In Germany, there's no requirement for a written employment contract. The contract is formed implicitly if the employee keeps showing up for work, and the employer keeps paying them. Most employers use written contracts to override som

Oh, interesting. It's the & type in the CLI (I.12.1.1.2 in ECMA-335). It makes Java's GCs quite Java-specific in practice because there aren't that languages that even moderately widely used which are both statically type

If machine code is generated on (or close to) deployment, the implementation can choose a suitable collector. Hopefully, the proposed protocol will not require that implementations somehow optimize away interior object pointers for language

Go has interior pointers. All byte arrays support word-sized pointers to any of their array elements. I think that's somewhat unusual for a language implementation with a precise garbage collector. Usually, pointers always point to the

Go has exceptions, with the usual stack unwinding. The standard library does not use them (for the most part, panics are sometimes used to simplify error handling code, see encoding/gob). It's like Perl and Rust in this regard. Un

It's possible to use a lookup table (sort of) in a register. With x86-64-v2 and later, the code is larger, but potentially faster due to the shorter dependency chain: int div7 (int x) { return 9 - __builtin_popcountll (0x408102040810

I think IRIS² is actually an extension of the EU's GOVSATCOM initiative: https://defence-industry-space.ec.europa.eu/eu-space-policy/... This means it's for government use, and is not really comparable to com

Except … for spewing out fortune responses, most of your cost by far will be in bandwidth charges. Those won't change with the implementation language. If anything, the C++ version will just be able to burn your dollars faster. (Yes, I

The shift to Linux happened around the same time, and few people would bother with anything else but GCC. It might have might made a difference if the Gelato Federation had arrived earlier, with more funding, and a mandate to conduct generi

The timing is a bit unexpected, given that there was a similar discussion not too long ago, and I think someone stepped up as a quasi-maintainer (maybe even Adrian, who now acked the removal patch). Itanium will be remember for quite a whil

They could just produce tar output and compress that using system gzip. The “git archive” tool supports many output formats.

It's funny how this moves in circles: Automatic merging into hugepages (THP) is added to the kernel. Some workloads suffer, so it gets turned off again in some distributions (not all of course). But for many different workloads (some s

Do you cross-compile from aarch64 or to aarch64? I tend to treat the desire to cross-compile as a rather strong indicator that the architecture is just not viable for general-purpose computing. Either because it's impossible to get act

Doesn't this require support for deferrable constraints? Even if they are supported on the transaction level, once you have these kinds of dependency loops, they tend to impact lots and lots of things—restoring from backups, applicatio

I don't think the BMJ or other parts of the feral government have in-sourced the editorial process. Historically, juris claimed copyright-like protection for the consolidated text, as can be seen here: https://web.archive.or

Reading [1], is it really true under Irish law that as long as you are walking on one side of the fence (I'm not sure if “correct” is the best word to use here, given that it's clearly the dangerous side), you are not trespassing?

I think for x86-64, the 32-bit immediate operands totally qualify as CISC-style because they contribute to the variable length nature of the instruction encoding. And GCC uses them all the time, of course. GCC has a surprising tendency to u

Inlining heuristics used for -O3 are architecture-specific, so this just shows that things have been tuned in a particular way, probably based on the most prevalent icache sizes. -O2 numbers might be different because of reduced inlining. I

ICC has an option that is documented as: auto-p32 Instructs the compiler to analyze the program to determine if there are 64-bit pointers that can be safely shrunk to 32-bit pointers. I don't know how good it is in practice, having nev

Isn't it sufficient to compare 64 bits at a time? Then the oracle becomes rather useless. Many current memcmp implementations use such large comparisons because they avoid hard-to-predict data-dependent branches for extracting the spec

Compilers do inter-procedural register allocation and use custom calling conventions for local calls (where “local” can be quite large with LTO), while preserving ABI externally. This means that clobbering a callee-saved register without sa

Except for max_align_t (which is broken even for scalar types on some targets, and doesn't help with vector types by design), all these things were available long before standardization. So I'm not sure if this is a compelling arg
