hans added a comment.
The build system folks replied saying they're not using symlinks, but hard
links for compiler inputs. Dropping the `-s` flag in the repro above
demonstrates this.
Here's a new version of the reproducer that's a little less convoluted:
$ echo 1, 2, 3 > /tmp/foo.h
$ ln /tmp/foo.h /tmp/bar.h
$ cat > /tmp/a.cc
int foo_table[] = {
#include "/tmp/foo.h"
};
int bar_table[] = {
#include "/tmp/bar.h"
};
$ build/bin/clang -E -o - /tmp/a.cc
# 1 "/tmp/a.cc"
# 1 "<built-in>" 1
# 1 "<built-in>" 3
# 437 "<built-in>" 3
# 1 "<command line>" 1
# 1 "<built-in>" 2
# 1 "/tmp/a.cc" 2
int foo_table[] = {
# 1 "/tmp/foo.h" 1
1, 2, 3
# 3 "/tmp/a.cc" 2
};
int bar_table[] = {
# 1 "/tmp/foo.h" 1 <------ Should be bar.h.
1, 2, 3
# 6 "/tmp/a.cc" 2
};
