#168274 - you "understand well enough"
Responding to: ???'s previous message
R:So far, it's been much easier to use ASM, specifically a macroassembler, with my library of macros, which I understand well enough to equal the comparable intrinsics of any compiler, and, as a result, I know the generated code is as fast and as dense as I require.
E:Finally the cat came out of the bag
R:As for the cat ... I have no idea what you mean
you "understand well enough" the above and do not, and have no intention of getting to "understand well enough" C etc.

Yes, I know what my macros do, how much code they contribute, how much time they require, and, since that's the case, and I already have them on hand, there's no need for a compiler.
That may be so, but why do you then argue with those that do have a need for a compiler

I'd take a look at a compiler if there were a reasonable way to evaluate it. That doesn't guarantee I'd buy it, though. It would have to be advantageous in some meaningful way for me to buy one.

T.T.T. and you do not want to. If it (as it did for me) takes a long time to get "up to speed" in C before the advantages shine, then, of course it is easy for you to just say "this is not worth it"

I'd take a look at a compiler if there were a reasonable way to evaluate it. The snake bites its tail here, if you are not fluent in C (i.e. have worked for years with 'some' compiler) you can not evaluate. Another issue here is that 'getting fluent' in C is almost impossible on a micro, it is many times faster on a PC, which is why I always recommend learning C (using Kochans book) on a PC before even writing the first C line for a micro.

               So ... Why do you do all that?            01/01/70 00:00      
                  wrong choice of word            01/01/70 00:00      
                     It's just a millstone ...            01/01/70 00:00      
                  re: why?            01/01/70 00:00      
      My computer _boots_ faster than that.            01/01/70 00:00      
         DMA?            01/01/70 00:00      
      Maybe it's the amount of memory            01/01/70 00:00

               Isn't 4k plenty for a '51?            01/01/70 00:00      
                  which '51 does have that?            01/01/70 00:00      
                     Erik would call those "deviates".            01/01/70 00:00

                           It's also pipelined.            01/01/70 00:00      
                              then it's irrelevant            01/01/70 00:00      
                  If you can ignore those features            01/01/70 00:00      
               keeping up            01/01/70 00:00      
                  I feel your pain ...            01/01/70 00:00      
                     Don't see problems - see possibilities            01/01/70 00:00      
                        Do you really want to hide from reality?            01/01/70 00:00      
                           Always hiding behind excuses            01/01/70 00:00      
                              What excuses?            01/01/70 00:00      
                                 Your excuses            01/01/70 00:00      
                                    Do you directly or indirectly work for Keil?            01/01/70 00:00      
                                       BULL!!            01/01/70 00:00      
                                          I don't harbor any animosity, but I don't like being lied-to            01/01/70 00:00      
                                             you "understand well enough"            01/01/70 00:00      
                                                I have to agree ... evaluation takes time ...            01/01/70 00:00      
                                                   this is where I think I'm the realist            01/01/70 00:00      
                                                      If only the pieces were separately available ...            01/01/70 00:00      
                                                         I can't and would never            01/01/70 00:00      
                                                            So ... Who's a simulator specialist?            01/01/70 00:00      
                                                               don't know, don't care            01/01/70 00:00      
                                                                  So why even mention it?            01/01/70 00:00      
                                                                     because someone (you?) brought it up            01/01/70 00:00      
                                       Tangential Richard at work            01/01/70 00:00      
                           the pot calling the kettle black            01/01/70 00:00      
                     that's the crux            01/01/70 00:00      
                        It's a matter of realism            01/01/70 00:00      
                           well, if you do not have the time to evaluate, your points            01/01/70 00:00      
                              I have to disagree ...            01/01/70 00:00      
                                 no need            01/01/70 00:00      
                                    That would be an ideal fix!            01/01/70 00:00      
                  no way            01/01/70 00:00      
                     but only if we both define a project            01/01/70 00:00      
                        oh, that's no proof then...            01/01/70 00:00      
                           It would be a nice idea, but how would you time it?            01/01/70 00:00      
                           you did not read what I said            01/01/70 00:00      
                              implication and how to challenge it            01/01/70 00:00      
                                 disassembly            01/01/70 00:00      
                                    Encryption module?            01/01/70 00:00      
                                    not at all            01/01/70 00:00      
                                       It's clear to see that some folks really like 'C'            01/01/70 00:00      
                                          can you only like one thing?            01/01/70 00:00      
                                             Yes, but ...            01/01/70 00:00      
                                                you can boil steak too            01/01/70 00:00      
                                                   but you don't have to do that            01/01/70 00:00      
                                                      but you just said            01/01/70 00:00      
                                       no praise, just not hate            01/01/70 00:00      
                                          That makes sense            01/01/70 00:00      
                                          not that claim            01/01/70 00:00      
                                             again you miss 'usually', 'mostly', 'often', etc            01/01/70 00:00      
                                                Not so ... exactly            01/01/70 00:00      
                                                   Based on what experience?            01/01/70 00:00      
                                                      That's not how it works            01/01/70 00:00      
                                                         maintenance is a totally different issue            01/01/70 00:00      
                                                         apples to pears?            01/01/70 00:00      
                                                            I don't need to compare/contrast apples and pears            01/01/70 00:00      
                                                               The embedded world is larger than your tiny island            01/01/70 00:00      
                                                   IF            01/01/70 00:00      
                                                      It's all about initial hardware cost, not maintenance cost.            01/01/70 00:00      
                                                         Value of investment            01/01/70 00:00

                                                         Whose business?            01/01/70 00:00      
                                                            What do you mean by "code analysis tools"?            01/01/70 00:00      
                                                               Some important tests            01/01/70 00:00      
                                                                  Yes, those come up in HLL, but ...            01/01/70 00:00      
                                                                     Memory leaks nothing to do with HLL            01/01/70 00:00      
                                                                        Yeah, you can do that ... but it's not recommended            01/01/70 00:00      
                                                                           More way than one to create memory leaks            01/01/70 00:00      
                                                                           that is not applicable to small embedded            01/01/70 00:00

                                                                     MISRA and assembly don't mix well.            01/01/70 00:00
