This means fewer instances of arm.AsmFull, which I'd like to remove eventually if possible.
Memory references (`*m` in LLVM IR inline assembly) need a pointer type starting in LLVM 14. This is a bit inconvenient and requires a new API in the go-llvm package. Instead of doing that, I'd like to remove support for memory references from AsmFull (and possibly AsmFull entirely if possible: it's hard to use correctly). This breaks tinygo.org/x/drivers/ws2812 for AVR, ARM, and RISC-V which need to be updated. Probably using CGo.

Tested with tinygo-org/drivers#401 which was merged, and worked as expected. Is there something else I am missing here or can we merge now? |

For details, see: * tinygo-org/drivers#401 * tinygo-org/tinygo#2790 Essentially, this updates the inline assembly to the current best practice.

I doubt inline assembly is used in many places. But the docs need to be updated, for which I've created a PR: tinygo-org/tinygo-site#258 |
