Abstract
An adaptation of the classic register allocation algorithm to the problem of array storage optimization in MATLAB is presented. The method involves the decomposition of an interference graph’s color classes using inferred type information. A key trait is the use of symbolic types, along with control flow, in performing the decomposition. On a benchmark suite spanning the published test suites of some recent research MATLAB compilers, our implementation produces savings in the average virtual memory size, with respect to code generated by a commercial MATLAB compiler, of between 51 % and 139 % in 6 out of 11 programs, and savings between 0.7 % and 47 % in the remaining. In absolute terms, this ranged from 123KB to over 9MB. Substantial improvements in other categories of memory, such as resident sets and dynamic data (stack plus heap), were also observed and are reported. Speedups in execution times of at least over an order of magnitude in 4 programs, of over 100 % in 4 of the remaining, and 10 % and over in the rest are also reported.
