The article discusses the issue of compiler optimizations based on undefined behavior in C programming language and argues that such practices can lead to worse code quality, security vulnerabilities, and performance issues for non-benchmark programs. It advocates for a focus on source-level optimizations instead.
Optimizations based on undefined behavior can lead to worse code quality, security vulnerabilities, and performance issues for non-benchmark programs in the software industry.
- C compilers often optimize code based on assumptions about undefined behavior, which can lead to worse code quality
- Source-level optimizations provide better performance than compiler optimizations for non-benchmark programs
- Undefined behavior is widespread in production code and removing it requires significant effort
- Focus should be shifted from 'optimizations' to optimization⋆ (source-level optimizations) for better program performance
Quality:
The article presents a balanced view with both technical arguments and practical examples.
Discussion (13):
2 min
The comment thread discusses the role of undefined behavior in C compilers and its implications for programmers, with a focus on the power dynamics within the C programming community. The main arguments revolve around the extent to which undefined behavior should influence compiler optimizations and strategies for improving predictability in C.
- Undefined behavior constructs should not grant compiler writers complete freedom
- The power structure in the C programming community favors implementers over programmers
Counterarguments:
- C programmers want compilers to behave one way, implementers want them to behave another
- Power structure is what it is: C implementers write the standard and implement compilers
- Switching to a different language with defined semantics might be an option for C programmers
