The Fortran language had been developed at IBM, but suffered from slow and error-prone three-stage batch processing workflow. [1] In the first stage, the compiler started with source code and produced object code. In the second stage, a linker constructed a complete program using growing libraries of common functions. Finally, the program was ...
This is one of the values of such a compiler: while it is straightforward to code the simple cases of this optimization, keeping all the details correct as the code is replicated and transformed is an error-prone process. The above loop will only achieve 80% of peak flops on the example system when blocked for the 16KB L1 cache size.
While it is possible to write programs directly in machine code, managing individual bits and calculating numerical addresses is tedious and error-prone. Therefore, programs are rarely written directly in machine code. However, an existing machine code program may be edited if the assembly source code is not available.
Example of an internal compiler error: somefile.c:1001: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if ...
provide high-level array operations that liberate programming from tedious and error-prone specifications of starts, stops and strides for array traversals thereby improving code reusability and programming productivity, in general.
CUPERTINO, Calif. (AP) — Apple is suspending an error-prone feature that used artificial intelligence to deliver bogus news alerts to some iPhone owners. The decision was disclosed Thursday as part of a test version for the next software release, iOS 18.3.
This automated much of the error-prone programming of batching/unbatching of records and controls of simultaneous read/write operations and end-of-file conditions. A COBOL compiler. This was very rarely used, early experiences not having been entirely favourable.
Around 20% of a project's routines contribute to 80% of the development costs. A classic study by IBM found that few error-prone routines of OS/360 were the most expensive entities. They had around 50 defects per 1000 lines of code and fixing them costs 10 times what it took to develop the whole system. [18]
