Comments in assembler files for some architectures are indexed as identifiers

[fstachura]

See for example: https://elixir.bootlin.com/linux/latest/source/arch/arc/kernel/head.S#L25 https://elixir.bootlin.com/linux/latest/source/arch/sh/kernel/entry-common.S#L8 https://elixir.bootlin.com/linux/latest/source/arch/arm/kernel/entry-common.S#L43 (end of the line, after @)

This is likely due to the fact, that different architectures have different comment syntax in GNU Assembler. https://en.wikipedia.org/wiki/GNU_Assembler

Do you have any idea to address this? The indexer must be able, just from the file content and its filepath, to determine how parsing should be done. That sounds hard, or project specific.

I don't see any good way to detect architecture from the assembler file alone, I think this would have to be fixed in a different way for every project. Another problem is that most assembler files in Linux codebase are in arch/, however, some are not. See https://elixir.bootlin.com/linux/latest/source/drivers/memory/ti-emif-sram-pm.S

OK, last solution would be to make the general parsing we do be more generic to other assembly language files. For example (^|\s)!\s being the start of a line comment seems pretty safe from a quick grep. Same for ;.

We wouldn't want to have each project definition having to define parsing of assembly files. That's too complex for little benefits.

This sounds low priority to me though.
