--- Comment #3 from Visda <Visda.vokhshoori at microchip dot com> --- I looked at GCC 11 release notes, and found the fix https://gcc.gnu.org/pipermail/gcc-patches/2020-May/546494.html Please correct me if I am wrong. Given where we are in our release cycle, we decided to postpone pulling in this patch. For now, I fixed this in our local branch. We will get the new behaviour when we move up to GCC 11+. Thanks. FYI: My local fix is: diff --git a/gcc/toplev.c b/gcc/toplev.c index bdf021e828a..e476c109cb4 100644 --- a/gcc/toplev.c +++ b/gcc/toplev.c @@ -1050,7 +1050,10 @@ open_auxiliary_file (const char *ext) char *filename; FILE *file; - filename = concat (aux_base_name, ".", ext, NULL); +#ifdef _BUILD_AVR3 + if (strcmp (ext, "su") == 0 && flag_stack_usage) + filename = concat (lbasename(aux_base_name), ".", ext, NULL); + else +#endif + filename = concat (aux_base_name, ".", ext, NULL); file = fopen (filename, "w"); if (!file) fatal_error (input_location, "can%'t open %s for writing: %m", filename); @@ -1898,7 +1901,7 @@ lang_dependent_init (const char *name) init_asm_output (name); /* If stack usage information is desired, open the output file. */ - if (flag_stack_usage) + if (flag_stack_usage +#ifdef _BUILD_AVR3 && !flag_generate_lto +#endif) stack_usage_file = open_auxiliary_file ("su"); }
