Classes
struct Call
Describes the use of a value in a call instruction, specifying the call's target, the value's parameter number, and the possible range of offsets from the beginning of the value that are passed. More...
Public Attributes
uint64_t ParamNo = 0
ConstantRange Use {RangeWidth, true}
The range contains byte offsets from the parameter pointer which accessed by the function.
std::vector< Call > Calls
In the per-module summary, it summarizes the byte offset applied to each pointer parameter before passing to each corresponding callee.
Static Public Attributes
static constexpr uint32_t RangeWidth = 64

◆ ParamAccess() [2/2]

◆ Calls

std::vector<Call> llvm::FunctionSummary::ParamAccess::Calls

In the per-module summary, it summarizes the byte offset applied to each pointer parameter before passing to each corresponding callee.

In the combined summary, it's empty and information is propagated by inter-procedural analysis and applied to the Use field.

◆ ParamNo

uint64_t llvm::FunctionSummary::ParamAccess::ParamNo = 0

◆ RangeWidth

uint32_t llvm::FunctionSummary::ParamAccess::RangeWidth = 64 staticconstexpr

◆ Use

The range contains byte offsets from the parameter pointer which accessed by the function.

In the per-module summary, it only includes accesses made by the function instructions. In the combined summary, it also includes accesses by nested function calls.
