I never wrote set -e is bashism. I implied that people who use set -e will also write bashisms. Goodness knows I've had to fix enough of such garbage over the years to work with Solaris' /bin/sh and I'm revolted, si

M4 is a generic preprocessor, not a backend shell program compiler. And I'm not your bro.

You mean the same thing as the Linux / Docker / bash echo chamber on this site? Hm. Seems the good folk don't like a dose of their own medicine.

I am kicking the hornets' nest because IT is in a really bad shape because of the GNU/Linux monoculture and I want for things not only to change, but to effect change. GNU/Linux got to where it is by users bitching about how

The discussion was just fine until someone suggested set -e claiming that || exit 1 is "harder to understand" and "ugly".

by Annatar 7y ago
Please take a moment to pause and consider what you're writing. Someone here wrote "let the backend generate correct code". I responded that people usually write shell programs, not backends.
278.
by Annatar 7y ago
How is || exit 1 harder to understand? With the exception of GNU autotools, I know of no backends which would emit shell programs. People write programs in shells.

Which part of the fact that Linux is a toy bothers you, and why does it bother you? Is Linux a religion for you?

I remember that. That was emulation and it was not usable the way a 75 MHz Z80 could be, running code directly on the CPU (even if it is an FPGA).

It doesn't matter what people think, what matters is that the code is portable. Isn't it better that the program JustWork(SM) unmodified on all platforms without having to worry about whether the shell is POSIX-compliant? Up until

by Annatar 7y ago
This will make the program instantly unportable, because not all Bourne shells are POSIX-compliant. Please don't do that. || exit 1 is portable.

I never was a fan of the Zilog Z80 (its instruction set reminded me too much of the idiotic intel 80x86 family), but seeing someone running the Control Program for Microcomputers on a whopping 25 MHz Z80 is incredibly cool... just imagine w

Leon is a 32-bit, SPARC V8 ISA implementation. It's also one of the rare radiation-hardened designs (for use in space equipment where cosmic radiation has a significant influence on correctness of operation). An OpenSPARC T2 is a SPARC

"(a) nop doesn't prefetch;" I wrote nopsw and you are writing about nop. Are you doing this on purpose? nop doesn't, but only on intel family of processors , nopsw has a side-effect of prefetching. "Yes, that'

This is awesome!!! (Ultra)SPARC CPU's are a joy to code for in assembler, and modern T3, T4 and T5's are number crunching monsters. How about synthesizing the GPL-licensed OpenSPARC T2 now? https://www.oracle.com/t

"A human would turn the for loop that counts up into a do-while loop that counts down?" Of course an experienced coder would do that; that's the entire point of why a compiler will never be able to generate as short and as fa

This is how a human would code the same (a human would know, for instance, that (s)he wants to multiply 50 times, passing that in %rax (that would be your "n" in C), something a compiler can never know, which is one of many rea

No sorry, but that's incorrect. I saw the bug requests myself when the database was still accessible, and I read multiple accounts from engineers working on performance improvements at Sun Microsystems , who I trust far more than anec

Considering I wrote above exactly what to do (gcc -S), I believe you are not making this request in good faith; rather, you seek to test whether I know what I'm writing about. However, had you done what I told you to do, you wouldn&#x2

No, the remote does not need new batteries; Linux is slow. There is an unfinished port of illumos to ARM. Solaris was traditionally used for embedded applications (such as flight control systems in airplanes) and it is ideal for embedded ap

What is true is that nobody is that any more thanks to low skilled Linux labor. Thanks, GNU! Thanks, Linux!

Neither is true. Well, the first might be true for you in your mind, but doesn't change the fact that C is a high level language modelling an abstract system, and providing that model through its standard libraries (which is what makes

C is a high level language with capability of low level access: we regularly made fun of C programmers in high school (like my math teacher) because they didn't know how to code in assembler and had to write abstract high level code in

And the really funny part for us C practitioners is, we know we'll rarely be as fast as machine code generated from Fortran.

C-like performance is required more than ever: we have to have monster multicore machines with gigabytes of memory just to run any software. That's absolutely ridiculous.
