* Miscellaneous low-risk changes preparing for _ISOMAC testsuite.Zack Weinberg2017-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are a grab bag of changes where the testsuite was using internal symbols of some variety, but this was straightforward to fix, and the fixed code should work with or without the change to compile the testsuite under _ISOMAC. Four of these are just more #include adjustments, but I want to highlight sysdeps/powerpc/fpu/tst-setcontext-fpscr.c, which appears to have been written before the advent of sys/auxv.h. I think a big chunk of this file could be replaced by a simple call to getauxval, but I'll let someone who actually has a powerpc machine to test on do that. dlfcn/tst-dladdr.c was including ldsodefs.h just so it could use DL_LOOKUP_ADDRESS to print an additional diagnostic; as requested by Carlos, I have removed this. math/test-misc.c was using #ifndef NO_LONG_DOUBLE, which is an internal configuration macro, to decide whether to do certain tests involving 'long double'. I changed the test to #if LDBL_MANT_DIG > DBL_MANT_DIG instead, which uses only public float.h macros and is equivalent on all supported platforms. (Note that NO_LONG_DOUBLE doesn't mean 'the compiler doesn't support long double', it means 'long double is the same as double'.) tst-writev.c has a configuration macro 'ARTIFICIAL_LIMIT' that the Makefiles are expected to define, and sysdeps/unix/sysv/linux/Makefile was using the internal __getpagesize in the definition; changed to sysconf(_SC_PAGESIZE) which is the POSIX equivalent. ia64-linux doesn't supply 'clone', only '__clone2', which is not defined in the public headers(!) All the other clone tests have local extern declarations of __clone2, but tst-clone.c doesn't; it was getting away with this because include/sched.h does declare __clone2. * nss/tst-cancel-getpwuid_r.c: Include nss.h. * string/strcasestr.c: No need to include config.h. * sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: Include sys/auxv.h. Don't include sysdep.h. * sysdeps/powerpc/tst-set_ppr.c: Don't include dl-procinfo.h. * dlfcn/tst-dladdr.c: Don't include ldsodefs.h. Don't use DL_LOOKUP_ADDRESS. * math/test-misc.c: Instead of testing NO_LONG_DOUBLE, test whether LDBL_MANT_DIG is greater than DBL_MANT_DIG. * sysdeps/unix/sysv/linux/Makefile (CFLAGS-tst-writev.c): Use sysconf (_SC_PAGESIZE) instead of __getpagesize in definition of ARTIFICIAL_LIMIT. * sysdeps/unix/sysv/linux/tst-clone.c [__ia64__]: Add extern declaration of __clone2.
