[Bug bootstrap/87013] Error: junk at end of line, first unrecognized character is `i'

But there are still assemblers out there that do not support it, so now that we enable the formerly latent is_stmt logic, we'd better make sure the assembler can deal with it. for gcc/ChangeLog PR bootstrap/87013 * configure.ac: Check for .loc is_stmt support. * configure, config.in: Rebuilt. * dwarf2out.c (dwarf2out_source_line): Skip is_stmt if not supported.

I wanted to make sure that the compiler passed the related point, but I don't know how to verify this (the machine is still compiling). So I assume the patch is working. I attached the config.log.

I've also manually tested manually removing the #define HAVE_GAS_LOC_STMT in auto-host.h, and checked that the compiler wouldn't output is_stmt directives. (It would still emit negate_stmt opcodes when generating line number programs itself)

This patch should be enough to avoid the problem, provided that gcc/configure and gcc/config.in are regenerated after putting the configure.ac change in. I'll turn that into a proper patch eventually, but I'd appreciate confirmation that it does solve the problem indeed. Thanks,

That's not the problem, this error is supposed to happen, because your compiler
doesn't recognise the -qversion option.

This is the problem.
Try compiling the source below using the command above, adding -save-temps, and
then look at the resulting .s file. See why your assembler can't process it (do
you even have an assembler for your target?)
