
funclets: IndexVec<BasicBlock, Option<Bx::Funclet>>
When targeting MSVC, this stores the cleanup info for each funclet BB.
This is initialized at the same time as the landing_pads
entry for the
funclets’ head block, i.e. when needed by an unwind / cleanup_ret
edge.
landing_pads: IndexVec<BasicBlock, Option<Bx::BasicBlock>>
This stores the cached landing/cleanup pad block for a given BB.
unreachable_block: Option<Bx::BasicBlock>
Cached unreachable block
terminate_block: Option<(Bx::BasicBlock, UnwindTerminateReason)>
Cached terminate upon unwinding block and its reason
locals: Locals<'tcx, Bx::Value>
The location where each MIR arg/var/tmp/ret is stored. This is
usually an PlaceRef
representing an alloca, but not always:
sometimes we can skip the alloca and just store the value
directly using an OperandRef
, which makes for tighter LLVM
IR. The conditions for using an OperandRef
are as follows:
- the type of the local must be judged “immediate” by
is_llvm_immediate
- the operand must never be referenced indirectly
- we should not take its address using the
&
operator - nor should it appear in a place path like
tmp.a
- we should not take its address using the
- the operand must be defined by an rvalue that can generate immediate values
Avoiding allocs can also be important for certain intrinsics,
notably expect
.
per_local_var_debug_info: Option<IndexVec<Local, Vec<PerLocalVarDebugInfo<'tcx, Bx::DIVariable>>>>
All VarDebugInfo
from the MIR body, partitioned by Local
.
This is None
if no variable debuginfo/names are needed.
caller_location: Option<OperandRef<'tcx, Bx::Value>>
Caller location propagated if this function has #[track_caller]
.

that the given constant
is an Const::Unevaluated
and must be convertible to
a ValTree

on zulip.
Note that this function is cursed, since usually MIR consts should not be evaluated to valtrees!
