We define _INCLUDE_LONGLONG 25 to prevent nlist.h from defining __STDC_32_MODE__ (no longlong 26 support). We define __STDCPP__ to get certain system headers 27 (notably assert.h) to assume standard preprocessor behavior in C++. 28 We define _XOPEN_SOURCE_EXTENDED when we define _HPUX_SOURCE to avoid 29 non standard hpux variants in _INCLUDE_XOPEN_SOURCE_EXTENDED. */ 30 #undef TARGET_OS_CPP_BUILTINS 31 #define TARGET_OS_CPP_BUILTINS() \ 32 do \ 33 { \ 34 builtin_assert ("system=hpux"); \ 35 builtin_assert ("system=unix"); \ 36 builtin_define ("__hp9000s800"); \ 37 builtin_define ("__hp9000s800__"); \ 38 builtin_define ("__hpux"); \ 39 builtin_define ("__hpux__"); \ 40 builtin_define ("__unix"); \ 41 builtin_define ("__unix__"); \ 42 builtin_define ("__STDC_EXT__"); \ 43 if (c_dialect_cxx ()) \ 44 { \ 45 builtin_define ("_HPUX_SOURCE"); \ 46 builtin_define ("_REENTRANT"); \ 47 builtin_define ("_INCLUDE_LONGLONG"); \ 48 builtin_define ("__STDCPP__"); \ 49 builtin_define ("_LARGEFILE_SOURCE"); \ 50 builtin_define ("_LARGEFILE64_SOURCE"); \ 51 if (flag_pa_unix >= 1995) \ 52 { \ 53 builtin_define ("_XOPEN_UNIX"); \ 54 builtin_define ("_XOPEN_SOURCE_EXTENDED"); \ 55 } \ 56 } \ 57 else if (flag_iso) \ 58 { \ 59 if (flag_isoc94) \ 60 builtin_define ("_INCLUDE__STDC_A1_SOURCE"); \ 61 } \ 62 else \ 63 { \ 64 builtin_define ("_HPUX_SOURCE"); \ 65 builtin_define ("_REENTRANT"); \ 66 if (preprocessing_trad_p ()) \ 67 { \ 68 builtin_define ("hp9000s800"); \ 69 builtin_define ("hppa"); \ 70 builtin_define ("hpux"); \ 71 builtin_define ("unix"); \ 72 builtin_define ("__CLASSIC_C__"); \ 73 builtin_define ("_PWB"); \ 74 builtin_define ("PWB"); \ 75 } \ 76 if (flag_pa_unix >= 1995) \ 77 { \ 78 builtin_define ("_XOPEN_UNIX"); \ 79 builtin_define ("_XOPEN_SOURCE_EXTENDED"); \ 80 } \ 81 } \ 82 if (TARGET_SIO) \ 83 builtin_define ("_SIO"); \ 84 else \ 85 { \ 86 builtin_define ("__hp9000s700"); \ 87 builtin_define ("__hp9000s700__"); \ 88 builtin_define ("_WSIO"); \ 89 } \ 90 } \ 91 while (0) 92 93 #define CPP_SPEC "%{threads: -D_REENTRANT -D_DCE_THREADS}" 94 95 /* We can debug dynamically linked executables on hpux9; we also want 96 dereferencing of a NULL pointer to cause a SEGV. */ 97 #undef LINK_SPEC 98 #if ((TARGET_DEFAULT | TARGET_CPU_DEFAULT) & MASK_PA_11) 99 #define LINK_SPEC \ 100 "%{!mpa-risc-1-0:%{!march=1.0:%{static:-L/lib/pa1.1 -L/usr/lib/pa1.1 }}}\ 101 %{!shared:%{p:-L/lib/libp %{!static:\ 102 %nwarning: consider linking with '-static' as system libraries with\n\ 103 %n profiling support are only provided in archive format}}}\ 104 %{!shared:%{pg:-L/lib/libp %{!static:\ 105 %nwarning: consider linking with '-static' as system libraries with\n\ 106 %n profiling support are only provided in archive format}}}\ 107 %{!shared:%{!static:%{rdynamic:-E}}}\ 108 -z %{mlinker-opt:-O} %{!shared:-u main}\ 109 %{static:-a archive} %{shared:-b}" 110 #else 111 #define LINK_SPEC \ 112 "%{!shared:%{p:-L/lib/libp %{!static:\ 113 %nwarning: consider linking with '-static' as system libraries with\n\ 114 %n profiling support are only provided in archive format}}}\ 115 %{!shared:%{pg:-L/lib/libp %{!static:\ 116 %nwarning: consider linking with '-static' as system libraries with\n\ 117 %n profiling support are only provided in archive format}}}\ 118 %{!shared:%{!static:%{rdynamic:-E}}}\ 119 -z %{mlinker-opt:-O} %{!shared:-u main}\ 120 %{static:-a archive} %{shared:-b}" 121 #endif 122 123 /* Like the default, except no -lg. */ 124 #undef LIB_SPEC 125 #define LIB_SPEC \ 126 "%{!shared:\ 127 %{!p:%{!pg:\ 128 %{!threads:-lc %{static:%{!nolibdld:-a shared -ldld -a archive -lc}}}\ 129 %{threads:-lcma -lc}}}\ 130 %{p:%{!pg:-lc %{static:%{!nolibdld:-a shared -ldld -a archive -lc}}}}\ 131 %{pg:-lc %{static:%{!nolibdld:-a shared -ldld -a archive -lc}}}}" 132 133 #undef THREAD_MODEL_SPEC 134 #define THREAD_MODEL_SPEC "%{!threads:single}%{threads:dce}" 135 136 /* Under hpux10, the normal location of the `ld' and `as' programs is the 137 /usr/ccs/bin directory. */ 138 139 #ifndef CROSS_DIRECTORY_STRUCTURE 140 #undef MD_EXEC_PREFIX 141 #define MD_EXEC_PREFIX "/usr/ccs/bin/" 142 #endif 143 144 /* Under hpux10, the normal location of the various *crt*.o files is 145 the /usr/ccs/lib directory.
