US 2019/0377559 A1 · BUILD-TIME CODE SECTION-SPECIFIC COMPILER SELECTION

Abstract

Systems, methods, and computer-readable media are described for selecting, at build time, a respective compiler and/or a respective set of compiler options for each section of code to be compiled such that the compiler/compiler options selected for each code section are optimized for that code section with respect to one or more metrics. Abstract syntax tree (AST) analysis and semantic analysis may be performed at build time for each section of code to identify the compiler/compiler options that produce compiled object code for that code section that maximizes or minimizes a desired metric. The metric according to which compiler/compiler option optimization is performed may be any suitable metric including, without limitation, performance, binary size, security, reliability, scalability, and so forth.

Dependent claims

A computer-implemented method for compiling computer-executable code, the method comprising:

selecting a metric to be optimized in connection with compilation of a section of the computer-executable code;
compiling a plurality of test programs using each of a plurality of different compilers to obtain a plurality of compiled test programs;
calculating, for each of the plurality of compiled test programs, a respective value of the metric;
determining a particular test program of the plurality of test programs that is most similar to the section of the computer-executable code;
determining that the respective value of the metric is optimized for a particular compiled test program corresponding to the particular test program;
determining which compiler of the plurality of compilers was used to compile the particular compiled test program;
and
compiling the section of the computer-executable code using the determined compiler.
