Windows compilers comparison

Below are our results of the run-time benchmarks. The bit compiler variants were used, with the exception of the Lahey Fortran LF compiler formerly LF95 , which exists only as a bit compiler and is also listed here because of its wide distribution.

Furthermore, if not specified by the optimization level, loop unrolling was used. AP stands for AutoParallel, i. The benchmark programs were run several times, at least 10 times in a row, and the respective run-time was measured.

If the run-time measurements stabilized i. Hopefully that's the kind of information you were looking for! Community Bot 1 1 1 silver badge. MattyT MattyT 6, 2 2 gold badges 19 19 silver badges 16 16 bronze badges. Great list. I've observed every single one you mentioned. Regards Friedrich.

But what defines the "best"?

Time to compile code; Size of compiled code; Speed of compiled code; Memory usage of compiled code; Bugs and probability of seg faulting; Support; Community; etc.

Different things matter to different people. Improve this answer. Rik Rik Correctness is the sine qua non. I also like To have a compiler that runs really fast like lcc or ocamlc To have a compiler that produces really good code like ocamlopt or MLton It's OK if they are two different compilers.

This was prevalent during a period in such a way that many of the C compilers were based on it. The advantages of PCC depended on its capabilities and probability predictions. PCC compiler was made such that source files were machine-dependent, not all but only a few of them. It can detect syntax errors and can perform perfect validity checks. A new version of PCC was released on 10 December This supports many programming languages and it is a free software foundation under the General Public License.

This compiler was first released in and it supported only C- Programming language during the start. Here, each of the different language compilers has its own program that reads the code written and sends the machine code as the output. All of these have a common internal structure. When a high-level language is written, as per the language it is written, the compiler parses the code in that language and produces an abstract syntax tree.

Coming to the optimization part, as already known this can occur during any phase of the compilation. However, here the bulk optimizations are performed before the code generation and after the syntax, semantic analysis.

Below are a few of the optimizations performed by GCC.
