I see.
Point 1 is definitively incorrect. I interpreted asembler wrong:

Thank you Iain. Amazing debugging skills.
BTW. `import std;` was because dustmite reduced original import to just that.
Original import was `import std.math.algebraic : sqrt;`
But you already figured thi

Interesting enough, GDC 10.2 does inline `poly` instantiation with all the
constants.

--- Comment #1 from Witold Baryluk ---
PS. LDC 1.23.0 - 1.32.0 produce optimal code. LDC 1.22.0 a bit worse (due to
use of x87 codegen), and 1.21 and older fail to inline `ldexp`, but still
inline `poly` and `floor` perfectly.

It works. Thank you.
Any chance this will be in gcc 12.x? I work a lot on Debian Linux, and I doubt
I will have gcc trunk or gcc 13 available any time soon.
Also weirdly gcc does not inline this function

Similarly, dec, add, sub, are affected, as well mul.

Current codegen on gcc 12 on 64-bit x86:

Hmm. It appears that using `import core.stdc.string : memcmp;` actually
resolves the problem. It looks like my manually declaration of memcmp for some
reason disabled optimisations for memcmp.

A typo in the example (godbolt is good), I forgot the `.ptr`:

int recognize3(const char* s) {
return memcmp(s, "stract class".ptr, 12) =

Thanks for looking into that. I just wanted to update that this still
suboptimal in current gcc trunk 20201226. While clang produces superior code.
