◆ LLVMExtractFirstVectorElement()
| llvm::Value* LLVMExtractFirstVectorElement | ( | llvm::Value * | v | ) |
Given a vector-typed value, this function returns the value of its first element. Rather than just doing the straightforward thing of using a single extractelement instruction to do this, this function tries to rewrite the computation for the first element in scalar form; this is generally more efficient than computing the entire vector's worth of values just to extract the first element, in cases where only the first element's value is needed.

◆ LLVMExtractVectorInts()
| bool LLVMExtractVectorInts | ( | llvm::Value * | v, |
| int64_t | ret[], | ||
| int * | nElts | ||
| ) |
Given a vector-typed value v, if the vector is a vector with constant element values, this function extracts those element values into the ret[] array and returns the number of elements (i.e. the vector type's width) in *nElts. It returns true if successful and false if the given vector is not in fact a vector of constants.

References Assert, and lVectorValuesAllEqual().
Referenced by lAllDivBaseEqual(), lCheckAndForLinear(), lExtractConstOffsets(), lVectorIs32BitInts(), and lVectorShiftRightAllEqual().
◆ LLVMFlattenInsertChain()
| llvm::Value* LLVMFlattenInsertChain | ( | llvm::Value * | inst, |
| int | vectorWidth, | ||
| bool | compare = true, |
||
| bool | undef = true, |
||
| bool | searchFirstUndef = false |
||
| ) |
This function takes chains of InsertElement instructions along the lines of:
v0 = insertelement undef, value_0, i32 index_0 v1 = insertelement v1, value_1, i32 index_1 ... vn = insertelement vn-1, value_n-1, i32 index_n-1
and initializes the provided elements array such that the i'th llvm::Value * in the array is the element that was inserted into the i'th element of the vector.
When the chain of insertelement instruction comes to an end, the only base case that this function handles is the initial value being a constant vector. For anything more complex (e.g. some other arbitrary value, it doesn't try to extract element values into the returned array.
This also handles one of two common broadcast patterns:
- broadcast_init.0 = insertelement <4 x i32> undef, i32 val, i32 0 broadcast.1 = shufflevector <4 x i32> smear.0, <4 x i32> undef, <4 x i32> zeroinitializer
- gep_ptr2int_broadcast_init = insertelement <8 x i64> undef, i64 gep_ptr2int, i32 0 %0 = add <8 x i64> gep_ptr2int_broadcast_init, <i64 4, i64 undef, i64 undef, i64 undef, i64 undef, i64 undef, i64 undef, i64 undef> gep_offset = shufflevector <8 x i64> %0, <8 x i64> undef, <8 x i32> zeroinitializer Function returns: Compare all elements and return one of them if all are equal, otherwise NULL. If searchFirstUndef argument is true, look for the vector with the first not-undef element, like: <i64 4, i64 undef, i64 undef, i64 undef, i64 undef, i64 undef, i64 undef, i64 undef> If compare argument is false, don't do compare and return first element instead. If undef argument is true, ignore undef elements (but all undef yields NULL anyway).

◆ LLVMUInt8Vector() [2/2]
| llvm::Constant* LLVMUInt8Vector | ( | const uint8_t * | i | ) |
Returns an LLVM i8 vector based on the given array of values. The array should have g->target.vectorWidth elements.

◆ LLVMUIntAsType()
| llvm::Constant* LLVMUIntAsType | ( | uint64_t | , |
| llvm::Type * | t | ||
| ) |
Returns a constant integer or vector (according to the given type) of the given unsigned integer value.

◆ LLVMVectorIsLinear()
| bool LLVMVectorIsLinear | ( | llvm::Value * | v, |
| int | stride | ||
| ) |
Given vector of integer-typed values, this function returns true if it can determine that the elements of the vector have a step of 'stride' between their values and false otherwise. This function tries to handle as many possibilities as possible, including things like all elements equal to some non-constant value plus an integer offset, etc. Needless to say (the halting problem and all that), it may return false for some vectors that are in fact linear.

◆ LLVMVectorValuesAllEqual()
| bool LLVMVectorValuesAllEqual | ( | llvm::Value * | v, |
| llvm::Value ** | splat | ||
| ) |
Tests to see if all of the elements of the vector in the 'v' parameter are equal. Like lValuesAreEqual(), this is a conservative test and may return false for arrays where the values are actually all equal.
