| Class | Description |
|---|---|
| CallingConvention |
This class contains IA32 calling conventions
The two public methods are:
expandCallingConventions(IR) which is called by the
register allocator immediately before allocation to make manifest the
use of registers by the calling convention.
|
| ExpandFPRStackConvention |
At the beginning of each basic block, the register allocator expects
all floating-point stack locations to be available, and named
FPi, 0 < i < 7
However, BURS may consume FP stack locations by inserting instructions
that push or pop the floating-point stack.
|
| MIRSplitRanges |
This class splits live ranges for certain special cases to ensure
correctness during IA32 register allocation.
|
| PhysicalRegisterConstants |
This class holds constants that describe IA32 physical register set.
|
| RegisterPreferences | |
| RegisterRestrictions |
An instance of this class encapsulates restrictions on register
assignment.
|
| RewriteMemoryOperandsWithOversizedDisplacements |
Processes memory operands with a displacement that doesn't fit
into 32 bits.
|
| StackManager |
Class to manage the allocation of the "compiler-specific" portion of
the stackframe.
