12 years agoCache the hash value of the operands in the MDNode.
Benjamin Kramer [Wed, 11 Apr 2012 14:06:54 +0000 (14:06 +0000)]
Cache the hash value of the operands in the MDNode.

FoldingSet is implemented as a chained hash table. When there is a hash
collision during insertion, which is common as we fill the table until a
load factor of 2.0 is hit, we walk the chained elements, comparing every
operand with the new element's operands. This can be very expensive if the
MDNode has many operands.

We sacrifice a word of space in MDNode to cache the full hash value, reducing
compares on collision to a minimum. MDNode grows from 28 to 32 bytes + operands
on x86. On x86_64 the new bits fit nicely into existing padding, not growing
the struct at all.

1% and 2% for C++ code with clang -c -O0 -g.

Only check for PHI uses inside the current loop.

Hoisting a value that is used by a PHI in the loop will introduce a
copy because the live range is extended to cross the PHI.

The same applies to PHIs in exit blocks.

llvm-stress: stop abusing ConstantFP::get()

ConstantFP::get(Type*, double) is unreliably host-specific:
it can't handle a type like PPC128 on an x86 host. It even
has a comment to that effect: "This should only be used for
simple constant values like 2.0/1.0 etc, that are
known-valid both as host double and as the target format."

Instead, use APFloat. While we're at it, randomize the floating
point value more thoroughly; it was previously limited
to the range 0 to 2**19 - 1.

because the Name field in the Value class is a pointer to a StringMap entry, we
repurpose the Name field for an MDString. It stores the StringMap entry in the
