This generates trash in the 27 ".init" section since the contribution from crtbegin.o is only 7 28 bytes. The linker pads it to 16 bytes with a single 0x90 byte, and 29 two 0x00000090 ints, which generates a segmentation violation when 30 executed. This macro forces the assembler to do the padding, since 31 it knows what it is doing. */ 32 33#define FORCE_INIT_SECTION_ALIGN asm (ALIGN_ASM_OP ## " 16") 34#define FORCE_FINI_SECTION_ALIGN FORCE_INIT_SECTION_ALIGN 35 36/* Add "sun" to the list of symbols defined for SVR4. */ 37#undef CPP_PREDEFINES 38#define CPP_PREDEFINES \ 39 "-Dunix -D__svr4__ -D__SVR4 -Dsun -Asystem(svr4)" 40 41#undef CPP_SPEC 42#define CPP_SPEC "%(cpp_cpu) \ 43 %{compat-bsd:-iwithprefixbefore ucbinclude -I/usr/ucbinclude}" 44 45#undef LIB_SPEC 46#define LIB_SPEC \ 47 "%{compat-bsd:-lucb -lsocket -lnsl -lelf -laio} %{!shared:%{!symbolic:-lc}}" 48 49#undef ENDFILE_SPEC 50#define ENDFILE_SPEC "crtend.o%s %{pg:crtn.o%s}%{!pg:crtn.o%s}" 51 52#undef STARTFILE_SPEC 53#define STARTFILE_SPEC "%{!shared: \ 54 %{!symbolic: \ 55 %{pg:gcrt1.o%s}%{!pg:%{p:mcrt1.o%s}%{!p:crt1.o%s}}}}\ 56 %{pg:gmon.o%s} crti.o%s \ 57 %{ansi:values-Xc.o%s} \ 58 %{!ansi: \ 59 %{traditional:values-Xt.o%s} \ 60 %{!traditional:values-Xa.o%s}} \ 61 crtbegin.o%s" 62 63/* This should be the same as in svr4.h, except with -R added. */ 64#undef LINK_SPEC 65#define LINK_SPEC \ 66 "%{h*} %{v:-V} \ 67 %{b} %{Wl,*:%*} \ 68 %{static:-dn -Bstatic} \ 69 %{shared:-G -dy -z text} \ 70 %{symbolic:-Bsymbolic -G -dy -z text} \ 71 %{G:-G} \ 72 %{YP,*} \ 73 %{R*} \ 74 %{compat-bsd: \ 75 %{!YP,*:%{pg:-Y P,/usr/ucblib:/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib} \ 76 %{!pg:%{p:-Y P,/usr/ucblib:/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib} \ 77 %{!p:-Y P,/usr/ucblib:/usr/ccs/lib:/usr/lib}}} \ 78 -R /usr/ucblib} \ 79 %{!compat-bsd: \ 80 %{!YP,*:%{pg:-Y P,/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib} \ 81 %{!pg:%{p:-Y P,/usr/ccs/lib/libp:/usr/lib/libp:/usr/ccs/lib:/usr/lib} \ 82 %{!p:-Y P,/usr/ccs/lib:/usr/lib}}}} \ 83 %{Qy:} %{!Qn:-Qy}" 84 85/* This defines which switch letters take arguments. 86 It is as in svr4.h but with -R added. */ 87 88#undef SWITCH_TAKES_ARG 89#define SWITCH_TAKES_ARG(CHAR) \ 90 (DEFAULT_SWITCH_TAKES_ARG(CHAR) \ 91 || (CHAR) == 'R' \ 92 || (CHAR) == 'h' \ 93 || (CHAR) == 'z') 94 95#define STDC_0_IN_SYSTEM_HEADERS 96
