lld/test/COFF/pdb-relative-source-lines.test

   1 Test the linker line tables on roughly the following example:
   2
   3 ==> foo.h <==
   4 void bar(void);
   5 inline void foo(void) {
   6   bar();
   7 }
   8 ==> pdb_lines_1.c <==
   9 #include "foo.h"
  10 int main(void) {
  11   foo();
  12   return 42;
  13 }
  14 ==> pdb_lines_2.c <==
  15 void bar(void) {
  16 }

  20 /pdbsourcepath: only sets the directory that relative paths are considered
  21 relative to, so this test needs to pass relative paths to lld-link for:
  22 1. The input obj files
  23 2. The /pdb: switch
  24 3. The lld-link invocation itself
  25 To achieve this, put all inputs of the lld-link invocation (including lld-link
  26 itself) in a temp directory that's cwd and then make sure to only use relative
  27 arguments when calling ./lld-link below.
