The behaviour is controlled by linking corresponding 179 values-*.o objects. Each of these objects contain alternate definitions 180 of one or more variables that the libraries use to select which 181 conflicting behaviour they should exhibit. There are two sets of these 182 objects, values-X*.o and values-xpg*.o. 183 184 The values-X[ac].o objects set the variable _lib_version. The Studio C 185 compilers use values-Xc.o with either -Xc or (since Studio 12.6) 186 -pedantic to select strictly conformant ISO C behaviour, otherwise 187 values-Xa.o. Since -pedantic is a diagnostic option only in GCC, we 188 need to specifiy the -std=c* options and -std=iso9899:199409. We 189 traditionally include -ansi, which affects C and C++, and also -std=c++* 190 for consistency. 191 192 The values-xpg[46].o objects define either or both __xpg[46] variables, 193 selecting XPG4 mode (__xpg4) and conforming C99/SUSv3 behavior (__xpg6). 194 195 Since GCC 5, gcc defaults to -std=gnu11 or higher, so we link 196 values-xpg6.o to get C99 semantics. Besides, most of the runtime 197 libraries always require C99 semantics. 198 199 Since only one instance of _lib_version and __xpg[46] takes effekt (the 200 first in ld.so.1's search path), we only link the values-*.o files into 201 executable programs. */ 202#undef STARTFILE_ARCH_SPEC 203#define STARTFILE_ARCH_SPEC \ 204 "%{!shared:%{!symbolic: \ 205 %{ansi|std=c*|std=iso9899\\:199409:values-Xc.o%s; :values-Xa.o%s} \ 206 %{std=c90|std=gnu90:values-xpg4.o%s; :values-xpg6.o%s}}}" 207 208#if defined(HAVE_LD_PIE) && defined(HAVE_SOLARIS_CRTS) 209#define STARTFILE_CRTBEGIN_SPEC "%{static:crtbegin.o%s; \ 210 shared|" PIE_SPEC ":crtbeginS.o%s; \ 211 :crtbegin.o%s}" 212#else 213#define STARTFILE_CRTBEGIN_SPEC "crtbegin.o%s" 214#endif 215 216#if ENABLE_VTABLE_VERIFY 217#if SUPPORTS_INIT_PRIORITY 218#define STARTFILE_VTV_SPEC \ 219 "%{fvtable-verify=none:%s; \ 220 fvtable-verify=preinit:vtv_start_preinit.o%s; \ 221 fvtable-verify=std:vtv_start.o%s}" 222#define ENDFILE_VTV_SPEC \ 223 "%{fvtable-verify=none:%s; \ 224 fvtable-verify=preinit:vtv_end_preinit.o%s; \ 225 fvtable-verify=std:vtv_end.o%s}" 226#else /* !SUPPORTS_INIT_PRIORITY */ 227#define STARTFILE_VTV_SPEC \ 228 "%{fvtable-verify=*: \ 229 %e-fvtable-verify=%* is not supported in this configuration}" 230#define ENDFILE_VTV_SPEC "" 231#endif /* !SUPPORTS_INIT_PRIORITY */ 232#else /* !ENABLE_VTABLE_VERIFY */ 233#define STARTFILE_VTV_SPEC "" 234#define ENDFILE_VTV_SPEC "" 235#endif /* !ENABLE_VTABLE_VERIFY */ 236 237/* Link -lasan early on the command line.
