Hi @yonghong-song , Thanks for doing this.
I have a doubt, regarding clang behavior, is this relevant to this.
Consider the following test case --
extern global_var;
int main(){}
Now when compiled with clang -g test.c, In file ELF[DWARF] file
their is no, DebugInfo for `global_var`.
While gcc compiled binary gcc -g test.c. has DebugInfo[DWARF]
DW_TAG_variable
DW_AT_name ("global_var")
DW_AT_decl_file ("/test.c)
DW_AT_decl_line (1)
DW_AT_decl_column (0x0c)
DW_AT_type (0x00000039 "int")
DW_AT_external (true)
DW_AT_declaration (true)
Is this relevant ? Does this patch, adds support for this in clang ? I mean
`DIGlobalVariable` related stuff in clang generated Debug Metadata ? seems to,
but still confirming.
Maybe I can use this, to build DWARF related DebugInfo on top of this.
