We define _INCLUDE_LONGLONG 27 to prevent nlist.h from defining __STDC_32_MODE__ (no longlong 28 support). We define __STDCPP__ to get certain system headers 29 (notably assert.h) to assume standard preprocessor behavior in C++. */ 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 if (c_dialect_cxx ()) \ 43 { \ 44 builtin_define ("_HPUX_SOURCE"); \ 45 builtin_define ("_INCLUDE_LONGLONG"); \ 46 builtin_define ("__STDC_EXT__"); \ 47 builtin_define ("__STDCPP__"); \ 48 } \ 49 else if (!flag_iso) \ 50 { \ 51 builtin_define ("_HPUX_SOURCE"); \ 52 if (preprocessing_trad_p ()) \ 53 { \ 54 builtin_define ("hp9000s800"); \ 55 builtin_define ("hppa"); \ 56 builtin_define ("hpux"); \ 57 builtin_define ("unix"); \ 58 builtin_define ("__CLASSIC_C__"); \ 59 builtin_define ("_PWB"); \ 60 builtin_define ("PWB"); \ 61 } \ 62 else \ 63 builtin_define ("__STDC_EXT__"); \ 64 } \ 65 if (TARGET_SIO) \ 66 builtin_define ("_SIO"); \ 67 else \ 68 { \ 69 builtin_define ("__hp9000s700"); \ 70 builtin_define ("__hp9000s700__"); \ 71 builtin_define ("_WSIO"); \ 72 } \ 73 } \ 74 while (0) 75 76 #define CPP_SPEC "%{threads: -D_REENTRANT -D_DCE_THREADS}" 77 78 /* We can debug dynamically linked executables on hpux9; we also want 79 dereferencing of a NULL pointer to cause a SEGV. */ 80 #undef LINK_SPEC 81 #if ((TARGET_DEFAULT | TARGET_CPU_DEFAULT) & MASK_PA_11) 82 #define LINK_SPEC \ 83 "%{!mpa-risc-1-0:%{!shared:-L/lib/pa1.1 -L/usr/lib/pa1.1 }}\ 84 %{!shared:%{p:-L/lib/libp %{!static:\ 85 %nWarning: consider linking with `-static' as system libraries with\n\ 86 %n profiling support are only provided in archive format}}}\ 87 %{!shared:%{pg:-L/lib/libp %{!static:\ 88 %nWarning: consider linking with `-static' as system libraries with\n\ 89 %n profiling support are only provided in archive format}}}\ 90 -z %{mlinker-opt:-O} %{!shared:-u main}\ 91 %{static:-a archive} %{shared:-b}" 92 #else 93 #define LINK_SPEC \ 94 "%{!shared:%{p:-L/lib/libp %{!static:\ 95 %nWarning: consider linking with `-static' as system libraries with\n\ 96 %n profiling support are only provided in archive format}}}\ 97 %{!shared:%{pg:-L/lib/libp %{!static:\ 98 %nWarning: consider linking with `-static' as system libraries with\n\ 99 %n profiling support are only provided in archive format}}}\ 100 -z %{mlinker-opt:-O} %{!shared:-u main}\ 101 %{static:-a archive} %{shared:-b}" 102 #endif 103 104 /* Like the default, except no -lg. */ 105 #undef LIB_SPEC 106 #define LIB_SPEC \ 107 "%{!shared:\ 108 %{!p:%{!pg:\ 109 %{!threads:-lc %{static:%{!nolibdld:-a shared -ldld -a archive -lc}}}\ 110 %{threads:-lcma -lc_r}}}\ 111 %{p:%{!pg:-lc %{static:%{!nolibdld:-a shared -ldld -a archive -lc}}}}\ 112 %{pg:-lc %{static:%{!nolibdld:-a shared -ldld -a archive -lc}}}}" 113 114 #undef THREAD_MODEL_SPEC 115 #define THREAD_MODEL_SPEC "%{!threads:single}%{threads:dce}" 116 117 /* Under hpux10, the normal location of the `ld' and `as' programs is the 118 /usr/ccs/bin directory. */ 119 120 #ifndef CROSS_COMPILE 121 #undef MD_EXEC_PREFIX 122 #define MD_EXEC_PREFIX "/usr/ccs/bin/" 123 #endif 124 125 /* Under hpux10, the normal location of the various *crt*.o files is 126 the /usr/ccs/lib directory.
