These yaml test cases appear to have been affected by PR41836 Right now what happens is that these empty .bss sections are merged into .data, then the .data output section ends up having a zero virtual size, and it is discarded from the output after addresses are assigned. However, we've already assigned OutputSections to Chunks, so we don't correctly report the zero-sized chunks that were in there as having been discarded. Soon, we will report them as discarded, so these test cases need to be updated to have a non-zero size so they aren't discarded. llvm-svn: 360476

Consider this example program with an inline function "foo":
|
|
|
|
==> foo.h <==
|
|
extern int global;
|
|
__inline void foo() {
|
|
++global;
|
|
}
|
|
void bar();
|
|
==> pdb_comdat_main.c <==
|
|
#include "foo.h"
|
|
int main(void) {
|
|
foo();
|
|
bar();
|
|
return 42;
|
|
}
|
|
==> pdb_comdat_bar.c <==
|
|
#include "foo.h"
|
|
void bar(void) {
|
|
foo();
|
|
}
|
|
|
|
Both object files will contain debug info for foo, but only the debug info from
|
|
pdb_comdat_main.obj should be included in the PDB.
