| 131 | 176 /* Solaris libc and libm implement multiple behaviours for various |
| 177 interfaces that have changed over the years in different versions of the | |
| 178 C standard. 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. */ | |
