Why Static Const Almost Always Trumps Const

Finding the answer wanting, I changed the function that prompted me to raise the question in the first place. Examining the disassembly reminded me of a discovery that I made so long ago that I had forgotten the details that led me to almost always pairstaticandconstwhen I define arrays of constants, such as lookup tables and the like.

At first I thought this might be a compiler quirk, so I ran a couple of trivial examples through
gcc -s. That does substantially the same, so I'm guessing it's a language feature. One for the standards committee "lawyers".Software rusts. Simon Stephenson, ca 1994. So does this signature. me, 2012

Thanks much for duplicating the observation with the other popular C compiler. As I said, I observed the same thing about a dozen years ago, but I had forgotten the details. Anyway, so far as I know, the same holds whether your code is straight ANSI C or ANSI C++. The test case that I cited in the Stack Overflow article is straight ANSI C.
