1 ; This testcase checks to make sure that we can write PDB files. It 2 ; works by first reading a known good PDB file and dumping the contents 3 ; to YAML. Then it tries to reconstruct as much of the original PDB as 4 ; possible, although depending on what flags are specified when generating 5 ; the YAML, the PDB might be missing data required for any standard tool 6 ; to recognize it. Finally, it dumps the same set of fields from the newly 7 ; constructed PDB to YAML, and verifies that the YAML is the same as the 8 ; original YAML generated from the good PDB. Note that when doing the 9 ; final comparison it must dump the original and the new pdb without any 10 ; stream metadata, since the layout of the MSF file might be different 11 ; (for example if we don't write the entire stream) 12 ; 13 ; RUN: llvm-pdbutil pdb2yaml -stream-metadata -stream-directory \ 14 ; RUN: -pdb-stream -tpi-stream -module-syms %p/Inputs/empty.pdb > %t.1 15 ; RUN: llvm-pdbutil yaml2pdb -pdb=%t.2 %t.1 16 ; RUN: llvm-pdbutil pdb2yaml -pdb-stream -tpi-stream \ 17 ; RUN: -module-syms -no-file-headers %p/Inputs/empty.pdb > %t.3 18 ; RUN: llvm-pdbutil pdb2yaml -pdb-stream -tpi-stream \ 19 ; RUN: -module-syms -no-file-headers %t.2 > %t.4 20 ; RUN: diff %t.3 %t.4 21
