- LLVM can use external disassembler library for various purposes (now it's used
- only for examining code produced by JIT). This option will enable usage of
- `udis86 <http://udis86.sourceforge.net/>`_ x86 (both 32 and 64 bits)
- disassembler library.
-
To configure LLVM, follow these steps:
#. Change directory into the object root directory:
/* Define to 1 if you have the `shell32' library (-lshell32). */
#cmakedefine HAVE_LIBSHELL32 ${HAVE_LIBSHELL32}
-/* Define to 1 if you have the `udis86' library (-ludis86). */
-#undef HAVE_LIBUDIS86
-
/* Define to 1 if you have the 'z' library (-lz). */
#cmakedefine HAVE_LIBZ ${HAVE_LIBZ}
/* Define to 1 if your <sys/time.h> declares `struct tm'. */
#undef TM_IN_SYS_TIME
-/* Define if use udis86 library */
-#undef USE_UDIS86
-
/* Type of 1st arg on ELM Callback */
#cmakedefine WIN32_ELMCB_PCSTR ${WIN32_ELMCB_PCSTR}
/* Define to 1 if you have the `shell32' library (-lshell32). */
#undef HAVE_LIBSHELL32
-/* Define to 1 if you have the `udis86' library (-ludis86). */
-#undef HAVE_LIBUDIS86
-
/* Define to 1 if you have the `z' library (-lz). */
#undef HAVE_LIBZ
/* Define to 1 if your <sys/time.h> declares `struct tm'. */
#undef TM_IN_SYS_TIME
-/* Define if use udis86 library */
-#undef USE_UDIS86
