Detailed Description

Base class for all callable instructions (InvokeInst and CallInst) Holds everything related to calling a function.

All call-like instructions are required to use a common operand layout:

Zero or more arguments to the call,
Zero or more operand bundles with zero or more operand inputs each bundle,
Zero or more subclass controlled operands
The called function.

This allows this base class to easily access the called function and the start of the arguments without knowing how many other operands a particular subclass requires. Note that accessing the end of the argument list isn't as cheap as most other operations on the base class.

◆ bundle_op_info_begin() [1/2]

bundle_op_iterator llvm::CallBase::bundle_op_info_begin ( )

inline

Return the start of the list of BundleOpInfo instances associated with this OperandBundleUser.

OperandBundleUser uses the descriptor area co-allocated with the host User to store some meta information about which operands are "normal" operands, and which ones belong to some operand bundle.

The layout of an operand bundle user is

     +-----------uint32_t End-------------------------------------+
     |                                                            |
     |  +--------uint32_t Begin--------------------+              |
     |  |                                          |              |
     ^  ^                                          v              v

|---—|---—|-—|-—|-—|-—|-—|------—|-—|------—|-—|--— | BOI0 | BOI1 | .. | DU | U0 | U1 | .. | BOI0_U0 | .. | BOI1_U0 | .. | Un |---—|---—|-—|-—|-—|-—|-—|------—|-—|------—|-—|--— v v ^ ^ | | | | | +-----—uint32_t Begin---------—+ | | | +--------—uint32_t End--------------------------—+

BOI0, BOI1 ... are descriptions of operand bundles in this User's use list. These descriptions are installed and managed by this class, and they're all instances of OperandBundleUser<T>::BundleOpInfo.

DU is an additional descriptor installed by User's 'operator new' to keep track of the 'BOI0 ... BOIN' co-allocation. OperandBundleUser does not access or modify DU in any way, it's an implementation detail private to User.

The regular Use& vector for the User starts at U0. The operand bundle uses are part of the Use& vector, just like normal uses. In the diagram above, the operand bundle uses start at BOI0_U0. Each instance of BundleOpInfo has information about a contiguous set of uses constituting an operand bundle, and the total set of operand bundle uses themselves form a contiguous set of uses (i.e. there are no gaps between uses corresponding to individual operand bundles).

This class does not know the location of the set of operand bundle uses within the use list – that is decided by the User using this class via the BeginIdx argument in populateBundleOperandInfos.

Currently operand bundle users with hung-off operands are not supported.

When there isn't many bundles, we do a simple linear search. Else fallback to a binary-search that use the fact that bundles usually have similar number of argument to get faster convergence.

We need a decimal number below and to prevent using floating point numbers we use an intergal value multiplied by this constant.
