From: karthikbalaguru on 11 Jan 2010 15:07 Hi, There are certain editors that highlight the syntax/color for datatypes/variables or comments etc. Similarly, Is there a tool for C language that could suggest an optimized/alternate programming logic for the function that is written ? The optimized/alternate logic can be suggested as soon as we finish coding for one function or it can be suggested as soon as the code is compiled/parsed by that tool. It will be even more helpful if that tool also provides the cycle counts, cache usage, cache misses and lines of code also. It would be better if that tool has an option to enable / disable this feature either through compile time or some other configurations. Any ideas ? Thx in advans, Karthik Balaguru

Seriously, I think this is impossible. What I can recommend to you are some good books, including (More) Programming Perls and Hacker's delight. Andreas

Optimizing compilers exist and by using similar techniques it should be possible to write a compiler that uses C as both the source and target language. How useful this would be is another question. The resulting code would need to be humanly readable if the tool would be of any use and the would probably place severe restrictions on the sorts of optimizations that can be done. I would be surprised if no work along these lines has been done. -scattered

There has been quite a bit of work done in compilers at the expression level to optimize algorithms and statements implementing functionally equivalent statements in the generated code. The problem in the bigger scale suggested by the op is the ability to recognize the larger overview of the programming objective at the scale of turning a bubble sort into a quick sort. At the statement level recognizing functionality is generally a simple task. At the function level this a significantly larger problem. The solution may be mostly hard work and processing cycles. A start may be to catalog common functions and implementations and create a significant tool to recognize these functions from source code extracting out key function parameters and then using these to select alternative implementations. As well as the data base of common functions a significant piece of expert system software would need to be written to extract knowledge out of the source. Do-able probably.

Metrics are available in many (especially embedded system) compilers as part of the listing and report files. Better compilers do a good job of instruction scheduling and cache management in their code generation. The issue is the larger one of function rewriting where the problem is larger and less work has been done looking for solutions. Regards, -- Walter Banks Byte Craft Limited http://www.bytecraft.com |
