  int main() {}
  Fedora Rawhide: gcc -o main.s main.c -gdwarf-5 -S -gno-as-loc-support -dA

But it is hand edited, Besides DWARF simplification I removed the .text 
assembly instructions (and put `.long 0` there) to make it arch-independent 
which was my original intention. But then I remember the DWARF assembly is not 
fully arch-independent anyway so to prevent some false failures in buildbots 
again I kept there that `# REQUIRES: x86` anyway. One could try to remove the 
REQUIRES if one really wanted to test the bots. Still I am not sure if it did 
not cause any buildbots failure as the buildbots are down these days, incl. 
Apple Green Bot.

[Lldb-commits] [PATCH] D97721: [lldb] Support DWARF-5 DW_FORM_line_strp (used by GCC)

2021-03-02 Thread Konrad Wilhelm Kleine via Phabricator via lldb-commits 
kwk added a comment.

@jankratochvil out of curiosity. Can you give a pointer to what the C program 
looks like that produces the object code? I know GCC might change and no longer 
produce this code so it's better to have the obj code instead. But still I'm 
not nearly close to understanding

Looks good.

If you make the function return type `void`, this will go away.
