Test the linker line tables on roughly the following example:
==> foo.h <==
void bar(void);
inline void foo(void) {
bar();
}
==> pdb_lines_1.c <==
#include "foo.h"
int main(void) {
foo();
return 42;
}
==> pdb_lines_2.c <==
void bar(void) {
}
$ clang-cl -fdebug-compilation-dir . -no-canonical-prefixes -c -Z7 pdb_lines*.c
$ obj2yaml pdb_lines_1.obj > pdb_lines_1_relative.yaml
$ obj2yaml pdb_lines_2.obj > pdb_lines_2_relative.yaml
/pdbsourcepath: only sets the directory that relative paths are considered
relative to, so this test needs to pass relative paths to lld-link for:
1. The input obj files
2. The /pdb: switch
3. The lld-link invocation itself
To achieve this, put all inputs of the lld-link invocation (including lld-link
itself) in a temp directory that's cwd and then make sure to only use relative
arguments when calling ./lld-link below.
RUN: rm -rf %t
RUN: mkdir %t
RUN: cp lld-link %t/lld-link
RUN: cd %t
RUN: yaml2obj %S/Inputs/pdb_lines_1_relative.yaml -o %t/pdb_lines_1_relative.obj
RUN: yaml2obj %S/Inputs/pdb_lines_2_relative.yaml -o %t/pdb_lines_2_relative.obj
RUN: ./lld-link -debug "-pdbsourcepath:c:\src" -entry:main -nodefaultlib -out:out.exe -pdb:out.pdb pdb_lines_1_relative.obj pdb_lines_2_relative.obj
RUN: llvm-pdbutil pdb2yaml -ipi-stream -modules -module-files -module-syms -subsections=lines,fc %t/out.pdb | FileCheck %s
RUN: ./lld-link -debug "-pdbsourcepath:/usr/src" -entry:main -nodefaultlib -out:out.exe -pdb:out.pdb pdb_lines_1_relative.obj pdb_lines_2_relative.obj
RUN: llvm-pdbutil pdb2yaml -ipi-stream -modules -module-files -module-syms -subsections=lines,fc %t/out.pdb | FileCheck --check-prefix=POSIX %s
Also check without -pdbsourcepath
RUN: ./lld-link -debug -entry:main -nodefaultlib -out:out.exe -pdb:out.pdb pdb_lines_1_relative.obj pdb_lines_2_relative.obj
RUN: llvm-pdbutil pdb2yaml -modules -module-files -module-syms -subsections=lines,fc %t/out.pdb | FileCheck --check-prefix=ABSOLUTE %s
Clean up copy of large binary copied into temp directory to avoid bloat.
RUN: rm -f ./lld-link || true
