NAME

       llvm-tli-checker - TargetLibraryInfo vs library checker

SYNOPSIS

       llvm-tli-checker [options] [library-file…]

DESCRIPTION

       llvm-tli-checker  compares  TargetLibraryInfo’s  opinion  of  the  availability of library
       functions against the set of functions exported by the specified library files,  reporting
       any disagreements between TLI’s opinion and whether the function is actually present. This
       is primarily useful for vendors to ensure the TLI for their target  is  correct,  and  the
       compiler  will  not “optimize” some code sequence into a library call that is not actually
       available.

EXAMPLE

          $ llvm-tli-checker --triple x86_64-scei-ps4 example.so
          TLI knows 466 symbols, 235 available for 'x86_64-scei-ps4'

          Looking for symbols in 'example.so'
          Found 235 global function symbols in 'example.so'
          Found a grand total of 235 library symbols
          << TLI yes SDK no:  '_ZdaPv' aka operator delete[](void*)
          >> TLI no  SDK yes: '_ZdaPvj' aka operator delete[](void*, unsigned int)
          << Total TLI yes SDK no:  1
          >> Total TLI no  SDK yes: 1
          == Total TLI yes SDK yes: 234
          FAIL: LLVM TLI doesn't match SDK libraries.

OPTIONS

       --dump-tli
              Print  “available”/”not  available”  for  each  library  function,   according   to
              TargetLibraryInfo’s  information  for  the  specified triple, and exit. This option
              does not read any input files.

       --help, -h
              Print a summary of command line options and exit.

       --libdir=<directory>
              A base directory to prepend to each library file path. This is handy when there are
              a  number  of library files all in the same directory, or a list of input filenames
              are kept in a response file.

       --report=<level>
              The amount of information to report.  <level> can be summary, discrepancy, or full.
              A  summary  report  gives  only  the  count  of  matching and mis-matching symbols;
              discrepancy lists the mis-matching symbols; and full lists  all  symbols  known  to
              TLI, matching or mis-matching. The default is discrepancy.

       --separate
              Read  and report a summary for each library file separately.  This can be useful to
              identify library files that don’t contribute anything that TLI knows about. Implies
              –report=summary (can be overridden).

       --triple=<triple>
              The triple to use for initializing TargetLibraryInfo.

       @<FILE>
              Read command-line options and/or library names from response file <FILE>.

EXIT STATUS

       llvm-tli-checker  returns  0 even if there are mismatches. It returns a non-zero exit code
       if there is an unrecognized option, or no input files are provided.
