[Attributor] AAValueConstantRange: Value range analysis using constant range
Summary:
This patch introduces `AAValueConstantRange`, which answers a possible range for integer value in a specific program point.
One of the motivations is propagating existing `range` metadata. (I think we need to change the situation that `range` metadata cannot be put to Argument).
The state is a tuple of `ConstantRange` and it is initialized to (known, assumed) = ([-∞, +∞], empty).
Currently, AAValueConstantRange is created in `getAssumedConstant` method when `AAValueSimplify` returns `nullptr`(worst state).
Supported
- BinaryOperator(add, sub, ...)
- CmpInst(icmp eq, ...)
- !range metadata
`AAValueConstantRange` is not intended to extend to polyhedral range value analysis.

[Attributor] AAValueConstantRange: Value range analysis using constant range
Summary:
This patch introduces `AAValueConstantRange`, which answers a possible range for integer value in a specific program point.
One of the motivations is propagating existing `range` metadata. (I think we need to change the situation that `range` metadata cannot be put to Argument).
The state is a tuple of `ConstantRange` and it is initialized to (known, assumed) = ([-∞, +∞], empty).
Currently, AAValueConstantRange is created in `getAssumedConstant` method when `AAValueSimplify` returns `nullptr`(worst state).
Supported
- BinaryOperator(add, sub, ...)
- CmpInst(icmp eq, ...)
- !range metadata
`AAValueConstantRange` is not intended to extend to polyhedral range value analysis.

[Attributor] AAValueConstantRange: Value range analysis using constant range
Summary:
This patch introduces `AAValueConstantRange`, which answers a possible range for integer value in a specific program point.
One of the motivations is propagating existing `range` metadata. (I think we need to change the situation that `range` metadata cannot be put to Argument).
The state is a tuple of `ConstantRange` and it is initialized to (known, assumed) = ([-∞, +∞], empty).
Currently, AAValueConstantRange is created in `getAssumedConstant` method when `AAValueSimplify` returns `nullptr`(worst state).
Supported
- BinaryOperator(add, sub, ...)
- CmpInst(icmp eq, ...)
- !range metadata
`AAValueConstantRange` is not intended to extend to polyhedral range value analysis.

[Attributor] AAValueConstantRange: Value range analysis using constant range
Summary:
This patch introduces `AAValueConstantRange`, which answers a possible range for integer value in a specific program point.
One of the motivations is propagating existing `range` metadata. (I think we need to change the situation that `range` metadata cannot be put to Argument).
The state is a tuple of `ConstantRange` and it is initialized to (known, assumed) = ([-∞, +∞], empty).
Currently, AAValueConstantRange is created in `getAssumedConstant` method when `AAValueSimplify` returns `nullptr`(worst state).
Supported
- BinaryOperator(add, sub, ...)
- CmpInst(icmp eq, ...)
- !range metadata
`AAValueConstantRange` is not intended to extend to polyhedral range value analysis.

[Attributor] AAValueConstantRange: Value range analysis using constant range
Summary:
This patch introduces `AAValueConstantRange`, which answers a possible range for integer value in a specific program point.
One of the motivations is propagating existing `range` metadata. (I think we need to change the situation that `range` metadata cannot be put to Argument).
The state is a tuple of `ConstantRange` and it is initialized to (known, assumed) = ([-∞, +∞], empty).
Currently, AAValueConstantRange is created in `getAssumedConstant` method when `AAValueSimplify` returns `nullptr`(worst state).
Supported
- BinaryOperator(add, sub, ...)
- CmpInst(icmp eq, ...)
- !range metadata
`AAValueConstantRange` is not intended to extend to polyhedral range value analysis.
