Quotes About Compiler

According to Hansen, a real monitor should allow a compiler to verify that the code is correct and thus help to eliminate programming mistakes. However, Java simply uses something that looks like a monitor, but doesn't provide any of a monitor's benefits. The Java compiler knows almost nothing about synchronization.

At least for the people who send me mail about a new language that they're designing, the general advice is: do it to learn about how to write a compiler.

Before you start to look at the bug, make sure that you are working on code that built cleanly—without warnings. We routinely set compiler warning levels as high as possible. It doesn't make sense to waste time trying to find a problem that the computer could find for you! We need to concentrate on the harder problems at hand.

Thompson and Ritchie were among the first to realize that hardware and compiler technology had become good enough that an entire operating system could be written in C, and by 1978 the whole environment had been successfully ported to several machines of different types.

When a field is declared volatile, the compiler and runtime are put on notice that this variable is shared and that operations on it should not be reordered with other memory operations. Volatile variables are not cached in registers or in caches where they are hidden from other processors, so a read of a volatile variable always returns the most recent write by any thread.

In 1951, Grace Murray Hopper, a mathematician with the U.S. Navy's Bureau of Ordnance Naval Reserve, conceived of a program called a compiler, which translated a programmer's instructions into the strings of ones and zeroes, or machine language, that ultimately controlled the computer. In principle, compilers seemed just the thing to free programmers from the tyranny of hardware and the mind-numbing binary code. Hopper

Any good software engineer will tell you that a compiler and an interpreter are interchangeable.

Most demons are as dumb as a sackful of hammers. This does not mean they're safe to mess with, any more than a C++ compiler is "safe" in the hands of an enthusiastic computer science undergrad. Some people can mess up anything, and computational demonology adds a new and unwelcome meaning to terms like "memory leak" and "debugger." Now

String saying = str1 + str2 + str3 + str4 + str5;   the compiler implements this as: String saying = new StringBuffer().append(str1).append(str2).                                    append(str3).append(str4).                                    append(str5).toString();

The first phase of C was - really, it was two phases in short succession of, first, some language changes from B, really adding the type structure without too much change in the syntax, and doing the compiler. The second phase was slower; it all took place within a very few years, but it was a bit slower, so it seemed.

Thompson and Ritchie were among the first to realize that hardware and compiler technology had become good enough that an entire operating system could be written in C, and by 1978 the whole environment had been successfully ported to several machines of different types.

Just in case you still don't fully understand the need for a compiler, your source code is like the raw materials that your computer needs. The compiler is like a machine that converts those raw materials to a final product, a compiled program that the computer can understand.

the purpose of the finally block is to contain cleanup code that should always be executed, the compiler will flag an error if you place a return statement inside a finally block. An
