* Omnibus removal of register declarationsKarl Williamson2012-08-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes most register declarations in C code (and accompanying documentation) in the Perl core. Retained are those in the ext directory, Configure, and those that are associated with assembly language. See: http://stackoverflow.com/questions/314994/whats-a-good-example-of-register-variable-usage-in-c which says, in part: There is no good example of register usage when using modern compilers (read: last 10+ years) because it almost never does any good and can do some bad. When you use register, you are telling the compiler "I know how to optimize my code better than you do" which is almost never the case. One of three things can happen when you use register: The compiler ignores it, this is most likely. In this case the only harm is that you cannot take the address of the variable in the code. The compiler honors your request and as a result the code runs slower. The compiler honors your request and the code runs faster, this is the least likely scenario. Even if one compiler produces better code when you use register, there is no reason to believe another will do the same. If you have some critical code that the compiler is not optimizing well enough your best bet is probably to use assembler for that part anyway but of course do the appropriate profiling to verify the generated code is really a problem first.

We've already done this at least twice. (Yes, some of the assertions are after code that would already have SEGVd because it already deferences a pointer, but they are put in to make it easier to automate checking that each and every case is covered.) Add a tool, checkARGS_ASSERT.pl, to check that every case is covered. p4raw-id: //depot/perl@33291
