LDFLAGS always deduplicated

[Kawanaao]

In continuation of the -mllvm flag, the release did not fix the problem, since for some reason only LDFLAGS was deduplicated, I did a little debugging of the function that adds these arguments without duplicates, the results look like this

If I understand correctly, then case " $addres $dups in" ignores the list of flags that can be left as is It's also worth clarifying that this only happens with LDFLAGS, other flags remain correct, they pass this function, but do not cause a traversal via for

Now you use different arguments as in the previous bug: Instead of -Xclang -mllvm (separated by space) you use -Xclang=-mllvm. Using a space instead should work now.

The other could have been fixed simpler already before: Add -Xclang=-mllvm to the array FLAG_ARGS_WITH_PARAMS.

Before I release this fix, please try:

1. Does adding -Xclang=-mllvm to the array FLAG_ARGS_WITH_PARAMS really fix the issue for you?
2. Is there anything else which should be added to FLAG_ARGS_WITH_PARAMS like -Xclang -mmlir and/or -Xclang=mmlir? (I am not familiar with clang arguments.)

Oh, I’m just trying to go through all the possible options for specifying arguments, simply and with the task of arguments through spaces, LDFLAGS turns out to be incorrect, that is, it is not affected in any way by FLAG_ARGS_WITH_PARAMS, case in simply removes duplicates

Just as I see - bashrc seems to just ignore that the arguments are separated by =, it feels like there is a problem in the deduplication mechanism, or it does not work on flags intended for C/C++, in the previous release (v22.2) -Xclang -mllvm -flag was not deduplicated for CFLAGS CXXFLAGS FFLAGS FCFLAGS F77FLAGS, as an example build.log of libmd on version v22.2:

Regarding the additional flags of the second nesting, these could be

1. -Xclang -load -Xclang plugin.so (depricated, fplugin new alternative)
2. -Xclang -add-plugin -Xclang plugin-name
3. -Xclang -plugin-arg-<plugin-name> -Xclang <flag or arg>
4. -Xclang -plugin-opt -Xclang opt1 -Xclang -plugin-opt -Xclang emit-llvm

These are the ones I know and have used, I'm not familiar with the others

Can you try with the head, please? (Only 10-flags.sh needs to be updated.)

Ah, I didn’t quite understand about head, for some reason the last commit was not shown hah

I tried it now, everything works great! :) There were no errors, but I’ll try to run through all the packages
