Match: Move saturation alu patterns into match-sat-alu.pd [NFC]
Saturation arithmetic patterns in match.pd are moved to a new file, ``match-sat-alu.pd``, for better organization.
Saturation arithmetic patterns from match.pd are moved into a new file named match-sat-alu.pd. This change improves the organization of the pattern matching code, especially as more saturation ALU patterns are expected to be added. This is a non-functional change.
In Details
The match.pd file contains pattern matching descriptions used by the compiler to optimize certain operations. This commit moves the saturation arithmetic patterns to a separate file, match-sat-alu.pd, to improve maintainability. Search terms: GCC match.pd saturation arithmetic.
For Context
Compilers use pattern matching to identify opportunities to replace code sequences with more efficient equivalents. Pattern matching descriptions are stored in .pd files. This change reorganizes the pattern matching descriptions for saturation arithmetic, which helps keep the compiler's code well-structured and easier to maintain.
