|
Replace a temporary node with a permanent one. |
|
Replace a temporary node with a uniqued one. |
|

Description |
Lookup or compute a mapping for a piece of metadata. |
|
Version of MapMetadata with type safety for MDNode. |
|
If the given TBAA tag uses the scalar TBAA format, create a new node corresponding to the upgrade to the struct‐path aware TBAA format. Otherwise return the |

Compute known bits from the range metadata. |
|
Extract branch weights from MD_prof metadata |
|
Faster version of extractBranchWeights() that skips checks and must only be called with "branch_weights" metadata nodes. Supports uint32_t. |
|
Faster version of extractBranchWeights() that skips checks and must only be called with "branch_weights" metadata nodes. Supports uint64_t. |
|
Retrieve the total of all weights from MD_prof data. |
|
Find and return the loop attribute node for the attribute |

|
Find subprogram that is enclosing this scope. |
|
Check if Branch Weight Metadata has an "expected" field from an llvm.expect* intrinsic |
|
Checks if an MDNode contains Branch Weight Metadata |
|
Return whether an MDNode might represent an access group. |
|
Checks if an MDNode contains value profiling Metadata |
|
Create a new loop identifier for a loop created from a loop transformation. |
|
Compute the union of two access‐group lists. |
|
Upgrade the loop attachment metadata node. |
|
Returns the allocation type from an MIB metadata node. |
|
